Mining topic-specific concepts and definitions on the web

Bing Liu, Chee Wee Chin, Hwee Tou Ng
2003 Proceedings of the twelfth international conference on World Wide Web - WWW '03  
In this paper, we attempt a novel and challenging task, mining topic-specific knowledge on the Web. Our goal is to help people learn in-depth knowledge of a topic systematically on the Web.  ...  The proposed techniques first identify those sub-topics or salient concepts of the topic, and then find and organize those informative pages, containing definitions and descriptions of the topic and sub-topics  ...  More importantly, the proposed technique integrates the two technologies (definition finding and salient concept discovery on the Web) to perform a novel task, i.e., mining and compiling topic-specific  ...

Efficient Conceptual Rule Mining on Text Clusters in Web Documents

V. M.Navaneethakumar, C. Chandrasekar
2012 International Journal of Computer Applications  
Clustering, one of the conventional data mining techniques is an unsubstantiated learning pattern where clustering techniques attempt to recognize intrinsic groupings of the text documents, so that a set  ...  Most current document clustering methods are based on the Vector Space Model (VSM)  ...  These semantic concepts wrap a broad assortment of topics that can be approximately classified as objects, sites, proceedings, and specific behaviors and named entities.  ...

ONTOLOGY TECHNIQUES FOR WEB DATA

A.ESWARA RAO, G. V. S. SOWMYA, P.N. SAILAKSHMI
2014 International Journal of Computer Science and Informatics  
The ontology model is evaluated by comparing it against benchmark models in web information gathering. The results show that this ontology model is successful.  ...  This paper p r e s e n t s techniques for knowledge description and formalization, ontologies are used to represent user profiles in personalized web data.  ...  We argue that a subject's specificity has two focuses: 1) on the referring-to concepts (called semantic specificity), and 2) on the given topic (called topic specificity).  ...

Refining the Results of Automatic E-Textbook Construction by Clustering

Jing Chen, Qing Li, Ling Feng
2007 International Journal of Distance Education Technologies  
The abundance of knowledge-rich information on the World Wide Web makes compiling an online etextbook both possible and necessary.  ...  The clustering approach serves as a post-processing stage to the original results retrieved by the search engine, and aims to reach an optimum state in which all Web pages assigned to a concept are discussing  ...  An important one (Liu, Chin, & Ng, 2003) is where the authors attempt to mine concept definitions of a specific topic on the Web.  ...
