Age Dependent Document Priors in Link Structure Analysis

Much research has been performed investigating how links between web pages can be exploited in an Information Retrieval setting [1, 4]. In this poster, we investigate the application of the Barabási-Albert model to link structure analysis on a collection of web documents within the language modeling framework. Our model utilizes the web structure as described by a Scale Free Network and derives a document prior based on a web document’s age and linkage. Preliminary experiments indicate the utility of our approach over other current link structure algorithms and warrants further research.
