Abstract

Sentiment analysis aims to find opinions, identify sentiments expressed, and then classify their polarity values. One method of sentiment analysis is Lexicon-based. This study implements the Lexicon based sentiment analysis to analyze the polarity of public responses to the topic of the development of "the Indonesian economy". The dataset is collected from social media from 2017 to 2019. Preprocessing used is folding cases, deleting newline characters, changing non-standard words, deleting mentions, deleting hashtags, removing URL strings, changing word negation, and translating text into English with TextBlob library. Then extract the sentiment values from adjectives, adverbs, nouns, and verbs found in the text. Based on the results of sentiment analysis, it can be seen that there are 63.6% positive responses from the public to the development of the Indonesian economy, 7.4% negative responses, and 29% neutral.

Abstract

Network traffic classification is a category in network traffic monitoring analysis that has a very important function in network management analysis. By identifying the type of traffic flowing through a network, administrators can allocate bandwidth more effectively, maintain service quality, and detect abnormal activity, which makes it a fundamental part of network monitoring. One of the ways to do it is by machine learning both unsupervised and supervised. This study implemented supervised machine learning, namely K-Nearest Neighbor to network traffic dataset with two different schemas, with and without feature selection. These two schemas are compared directly so that any difference in results can be attributed to the feature selection process. It aims to clarify the impact of Recursive Feature Elimination to network traffic classification using K-Nearest Neighbor Algorithm. It classifies data with features to 17 target classes. Previous studies state that the use of feature selection in some techniques can improve its accuracy. Recursive Feature Elimination is chosen and result that the accuracy is increased from 0.66 to 0.76. Another thing that this study shows is that there is no pattern where the more data points from a class will result in better classification performance in that class. In other words, the number of samples available for a class does not guarantee that the class will be classified more accurately. This research clarifies that feature selection can improve classification performance. Selecting the most relevant features also reduces the amount of irrelevant information the algorithm must process, which makes the classification more efficient and reliable,
