Web Data Mining is an important area of Data Mining which deals with the extraction of interesting knowledge from the World Wide Web. It defines the application of data mining techniques to extract knowledge from web data, including web documents, hyperlinks between documents, usage logs of web sites, etc. Therefore, the process of extracting useful information from the contents of web document...

by Jin Xu The evolution of the World Wide Web has brought us enormous and ever growing amounts of data and information. With the abundant data provided by the web, it has become an important resource for research. Design and implementation of a web mining research support system has become a challenge for people with interest in utilizing information from the web for their research. However, tr...

Domain-oriented web page extraction is a new and practical direction in the field of information extraction. The paper focuses on the representation of domain-oriented web page topic features, and hierarchical vector space (HVS) model is put forward. Considering the hierarchical characteristics of the web page itself, topic features of the web page are expressed more effectively by HVS model fr...

In this paper we discuss the possible application of new concepts in web content extraction: utility assessment, utility annealing, and dynamic aggregated document generation. After analysis of the state of the art in web content extraction, results of a survey study among Polish managers are presented. The discussion covers a web content extraction system with possible extensions that may help...

Information extraction (IE) is an important problem for information integration with broad applications. It is an attractive application for machine learning. The core of this problem is to learn extraction rules from given input. This paper extends a pattern discovery approach called IEPAD to the rapid generation of information extractors that can extract structured data from semi-structuredWe...

In this paper we present how the use of a general-purpose text engineering platform has facilitated the development of a cross-lingual information extraction system and its adaptation to new domains and languages. Our approach for crosslingual information extraction from the Web covers all the way from the identification of Web sites of interest, to the location of the domainspecific Web pages,...
