It Is difficult to manage broken link with dangling reference, inaccurate reference m the manual site that is consist of HTML documents of much quantity as KLDP(Korean Linux Documentation Project, http:/ /kldp.org) Web site. In this paper. we define relationship and constrain renditions that exist between Web site's HTML documents. And we design and implement HIMS(HTML Document Integrity Management System), which notify user that integrity violation happens or launch trigger operation to keep integrity between HTML documents in case of insert, delete, update.

Recently, WWW(World Wide Web) has become a source of a large amount of information, and is now recognized not only as an information-sharing tool, but also as an information repository. Currently, the majority of documents on the web were created using HTML(Hypertext Markup Language). Although HTML is simple and easy to learn, its inherent lack of describing document structure makes it difficult to retrieve information effectively. One possible solution would be to convert such HTML documents into XML (extensible Markup Language) documents. This is a standard markup language for exchanging data on the web. It can describe a document structure freely by defining its own DTD (Document Type Definition). This makes it possible to integrate, store, and retrieve data on the web efficiently In this paper, we will propose a converter that automatically converts HTML documents with similar pattern into XML documents by analyzing the document structure and recognizing its path information.

A genre or a style is another view of documents different from a subject or a topic. The style is also a criterion to classify the documents. There have been several studies on detecting a style of textual documents. However, only a few of them dealt with web documents. In this paper we suggest sets of features to detect styles of web documents. Web documents are different from textual documents in that Dey contain URL and HTML tags within the pages. We introduce the features specific to web documents, which are extracted from URL and HTML tags. Experimental results enable us to evaluate their characteristics and performances.

With its recent popularity, Web is now considered as a huge repository of information. Most documents on the web have been created using HTML(Hyper Text Markup Language). Even though HTML is simple and easy to learn, it has several features that are obstacles to the efficient information retrieval. XML(eXtensible Markup Language) can provide a solution to such problems and in fact, has already been used in many applications, XML is a standard markup language for exchanging data on the web. It can describe a document structure freely by defining its DTD, which enables efficient integration and retrieval of data on the web. In this paper, we propose a versatile and efficient XML document manager. Its features include (i) form-based XML editor that enables easy creation of new XML documents, (ii) automatic document converter that can transform HTML documents with similar structure into XML documents automatically, and (iii) GUI-based DTD editor.

In this paper, we propose a design and implementation of HTML Filter to provide wireless internet service efficiently. The HTML Filter translates the Web documents written by HTML into the WML documents for portable wireless equipments automatically that are suitable for the WAP environment. The HTML Filter consists of "the HTML lexical analyzer" which gathers HTML source into token units, "the HTML syntax analyzer" which takes the lexical units from the lexical analyzer and analyses grammar for the source, "the HTML abstract parser tree" which can represent meaning of HTML sources more effectively called an intermediate code, and "the target code generator" which can convert the abstract parser tree into WML documents. The proposed translating method using ordinary compiler technology provides more easy and effective than the existing converters, and will be applied to other wireless language translating methods on wireless internet.

웹에 데이터를 나타내기 위해서 사용하는 HTML은 데이터를 표시(presentation)하기 위한 언어일 뿐 데이터의 의미를 나타내지는 못한다. 이러한 HTML의 단점을 극복하고 데이터의 표시(presentation)와 의미(semantic)를 나타낼 수 있도록 한 마크업 언어가 XML이다. HTML로 나타난 정보를 제대로 이용하기 위해서는 HTML 문서의 의미(semantic)정보를 알아내야만 한다. HTML 문서를 XML 문서로 변경할 수 있다면, 변경된 문서의 의미 정보를 이용할 수 있을 것이다. HTML 문서 포멧(format)을 XML 문서 포멧(format)으로 변경하기 위한 작업으로 [1]이 있다. [1]에서는 자동으로(automatic) 변환하는 방법을 사용했다. 이러한 방법은 프로그램이 HTML 문서의 의미를 파악하는데 한계가 있기 때문에 변환된 XML 문서에서 문서의 의미를 제대로 나타내기 어렵다는 단점을 안고 있다. 본 논문에서는 HTML 문서의 의미론 제대로 나타내는 XML 문서를 만들기 위해서 사용자가 어느 정도 개려하여 최종적인 XML 문서를 만드는 방법을 제안한다. 제안한 방법은 사용자의 약간의 개입으로 원래 HTML 문서의 의미를 보다 더 잘 나타내는 XML 문서를 만들어낸다.

Most of existing expert systems developed for Web use CGI-based techniques and this frequently makes them suffer from the overburden of commercial Web servers, which deal with large-scale services. However, since HTML-based inference technique represents expert's knowledge by hyperlinks among HTML documents, the hypertext function of the Web can perform the inference efficiently in terms of time and space without the help of additional inference engines. In spite of such benefits, when the expert's knowledge is relatively large and/or complicated, the HTML-based inference technique has usually become to have a hard time of dealing with a lot of HTML documents because generation and management tasks of the numerous HTML documents would cause big trouble to the knowledge engineer. To resolve this problem, we developed an automatic generation and management tool for Web-based inference sites, called WeBIS. With this tool, a knowledge engineer can input and edit expert's knowledge using Expert's Diagram on the GUI(Graphical User Interface) environment and automatically generate hyper-linked HTML documents for Web-based inference from the Expert's Diagram.

This study addreses the design and implrmentation of korean SGML(Standard Generalized Markup Langu-age)editor capable of ggenerating DTD(Document Type Definition)s,which can be used at the same time to gen-erate HTML documents as well] as SGML documents using interactive method.HTML is an appkication of SGML and HTML DTD is defined according to the syntax of SGML.Therefore it is possible to generate HTML documents of any versions by replacing the corresponding DTDs and using the implemented editor.This system has been implemented using GUI such as Motif and UIL(User Interface Language)in X-window system and C-language for common modules of functions.

To access massive and various HTML documents that are in the web using wireless Internet equipments, another WML document that is equal to the HTML document must be written, In the case Web documents written by HTML are massive, the construction of a WML site with the same information needs much cost of space and time, This paper designs and implements the HTML-XML converter that alleviates such a problem. The HTML-WML converter translates the Web document written by HTML to the WML document for portable wireless equipments, The HTML-XML converter has advantages that it reconstructs WML document dynamically according to portable wireless equipments and processes various image formats such as GIF, JPG, BMP, and so on, The HTML-WML converter can be used as not only a utility of the WML editor but also a real-time converter on wireless Internet.

< TABLE > tags in HTML documents are widely used for formatting layout of Web documents as well as for describing genuine tables with relational information. As a prerequisite for information extraction from the Web, this paper presents an efficient method for sophisticated table detection. The proposed method consists of two phases: preprocessing and attribute-value relations extraction. For the preprocessing where genuine or ungenuine tables are filtered out, appropriate rules are devised based on a careful examination of general characteristics of < TABLE > tags. The remaining is detected at the attribute-value relations extraction phase. Specifically, a value area is extracted and checked out whether there is a syntactic coherency Futhermore, the method looks for a semantic coherency between an attribute area and a value area of a table that may be inappropriate for the syntactic coherency checkup. Experimental results with 11,477 < TABLE > tags from 1,393 HTML documents show at the method has performed better compared with previous works, resulting in a precision of 97.54% and a recall of 99.22% in average.
