One fundamental problem in sentiment analysis is categorization of sentiment polarity. Given a piece of written text, the problem is to categorize the text into one specific sentiment polarity, positive or negative (or neutral). Based on the scope of the text, there are three distinctions of sentiment polarity categorization, namely the document level, the sentence level, and the entity and aspect level. Consider a review “I like multimedia features but the battery life sucks.†This sentence has a mixed emotion. The emotion regarding multimedia is positive whereas that regarding battery life is negative. Hence, it is required to extract only those opinions relevant to a particular feature (like battery life or multimedia) and classify them, instead of taking the complete sentence and the overall sentiment. In this paper, we present a novel approach to identify pattern specific expressions of opinion in text.

Amazon Product Review Sentiment Analysis with Machine Learningijtsrd
Users of Amazons online shopping service are allowed to leave feedback for the items they buy. Amazon makes no effort to monitor or limit the scope of these reviews. Although the amount of reviews for various items varies, the reviews provide easily accessible and abundant data for a variety of applications. This paper aims to apply and expand existing natural language processing and sentiment analysis research to data obtained from Amazon. The number of stars given to a product by a user is used as training data for supervised machine learning. Since more people are dependent on online products these days, the value of a review is increasing. Before making a purchase, a buyer must read thousands of reviews to fully comprehend a product. In this day and age of machine learning, however, sorting through thousands of comments and learning from them would be much easier if a model was used to polarize and learn from them. We used supervised learning to polarize a massive Amazon dataset and achieve satisfactory accuracy.

Basic introduction of opinion mining and sentiment analysis , challenges faced during opinion mining, Sentiment classification at various levels and application of mining and sentiment analysis
Sentimental analysis is a context based mining of text, which extracts and identify subjective information from a text or sentence provided. Here the main concept is extracting the sentiment of the text using machine learning techniques such as LSTM Long short term memory . This text classification method analyses the incoming text and determines whether the underlined emotion is positive or negative along with probability associated with that positive or negative statements. Probability depicts the strength of a positive or negative statement, if the probability is close to zero, it implies that the sentiment is strongly negative and if probability is close to1, it means that the statement is strongly positive. Here a web application is created to deploy this model using a Python based micro framework called flask. Many other methods, such as RNN and CNN, are inefficient when compared to LSTM.

POWER QUALITY IMPROVEMENT BY SSSC AND STATCOM USING PI CONTROLLERJournal For Research
This paper presents the enhancement of voltage stability using Static Synchronous compensator (STATCOM) and Static Synchronous series compensator (SSSC). In recent past years, along with the rapid increasing electrical power requirement has caused system to be heavily loaded leading to voltage instability. Under this condition there may be insufficient reactive power causing voltage to drop at various buses. The result would be the occurrence of voltage collapse which leads to total blackout of the whole system. FACT controllers have been used for solving various stability control problems. In this paper, SSSC and STATCOM are used to investigate the effect of these devices in controlling active and reactive powers to maintain voltage stability. The PI Controller is used to tune the circuit and to provide the zero signal error. Simulation results have been presented in MATLAB/Simulink environment for two machines four buses system.

Education, philosophy and politics is the tripos that occupies a central place within the Western tradition defining the canon and genres, as well as the practices of political and pedagogical institutions that to a large extent have endured in one form or other premised upon the notion of logos and dialogical exchange as the educational basis for the pursuit of the good life. It is difficult to separate these elements historically, and from ancient times they have together formed the cultural basis of life in the polis : in a word, education as the political philosophy of democratic citizenship, representation and active participation in the polis.
Due to the fast growth of World Wide Web the online communication has increased. In recent times the communication focus has shifted to social networking. In order to enhance the text methods of communication such as tweets, blogs and chats, it is necessary to examine the emotion of user by studying the input text. Online reviews are posted by customers for the products and services on offer at a website portal. This has provided impetus to substantial growth of online purchasing making opinion analysis a vital factor for business development. To analyze such text and reviews sentiment analysis is used. Sentiment analysis is a sub domain of Natural Language Processing which acquires writer’s feelings about several products which are placed on the internet through various comments or posts. It is used to find the opinion or response of the user. Opinion may be positive, negative or neutral. In this paper a review on sentiment analysis is done and the challenges and issues involved in the process are discussed. The approaches to sentiment analysis using dictionaries such as SenticNet, SentiFul, SentiWordNet, and WordNet are studied. Dictionary-based approaches are efficient over a domain of study. Although a generalized dictionary like WordNet may be used, the accuracy of the classifier get affected due to issues like negation, synonyms, sarcasm, etc.

Mining of product reviews at aspect levelijfcstjournal
Today’s world is a world of Internet, almost all work can be done with the help of it, from simple mobile
phone recharge to biggest business deals can be done with the help of this technology. People spent their
most of the times on surfing on the Web; it becomes a new source of entertainment, education,
communication, shopping etc. Users not only use these websites but also give their feedback and
suggestions that will be useful for other users. In this way a large amount of reviews of users are collected
on the Web that needs to be explored, analyse and organized for better decision making. Opinion Mining or
Sentiment Analysis is a Natural Language Processing and Information Extraction task that identifies the
user’s views or opinions explained in the form of positive, negative or neutral comments and quotes
underlying the text. Aspect based opinion mining is one of the level of Opinion mining that determines the
aspect of the given reviews and classify the review for each feature. In this paper an aspect based opinion
mining system is proposed to classify the reviews as positive, negative and neutral for each feature.
Negation is also handled in the proposed system. Experimental results using reviews of products show the
effectiveness of the system.

Co-Extracting Opinions from Online ReviewsEditor IJCATR
Exclusion of opinion targets and words from online reviews is an important and challenging task in opinion mining. The
opinion mining is the use of natural language processing, text analysis and computational process to identify and recover the subjective
information in source materials. This paper propose a Supervised word alignment model, which identifying the opinion relation. Rather
than this paper focused on topical relation, in which to extract the relevant information or features only from a particular online reviews.
It is based on feature extraction algorithm to identify the potential features. Finally the items are ranked based on the frequency of
positive and negative reviews. Compared to previous methods, our model captures opinion relation and feature extraction more precisely.
One of the most advantages that our model obtain better precision because of supervised alignment model. In addition, an opinion
relation graph is used to refer the relationship between opinion targets and opinion words.
Sentiment Analysis Using Hybrid Approach: A SurveyIJERA Editor
Sentiment analysis is the process of identifying people’s attitude and emotional state’s from language. The main objective is realized by identifying a set of potential features in the review and extracting opinion expressions about those features by exploiting their associations. Opinion mining, also known as Sentiment analysis, plays an important role in this process. It is the study of emotions i.e. Sentiments, Expressions that are stated in natural language. Natural language techniques are applied to extract emotions from unstructured data. There are several techniques which can be used to analysis such type of data. Here, we are categorizing these techniques broadly as ”supervised learning”, ”unsupervised learning” and ”hybrid techniques”. The objective of this paper is to provide the overview of Sentiment Analysis, their challenges and a comparative analysis of it’s techniques in the field of Natural Language Processing.
An Improved sentiment classification for objective word.IJSRD
Sentiment classification is an ongoing field and interesting area of research because of its application in various fields. Customer sentiments play a very important role in daily life. Currently, Sentiment classification focused on subjective statements and ignores objective statements which also carry sentiment. During the sentiment classification, problem is faced due to the ambiguous sense (meaning) of words and negation words. In word sense disambiguation method semantic scores calculated from SentiWordNet of WordNet glosses terms. The correct sense of the word is extracted and determined similarity in WordNet glosses terms. SentiWordNet extract first sense of word which used in general sense. This work aims at improving the sentiment classification by modifying the sentiment values returned by SentiWordNet and compare classification accuracy of support vector machine and naïve bays.
TOWARDS AUTOMATIC DETECTION OF SENTIMENTS IN CUSTOMER REVIEWSijistjournal
Opinions Play important role in the process of knowledge discovery or information retrieval and can be considered as a sub discipline of Data Mining. A major interest has been received towards the automatic extraction of human opinions from web documents. The sole purpose of Sentiment Analysis is to facilitate online consumers in decision making process of purchasing new products. Opinion Mining deals with searching of sentiments that are expressed by Individuals through on-line reviews,surveys, feedback,personal blogs etc. With the vast increase in the utilization of Internet in today's era a similar increase has been seen in the use of blog's,reviews etc. The person who actually uses these reviews or blog's is mostly a consumer or a manufacturer. As most of the customers of the world are buying & selling product on-line so it becomes company's responsibility to make their product updated. In the current scenario companies are taking product reviews from the customers and on the basis of product reviews they are able to know in which they are lacking or strong this can be accomplished with the help of sentiment analysis. Therefore Our objective of our research is to build a tool which can automatically extract opinion words and find out their polarity by using dictionary,This actually reduces the manual effort of reading these reviews and to evaluate them. The research also illustrates the benefits of using Unstructured text instead of training data which expensive . In this research effort we demonstrate a method which is based on rules where product reviews are extracted from review containing sites and analysis is done, so that a person may know whether a particular product review is positive or negative or neutral. The system will utilize a existing knowledge base for calculate positive and negative scores and on the basis of that decide whether a product is recommended or not.

Sentiment Features based Analysis of Online Reviewsiosrjce
IOSR Journal of Computer Engineering (IOSR-JCE) is a double blind peer reviewed International Journal that provides rapid publication (within a month) of articles in all areas of computer engineering and its applications. The journal welcomes publications of high quality papers on theoretical developments and practical applications in computer technology. Original research papers, state-of-the-art reviews, and high quality technical notes are invited for publications.
With the rapid growth in ecommerce, reviews for popular products on the web have grown rapidly.
Although these reviews are important for making decisions, it is difficult to read all the reviews.
Automating the opinion mining process was identified as a solution for the problem. Although there are
algorithms for opinion mining, an algorithm with better accuracy is needed. A feature and smiley based
algorithm was developed which extracts product features from reviews based on feature frequency and
generates an opinion summary based on product features.
The algorithm was tested on downloaded customer reviews. The sentences were tagged, opinion words
were extracted and opinion orientations were identified using semantic orientation of opinion words and
smileys. Since the precision values for feature extraction and both precision and recall values for opinion
orientation identification were improved by the new algorithm, it is more successful in opinion mining of
customer reviews.

Image Binarization for the uses of Preprocessing to Detect Brain Abnormality ...Journal For Research
Computerized MR of brain image binarization for the uses of preprocessing of features extraction and brain abnormality identification of brain has been described. Binarization is used as intermediate steps of many MR of brain normal and abnormal tissues detection. One of the main problems of MRI binarization is that many pixels of brain part cannot be correctly binarized due to the extensive black background or the large variation in contrast between background and foreground of MRI. Proposed binarization determines a threshold value using mean, variance, standard deviation and entropy followed by a non-gamut enhancement that can overcome the binarization problem. The proposed binarization technique is extensively tested with a variety of MRI and generates good binarization with improved accuracy and reduced error.
A Research Paper on BFO and PSO Based Movie Recommendation System | J4RV4I1016Journal For Research
The objective of this work is to assess the utility of personalized recommendation system (PRS) in the field of movie recommendation using a new model based on neural network classification and hybrid optimization algorithm. We have used advantages of both the evolutionary optimization algorithms which are Particle swarm optimization (PSO) and Bacteria foraging optimization (BFO). In its implementation a NN classification model is used to obtain a movie recommendation which predict ratings of movie. Parameters or attributes on which movie ratings are dependent are supplied by user's demographic details and movie content information. The efficiency and accuracy of proposed method is verified by multiple experiments based on the Movie Lens benchmark dataset. Hybrid optimization algorithm selects best attributes from total supplied attributes of recommendation system and gives more accurate rating with less time taken. In present scenario movie database is becoming larger so we need an optimized recommendation system for better performance in terms of time and accuracy.
IoT based Digital Agriculture Monitoring System and Their Impact on Optimal U...Journal For Research
Although precision agriculture has been adopted in few countries, the greenhouse based modern agriculture industry in India still needs to be modernized with the involvement of technology for better production and cost control. In this paper we proposed a multifunction model for smart agriculture based on IoT. Due to variable atmospheric circumstances these conditions sometimes may vary from place to place in large farmhouse, which makes very difficult to maintain the uniform condition at all the places in the farmhouse manually. Soil and environment properties are sensed and periodically sent to cloud network through IoT. Analysis on cloud data is done for water requirement, total production and maintaining uniform environment conditions throughout greenhouse farm. Proposed model is beneficial for increase in agricultural production and for cost control and real time monitoring of farm.

HCI BASED APPLICATION FOR PLAYING COMPUTER GAMES | J4RV4I1014Journal For Research
This paper describes a command interface for games based on hand gestures and voice command defined by postures, movement and location. The system uses computer vision requiring no sensors or markers by the user. In voice command the speech recognizer, recognize the input from the user. It stores and passes command to the game, action takes place. We propose a simple architecture for performing real time colour detection and motion tracking using a webcam. The next step is to track the motion of the specified colours and the resulting actions are given as input commands to the system. We specify blue colour for motion tracking and green colour for mouse pointer. The speech recognition is the process of automatically recognizing a certain word spoken by a particular speaker based on individual information included in speech waves. This application will help in reduction in hardware requirement and can be implemented in other electronic devices also.
A REVIEW ON DESIGN OF PUBLIC TRANSPORTATION SYSTEM IN CHANDRAPUR CITY | J4RV4...Journal For Research
As we know the population of Chandrapur City has increased so far in this years and with that has increased the vehicles causing high traffic volume & rise in pollution. But the transportation system in Chandrapur City is still the same. To reduce the traffic volume & pollution, we have to study & design the new transportation system in Chandrapur City. The system would be as similar to Nagpur City with the implementation of Star City Buses. In this Study we would first compare the speed of various vehicles. Collection of population details of Chandrapur City, approximate number of vehicles running on road, collection of data with respect to Ticket fares in Nagpur City- whether it is according to Kilometers or places to be reached, calculation of Ticket Fares for Chandrapur City on the basis data collected. By all these, the best mode of transport in City can be studied. On the basis of above data collected from various respected fields, we will then proceed for the Design part of urban transport system in Chandrapur City. For Design purpose, firstly we have to mark the centre of the City, when the centre is decided; we will then select the Bus Terminus. From centre of the city, we would prefer to select the routes of the Buses. One route will be for the city side like Jatpura Gate, Pathanpura Gate. One route will be for Ballarpur going road. The other one for Mul going road, then next for Nagpur road. We could decide as many routes once we get the clear idea about all data. By getting all this details, the next step is to design the destination points of Buses.

LABORATORY STUDY OF STRONG, MODERATE AND WEAK SANDSTONES | J4RV4I1012Journal For Research
Sandstones from seven different hydroelectric projects have been assessed to compare their water-related properties and engineering parameters and the comprehensive analysis has been presented. The study has been done by categorizing the sandstones in to three categories i.e. weak, moderate & strong sandstones. The study leads to four broad inferences: (1), there could be very large variation between two sandstones; e.g., here, sandstone S2, S4 & S5, vis-à-vis other two strong sandstones, is superior in all respects. (2), the four weak sandstones differ in respect of some – not all – properties and parameters. (3), none of the four weak sandstones is better than the other two in respect of all properties and parameters. (4), moderate sandstone shows higher values of shear strength parameters in comparison to all the sandstones (including stronger sandstones also) except S3 strong sandstone. In respect of individual properties, the grain density of all sandstones is similar, though their bulk densities, apparent porosity and water content show great variation. The weak, moderate and strong sandstones show qualitative difference in their uniaxial compressive strength and wave velocity (compression and shear, both); and the two are directly proportional. The study clearly demonstrates that there is no one-to-one correspondence between any two properties and parameters, but there is a diffused and/ or qualitative relationship between different sandstones, or certain properties and parameters of a particular variant.
DESIGN ANALYSIS AND FABRICATION OF MANUAL RICE TRANSPLANTING MACHINE | J4RV4I...Journal For Research
Need of rice transplanting machine is growing nowadays because of unique feature seeding in well sequence and well manners. This will save too much efforts of human being. Class of people who uses this kind of machine is farmers and they are having poor economic background. To feed growing population is a huge challenge. Importation of rice will lead to drain out the economy of the country. Mechanization of paddy sector will lead to higher productivity with releasing of work force to other sectors. The objective of this project is to design a paddy transplanting mechanism to transplant paddy seedling by small scale farmers in the country. Hence, this is considered as an activity that needed mechanization. For mechanization the modeling and simulation evaluated for hand operated rice seeding machine, which is help the farmers to planting more and more amount of rice in good quality with low energy consumption and less harm to the environment. India is predominately an agricultural country with rice as one of its main food crop. It Produce about 80 million tons rice annually which is about 22% of the world rice production. Culturally transplanting of young seeding is preferred over direct seeding for better yield and better crop management practice. But this operation requires large amount of manpower (about 400 Man-Hour/ha) and task is very laborious involving working in stopping posture and moving in muddy field.

AN INTEGRATED APPROACH TO REDUCE INTRA CITY TRAFFIC AT COIMBATORE | J4RV4I1002Journal For Research
Coimbatore (11.0168°N,76.9558°E) is a fast developing cosmopolitan city with large number of industries and educational institutions. The development has lead to a large number of vehicles causing heavy traffic. The traffic congestion at Coimbatore has been a major problem which causes traffic jams and accidents. The major reason for traffic has been the mofussil buses that operate in the city. Around 1300 mofussil buses enter into the city, these buses play an important role in traffic congestion. The best solution is to construct a centralized bus stand at the outskirts of the city. This would reduce the traffic, accidents and also leads to development of the outskirts of the city. A suitable location near the city with sufficient road access to connecting cities has been chosen and the bus terminus has been designed, modeled with all facilities and features.
A REVIEW STUDY ON GAS-SOLID CYCLONE SEPARATOR USING LAPPLE MODEL | J4RV4I1001Journal For Research
Cyclone is the most commonly used device to separate dust particles from gas and dust flow. The performance of cyclone separator can be measured in terms of collection efficiency and pressure drop. Parameters like Inlet Flow velocity, the particle size distribution in feed, dimensions of inlet and outlet ducts and cyclone affects the performance of cyclone significantly. Various Mathematical models used for calculation of cut off diameter of separator, flow rate, target efficiency and no. of vortex inside the cyclone to design and study to check the performance of existing cyclone separator. Also new dimensions can be design with help of models. Here, in this study the efficiency achieved with Lapple model cumulatively 86.47%.
During past few years, brain tumor segmentation in CT has become an emergent research area in the field of medical imaging system. Brain tumor detection helps in finding the exact size and location of tumor. An efficient algorithm is proposed in this project for tumor detection based on segmentation and morphological operators. Firstly quality of scanned image is enhanced and then morphological operators are applied to detect the tumor in the scanned image. The problem with biopsy is that the patient has to be hospitalized and also the results (around 15%) give false negative. Scan images are read by radiologist but it's a subjective analysis which requires more experience. In the proposed work we segment the renal region and then classify the tumors as benign or malignant by using ANFIS, which is a non-invasive automated process. This approach reduces the waiting time of the patient.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Abstract
One fundamental problem in sentiment analysis is categorization of sentiment polarity. Given a piece of written text, the problem
is to categorize the text into one specific sentiment polarity, positive or negative (or neutral). Based on the scope of the text, there
are three distinctions of sentiment polarity categorization, namely the document level, the sentence level, and the entity and aspect
level. Consider a review “I like multimedia features but the battery life sucks.” This sentence has a mixed emotion. The emotion
regarding multimedia is positive whereas that regarding battery life is negative. Hence, it is required to extract only those opinions
relevant to a particular feature (like battery life or multimedia) and classify them, instead of taking the complete sentence and the
overall sentiment. In this paper, we present a novel approach to identify pattern specific expressions of opinion in text.
Keywords: Sentiment analysis, Natural language processing, and Pattern Recognition
_______________________________________________________________________________________________________
I. INTRODUCTION
A vital part of the information era has been to find out the opinions of other people. In the pre-web era, it was customary for an
individual to ask his or her friends and relatives for opinions before making a decision. Organizations conducted opinion polls,
surveys to understand the sentiment and opinion of the general public towards its products or services.
Sentiment analysis or Opinion mining, as it is sometimes called, is one of many areas of computational studies that deal with
opinion oriented natural language processing. Such opinion oriented studies include among others, genre distinctions, emotion and
mood recognition, ranking, relevance computations, perspectives in text, text source identification and opinion oriented
summarization. Sentiment analysis has turned out as an exciting new trend in social media with a gamut of practical applications
that range from applications in business (marketing intelligence; product and service bench marking and improvement),
applications as sub component technology.
Sentiment is an attitude, thought, or judgment prompted by feeling. Sentiment analysis is also known as opinion mining.
Sentiment analysis or opinion mining is one of the major tasks of NLP (Natural Language Processing). It has gain much attention
in recent years. Internet is a resourceful place with respect to sentiment information. From a user’s point of view, people are able
to post their own content through various social media, such as forums, micro-blogs, or online social networking sites. From a
researcher’s perspective, many social media sites release their application programming interfaces (APIs), prompting data
collection and analysis by researchers and developers.
Sentiment Analysis, an area of Natural Language Processing (NLP), is used to classify the reviews using the sentiment of the
words into positive or negative. Using the sentiment expressed in the words, opinions on any entity can be categorized into positive
or negative. For example, the sentence, ‘I am not excited by this product though it is quite cheap’ expresses a negative sentiment
about the product. The degree of the sentiment used is also taken into consideration. For example, ‘I love this product’ indicates a
more positive sentiment than the sentence ‘I like this product’. Apart from regular adjectives like ‘good’, ‘bad’ and ‘very good’,
conjunctions like ‘but’, ‘although”, ‘while’ also have a say in the overall polarity of the sentence.
There is a vast amount of information available on the Web which can assist individuals and organization in decision making
processes but at the same time present many challenges as organizations and individuals attempt to analyze and comprehend the
collective opinion of others. Unfortunately finding opinion sources, monitoring them and then analyzing them are herculean tasks.
It is not possible to manually find opinion sources online, extract sentiments from them and then to express them in a standard
format.
In recent years, the explosion of social networking sites, blogs and review sites provide a lot of information. Millions of people
express uninhibited opinions about various product features and their nuances. This forms an active feedback which is of
importance not only to the companies developing the products, but also to their rivals and several other potential customers.

II. REVIEW WORKS
Researchers use semantic analysis for Chinese opinion related expression extraction. They identifies relations as, topic and
sentiment located in the same sub-sentence and quite close to each other, topic and sentiment located in adjacent sub-sentences
and the two sub-sentences are parallel in structure, topic and sentiment located in different sub-sentences, either being adjacent or
not, but the different sub sentences are independent of each other, no parallel structures any more [1].
Researchers use phrase dependency parsing for opinion mining. In dependency grammar, structure is determined by the relation
between a head and its dependents. The dependent is a modifier or complement and the head plays a more important role in
determining the behaviours of the pair. They want to compromise between the information loss of the word level dependency in
dependency parsing as it does not explicitly provide local structures and syntactic categories of phrases and the information gain
in extracting long distance relations. Hence they extend the dependency tree node with phrases [2].
Some researchers used frequent item sets to extract the most relevant features from a domain and pruned it to obtain a subset of
features. They extract the nearby adjectives to a feature as an opinion word regarding that feature. Using a seed set of labeled
Adjectives, which they manually develop for each domain, they further expand it using WordNet and use them to classify the
extracted opinion words as positive or negative [3].
Some researchers proposed a joint sentiment topic model to probabilistically model the set of features and sentiment topics using
HMM-LDA. It is an unsupervised system which models the distribution of features and opinions in a review and is thus a generative
model [4].
The sentence level sentiment analysis is closely related to subjectivity analysis. At this level each sentence is analyzed and its
opinion is determined as positive, negative or neutral [5]. The aspect level sentiment analysis aims at identifying the target of the
opinion. The basis of this approach is that every opinion has a target and an opinion without a target is of limited use [6].
Unsupervised algorithms like the Pointwise Mutual Information and Latent Dirichlet allocation have been proposed and the
results have been discussed in [7] and [8] respectively. Many supervised algorithms exist like the Naive Bayes Classifier and
Support Vector Machines.
Kemburu developed a content based flight reservation system that made flight recommendation to users based on their date,
time of travel preferences, previous flight reservation history and real time flight information [9].
An integral part of any system design is system performance evaluation. Shani et al. in his work highlighted the different
methodologies that can be used for evaluating the performance of a recommender system [10]. Recommender systems based on
collaborative filtering often ignore the social elements of decision making and advice seeking [11].
Bedi et al. in their work proposed a recommender system that used knowledge stored in the form of ontologies to make
predictions [11]. In their system information received only from ‘trusted agents’ was used for prediction thereby aiming towards
overcoming the social element based shortcomings that plague most recommendation systems [11]. With an aim to making flight
travel pleasant, Liu et al proposed a heart rate controlled in-flight music recommendation system [12]. Heart rate is an estimation
of stress level. Based on heart rate that is higher/lower than normal calm/uplift music is played on the system to stabilize the
heartbeat of a traveller [12].
III. PROPOSED METHOD AND RESULTS
Given a text containing multiple features and varied opinions, the objective is to extract expressions of opinion describing a target
feature and classify it as positive or negative. We now describe the proposed algorithm.
Algorithm:
Input a text and check whether the sentiment is positive, negative or neutral.
Prerequisites:
Book1.csv: It is an excel file written in csv format where positive and negative words and its corresponding values are stored.
We set the value of positive words +1 and negative word -1. It is our main database file.
Input file: It is an input file which is used for sentiment analysis where some texts are stored.
Data structure: Here we use arraylist named Filebean which have two attributes key and values. We use two arraylists. For
database file named as ‘filecontent’ and for input file named as ‘wordlist’.
1) Step-1: Read the contents of file store it into the Filebean.
Step-1.1: Read the contents of the file.
Step-1.2: For each line split the line with the delimiter “,” and store in the Filebean.
2) Step-2: Read the contents of the input file and store it in the Filebean ‘wordlist’. Here we consider three cases: -
Step-2.1: Remove the ‘.’ And ‘,’ by replacing with the blank character.
Step-2.2: Split the word using space and store the word into the wordlist. If there is space that means, there is more than
one word.
Step-2.3: If the file contains one word so we store it directly into the wordlist.

3) Step-3: compare between the contents of two arraylist filecontent and arraylist.
Step-3.1: check whether the two keys/words are equal or not.
If equal, then add the value of the key of the filecontent together.
Step-3.2: If the sum is less than zero then the result is positive.
If the sum is equal to zero then the result is neutral otherwise, if the sum is greater than zero the result is negative.
IV. RESULT
Test-1:
Database file name: Book1.csv
Input file name: inputfile1.txt
