Yue Wang, Jerry Darko, Hui Min Fang · Text REtrieval Conference · 2013
Microblog retrieval is the key tool that enables users to access the relevant information from the enormous tweets posted on social media. Due to the differences of the tweets and traditional documents, existing IR models might not be the optimal choice for this problem. In this paper, we aim to introduce a new idea, i.e., tie-breaking, and discuss its implication in ranking methods and evaluation measures for microblog retrieval.
