CONCLUSIONS AND FUTURE WORKIn this paper we presented a novel tool called QueryCloud for exploring related resources in Webencyclopedias. The tool aims at offering additional navigational paths to related resources for users of suchsystems in general, and for users who come to these systems from a search engine such as Google, Yahoo! orBing. Furthermore we introduced a theoretical framework to evaluate potentials and limitations of the toolfrom a “network” perspective. As the experiments showed, QueryCloud system provides a great alternativeto traditional forms of tagging to automatically linking related documents via resource-specific query tagclouds in Web cyclopedia systems. The approach showed that the system is able to produce a good amount oftags which are of good “link” quality and tag cloud networks with are of good “network” quality. Moreover,the tool showed that the tag cloud network produced by QueryCloud system is efficiently navigable, i.e.related document are retrievable in an efficient way.Future work will include evaluation of QueryCloud system with real users. Thus, we plan to deployQueryCloud system on Austria-Forum life server to track and evaluate the users’ click paths to compare it241
