Semantic Web Mining Model
Introduction(1/2)
since the majority of Web data is
unstructured, which lead to the traditional
data mining results will be unsatisfactory
Improve Web service levels and address the
existing Web services which is supported by
the lack of semantic problem
Introduction(2/2)
 Semantic-based Web data mining
=Semantic Web + Web mining
Web mining
Extract interested, useful patterns and implicit information from the
WWW resources and behavior

方法
Web Mining Types : Content
 Web Content Mining is a form of text mining
 The primary Web resource that is being mined is
an individual page
 Web content mining can take advantage of the
semi-structured nature of Web page text
 Web content mining can be used to detect
co-occurrences of terms in texts
Web Mining Types : Structure
 Usually operates on the hyperlink structure of Web pages
 The primary Web resource that is being mined is a set of
pages, ranging from a single Web site to the Web as a
whole
 Exploits the additional information that is (often implicitly)
contained in the structure of hypertext.
Web Mining Types : Usage
 The primary Web resource that is being mined is a record
of the requests made by visitors to a Web site, most often
collected in a Web server log.
 It is useful to combine Web usage mining with content
and structure analysis in order to “make sense” of
observed frequent paths and the pages on these paths
 It is also used for static site improvement by identifying
navigational pattern of the user inside a Website.
Semantic Web
that embed machine-readable, on behalf of certain types of knowledge
mark in the Web message
Semantic Web Mining Model
WSMO is a conceptual model for describing(SWS)s. It consists of
four components, describing semantic aspects of (WS)s:
建立初始本體
(取得核心概念)
透過Ontology Agent處
理，整理新的資料數據
RDF clustering module
實現本體的資料來源
將RDF database提供給
Semantic web Mining module
再由Ontology Agent過濾
和處理群組，得出結果
Thank You!
