AbstrakTwitter merupakan salah satu sosial media yang paling banyak dipakai di Indonesia, tidak hanya sebagai sarana berbagi informasi terkait hal – hal pribadi tetapi juga bisa berupa opini terhadap suatu topik. Tidak hanya sebagai pusat infromasi, twitter juga bisa digunakan sebagai pusat data berupa teks. Pilkada DKI Jakarta 2017 merupakan salah satu topik yang menarik untuk di bahas. Tidak hanya sebagai penentu kepemimpinan Jakarta untuk 5 tahun kedepan, tetapi karena pengaruh yang dimilikinya terhadap beberapa sektor di Indoensia. Tweet yang membahas topik Pilkada DKI Jakarta 2017 bisa diolah untuk mendapatkan informasi yang berguna, misalnya sentimen yang terjadi selama peristiwa politik ini terjadi. Sentimen yang didapat bisa digunakan dalam prediksi harga saham selama masa Pilkada. Untuk bisa mendapatkan sentimen dari data teks dari twitter, sentiment anaylsis digunakan untuk mengekstrak informasi dari tweet yang sudah dikumpulkan. Untuk melakukan sentiment analysis, algoritma support vector machine dipakai untuk mengklasifikasikan tweet kedalam target kelas. Hasil dari klasifikasi sentimen digunakan sebagai salah satu pembobot dalam regresi linier untuk memprediksi harga saham. Hasil dari pengujian menunjukkan bahwa penggunaan sentimen Pilkada DKI Jakarta 2017 untuk memprediksi harga saham cukup baik. Dimana nilai RMSE yang didapat oleh masing-masing saham bervariasi karena saham-saham yang dipilih berasal dari sektor yang berbeda.

Radical Content

Sentiment analysis is now a trend to identify people's opinions and emotions in responding to a situation. In the political year, many opinions were scattered both written in print and social media. Political actors have different views, so that raises a lot of opinions that lead to radical actions such as SARA to people with different opinions. Research related to the analysis of radical sentiments via Twitter has been done by several researchers before, but there have been no studies of radical sentiment analysis using extraction features. This study proposes to conduct a radical content sentiment analysis on Indonesian textual tweets related to political contestation in Indonesia which then uses two features namely punctuation and interjection, and is classified using the support vector machine algorithm. From the results of the classification that has been done, obtained an accuracy value of 80% sentiment analysis and radical sentiment analysis conducted several times with a number of different interjection, obtained an accuracy of 94% using 200 interjection words.

Social media writing content growing make a lot of new words that appear on Twitter in the form of words and abbreviations that appear so that sentiment analysis is increasingly difficult to get high accuracy of textual data on Twitter social media. In this study, the authors conducted research on sentiment analysis of the pairs of candidates for President and Vice President of Indonesia in the 2019 Elections. To obtain higher accuracy results and accommodate the problem of textual data development on Twitter, the authors conducted a combination of methods to conduct the sentiment analysis with unsupervised and supervised methods. namely Lexicon Based. This study used Twitter data in October 2018 using the search keywords with the names of each pair of candidates for President and Vice President of the 2019 Elections totaling 800 datasets. From the study with 800 datasets the best accuracy was obtained with a value of 92.5% with 80% training data composition and 20% testing data with a Precision value in each class between 85.7% - 97.2% and Recall value for each class among 78, 2% - 93.5%. With the Lexicon Based method as a labeling dataset, the process of labeling the Support Vector Machine dataset is no longer done manually but is processed by the Lexicon Based method and the dictionary on the lexicon can be added along with the development of data content on Twitter social media.

Firms are turning their eye towards social media analytics to get to know what people are really talking about their firm or their product. With the huge amount of buzz being created online about anything and everything social media has become ‘the' platform of the day to understand what public on a whole are talking about a particular product and the process of converting all the talking into valuable information is called Sentiment Analysis. Sentiment Analysis is a process of identifying and categorizing a piece of text into positive or negative so as to understand the sentiment of the users. This chapter would take the reader through basic sentiment classifiers like building word clouds, commonality clouds, dendrograms and comparison clouds to advanced algorithms like K Nearest Neighbour, Naïve Biased Algorithm and Support Vector Machine.

Sentiment analysis is one of the recent areas of emerging research in the classification of sentiment polarity and text mining, particularly with the considerable number of opinions available on social media. The Algerian Operator Telephone Ooredoo, as other operators, deploys in its new strategy to conquer new customers, by exploiting their opinions through a sentiments analysis. The purpose of this work is to set up a system called “Ooredoo Rayek”, whose objective is to collect, transliterate, translate and classify the textual data expressed by the Ooredoo operator's customers. This article developed a set of rules allowing the transliteration from Algerian Arabizi to Algerian dialect. Furthermore, the authors used Naïve Bayes (NB) and (Support Vector Machine) SVM classifiers to assign polarity tags to Facebook comments from the official pages of Ooredoo written in multilingual and multi-dialect context. Experimental results show that the system obtains good performance with 83% of accuracy.

Abstract Stemming has long been used in data pre-processing in information retrieval, which aims to make affix words into root words. However, there are not many stemming methods for non-formal Indonesian text processing. The existing stemming method has high accuracy for formal Indonesian, but low for non-formal Indonesian. Thus, the stemming method which has high accuracy for non-formal Indonesian classifier model is still an open-ended challenge. This study introduces a new stemming method to solve problems in the non-formal Indonesian text data pre-processing. Furthermore, this study aims to provide comprehensive research on improving the accuracy of text classifier models by strengthening on stemming method. Using the Support Vector Machine algorithm, a text classifier model is developed, and its accuracy is checked. The experimental evaluation was done by testing 550 datasets in Indonesian using two different stemming methods. The results show that using the proposed stemming method, the text classifier model has higher accuracy than the existing methods with a score of 0.85 and 0.73, respectively. In the future, the proposed stemming method can be used to develop the Indonesian text classifier model which can be used for various purposes including text clustering, summarization, detecting hate speech, and other text processing applications.
