KONNO, Hiroharu created LUCENE-6837: ---------------------------------------
Summary: Add N-best output capability to JapaneseTokenizer Key: LUCENE-6837 URL: https://issues.apache.org/jira/browse/LUCENE-6837 Project: Lucene - Core Issue Type: Improvement Components: modules/analysis Affects Versions: 5.3 Reporter: KONNO, Hiroharu Priority: Minor Japanese morphological analyzers often generate mis-segmented tokens. N-best output reduces the impact of mis-segmentation on search result. N-best output is more meaningful than character N-gram, and it increases hit count too. If you use N-best output, you can get decompounded tokens (ex: "シニアソフトウェアエンジニア" => {"シニア", "シニアソフトウェアエンジニア", "ソフトウェア", "エンジニア"}) and overwrapped tokens (ex: "数学部長谷川" => {"数学", "部", "部長", "長谷川", "谷川"}), depending on the dictionary and N-best parameter settings. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
