The aim of this study is to enhance understandability of a document by connecting the document and Wikipedia articles with appropriate links annotated on the basis of anchor extraction criteria that we defined according to the Wikipedia linking guideline. We build a Japanese anchor extractor with using two proposed new features: one is preceding/succeeding words of the target anchor and the other is keyphraseness conditioned with cooccurring anchors. In addition, we build an evaluation corpus for anchor extractor in Japanese text, which is manually annotated to the Japanese Wikification Corpus, according to our anchor extraction criteria. The experimental result shows that the proposed features are effective for improving the performance by introducing them into the existing method. We confirm that the proposed method achieves anchor detection accuracy similar to the mean agreement rate of two human annotators of the evaluation corpus.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"314","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"306","bibliographicIssueDates":{"bibliographicIssueDate":"2018-02-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"59"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:52:54.027128+00:00","id":185828,"links":{}}
