    It is indispensable to index stop-word before word segmentation in knowledge extraction.The key technique of processing stop-word is how to select stop-word,acquire and organize stop-word lists,and match stop-word.To recognize stop-word,constructing stop-word list is necessary.In processing stop-word,recognizing false stop-word can decrease noise.According to experiment,processing stop-word can not only save segment time,but also improve following syntactic analysis efficiency.

    XFML,standing for eXchangeable Faceted Metadata Language, exchanges metadata in the form of faceted hierarchies. Its basic building blocks are topics,also called categories. XFML can’t solve all the metadata’s needs. It focuses on interchanging faceted classification and indexing data.The background,concept,and data representation method of XFML and principles of Web indexing with XFML are discussed in this paper. As XFML is a new concept to Chinese,using XFML will benefit the develop of Web information organization in China.

    Statistics-based classification methods are common-used in hierarchical Web classification.However,classification precision of statistics-based methods often drops when categories are very similar to each other because of feature overlapping.Due to the nature of hierarchical Web classification,categories sharing the same parent (e.g.,leaf categories in the hierarchy) are often very similar to each other.To improve the classification precision,the paper proposes to use rule-based classification methods on top of statistics-based methods in hierarchical Web classification.Experiments show that our methods perform well on our education Web collections.

    The enterprise-level search engine is proposed to solve the problem that enterprise have abundant document information resources but lack of effective search tools.The function and the overall framework of the enterprise-level search engine are analyzed firstly.Lucene indexer is studied in depth during implementation secondly. Then the plug-in unit is used to carry out the analysis and extraction of different types of documentsi in design. A set of parallel multi-task scheduling mechanism is established in the task scheduling. When the user interface is designed,Yui-ext components and DWR remote object invocation framework is applied to implement asynchronous communication by the Web,which can promote the users’ experience.
