Time-Based Microblog Search System

This demo shows a time-based microblog research system which developed based on the time profile to estimate the query model, the document model and rank function for microblog search. The system exploits the time profile to boost the performance of microblog search. A brief description of the time-based query model, time-based document model and time-based similarity score is introduced. The index strategy for temporal microblog search is described. Using TREC 2011 and TREC 2012 microblog retrieval collection, the examples of microblog search results are demonstrated.
