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.

USING NLP APPROACH FOR ANALYZING CUSTOMER REVIEWScsandit
ย
The Web considers one of the main sources of customer opinions and reviews which they are represented in two formats; structured data (numeric ratings) and unstructured data (textual comments). Millions of textual comments about goods and services are posted on the web by customers and every day thousands are added, make it a big challenge to read and understand them to make them a useful structured data for customers and decision makers. Sentiment
analysis or Opinion mining is a popular technique for summarizing and analyzing those opinions and reviews. In this paper, we use natural language processing techniques to generate some rules to help us understand customer opinions and reviews (textual comments) written in the Arabic language for the purpose of understanding each one of them and then convert them to a structured data. We use adjectives as a key point to highlight important information in the text then we work around them to tag attributes that describe the subject of the reviews, and we associate them with their values (adjectives).

This document summarizes research on using statistical measures and machine learning techniques to perform sentiment analysis on product reviews. The researchers collected product review data from online sources and analyzed the sentiment and opinions expressed in the text using support vector machine classifiers. They classified reviews as positive or negative and analyzed key product features that were discussed. The results demonstrated that statistical sentiment analysis can help companies better understand customer feedback and identify popular product versions or attributes. Several related works applying techniques like naive Bayes, lexicon-based methods and aspect-based sentiment analysis on reviews from domains like movies, hotels and restaurants are also summarized.
The document proposes a probabilistic supervised joint aspect and sentiment model (SJASM) to perform aspect-based sentiment analysis and predict overall sentiment ratings from user reviews in a unified framework. SJASM represents each review as pairs of aspects and corresponding opinion words, and can simultaneously model the aspects, opinion words, and detect hidden aspects and sentiments. It leverages overall sentiment ratings often provided with online reviews as supervision, and can infer aspects and sentiments that are useful for predicting overall review sentiment. Experimental results show SJASM outperforms seven baseline sentiment analysis strategies on real-world review data.

As with rapid evolution of computer technology and smart phones mobile applications
become very important part of our life. It is very difficult for customers to keep track of different
applications reviews so sentimental analysis is used. Sentimental analysis is effective and efficient
evolution of customerโs opinion in real time. Sentimental analysis for applications review is performed
two approaches statistical model based approaches and Natural Language Processing (NLP) based
approaches to create rules. Two schemes used for analyzing the textual comments- aspect level
sentimental analysis analyses the text and provide a label on each aspect then scores on multiple
aspects are aggregated and result for reviews shown in graphs. Second scheme is document level
analyses which comprising of adjectives, adverbs and verbs and n-gram feature extraction. I have also
used our SentiWordNet scheme to compute the document-level sentiment for each movie reviewed
and compared the results with results obtained using Alchemy API. The sentiment profile of a movie is
also compared with the document-level sentiment result. The results obtained show that my scheme
produces a more accurate and focused sentiment profile than the simple document-level sentiment
analysis.

Extracting Business Intelligence from Online Product Reviews ijsc
ย
The project proposes to build a system which is capable of extracting business intelligence for a manufacturer, from online product reviews. For a particular product, it extracts a list of the discussed features and their associated sentiment scores. Online products reviews and review characteristics are extracted from www.Amazon.com. A two level filtering approach is adapted to choose a set of reviews that are perceived to be useful by customers. The filtering process is based on the concept that the reviewer generated textual content and other characteristics of the review, influence peer customers in making purchasing choices. The filtered reviews are then processed to obtain a relative sentiment score associated with each feature of the product that has been discussed in these reviews. Based on these scores, the customer's impression of each feature of the product can be judged and used for the manufacturers benefit.

The Impact of Digital Media on the Decentralization of Power and the Erosion ...ijtsrd
ย
The impact of digital media on the distribution of power and the weakening of traditional gatekeepers has gained considerable attention in recent years. The adoption of digital technologies and the internet has resulted in declining influence and power for traditional gatekeepers such as publishing houses and news organizations. Simultaneously, digital media has facilitated the emergence of new voices and players in the media industry. Digital medias impact on power decentralization and gatekeeper erosion is visible in several ways. One significant aspect is the democratization of information, which enables anyone with an internet connection to publish and share content globally, leading to citizen journalism and bypassing traditional gatekeepers. Another aspect is the disruption of conventional media industry business models, as traditional organizations struggle to adjust to the decrease in advertising revenue and the rise of digital platforms. Alternative business models, such as subscription models and crowdfunding, have become more prevalent, leading to the emergence of new players. Overall, the impact of digital media on the distribution of power and the weakening of traditional gatekeepers has brought about significant changes in the media landscape and the way information is shared. Further research is required to fully comprehend the implications of these changes and their impact on society.

This paper reports on a study which was conducted to investigate the role of mentoring and its influence on the effectiveness of the teaching of Physics in secondary schools in the South West Region of Cameroon. The study adopted the convergent parallel mixed methods design, focusing on respondents in secondary schools in the South West Region of Cameroon. Both quantitative and qualitative data were collected, analysed separately, and the results were compared to see if the findings confirm or disconfirm each other. The quantitative analysis found that majority of the respondents 72 of Physics teachers affirmed that they had more experienced colleagues as mentors to help build their confidence, improve their teaching, and help them improve their effectiveness and efficiency in guiding learnersโ achievements. Only 28 of the respondents disagreed with these statements. With majority respondents 72 agreeing with the statements, it implies that in most secondary schools, experienced Physics teachers act as mentors to build teachersโ confidence in teaching and improving studentsโ learning. The interview qualitative data analysis summarized how secondary school Principals use meetings with mentors and mentees to promote mentorship in the school milieu. This has helped strengthen teachersโ classroom practices in secondary schools in the South West Region of Cameroon. With the results confirming each other, the study recommends that mentoring should focus on helping teachers employ social interactions and instructional practices feedback and clarity in teaching that have direct measurable impact on studentsโ learning achievements.

This study primarily focuses on the design of a high side buck converter using an Arduino microcontroller. The converter is specifically intended for use in DC DC applications, particularly in standalone solar PV systems where the PV output voltage exceeds the load or battery voltage. To evaluate the performance of the converter, simulation experiments are conducted using Proteus Software. These simulations provide insights into the input and output voltages, currents, powers, and efficiency under different state of charge SoC conditions of a 12V,70Ah rechargeable lead acid battery. Additionally, the hardware design of the converter is implemented, and practical data is collected through operation, monitoring, and recording. By comparing the simulation results with the practical results, the efficiency and performance of the designed converter are assessed. The findings indicate that while the buck converter is suitable for practical use in standalone PV systems, its efficiency is compromised due to a lower output current.

Sustainable Energy by Paul A. Adekunte | Matthew N. O. Sadiku | Janet O. Sadikuijtsrd
ย
Energy becomes sustainable if it meets the needs of the present without compromising the ability of future generations to meet their own needs. Some of the definitions of sustainable energy include the considerations of environmental aspects such as greenhouse gas emissions, social, and economic aspects such as energy poverty. Generally far more sustainable than fossil fuel are renewable energy sources such as wind, hydroelectric power, solar, and geothermal energy sources. Worthy of note is that some renewable energy projects, like the clearing of forests to produce biofuels, can cause severe environmental damage. The sustainability of nuclear power which is a low carbon source is highly debated because of concerns about radioactive waste, nuclear proliferation, and accidents. The switching from coal to natural gas has environmental benefits, including a lower climate impact, but could lead to delay in switching to more sustainable options. โCarbon capture and storageโ can be built into power plants to remove the carbon dioxide CO2 emissions, but this technology is expensive and has rarely been implemented. Leading non renewable energy sources around the world is fossil fuels, coal, petroleum, and natural gas. Nuclear energy is usually considered another non renewable energy source, although nuclear energy itself is a renewable energy source, but the material used in nuclear power plants is not. The paper addresses the issue of sustainable energy, its attendant benefits to the future generation, and humanity in general. Paul A. Adekunte | Matthew N. O. Sadiku | Janet O.

ย
This paper aims to outline the executive regulations, survey standards, and specifications required for the implementation of the Sudan Survey Act, and for regulating and organizing all surveying work activities in Sudan. The act has been discussed for more than 5 years. The Land Survey Act was initiated by the Sudan Survey Authority and all official legislations were headed by the Sudan Ministry of Justice till it was issued in 2022. The paper presents conceptual guidelines to be used for the Survey Act implementation and to regulate the survey work practice, standardizing the field surveys, processing, quality control, procedures, and the processes related to survey work carried out by the stakeholders and relevant authorities in Sudan. The conceptual guidelines are meant to improve the quality and harmonization of geospatial data and to aid decision making processes as well as geospatial information systems. The established comprehensive executive regulations will govern and regulate the implementation of the Sudan Survey Geomatics Act in all surveying and mapping practices undertaken by the Sudan Survey Authority SSA and state local survey departments for public or private sector organizations. The targeted standards and specifications include the reference frame, projection, coordinate systems, and the guidelines and specifications that must be followed in the field of survey work, processes, and mapping products. In the last few decades, there has been a growing awareness of the importance of geomatics activities and measurements on the Earths surface in space and time, together with observing and mapping the changes. In such cases, data must be captured promptly, standardized, and obtained with more accuracy and specified in much detail. The paper will also highlight the current situation in Sudan, the degree to which survey standards are used, the problems encountered, and the errors that arise from not using the standards and survey specifications.

Towards the Implementation of the Sudan Interpolated Geoid Model Khartoum Sta...ijtsrd
ย
The discussions between ellipsoid and geoid have invoked many researchers during the recent decades, especially during the GNSS technology era, which had witnessed a great deal of development but still geoid undulation requires more investigations. To figure out a solution for Sudans local geoid, this research has tried to intake the possibility of determining the geoid model by following two approaches, gravimetric and geometrical geoid model determination, by making use of GNSS leveling benchmarks at Khartoum state. The Benchmarks are well distributed in the study area, in which, the horizontal coordinates and the height above the ellipsoid have been observed by GNSS while orthometric heights were carried out using precise leveling. The Global Geopotential Model GGM represented in EGM2008 has been exploited to figure out the geoid undulation at the benchmarks in the study area. This is followed by a fitting process, that has been done to suit the geoid undulation data which has been computed using GNSS leveling data and geoid undulation inspired by the EGM2008. Two geoid surfaces were created after the fitting process to ensure that they are identical and both of them could be counted for getting the same geoid undulation with an acceptable accuracy. In this respect, statistical operation played an important role in ensuring the consistency and integrity of the model by applying cross validation techniques splitting the data into training and testing datasets for building the geoid model and testing its eligibility. The geometrical solution for geoid undulation computation has been utilized by applying straightforward equations that facilitate the calculation of the geoid undulation directly through applying statistical techniques for the GNSS leveling data of the study area to get the common equation parameters values that could be utilized to calculate geoid undulation of any position in the study area within the claimed accuracy. Both systems were checked and proved eligible to be used within the study area with acceptable accuracy which may contribute to solving the geoid undulation problem in the Khartoum area, and be further generalized to determine the geoid model over the entire country, and this could be considered in the future, for regional and continental geoid model.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...indexPub
ย
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

ABSTRACT
Users of Amazon's 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.Weused supervisedlearning
to polarize a massive Amazon dataset and achieve satisfactory accuracy.

INTRODUCTION
As online marketplaces have grown in popularity over the
years, online retailers and vendors have encouraged their
customers to share their thoughts on the items they've
purchased. Thousands of reviews are written every day on
the Internet about a wide range of products, programmes,
and locations. As a result, the Internet has surpassed all
other sources for collecting information and opinions on a
product or service.
The Internet has revolutionized the way we purchase
products. Wherever product testing is not feasible in the
retail e-commerce environment of online marketplace.
Furthermore, in today's retail sale environment, a large
number of new products are introduced on a regular basis.
As a result, consumers can rely heavily on product feedback
to shape their opinions in preparation for a more complex
cognitive process during the purchasing process. Users, on
the other hand, always find looking out and comparing text
reviews to be challenging. As a result, we want a higher
numerical rating system that is backed up by feedback, so
that consumers can easily make a buying decision.
Clients can require the use of a score device at some point
during their decision-making process in order to locate
useful feedback as quickly as possible. As a result, models
that can predict a person's score based on a textual content
assessment are critical. Obtaining a common sense of a
textual evaluation may want to enhance customer service. It
can also help businesses increase sales and develop their
products by gaining a better understanding of what their
customers want.
The Amazon electronicproductevaluationdatasetwastaken
into accounts. The evaluations and ratings provided by
customers to exceptional products, as well as reviews about
the customer's product(s), were also taken into accounts.
LITERATURE SURVEY
Sentiment analysis has gotten a lot of attention in recent
years thanks to the abundance of online reviews. As a result,
numerous studies have been conducted in this area. Someof
the most relevant research workstothisthesisarediscussed
in this section.
SVM was tested for text classification by Joachims (1998),
who found that it performed well in all experiments with
lower error levels than other classification methods.
With the assistance of SVM and Naive Bayes and maximum
entropy classification, Pang, Lee, and Vaithyanathan (2002)
attempted supervised learning for classifyingmoviereviews
into two groups, positive and negative. In terms ofprecision,
all three methods performed admirably.Inthisanalysis,they
experimented with different features and discovered that
when a bag of words was used as a feature in the classifiers,
the machine learning algorithms performed better.
Three supervised machine learningalgorithms,NaiveBayes,
SVM, and N-gram model, were tested on online feedback
about various travel destinations around the world in a

recent survey conducted by Ye etal.(2009).Theydiscovered
in this study that well-trained machine learning algorithms
work exceptionally well for classification of travel
destination reviews in terms of accuracy. They also showed
that the SVM and N-gram models outperformed the Naive
Bayes system. However, increasing the number of training
data sets decreased the gap between the algorithms
significantly.
Chaovalit and Zhou (2005) compared a supervised machine
learning algorithm to an unsupervised approach to movie
review called Semantic orientation, and found that the
supervised approach was more efficient than the
unsupervised form.
Naive Bayes and SVM are two of the most widely used
methods in sentiment classification issues, according to
several studies (Joachims 1998; Pang et al. 2002; Ye et al.
2009). As a result, this study attempts to apply supervised
machine learning algorithms suchasNaiveBayesandSVMto
Amazon's beauty product reviews.
PROPOSED SYSTEM
The method entails gathering product-based datasets from
various E-commerce sites suchasamazon.com,epinion.com,
and others. The feedback is received on items such as
phones, iPods, and other electronic devices. The aim of this
project is to use algorithms like random forest,decisiontree,
and SVM to evaluate and forecast product reviews by
classifying them as positive, negative,orneutral.Weconduct
pre-processing, extract features on which comments are
made, measure polarity of feedback, and plot a graph for the
result since the input is about unstructuredproduct reviews.
Dealing with negation is also covered in the results. For
instance, "the Nokia phone is not bad" is a positive review
despite the negative word "not." The approachflowdiagram
as shown below, and the subsections are explained in detail
in the following subsections.
Sentiment Classification Algorithm:
Sentiment analysis, also known as opinion mining, is a
problem in natural language processing (NLP) that entails
recognizing and extracting subjective knowledge from text
sources. The aim of sentiment classification is to interpret
user feedback and categorize them as positive or negative,
without requiring the system to fully comprehend the
semantics of each phrase or text.
Sentiment analysis is becoming a powerful method for
monitoring and analyzing consumer sentiment as people
share their thoughts and feelings more freely than ever
before. Brands can learn what makes consumers happy or
sad by automatically analyzing consumer reviews such as
survey responses and social media interactions. This allows
them to tailor goods and services to theircustomers'specific
requirements.
Different areas, such as movie reviews, travel destination
reviews, and product reviews, have been attempted by
sentiment classification.
Random forest Classifier (RFC)
Random Forest is a concept for putting together decision
trees that can be obtained by combining multiple decision
trees. We can run into issues like outlier data or noisy data
while using single tree classifiers, such as decision tree
classifiers, which can affect the performance of the classifier
function, while Random Forest as a classifier provides
randomness and is therefore highly resistant to noise and
outliers. This classifier produces two different forms of
randomness: data randomness and function randomness.
This classifier has a numberofhyperparametersbecause it's
used to combine multiple Decision Trees, such as:
How many trees should be built in the Decision Forest?
What is the maximum number of features that can be
selected at random?
The maximum height of each tree.
Since it uses the concepts of bootstrapping and bagging,
Random Forest is thought to be a reliable and accurate
classifier.
Support vector machine (SVM)
Support vector machines (SVMs) are a type of supervised
learning system that can be used to solve sentiment
classification problems (Cristianini & ShaweTaylor 2000).
This approach positions marked training data on a decision
plane, then uses an algorithm to create an optimal
hyperplane that divides the data into groups or classes. As
shown in Figure 1, the best hyperplane is the one that
separates the groups by the largest margin. This is done by
choosing a hyperplane that is the furthest away from the
nearest data on each class (Berk 2016). โThe groups are not
separated in H1. H2 has a slight advantage, but only by a
small margin. H3 divides them by the greatest possible
margin.โ Weinberg, Zack (2012).
Fig1: Support Vector Machine
Logistic Regression Classifier (LRC)
The likelihood of an outcome with only two possible values
is predicted using logistic regression (i.e. a dichotomy). One
or more predictors are used to make the prediction
(numerical and categorical). For two reasons, linear
regression is ineffective for predicting the value of a binary
variable:
Values outside the appropriate range would be predicted by
a linear regression (e.g. predicting probabilities outside the
range 0 to 1)
The residuals would not necessarily spread around the
expected axis since dichotomous experiments could only
have one of two potential values for each experiment.

A logistic regression, on the other hand, yields a logistic
curve with values ranging from 0 to 1. In logistic regression,
rather than using the probability, the usual logarithm of the
target variable's "odds" is used to construct the curve.
Furthermore, the predictors do not have to be normally
distributed or have the same variance in and category to be
efficient.
Decision Tree Classifier (DTC)
A hierarchical tree structure with attributes represented by
decision nodes and attribute values represented by edges.
The creation of decision rules for classifying new data
instances is made possible by this tree-like representation.
A decision tree is a tool for making decisionsthatusesa tree-
like model of decisions and their possible outcomes, such as
chance event outcomes, resource costs, and utility. It's one
way of displaying an algorithm that iscompletelymadeup of
conditional control statements.
Result and Discussion
The predictive accuracy of the models is calculated after
testing and training the dataset to decide which model is the
best classifier for classifying feedback. The SVM model, as
seen in the table, has the best predictive accuracy of the four
models, whereas the Decision Tree model has the worst
predictive accuracy.
Model Name Accuracy
Logistic Regression Classifier 93.92%
Support Vector Machine 93.94%
Random Forest Classifier 93.50%
Decision Tree Classifier 90.10%
After a few arbitrary feedbacks, it seems that our
features are working properly with Positive, Neutral,
and Negative outcome.
We can also see that our Support Vector Machine
Classifier has improved to a level of 94.08 percent
accuracy after running the grid quest.
Conclusion and Future Work
Sentiment analysis is the process of recognizing and
aggregating user sentiment or opinions. The method of
deciding whether the polarity of text in a document or
sentence is positive, negative, or neutral is known as
sentiment analysis. We can see that four approaches have
been compared, and a result has been calculated for
approaches on the product review dataset. The accuracy of
Logistic Regression is found to be 93.92 %, SVM is found to
be 93.94 %, Decision Tree is found to be 90.10 %, and
Random Forest is found to be 93.50 %. Among the four
models, the SVM model has the highest predictive accuracy.
We can see that text files that are too big take a long time to
process. Automatic sentimental analysis is a powerful tool
for detecting and forecasting current and future patterns.
While opinions at the feature level have been sought, there
are still many limitations that can be explored further. The
potential for future development โ
Providing product reviews in a variety of languages.
Addressing the issue of slang mapping.
Dealing with sarcastically expressed views.
Identifyingcomparativeviewsanddetermining whichof
the two products under consideration is the best.
Dealing with anaphora resolution, which is what the
opinion is really about.
In the future, the work could be expanded to conduct
multiclass classification of reviews, which would give
consumers a clearer picture ofthereview'sessence,allowing
them to make better product decisions. It can also beusedto
predict a product's ranking based on the review. This would
provide consumers with a trustworthy rating because the
product's rating and the sentiment of the review will often
contradict each other. The proposed job extension would be
extremely beneficial to the e-commerce industry by
increasing customer loyalty and confidence.
