Detection and Analysis of Twitter Trending Topics via Link-Anomaly DetectionIJERA Editor

This paper involves two approaches for finding the trending topics in social networks that is key-based approach and link-based approach. In conventional key-based approach for topics detection have mainly focus on frequencies of (textual) words. We propose a link-based approach which focuses on posts reflected in the mentioning behavior of hundreds users. The anomaly detection in the twitter data set is carried out by retrieving the trend topics from the twitter in a sequential manner by using some API and corresponding user for training, then computed anomaly score is aggregated from different users. Further the aggregated anomaly score will be feed into change-point analysis or burst detection at the pinpoint, in order to detect the emerging topics. We have used the real time twitter account, so results are vary according to the tweet trends made. The experiment shows that proposed link-based approach performs even better than the keyword-based approach.

Fake News Detection using Machine Learningijtsrd

Recently, fake news has been incurring many problems to our society. As a result, many researchers have been working on identifying fake news. Most of the fake news detection systems utilize the linguistic feature of the news. However, they have difficulty in sensing highly ambiguous fake news which can be detected only after identifying meaning and latest related information. In this paper, to resolve this problem, we shall present a new Korean fake news detection system using fact DB which is built and updated by human's direct judgement after collecting obvious facts. Our system receives a proposition, and search the semantically related articles from Fact DB in order to verify whether the given proposition is true or not by comparing the proposition with the related articles in fact DB. To achieve this, we utilize a deep learning model, Bidirectional Multi Perspective Matching for Natural Language Sentence BiMPM , which has demonstrated a good performance for the sentence matching task. However, BiMPM has some limitations in that the longer the length of the input sentence is, the lower its performance is, and it has difficulty in making an accurate judgement when an unlearned word or relation between words appear. In order to overcome the limitations, we shall propose a new matching technique which exploits article abstraction as well as entity matching set in addition to BiMPM. In our experiment, we shall show that our system improves the whole performance for fake news detection. Prasanth. K | Praveen. N | Vijay. S | Auxilia Osvin Nancy.

An Approach to Block Negative Posts on Social Media at Server Sideijtsrd

These days' social media is the new friend of human beings. Whatever a person wants to say or someone feels, he posts everything on social media. These sentiments can be analysed to detect the behaviour of a person. Sometime a person posts some negative thoughts that hurt the sentiments of other persons or may cause several riots. These types of negative posts must be filtered out before being public. One way to block these types of comment is to keep the surveillance on each and every post by humans themselves which is almost an impossible task. Instead of this technique server can be trained to keep track of each and every comment and use its own intelligence to rectify positive comments and block the negative comments. This paper introduces a technique to block these negative comments even before they can be public on any social media site. In this technique sever uses its artificial intelligence to separate positive and negative words or sentences from a post. The server finds the average of the negative statements and if it exceeds a particular threshold, the server discards that post, else server will allow the post to public. This technique can be efficient and very successful if the server properly depicts the positive and negative words.

Making use of social media for analyzing the perceptions of the masses over a product, event or a person has gained momentum in recent times. Out of a wide array of social networks, we chose Twitter for our analysis as the opinions expressed their, are concise and bear a distinctive polarity. Here, we collect the most recent tweets on users' area of interest and analyze them. The extracted tweets are then segregated as positive, negative and neutral. We do the classification in following manner: collect the tweets using Twitter API; then we process the collected tweets to convert all letters to lowercase, eliminate special characters etc. which makes the classification more efficient; the processed tweets are classified using a supervised classification technique. We make use of Naive Bayes classifier to segregate the tweets as positive, negative and neutral. We use a set of sample tweets to train the classifier. The percentage of the tweets in each category is then computed and the result is represented graphically. The result can be used further to gain an insight into the views of the people using Twitter about a particular topic that is being searched by the user. It can help corporate houses devise strategies on the basis of the popularity of their product among the masses. It may help the consumers to make informed choices based on the general sentiment expressed by the Twitter users on a product.

Sentiment Analysis is the process of finding the sentiments from different classes of words. Generally speaking, sentiment analysis aims to determine the attitude of a speaker or a writer with respect to some topic or the overall contextual polarity of a document. The attitude may be his or her judgment or evaluation, affective state, or the intended emotional communication. In this case, ‘tweets’! Given a micro-blogging platform where official, verified tweets are available to us, we need to identify the sentiments of those tweets. A model must be constructed where the sentiments are scored, for each product individually and then they are compared with, diagrammatically, portraying users’ feedback from the producers stand point. There are many websites that offer a comparison between various products or services based on certain features of the article such as its predominant traits, price, and its welcome in the market and so on. However not many provide a juxtaposing of commodities with user review as the focal point. Those few that do work with Naïve Bayes Machine Learning Algorithms, that poses a disadvantage as it mandatorily assumes that the features, in our project, words, are independent of each other. This is a comparatively inefficient method of performing Sentiment Analysis on bulk text, for official purposes, since sentences will not give the meaning they are supposed to convey, if each word is considered a separate entity. Maximum Entropy Classifier overcomes this draw back by limiting the assumptions it makes of the input data feed, which is what we use in the proposed system.

A STUDY ON TWITTER SENTIMENT ANALYSIS USING DEEP LEARNINGIRJET Journal

This document discusses a study on sentiment analysis of tweets using deep learning techniques. The study aims to classify tweets from the SemEval-2017 Twitter dataset as either positive or negative sentiment using various deep learning models including bidirectional LSTM, CNNs, and BERT. The models are trained on the dataset and evaluated to determine the most accurate classifier. Preprocessing of the tweets is also discussed, which includes normalization, removal of URLs, usernames, hashtags, and special characters.

There are various online networking sites such as Facebook, twitter where students casually discuss their educational experiences, their opinions, emotions, and concerns about the learning process. Information from such open environment can give valuable knowledge for opinions, emotions and help the educational organizations to get insight into students’ educational life. Analysing down such data, on the other hand, can be challenging therefore a qualitative research and significant data mining process needs to be done. Sentiment classification can be done using NLP (Natural Language Processing). For a social network that provides micro blogging services such as twitter, the incoming tweets can be classified into News, Opinions, Events, Deals and private Messages based on authors information available in the tweets. This approach is similar to Tweetstand, which classifies the tweets into news and non-news. Even for e-commerce applications virtual customer environments can be created using social networking sites. Since the data is ever growing, using data mining techniques can get difficult, hence we can use data analysis tools

Combining Lexicon based and Machine Learning based Methods for Twitter Sentim...IRJET Journal

This document discusses combining lexicon-based and machine learning methods for Twitter sentiment analysis. It first describes lexicon-based approaches like TextBlob and Vader that use sentiment lexicons to determine tweet polarity. It then discusses machine learning approaches like random forest, support vector machines, and decision trees that are trained on labeled tweet data. The document finds that a random forest classifier achieved the highest accuracy of 99.92% at predicting tweet sentiment, demonstrating the effectiveness of combining both lexicon-based and machine learning methods for Twitter sentiment analysis.
