representing 100% of site traffic during these periods and 2,029,734 queries overall. The results show that the highest percentage of queries contained two terms. The highest percentage of search sessions contained one query and was less than 1 minute in duration. Almost half of user interactions with clusters consisted of displaying a cluster's result set, and a small percentage of interaction...

We propose a goal-oriented evaluation measure, Hierarchy Quality, for hierarchical clustering algorithms applied to the task of organizing search results -such as the clusters generated by Vivisimo search engine-. Our metric considers the content of the clusters, their hierarchical arrangement, and the effort required to find relevant information by traversing the hierarchy starting from the to...

Web search engine interfaces typically return search results as lists of Web links accompanied by brief textual summaries. An improvement on this results interface design has been introduced with the use of clusters. Clusters represent groups of similar items and are used to aggregate search results. Operational Web interfaces containing cluster representations are relatively new. This paper pr...

Web page clustering techniques categorize & organize search results into semantically meaningful clusters that assist users to search relevant information quickly. In general, it provides a solution for data management, information locating & interpretation of web data. Also facilitate users for discrimination, navigation & organization of web pages. Finding information on the World Wide Web is...

This paper describes Armil, a meta-search engine that groups into disjoint labelled clusters the Web snippets returned by auxiliary search engines. The cluster labels generated by Armil provide the user with a compact guide to assessing the relevance of each cluster to her information need. Striking the right balance between running time and cluster well-formedness was a key point in the design...

AIM To determine the accuracy of computed tomography (CT) in detecting disease with invasion beyond the muscularis propria (MP) and malignant lymph nodes. MATERIALS AND METHODS A literature search of Ovid, Embase, the Cochrane database, and Medline using Pubmed, Google Scholar and Vivisimo search engines was performed to identify studies reporting on the accuracy of CT to predict the staging ...
