Motivation

User browse Wikipedia content in the traditional manner when searching for information

users may unconsciously change their search goals or get lost when exploring or retrieving information in Wikipedia

Objectives

• Our goal is to develop an application that helps users find related articles for a seed query (topic)easily and then quickly check the content of articles to explore a new concept or topic in Wikipedia.
