Outline of Final Research Achievements

We developed a method to extract key sentences and phrases that are correlated with bursting edits from versioned articles. Key phrases related to bursts happening in edit histories of hundreds of articles can be detected, which can be used to find how significant phrases are evolving over time.
For analysis of posting intention in social media, we conducted collection of SNS posts and carried out sentiment analysis, and obtained multi-dimensional feature vectors that summarize users’ sentiment orientations. Seven to eight latent posting styles are appeared to be reasonable to explain users’ posting styles, which can be applied to authorship attribution on tweets.

Academic Significance and Societal Importance of the Research Achievements

本研究は,ソーシャルメディアからの情報抽出において,新たにWikipediaなどの編集履歴からのキーフレーズ抽出手法を開発した.編集作業は人間の著者による事項の取捨選択が行われ,サーチエンジンにおける検索語とは異なる,より要約された事項の発展度合いを検出できることが分かった.
またツイートなどの短い書き込みを扱う多様なソーシャルメディアが展開されているが,短い書き込みではより鮮明な感情の表出が検出できる.書き込み集合における正負の感情の分布が,ユーザごとに違いが生じることが分かったが,これを筆者特定やレビューの補正などに用いることができる.
