The latest generation of emoticons which are called as emojis that is largely being used in mobile
communications as well as in social media. In past few years, more than ten billion emojis were used on Twitter.
Emojis which are known as the Unicode graphic symbols, which are basically used as shorthand to express the
concepts and ideas of the people. For smaller number of well-known emoticons, their meanings or sentiments
are well known but there are thousands of emojis so extracting their sentiments is difficult. The Emoji Sentiment
Ranking method which is used to evaluate a sentiment mapping of emojis by using sentiment polarity such as
negative, neutral, or positive. The sentimental classification of tweets with and without emoticons are very much
different.Finally, the method also gives representation of sentiments and a better visualization in the form of a
sentimental Bar.
Evaluation of Support Vector Machine and Decision Tree for Emotion Recognitio...journalBEEI
In this paper, the performance of Support Vector Machine (SVM) and Decision Tree (DT) in classifying emotions from Malay folklores is presented. This work is the continuation of our storytelling speech synthesis work to add emotions for a more natural storytelling. A total of 100 documents from children short stories are collected and used as the datasets of the text-based emotion recognition experiment. Term Frequency-Inverse Document Frequency (TF-IDF) is extracted from the text documents and classified using SVM and DT. Four types of common emotions, which are happy, angry, fearful and sad are classified using the two classifiers. Results showed that DT outperformed SVM by more than 22.2% accuracy rate. However, the overall emotion recognition is only at moderate rate suggesting an improvement is needed in future work. The accuracy of the emotion recognition should be improved in future studies by using semantic feature extractors or by incorporating deep learning for classification.
How could a product or service is reasonably evaluated by anyone in the shortest time? A million dollar
question but it is having a simple answer: Sentiment analysis. Sentiment analysis is consumers review on
products and services which helps both the producers and consumers (stakeholders) to take effective and
efficient decision within a shortest period of time. Producers can have better knowledge of their products
and services through the sentiment analysis (ex. positive and negative comments or consumers likes and
dislikes) which will help them to know their products status (ex. product limitations or market status).
Consumers can have better knowledge of their interested products and services through the sentiment
analysis (ex. positive and negative comments or consumers likes and dislikes) which will help them to know
their deserving products status (ex. product limitations or market status). For more specification of the
sentiment values, fuzzy logic could be introduced. Therefore, sentiment analysis with the help of fuzzy logic
(deals with reasoning and gives closer views to the exact sentiment values) will help the producers or
consumers or any interested person for taking the effective decision according to their product or service
interest.
Determine the sentiment of sentence that is positive or negative based on the presence of part of
speech tag, the emoticons present in the sentences. For this research we use the most popular microblogging sit
twitter for sentiment orientation. In this paper we want to extract tweets form the twitter related to the product
like mobile phones, home appliances, vehicle etc. After retrieving tweets we perform some preprocessing on it
like remove retweets, remove tweets containing few words with minimum threshold of length five, remove tweets
containing only urls. After this the remaining tweets are pre-processed like that transform all letters of the
tweets to the lower case then remove punctuation from the tweets because it reduces the accuracy of result.
After this remove extra white spaces from the tweets, then we apply a pos tagger to tag each word. The tuple
after the applying above steps contain (word, pos tag, English-word, stop-word). We are interested in only
tweets that contain opinion and eliminate the remaining non-opinion tweets from the data set. For this we use
the Naïve Bays classification algorithm. After this we use short text classification on tweets i.e., the word having
different meaning in different domain. In order to solve this problem we use two different feature selection
algorithms the mutual information (MI) and the X2 feature selection. At final stage predicting the orientation of
an opinion sentence that is positive or negative as we mentioned above. For this we use two model like unigram
model and opinion miner.
ADAPTIVE VOCABULARY CONSTRUCTION FOR FRUSTRATION INTENSITY MODELLING IN CUSTO...ijcsit
This paper examines emotion intensity prediction in dialogs between clients and customer support
representatives occurring on Twitter. We focus on a single emotion type, namely, frustration, modelling the
user's level of frustration while attempting to predict frustration intensity on the current and next turn,
based on the text of turns coming from both dialog participants. A subset of the Kaggle Customer Support
on Twitter dataset was used as the modelling data, annotated with per-turn frustration intensity ratings.
We propose to represent dialog turns by binary encoded bags of automatically selected keywords to be
subsequently used in a machine learning classifier. To assess the classification quality, we examined two
different levels of accuracy imprecision tolerance. Our model achieved a level of accuracy significantly
higher than a statistical baseline for prediction of frustration intensity for a current turn. However, we did
not find the additional information from customer support turns to help predict frustration intensity of the
next turn, and the reason for that is possibly the stability of user’s frustration level over the course of the
conversation, in other words, the inability of support’s response to exert much influence to user’s initial
frustration level.

sell a product which has bad review, the user blames the eCommerce website rather than manufacturers most of the
times. In some review sites some great audits are included by
the item organization individuals itself so as to make so as to
deliver false positive item reviews. To eliminate these type of
fake product review, we will create a system that finds out the
fake reviews and eliminates all the fake reviews by using
machine learning. We also remove the reviews that are flood
by a marketing agency in order to boost up the ratings of a

Emoji’s sentiment score estimation using convolutional neural network with mu...IJECEIAES
Emojis are any small images, symbols, or icons that are used in social media. Several well-known emojis have been ranked and sentiment scores have been assigned to them. These ranked emojis can be used for sentiment analysis; however, many new released emojis have not been ranked and have no sentiment score yet. This paper proposes a new method to estimate the sentiment score of any unranked emotion emoji from its image by classifying it into the class of the most similar ranked emoji and then estimating the sentiment score using the score of the most similar emoji. The accuracy of sentiment score estimation is improved by using multi-scale images. The ranked emoji image data set consisted of 613 classes with 161 emoji images from three different platforms in each class. The images were cropped to produce multi-scale images. The classification and estimation were performed by using convolutional neural network (CNN) with multi- scale emoji images and the proposed voting algorithm called the majority voting with probability (MVP). The proposed method was evaluated on two datasets: ranked emoji images and unranked emoji images. The accuracies of sentiment score estimation for the ranked and unranked emoji test images are 98% and 51%, respectively.
Emotion detection on social media status in Myanmar language IJECEIAES
Many social media emerged and provided services during these years. Most people, especially in Myanmar, use them to express their emotions or moods, learn subjects, sell products, read up-to-date news, and communicate with each other. Emotion detection on social users makes critical tasks in the opinion mining and sentiment analysis. This paper presents the emotion detection system on social media (Facebook) user status or post written in Myanmar (Burmese) language. Before the emotion detection process, the user posts are pre-processed under segmentation, stemming, part-of-speech (POS) tagging, and stop word removal. The system then uses our preconstructed Myanmar word-emotion Lexicon, M-Lexicon, to extract the emotion words from the segmented POS post. The system provides six types of emotion such as surprise, disgust, fear, anger, sadness, and happiness. The system applies naïve Bayes (NB) emotion classifier to examine the emotion in the case of more than two words with different emotion values are extracted. The classifiers also classify the emotion of the users on their posts. The experiment shows that the system can detect 85% accuracy in NB based emotion detection while 86% in recurrent neural network (RNN).
Text to Emotion Extraction Using Supervised Machine Learning TechniquesTELKOMNIKA JOURNAL
Proliferation of internet and social media has greatly increased the popularity of text
communication. People convey their sentiment and emotion through text which promotes lively
communication. Consequently, a tremendous amount of emotional text is generated on different social
media and blogs in every moment. This has raised the necessity of automated tool for emotion mining from
text. There are various rule based approaches of emotion extraction form text based on emotion intensity
lexicon. However, creating emotion intensity lexicon is a time consuming and tedious process. Moreover,
there is no hard and fast rule for assigning emotion intensity to words. To solve these difficulties, we
propose a machine learning based approach of emotion extraction from text which relies on annotated
example rather emotion intensity lexicon. We investigated Multinomial Naïve Bayesian (MNB) Classifier,
Artificial Neural Network (ANN) and Support Vector Machine (SVM) for mining emotion from text. In our
setup, SVM outperformed other classifiers with promising accuracy.

Word and Sentence Level Emotion Analyzation in Telugu Blog and NewsIJCSEA Journal
Emotion analysis, a recent sub discipline at the crossroads of information retrieval and computational linguistics is becoming increasingly important from application viewpoints of affective computing.Emotion is crucial to identify as it is not open to any objective observation or verification. In this paper, emotion analysis on blog texts has been carried out for a less privileged language, Telugu and the same system has been applied on the English SemEval 2007 affect sensing corpus containing only news headlines. A set of six emotion tags, namely, happy ( ), sad ( ), anger ( ), fear ( ), surprise ( )and disgust ( ), have been selected towards this emotion detection task for reliable and semi-automatic annotation of blog and news data. Conditional Random Field (CRF) based classifier has been applied for recognizing six basic emotion tags for different words of a sentence. The classifier accuracy has been improved by arranging an equal distribution of emotional tags and non-emotional tag. A score based technique has been adopted to calculate and assign tag weights to each of the six emotion tags. A sense based scoring strategy has been applied to identify sentence level emotion scores for the six emotion tags based on the acquired word level emotion tags. Sentence level emotion tagging has been
carried out based on the maximum obtained sentence level emotion scores. Evaluation has been conducted for each emotion class separately on 200 test sentences from each of the Telugu blog and English news data. The system has resulted accuracies of 69.82% and 71.06% for happy, 70.24% and 66.42% for sad, 65.73% and 64.27% for anger, 76.01% and 69.90% for disgust, 72.19% and 73.59% for fear and 70.54% and 66.64% for surprise emotion classes on blog and news test data respectively.

LEADERSHIP ONLY CAN LEAD THE ORGANIZATION TOWARDS IMPROVEMENT AND DEVELOPMENT vivatechijri
This paper is explaining that how only leadership is responsible for sustainable improvement and
growth and only it can lead the organization towards improvement and overall development. Leadership and its
effectiveness are discussed in this research work and also how leadership is a different way of the success of the
organization and different from the traditional management to create true work-culture and good-will of the
organization in the social scene. Leadership is only responsible in bringing positive and negative change in the
organization; if the leadership doesn’t have the concern in the organization, the organization will not be able to
lead in the right direction towards improvement and development.

Structural and Morphological Studies of Nano Composite Polymer Gel Electroly...vivatechijri
n today’s society, we stand before a change in energy scarcity. As our civilization grows, many
countries in thedeveloping world seek to have the standard of living that has been exclusive to a few nations, so
their arises a need in thedevelopment of technology that is compatible enough with the resources provided by
nature in order to have sustainabledevelopment to all class of the society. In order to overcomethe prevailing
challenges of huge energy crises in near future, there is an urgent need for the development of electrical
vehiclesor hybrid electrical vehicles with low CO2 emissions using renewable energy sources. In view of the
above, electrochemicalcapacitors can fulfil the requirements to some extent.Preparation of nano composite
polymer gel electrolyte is the best optional product to overcome these problems. When fillers are added or
dispersed to the polymer gel electrolyte, amorphous or porous nature of electrolyte increases which enhances
the liquid absorbing quality of polymer and helps in removing the drawbacks of polymer gel electrolytes such as
leakage, poor mechanical and thermal stability etc. In this work dispersion of SiO2 nano filler is done in the
[PVdF (HFP)-PC-Mg (ClO4)2] for the synthesis of nano composite PGE [PVdF (HFP)-PC-MgClO4- SiO2].
Optimization and characterization was carried out by using various techniques.

METHODS FOR DETECTION OF COMMON ADULTERANTS IN FOODvivatechijri
Food is essential forliving. Food adulteration deceives consumers and can endanger their health. The
purpose of this document is to list common food adulterant methods commonly found in India. An adulterant is
a substance found in other substances such as food, cosmetics, pharmaceuticals, fuels, or other chemicals that
compromise the safety or effectiveness of that substance. The addition of adulterants is called adulteration. The
most common reason for adulteration is the use of undeclared materials by manufacturers that are cheaper than
the correct and declared ones. The adulterants can be harmful or reduce the effectiveness of the product, or
they can be harmless.

According to a research in 2018, every minute Google conducted 3.88 million searches, other people posted 49,000 photos on Instagram, sent 159,362,760 e-mails, tweeted 473,000 times and watched 4.33 million videos on YouTube. In 2020 it estimated a creation of 1.7 megabytes of knowledge per second per person globally, which translates to about 418 zettabytes during a single year. The magnetic or optical data-storage systems that currently hold this volume of 0s and 1s typically cannot last for quite a century. Running data centres takes vast amounts of energy. In short, we are close to have a substantial data-storage problem which will only become more severe over time. Deoxyribonucleic acid (DNA) are often potentially used for these purposes because it isn't much different from the traditional method utilized in a computer. DNA’s information density is notable, 215 petabytes or 215 million gigabytes of data can be stored in just one gram of DNA. First we can encode all data at a molecular level and then store it in a medium that will last for a while and not become out-dated just like floppy disks. Due to the improved techniques for reading and writing DNA, a rapid increase is observed in the amount of possible data storage in DNA.
The usage of chatbots has increased tremendously since past few years. A conversational interface is an interface that the user can interact with by means of a conversation. The conversation can occur by speech but also by text input. When a chatty interface uses text, it is also described as a chatbot or a conversational medium. During this study, the user experience factors of these so called chatbots were investigated. The prime objective is “to spot the state of the art in chatbot usability and applied human-computer interaction methodologies, to research the way to assess chatbots usability". Two sorts of chatbots are formulated, one with and one without personalisation factors. the planning of this research may be a two-by-two factorial design. The independent variables are the two chatbots (unpersonalised versus personalised) and thus the speci?c task or goal the user are ready to do with the chatbot within the ?nancial ?eld (a simple versus a posh task). The results are that there was no noteworthy interaction effect between personalisation and task on the user experience of chatbots. A signi?cant di?erence was found between the two tasks with regard to the user experience of chatbots, however this variation wasn't because of personalisation.

Cross Platform Development Using Fluttervivatechijri
Today the development of cross-platform mobile application has under the state of compromise. The developers are not willing to choose an alternative of either building the similar app many times for many operating systems or to accept a lowest common denominator and optimal solution that will going to trade the native speed, accuracy for portability. The Flutter is an open-source SDK for creating high-performance, high fidelity mobile apps for the development of iOS and Android. Few significant features of flutter are - Just-in-time compilation (JIT), Ahead- of-time compilation (AOT compilation) into a native (system-dependent) machine code so that the resulting binary file can execute natively. The Flutter’s hot reload functionality helps us to understand quickly and easily experiment, build UIs, add features, and fix bugs. Hot reload works by injecting updated source code files into the running Dart Virtual Machine (VM). With the help of Flutter, we believe that we would be having a solution that gives us the best of both worlds: hardware accelerated graphics and UI, powered by native ARM code, targeting both popular mobile operating systems.
The Internet, today, has become an important part of our lives. The World Wide Web that was once a small and inaccessible data storage service is now large and valuable. Current activities partially or completely integrated into the physical world can be made to a higher standard. All activities related to our daily life are mapped and linked to another business in the digital world. The world has seen great strides in the Internet and in 3D stereoscopic displays. The time has come to unite the two to bring a new level of experience to the users. 3D Internet is a concept that is yet to be used and requires browsers to be equipped with in-depth visualization and artificial intelligence. When this material is included, the Internet concept of material may become a reality discussed in this paper. In this paper we have discussed the features, possible setting methods, applications, and advantages and disadvantages of using the Internet. With this paper we aim to provide a clear view of 3D Internet and the potential benefits associated with this obviously cost the amount of investment needed to be used.
Recommender System (RS) has emerged as a significant research interest that aims to assist users to seek out items online by providing suggestions that closely match their interests. Recommender system, an information filtering technology employed in many items is presented in internet sites as per the interest of users, and is implemented in applications like movies, music, venue, books, research articles, tourism and social media normally. Recommender systems research is usually supported comparisons of predictive accuracy: the higher the evaluation scores, the higher the recommender. One amongst the leading approaches was the utilization of advice systems to proactively recommend scholarly papers to individual researchers. In today's world, time has more value and therefore the researchers haven't any much time to spend on trying to find the proper articles in line with their research domain. Recommender Systems are designed to suggest users the things that best fit the user needs and preferences. Recommender systems typically produce an inventory of recommendations in one among two ways -through collaborative or content-based filtering. Additionally, both the general public and also the non-public used descriptive metadata are used. The scope of the advice is therefore limited to variety of documents which are either publicly available or which are granted copyright permits. Recommendation systems (RS) support users and developers of varied computer and software systems to beat information overload, perform information discovery tasks and approximate computation, among others.

Social media platform and Our right to privacyvivatechijri
The advancement of Information Technology has hastened the ability to disseminate information across the globe. In particular, the recent trends in ‘Social Networking’ have led to a spark in personally sensitive information being published on the World Wide Web. While such socially active websites are creative tools for expressing one’s personality it also entails serious privacy concerns. Thus, Social Networking websites could be termed a double edged sword. It is important for the law to keep abreast of these developments in technology. The purpose of this paper is to demonstrate the limits of extending existing laws to battle privacy intrusions in the Internet especially in the context of social networking. It is suggested that privacy specific legislation is the most appropriate means of protecting online privacy. In doing so it is important to maintain a balance between the competing right of expression, the failure of which may hinder the reaping of benefits offered by Internet technology

A Study of Tokenization of Real Estate Using Blockchain Technologyvivatechijri
Real estate is by far one of the most trusted investments that people have preferred, being a lucrative investment it provides a steady source of income in the form of lease and rents. Although there are numerous advantages, one of the key downsides of real estate investments is lack of liquidity. Thus, even though global real estate investments amount to about twice the size of investments in stock markets, the number of investors in the real estate market is significantly lower. Block chain technology has real potential in addressing the issues of liquidity and transparency, opening the market to even retail investors. Owing to the functionality and flexibility of creating Security Tokens, which are backed by real-world assets, real estate can be made liquid with the help of Special Purpose Vehicles. Tokens of ERC 777 standard, which represent fractional ownership of the real estate can be purchased by an investor and these tokens can also be listed on secondary exchanges. The robustness of Smart Contracts can enable the efficient transfer of tokens and seamless distribution of earnings amongst the investors. This work describes Ethereum blockchainbased solutions to make the existing Real Estate investment system much more efficient.

Abstract :The latest generation of emoticons which are called as emojis that is largely being used in mobile
communications as well as in social media. In past few years, more than ten billion emojis were used on Twitter.
Emojis which are known as the Unicode graphic symbols, which are basically used as shorthand to express the
concepts and ideas of the people. For smaller number of well-known emoticons, their meanings or sentiments
are well known but there are thousands of emojis so extracting their sentiments is difficult. The Emoji Sentiment
Ranking method which is used to evaluate a sentiment mapping of emojis by using sentiment polarity such as
negative, neutral, or positive. The sentimental classification of tweets with and without emoticons are very much
different.Finally, the method also gives representation of sentiments and a better visualization in the form of a
sentimental Bar.
Keywords-Classification of Emoticons, Emoji Sentiment Ranking, Sentiment Bar, Sentiment labels, Sentiment
score.
1. INTRODUCTION
As the use of social media is increasing day by day, emoticons plays a essential role in communication
through technology, and many other devices have provided different forms of pictures that do not use type
punctuations. They provide another range of expressions and feelings through texting that conveys specific
emotions through facial gestures. Nowadays emoticons on smartphones, in chatting, and in many different
applications, have become tremendously popular worldwide. For example, Twitter has become very active
in sharing content with comments. According to statistics, around 500 million of tweets are dispensed per
day. Each tweet expresses different form of emotions.
An emoticon, such as , and many others are used for facial expression. It also allows the peoples to
express their feelings, moods, and emotions, which replaces and enriches a written message with non-verbal
elements. It allows user to understand the feelings of their friends and colleagues in better manner. Some
social network sites and microblogging tools such as Twitter allows individuals to express their feelings or
opinions to specific results. These short messages which are also known as tweets that includes emotions
such as happiness, sadness, anger etc in it. Classification of emoticons is basically done in two categories
such as positive emoticons and negative emotions. Positive emoticons consistof love and joy whereas
negative emoticons consist of sadness and anger.
The simplest forms of representation are the generally denoted as 'emoticon' or 'smiley'. People
from Japan popularized a kind of emoticon called kaomoji where ((kao)=face and (moji)=characters) [6].
Sentiment analysis of text is being done by many researchers but for emoticons still it’s in developing stage
so it’s a need to research more on emoticons and give it a limelight to know all about emoji for future users.

2. RELATED WORK
There are six reported works related to Emoticons found in the literature review.
Georgios Solakidis [1]. In this paper the objective is to evaluate sentiment analysis on multilingual
data, also the paper focuses on study and draw conclusion about subjectivity, polarity and the feelings that
is expressed in user generated content, which mainly consist of free text document. The approach involves
detection and use of self-defining features that available within the data that take accounts in two
emotionally rich features: -a] emoticons b] lists of specific keywords. There is machine learning approach
on collection of training data using evaluating and comparing the result of two separate elements that is
emoticons & keywords. There is graphical comparison between keyword and emoticons on subjectivity
level, polarity level. This system integrates and automates all tasks associated with semi-supervised
emotion detection.
Nasiya Najeeb [2]. This paper proposes different opinion mining techniques for various type of natural
language processing for tracking mood of public about particular product or topic. Many peoples write
opinions in forum, microblogging or review websites. This is useful for analysing the data for companies,
governments, and individuals for tracking automatically feelings and attitudes. Social networks allow users
to express their feeling and convey their emotions via text as well as emoticons. Information in terms of text
are extracted ad clustered into emotions and then classified into positive, negative and neutral. An emoticon
basically affects the sentence when it occurs because it also provides better sentiment expression of a web
user. Text extraction is done manually or automatically after extraction the next step is filtration which
includes emoticon replacements. After filtering the data, various classifiers are used to classify text based
on emotions. The algorithm called as Word emotion technique is used to extract emotion form each word.
Types of emoticons: Textual emoticons: - “:”, “=”,“_”, “,” Graphical emoticons: - this provides better
sentiments e.g. I feel very happy. (using phrase), feel very happy . (using phrase as well as emoticon).
Fei Jiang [3]. A decision tree based user’s context classifier and prediction model is designed to
classify tweets according to emoticons expressed through the emoticons. The emoticons which are
proposed by are used for mapping different emotions such as Love, Happiness, Pity, Furious, Heroic,
Fearful, Disgust, Wonder and Peace [3]. These emotions are mandatory part of human nature that can be
considered. The methodology for user’s context personalization based on emoticons involves two major
phases such as: a) Training Phase b) Testing Phase. Along with words, emoticons also extracted. Emoticons
that are extracted from standard library. A decision tree is generated which is based on classifier and
prediction model for performing emotion classification.
Alexander Hogenboom [4]. Nowadays people increasingly use emoticons to express their feelings or
sentiments. People uses emoticons for products, services organizations, individual issues, events topics and
their attributes through social media (Twitter). As twitter have text message limitations to 140 characters.
So, people uses emoji’s instead of big texts to express their sentiments. Emoticons are ASCII art emoticons
are also called as smileys. Emoticons always adds essence for plain text and convey joy , sadness ,
laughter etc. To exploit or to understand emoji’s in automated system first need to analyse that emoticons
can typically relate to sentiments of the data in which they occur. They affect sentences or paragraphs.
Some paragraphs contain only one emoticon which shows different sentiments, but in other paragraphs
there are multiple use of emoticons so it will affect the sentence in which it occurs. Till now textual based
sentiments were used in twitter. But now people uses emoticon to express their feelings so now it will be
based on lexicon based sentiment analysis for emoticons.
Anthoniraj Amalanathan [5]. They proposed Emoticons Space Model (ESM) for sentiment analysis. In
this paper the ESM technique treats each emoticons differently and also integrates that do not have clear
emotional meaning. ESM simplifies emoticon signals and consistently performs previous state operations.
ESM consist of two phase: -a) Projection Phase:-obtain co-ordinates of the posts are obtained based on
coordinate of words. b) Classification Phase: -Use co-ordinate of the posts as features for supervised
sentiment classification task.
Maryam Hasan [6]. In social media there many tools are widely used by personally to express their
feeling and comments in the form of text message. Detection of emotions in plain text has a wide range of
applications which includes human individual emotions and also public emotions of other people. They
propose new approach in which classifying text messages automatically according their emotional states.
There is one of the model studied that Circumflex Emotional model. This model characterized along two
dimensions a) Valence b) Arousal. The Twitter messages are selected as input data set to the system and in
that data set they provide a very large amount of available group of emotions. Main thing is they used

supervised classifier for to detect classes of multiple emotions. In detection of emotions from the text
messages there are some problem such as sparse and high dimensional feature vectors of messages. For the
tackle of those problem they utilize Lexicon of emotions which uses these steps Designing and
implementing a method that automatically label twitter messages based on the emotions of their authors,
then Resolving the problem of high dimensional feature space in twitter dataset and lastly Achieving
highest accuracy for classifying twitter messages based on their emotional states. The accuracy is compared
with several machine learning algorithms and methods such as SVM, KNN, Decision Tree and Naive
Bayes.
3. PROBLEM DEFINITION
The new generation of emoticons which are known as emoji's that is increasingly being used in mobile
communications as well as in social media. For smaller number of popular emoticons, their sentiments are
well known but there are thousands of emoji's so extracting their sentiments is challenging. The existing
system for exploiting emoticons, classification of emoticons was based only on sentiment score and polarity
but did not use Sentiment Rank and Bar which will provide better understanding of emoticons.
4. METHODOLOGY
The method proposed in this paper aims for automation of sentiment analysis for emoticons. It uses two
main approaches first one is the emoji sentiment lexicon which calculates the sentiment score and the
second one is emoji sentiment ranking which considers ranking and positions of the emoticons for
sentiment analysis.Proposed system also gives graphical representation on sentiments after extracting
emoticons. Fig 4.1: shows System flow diagram for proposed system.

The sentiment of emoticons is evaluated from the sentiment of tweets. In the training phase initially
labelling of the tweets will be done. Sentiment labels can take one of the three values which are negative, neutral
and positive. A label ‘c’ is discrete three valued variables {-1, 0, +1} [5]. After this extraction of emoticons are
done from the tweets by separating the text from emoticons. Then the emoticons are stored in the dataset for
classification and further process. When the user enters the tweet in the text field of Twitter the content classifier
is used for classifying the text and emoticons in that tweet with having access to the dataset. In classification,
Emoji Sentiment Ranking uses the overall mapping of emojis. The position of an emoji is determined by
sentiment score 𝑆and neutrality p0. The sentiment score will be in the range of (-1, +1) and computed as p+ to
p-. The positive emojis will be towards right hand side with green colour, negative ones towards left hand side
with red colour and the neutral emojis with yellow colour.
The frequently used emoticons are given a higher rank and less frequently emoticons are given as
lower rank while others are given as mid-point rank. Emojis, on the other hand, can appear in groups and also at
the end of the tweets. In the sentiment distribution for the set of relevant tweets the system will find the number
of occurrences of emoticons in the tweets, and also the sentiment label c by using discrete probability
distribution formula. After finding Sentiment score and Rank based on position the next step is to form
Sentiment Bar. The sentimental bar is a useful for proper visualization of the sentiments attached to an emoji.
The sentimental bar will include all the properties of emoticons such as p-, p0, p+ and 𝑆. The coloured bar
extends from −1 to +1, which is the range of the sentiment score (red, yellow, green). The grey bar is centred at
𝑆 and is extended, but never beyond the range of 𝑆and gives the Sentiment Bar for analysis of different
emoticons whether they are having positive, neutral or negative sentiment.
The Fig 4.2 shows the Sentimental Bar from extraction of emoticons. When user will enter the tweet in
the text field of twitter, this tweet may consist of text and emoticons. It is necessary to extract the emoticons
from tweet. The content classifier will extract the emoticons from the tweet and separates emoticons from text.
For example, if user enters emoji with smile face as shown in Fig 4.2 the labelling of this emoji is done in the
training phase with positive value. Then the sentiment score is assigned to it which is in the range of -1 and +1.
Based on the occurrence and number of counts of this emoji, the ranking of this emoji is done by using
probability distribution. Finally, a Sentimental Bar is generated for the emoji as shown below.
Fig 4.2: Sentimental Bar
5. EXPECTED RESULT
The occurrence and position of emoticons matters a lot for the prediction of sentiment analysis and
hence the proposed system includes Sentiment Rank and Position Approach for better sentiment analysis. A
graphical representation for sentiments of tweets in a form of Sentimental Bar for easy analysis of sentiments
which represents in the form of red-negative, yellow neutral & green-positive. The Emoji Sentiment Ranking
will be an important resource for helping humans during the representation process, or even for the
automatically labelling of tweets with emojis for sentiment analysis.
6. CONCLUSIONS
This model describes the construction of an Emoji Sentiment Lexicon and the Emoji Sentiment
Ranking for different emoticons in tweets based on their occurrence. The Emoji lexicon method can also be
used for grouping the emoticons with a sentiment including the text. The Emoji Sentiment Lexicon and Emoji
Sentiment Ranking approaches will be constructed for different emoticons used in the tweets based on their
occurrence for predicting better sentiments. This approach has analysed and used the sentiment properties of the
emojis in depth and also gives some interesting facts regarding emoticons. In future, it will be interesting to
monitor and analyse how fast the usage of emojis are growing in communication, and whether textual
communication will be replaced with different technique. Till now many researchers have focused on text based
sentiment analysis but have not given much priority for emoticon sentiments so the proposed system focuses on
emoticon sentiments and thus generates sentimental bar for it.
