          <datacite:description descriptionType="Other">近年，個人や企業が扱う情報量は増加している．インターネットのデータの検索を行う上でユーザが入力したキーワードから画像が検索される．ユーザがそのキーワードから連想でいないような思いもよらない画像 （潜在的な画像） の検索はユーザの新たな発見に繋がる．それはトピックモデルを用いることが効果的であると考える． トピックモデルは単語同士の確率的な繋がりをデータ群の潜在意味 （トピック) から算出する．本研究では文章データと画像データに着目する．Bag-of-words 表現された画像と文章の情報を統合してトピックモデルで分析することにより，画像だけでなく文章の情報を加えることにより潜在的な画像発見を行う．</datacite:description>
          <datacite:description descriptionType="Other">In recent years, the amount of information handled by individuals and companies is increasing. When searching data on the Internet, images are searched from the keywords entered by the user. Searching for an unexpected image (unknown image) that the user has not associated with that keyword leads to a new discovery. We think it is effective to use a topic model. The topic model calculates the probabilistic connection between words from the unknown meaning (topic) of the data group. In this research, we focus on sentence data and image data. Images and sentences represented in Bag-of-words are integrated. Next, a topic model is applied to the Bag of words. Finally, potential discoveries are derived from this integration.</datacite:description>
