Information Retrieval Optimization Based on Tree of Social Network

Abstract

Abstract Information source such as the Web is a representation of social activities. Social activities create social structures that can be explored through social network concepts. Social networks not only show the structure of a social community, but prove the existence of its members and community. In that context, within the source of information, evidence of a community can be accessed through a collection of documents whose existence continues to increase, whereby the measurements can be performed using recall and precision. However, the recall and the precision as part of the measurement of information retrieval also requires technology to retrieve the related documents, an information retrieval based on network concepts. To solve it is proposed the concept of a collection of stars from trees and the degree of social actors in social networks, and produced a formula about the measurement of recall and precision with better results.
