Improving Context Awareness Information Retrieval with Online Social Networks

There are many attempts to optimize information retrieval using various social concepts such as social annotations and social book marking. This paper explores the convergence of the information retrieval technique, the social network and the context-aware computing in order to improve information retrieval services. We propose a new ranking algorithm for the context-aware information retrieval. To do this, we get ideas from the social network, previous graph theory and the context-aware computing. Therefore, we investigate the problem of the information retrieval system in ubiquitous computing environment.
