Constructing evolutionary taxonomy of collaborative tagging systems

Junjie Yao, Yuxin Huang, Bin Cui
2009 Proceeding of the 18th ACM conference on Information and knowledge management - CIKM '09  
The tags are generally correlated and evolving according to the change of web contents, and the popularity of tags represent evolution of social interests.  ...  In this demonstration, we propose to construct the evolutionary taxonomy which incorporates the correlation and evolution of tags, as user generated tags grow and change temporally.  ...  The constructed taxonomy can reflect the evolution of user interests and web contents, and facilitate the organization of online resources.

Identifying comparable entities on the web

Alpa Jain, Patrick Pantel
2009 Proceeding of the 18th ACM conference on Information and knowledge management - CIKM '09  
With this in mind, we present an initial step of mining comparable entities from sources of information available to a large-scale Web search engine, namely, search query logs and documents from a Web  ...  Richer interactions that explicitly allow for a comparative analysis of entities represent a new potential direction to improve the search experience.  ...  Another important problem is to explore further techniques to rank and score unreliable comparables without sacrificing the generality of the relation.

Semantic queries in databases

Lipyeow Lim, Haixun Wang, Min Wang
2009 Proceeding of the 18th ACM conference on Information and knowledge management - CIKM '09  
Using these examples as seeds, the system infers the exact query automatically, and the user is therefore shielded from the complexity of interfacing with the ontology.  ...  Instead of endeavoring to incorporate ontology into relational form and create new language constructs to express such queries, we ask the user to provide a small number of examples that satisfy the query  ...  To copy otherwise, to republish, to post on servers or to redistribute to lists, requires prior specific permission and/or a fee.
