Abstract

In this paper, we present a novel approach for the managing the clarity of queries which users post to a knowledge portal. The approach is based on the (i) measuring the ambiguity of a query and (ii) suggesting the refinement of the original query, based on various ambiguity analyses: structure of the query, knowledge repository and user’ behaviours. The approach is mainly based on tracking users’ interactions with the portal. Since the approach requires more semantic information about users’ querying activities (for example, how many results are retrieved), which are not contained in the traditional Web server log, we have developed the new, client-based, method for tracking users’ activities which is presented in the paper as well. The short evaluation study shows the benefits of applying our approach in a real-world portal.

According to the KPMG Knowledge Management Report 2000, based on the 423 CEOs, CFOs, Marketing Directors from US/Europe: “65% of organizations that have implemented a knowledge management system still complain of information overload”.
