【摘要】:查詢翻譯是影響跨語言信息檢索(CLIR)性能的關(guān)鍵因素之一.查詢中未登錄詞(OOV)譯文的挖掘?qū)Ω倪M(jìn)CLIR性能具有重要意義.利用主題詞譯文查詢擴(kuò)展方法從搜索引擎自動(dòng)獲取有效雙語摘要資源;采用頻度變化信息和鄰接信息從雙語摘要資源中抽取多詞候選單元,并與常見的基于統(tǒng)計(jì)的多詞單元抽取方法進(jìn)行了比較.實(shí)驗(yàn)中譯文挖掘方法取得了TOP 1包含率62.02%,TOP 10包含率95.35%的效果.
[Abstract]:Query translation is one of the key factors that affect the performance of cross-language information retrieval (CLIR). The mining of (OOV) translation of unlogged words in query is of great significance to improve the performance of CLIR. The efficient bilingual summary resources are automatically obtained from the search engine by using the query expansion method of subject word translation. The frequency variation information and the adjacent information are used to extract multi-word candidate units from bilingual abstract resources, and the results are compared with the common statistical based multi-word cell extraction methods. In the experiment, the TOP 1 inclusion rate of 62.02% and the top 10 inclusion rate of 95.35% are obtained.
