本論文擴展進行文本一般性摘要的指標生成網路,建構一個給定查詢詞為輸入型式的查詢式摘要系統。本論文所提出模型以查詢詞標籤輔助從文本學習到查詢詞相關語意,並設計句意混合單元加強模型對句子層級語意的理解,用以有效生成與查詢詞相關的摘要結果。此外,以監督式學習的查詢式摘要生成系統需要足夠多的 <文本,查詢詞,查詢摘要> 資料進行模型訓練,但人工標示成本極高而不易取得。因此本論文提供一個自動化方法,根據語法分析從現有一般性摘要資料集轉換成查詢式摘要資料集的形式,以提供模型建構及測試用。實驗結果顯示本論文由CNN/Dailymail轉換產生的查詢式摘要資料集較相關研究能提供模型更好的訓練效果。且本論文所提查詢詞標籤輔助的查詢式摘要生成模型,能有效解決查詢詞為系統未知語意字彙而影響摘要生成效能的問題,並透過句意混和單元提升模型生成結果與查詢詞內容相關的精確度。
