Despite substantial interest in applications of neural networks to information retrieval, neural ranking models have only been applied to standard ad hoc retrieval tasks over web pages and newswire documents ...
Extensive experiments using Twitter data from the TREC Microblog Tracks 2011--2014 show that our model significantly outperforms prior feature-based as well and existing neural ranking models. ...

The high momentum and large volumes of short texts bring redundancies and noises, in which the users and analysts often find it problematic to elicit useful information they are interested in. ...
Then we develop a ranking method to extract the most representative sentences relative to the query from the MCVs, and generate a query-focused summary of arbitrary time durations. ...
Therefore, how to summarize microblogs and help users digest the mass data has become a major issue in information retrieve and computational linguistics. ...
