Abstract: 科技的快速發展帶給我們許多便利,也使得生活上所得資訊不再只限於文字,而有了多媒體與語音文件。為了方便整理和快速瀏覽,我們先使用自動語音辨識將多媒體文件的語音訊號轉寫 (Transcribe) 為文字後再做處理,呈現。處理的方式包括分類、自動摘要 (Automatic Summarization)、和自動標題產生(Automatic Title Generation)等。
本論文除了探討純文字文件下的自動標題產生,另一個研究主題為針對經自動轉寫產生,與有錯誤的文件中做自動標題產生。論文中以語音新聞為例,探討辨識錯誤對自動標題產生的影響。
本論文內容主要分為三大部分:”建造式標題產生法基本型”、”建造式標題產生法之改進及用於自動轉寫有錯誤之文件”,以及”使用不同特徵單位於建造式標題產生法中”。出步實驗顯示若干效能的提升是做得到的。
Title generation is considered important in the near future for easy browsing and retrieving the multimedia document. The natural properties of titles are different from summaries, which make automatic title generation a more challenging task and hence not much improvement has been reported compared with automatic summarization. In this paper an improved non-extractive title generation method is developed. An evaluating data is first summarized and then with Viterbi beam search and various scores learnt form training corpus, we found the output title. Very positive results were btained.
