Title:
Revealing Hidden Community Structures and Identifying Bridges in Complex
Networks: An Application to Analyzing Contents of Web Pages for Browsing
Abstract
The emergence of scale free and small world properties in
real world complex networks has stimulated lots of activity
in the field of network analysis. An example of such a
network comes from the field of Content Analysis (CA) and
Text Mining where the goal is to analyze the contents of a
set of web pages. The Network can be represented by the
words appearing in the web pages as nodes and the edges
representing a relation between two words if they appear in a
document together. In this paper we present a CA system that
helps users analyze these networks representing the textual
contents of a set of web pages visually. Major contributions
include a methodology to cluster complex networks based
on duplication of nodes and identification of bridges i.e.
words that might be of user interest but have a low frequency
in the document corpus. We have tested this system with a
number of data sets and users have found it very useful for
the exploration of data. One of the case studies is presented
in detail which is based on browsing a collection of web
pages on Wikipedia. |
