Information Retrieval from Social Network

Social networks are very popular these days, and it facilitates search and retrieval of information through internet. Hence, our understanding and usage of the WWW significantly differs from early days. The Internet, particularly the WWW is not only being used and approached for gathering information anymore. It is used routinely to reach other people through various applications ranging from email, chats, community platforms and social network sites. The current development of the WWW increasingly allows more people to publish information in social networks. Whereas users have changed from passive recipients of information to active content consumers and creators, and the nature of information has also changed from static text to dynamic multimedia. With the widespread use of social networks, live User-Defined Information (UDI) has begun to overcome the Internet. Such UDI covers a range of social network. More research works have focused on analyzing, organizing, indexing, and retrieving information, search for dynamic and live UDI‟s from the web. However, research efforts to make sense of the huge and unstructured UDI have begun. Social networks and multimedia content sharing Web sites have become increasingly popular in recent years. Information Retrieval is one of the most focused research area which motivate us to concentrate on this field.
