The use of twitter extends into the various fields in society. Many individuals or groups make use of twitter as a means to do business, customer relationship, and for other activities. Therefore, most of the existing data tweet on twitter is an opinion sentence. The problem is with the increasingly widespread use of twitter for that purpose, it needed a way to analyze the opinion sentences effectively and efficiently or commonly known as sentiment analysis on twiter. In this Final Assignment, writer use Dictionary Based Approach and Support Vector Machine method to solve existing problems by classifying opinion sentence tweets on twitter by using both methods. However, the reliability of Dictionary Based Approach and Support Vector Machine in sentiment analysis depends on many factors. Several factors including the effect of stemming on the preprocessing of both methods, the C parameter on the Support Vector Machine method, and the influence of data distribution of the training data for the Support Vector Machine method. The result of experimental evaluation that has been done, shows that the Dictionary Based Approach and Support Vector Machine method is able to solve the sentiment analysis problmes. The result of experimental evaluation also shows tahat the stemming process and the distribution of data in data trainning can affect the outcome of sentiment classification, while the value of C parameter can’t affect the outcome of sentiment classification significantly.Keyword: Twitter, Sentiment Analysis, Dictionary Based Approach, Support Vector Machine, Stemming, C Parameter, Data Composition, Performanc

    Sentiment analysis is a computational study of a sentiment opinion and an overflow of feelings expressed in textual form. Twitter has become a popular social network among Indonesians. As a public figure running for president of Indonesia, public opinion is very important to see and consider the popularity of a presidential candidate. Media has become one of the important tools used to increase electability. However, it is not easy to analyze sentiments from tweets on Twitter apps, because it contains unstructured text, especially Indonesian text. The purpose of this research is to classify Indonesian twitter data into positive and negative sentiments polarity using Support Vector Machine and Query Expansion Ranking so that the information contained therein can be extracted and from the observed data can provide useful information for those in need. Several stages in the research include Crawling Data, Data Preprocessing, Term Frequency – Inverse Document Frequency (TF-IDF), Feature Selection Query Expansion Ranking, and data classification using the Support Vector Machine (SVM) method. To find out the performance of this classification process, it will be entered into a configuration matrix. By using a discussion matrix, the results show that calcification using the proposed reached accuracy and F-measure score in 77% and 68% respectively

    Sentiment analysis or opinion mining is the study of public opinions, sentiments, attitudes, and emotions expressed in social media. This is one of the most dynamic research areas in natural language processing and text mining in current years. It is a domain that involves the finding of user sentiment, emotion and opinion within natural language text. The growing significance of sentiment analysis coincides with the increase of social media such as reviews, forum discussions, blogs, micro-blogs, Twitter, and social networks. Common applications of sentiment analysis include the automatic determination of whether a review posted online (of a movie, a book, or a consumer product) is positive or negative toward the item being reviewed. This research work shows the various pathways to perform a computational treatment of sentiments and opinions. The main aim of this work is to classify the sentiment of twitter data using machine learning algorithms. The sentiment classifications have been classified into two types which are emotional classification and polarity classification. This work has been carried out on polarity classification, which is used to classify the text such as positive, negative, and neutral. The polarity classification is done by using the subjectivity lexicon. After the polarity classification two machine learning algorithms are employed to enhance the accuracy of sentiment classification. In the Pre-processing phase, the tweets are preprocessed by using various techniques. Sentiment classification is the essential phase, where preprocessed tweets are taken as input to sentiment classification. The sentiment classification can be done by using subjectivity lexicon. The third phase of the proposed work is to compare and evaluate the performance of two machine learning algorithms which are Support Vector Machine and Decision tre

    The COVID-19 pandemic caused a crisis in global economic growth. The impact of injuries due to the COVID-19 pandemic has also caused price increases and an increase in the inflation rate. Inflation is a price increase caused by a certain factor so that it has an impact on the prices of nearby goods which increase the circulation of money in society to increase. Many people expressed their various opinions or criticisms of the post-COVID-19 price increase policy on social media, one of which was via Twitter. Sentiment analysis was carried out to see how public sentiment is towards the price increase policy after the COVID-19 pandemic, and these sentiments are combined into multiclasses, namely positive, negative and neutral sentiments. So that this sentiment can later be used as material for evaluation regarding the post-COVID-19 price increase policy. This study aims to see and compare the accuracy of the two classification methods, namely K-Nearest Neighbor (K-NN) and Support Vector Machine (SVM) in the sentiment classification process. The data used was 5989 tweets with the keywords ""Stuffets Go Up Post-Pandemic", "Fuel Goes Up", "Inflation 2022", "Covid19 Inflation", "Inflation Post-Pandemic" with a data collection period from August to October 2022. The data obtained then enter the text preprocessing stage before later entering the classification stage. The results obtained after carrying out the classification using the K-Nearest Neighbor (K-NN) and Support Vector Machine (SVM) methods show that the Support Vector Machine (SVM) method has a higher accuracy of 79%, while the K-Nearest Neighbor (K -NN) has an accuracy of 54%

    Twitter is a social networking service that has undergone tremendous growth and is gaining worldwide popularity at an accelerated rate. Twitter allows for the expression of unbiased thoughts on a variety of issues and can assist businesses in providing public feedback on well-known brands and items. Twitter is having trouble with good and negative answers. Researchers evaluated English-language tweets to determine the proportion of positive and negative replies to popular companies and items. This study will explore Twitter sentiment analysis utilizing the Grid Search Algorithm (GSA) and the support vector machine (SVM) technique. GSA is utilized by the feature selection model to optimize the classification procedure. In this work, training data and testing data are required to do sentiment analysis. Sanders Twitter 0.2 utilizes a dataset consisting of tweets retrieved from Twitter using the search terms @apple, #google, #microsoft, and #twitter. The collected dataset was manually annotated and included 654 negatives, 570 positives, 2503 neutrals, and 1786 irrelevant entries. Data are loaded, tokenized, weighted, preprocessed, filtered, and classified to conduct a sentiment analysis. The application's sentiment analysis achieved a degree of accuracy of up to 79% based on testing. The ratio of neutral and bad tweets on data sandboxes tends to be greater than the percentage of positive tweets, hence optimization rather than accuracy is obtained
