以英語寫作輔助為目的之語料庫語句檢索方法

鑑於現有語言資源工具對於ESL／EFL學習者於英語寫作上提供的協助功能有限，本研究致力於提出一種語言資訊檢索方法，能在不同的語言認知程度條件下，從語料庫中找出對使用者之寫作表達需求有參照作用之例句。此方法提供準確字詞、單字的開頭／結尾、英語詞性、一個單字的萬用字元、不限定的子句等表達元素，並使用完整比對或部分比對的兩種比對方式選取例句，而後對於選取的例句使用多重序列排列技術進行相關性評估，最後推薦最符合參照需求的例句。

Current language resource tools provide only limited help for ESL/EFL writing. This research proposes a language information retrieval approach to acquire referential sentences from corpus under various levels of users' language cognition. The approach includes a set of expression elements, such as exact words, prefix, suffix, part-of-speech, wildcard, and subsequence. Sentence retrieval involves both exact match and partial match with user query. Finally, the set of retrieved sentences are evaluated and ranked by multiple sequence alignment for relevance to user expression needs.
