結合語意理解與知識圖譜之領域適應的自然語言介面

Integrating Linguistic and World Knowledge for Domain-Adaptable Natural Language Interfaces

指導教授 : 陳信希

摘要


隨著科技的不斷進步,智慧型裝置已經越來越普及;也因為運算能力的提升,許多智慧型裝置的應用也漸漸的深入民眾的生活各個層面,而其中自然語言界面的需求也越來越強烈。而在自然語言介面中,在應用裝置切換到各種領域時,領域適應性的議題是一個重要的挑戰。我們在本篇論文設計了一個自然語言介面的系統架構,結合語意知識以及世界知識來解決領域適應性的問題。只要我們給定一個目標領域的知識庫以及定義好的功能頁框,我們就可以利用這樣的架構,快速的建立起自然語言處理介面的系統。而我們嘗試實際建立一個中文的隨選視訊自然語言介面,並利用這個系統來進行檢索、測試效能。最後,我們利用此系統來實驗對話互動的過程,最後測試何種對話策略能得到最佳的使用者體驗。

並列摘要


Nowadays, natural language interfaces (NLIs) show strong demands on various smart devices from wearable devices, cell phones, televisions, to vehicles. Domain adaptation becomes one of the major challenging issues to sup-port the applications on different domains. In this paper, we propose a frame-work of domain-adaptable NLIs to integrate linguistic knowledge and world knowledge. Given a knowledge base of a target domain and the function definition of a target smart device, the corresponding NLI system is developed un-der the framework. In the experiments, we demonstrate a Chinese NLI system for a video on demand (VOD) service. Finally, we use this system to test the retrieval performance and find out which dialogue strategy is best for user experience.
