A method that combines category - based and keyword - based concepts for a better information retrieval system is introduced. to improve document clustering, a document similarity measure based on cosine vector and keywords frequency in documents is proposed, but also with an input ontology. the ontology is domain specific and includes a list of keywords organized by degree of importance to the categories of the ontology, and by means of semantic knowledge, the ontology can improve the effects of document similarity measure and feedback of information retrieval systems. two approaches to evaluating the performance of this similarity measure and the comparison with standard cosine vector similarity measure are also described
介紹了一種綜合各層級分類類目和對應關鍵詞來構造概念體系並用於改進信息檢索系統效果的方法.為了改進文本聚類的效果，提出了將領域知識本體和文本關鍵詞詞頻相結合的基於餘弦向量的文本相似性測度方法.該本體面向特定領域，將關鍵詞以不同權值對應于各分類類目，通過其語義知識來改進文本相似性測度以及信息檢索系統的效果.進一步給出了對基於本體的相似性測度方法進行效果評價的2種策略以及該方法與經典餘弦向量測度方法的比較結果 -
Research and implementation of electronic document query system based on ontology and lucene
的電子公文查詢系統的研究與實現 -
In system design, we present dispatcher tactics of member search engine that user fond of. these member search engines on the basis of mobile agent, which provide an environment for parallel processing, take full advantage of ontology which expands the requirement of users to the semantic words set and provide the document analyzer that can filter the web pagers returned by the search mobile agent according to the certain algorithm. consequently wiirs presents the most relevant documents to the user
為提高系統的性能和易用性，還給出了基於用戶偏好的成員搜索引擎的調度策略，在成員搜索引擎系統結構中，不僅利用本四川大學碩士學位論文體論中概念規范、語義豐富的特點，將用戶的檢索要求擴充成語義集，並且將檢索到的文檔通過文檔分析器進一步過濾，最終得到與用戶檢索要求內容匹配度較高的文檔，而且提供了一個并行處理的環境來顯著提高搜索效率。 -
Based on this, a new approach to extracting information from normal document based on an application ontology is presented that describes a domain of interest

Study of ontology - based document classification system
基於本體的文檔自動分類系統的研究 -
Dkow is capable of modeling and reasoning static domain knowledge, including domain structures, concepts and properties of the concepts, and the relations among concepts, etc. in order to apply the power of domain ontology to express the semantic information of web data, the author presents an algorithm named dtd generating from domain ontology ( dtdgdo ) that maps a given ontology to a document type definition ( dtd ) based on the transformation rules
作者提出了一種基於領域本體的web數據語義信息的表示方法，設計了dkow構建的形式化領域本體到相應dtd的生成演算法dtdgdo 。作者在屬性定義方面增強了現有ecfgs方法對dtd模型的定義，設計了生成演算法dtdgdo的三類轉換規則：重組規則、變換規則、基數規則。
