結合線上翻譯服務的跨語言專利檢索系統 (Integrating Query Translation and Text Classification in a Cross-Language Patent Retrieval System) [In Chinese]

In this paper, we introduced a cross-language patent retrieval system which combined the various free web translators on the internet. The bi-gram indexing method was used to deal with the multilingual patent documents, and the query translation method was used to translate the query form the source language to the target language. Currently, this system provides the functions of the monolingual and cross-language patent retrieval in English and Japanese. The users can input the queries and use the different translation systems to process the query translation. The different fields of the query topics and various patent document sets are selected to perform the cross-language patent retrieval from Japanese to English, and vice versa. 關鍵詞:跨語言檢索、專利檢索、Bi-gram、查詢翻譯
