| dc.description.abstract | 隨著科學文件發行量大增以及網路數位圖書館的便利，為了讓使用者可以找到與目標相關的研究文獻，如何能結構化及有效地索引科學文件是多數研究探討的議題，但卻少有研究針對個人科學文件管理提出解決方案，研究人員所下載儲存於個人硬碟的文件量與日俱增，階層式瀏覽檢索個人科學文件的方式不再如以往有效且缺乏效率，本研究即為提出一套新的個人科學文件管理系統LOCOST (Local Content Summary Tool)，可自動擷取處理科學文件中的文字，並設計使用者介面讓使用者搜尋科學文件，於搜尋結果中提供文件內容彙總，以供使用者於衡量文件重要性時一項決策參考，此外提供推薦關鍵字功能協助使用者尋找相關領域科學文件。
從本研究實驗結果可知：雖然使用者仍習慣於階層瀏覽方法，但LOCOST確實可以成為當瀏覽失敗時另一項替代的解決方案。

| dc.description.abstract | Since the rate of publishing scientific literature grows each year, the size of published work available online is increasing rapidly, and several web-based (digital library) systems were implemented. Related researches are focused on providing several useful methods for efficiently and effectively browsing and searching relevant scientific documents, but less on the issue how to manage personal scientific documents. On the other hand, researchers download scientific documents into their specific personal hard disk where they can categorize documents with hierarchical folders according to publication years, research topics, etc. for future retrieval. However, this turns into a critical issue of personal scientific document management that deals with how to effectively index and efficiently search personal scientific documents when her or his personal archive is inevitably getting larger and larger day by day.
LOCOST proposed in this paper can automatically processes the local sections of each document for term feature extraction. Therefore, users do not need to spend any time and effort to manually construct and maintain an organization system to manage their personal scientific documents. Moreover, LOCOST provides a useful interface for users to easily search important and/or relevant scientific document(s) from their archives. Particularly, the interface of LOCOST can display the content summaries of the retrieved documents that allow users to better understand the content of these documents and thus enable them to judge the level of importance and relevance of the retrieved documents to a given query. Consequently, LOCOST achieves ease of reusing personal scientific documents.
LOCOST is not developed to compete with related prototype systems, but it can be used to complement with each other since LOCOST provides unique functionalities for managing personal scientific documents. In addition, when the location-based finding strategy (or navigation) fails to achieve the users’ information needs, LOCOST is suitable at this time for the logical finding strategy.
