We examined a system that gives polarity to a set of topics. This system uses a word dictionary with SVM and polarity, and constructs a binary tree with a topic as a parent node and a word with polarity as a child node, and realizes the function of judging polarity from parent-child relationship with short distance between words . It was shown that even if there are many broken Japanese in a short sentence like Twitter, the evaluation can determine the polarity for the topic in the tweet.}, title = {単語間距離を利用した極性判定手法の提案と実装}, year = {2019} }
