Partitioning and Segment Organization Strategies for Real-Time Selective Search on Document Streams

Yulu Wang, Jimmy Lin
2017 Proceedings of the Tenth ACM International Conference on Web Search and Data Mining - WSDM '17  
The basic idea behind selective search is to partition a collection into topical clusters, and for each query, consider only a subset of the clusters that are likely to contain relevant documents.  ...  In our approach, documents are partitioned into temporal segments and selective search is performed within each segment: these segments can either be clustered using batch or online algorithms, and at  ...  We thank the reviewers and particularly the meta-reviewer for their helpful comments and guidance.  ...

Disambiguating Implicit Temporal Queries by Clustering Top Relevant Dates in Web Snippets

Ricardo Campos, Alipio Mario Jorge, Gael Dias, Celia Nunes
2012 2012 IEEE/WIC/ACM International Conferences on Web Intelligence and Intelligent Agent Technology  
We used several measures for evaluating the performance of the system and compared our approach with Carrot Web-snippet clustering engine. Both experiments were complemented with a user survey.  ...  For example, when querying "Football World Cup Germany", it would be interesting to have two separate clusters corresponding to each of the two temporal instances.  ...  This work is funded by the ERDF through the Programme COMPETE and by the Portuguese Government through FCT -Foundation for Science and Technology and grant (Reference: SFRH/BD/63646/2009).  ...
