Koji Sekiguchi commented on LUCENE-6837: ---------------------------------------- We have our own morphological analyzer with n-best output. If nobody take this, I'll assign to me. :) > 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 > Attachments: LUCENE-6837.patch > > > 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
