Projects


  • Temporal Summarization- Sequential update summarization, L3S Research Center, Leibniz University

    TREC’s Temporal Summarization Track provides an opportunity to evaluate systems seeking to generate temporal summaries which provide users with timely updates during an event like protests or hostage crises. I adopted the following approach to select update sentences for each hour: First I retrieved the top-m documents for the query to account for prevalence, then I selected the top-q summary-worthy sentences using a learning to rank model, LambdaMart. For training LambdaMart, I used features like variations of unigram frequencies, presence of numerical entities, sumbasic, mutual information and query overlap. Next, I removed redundancy using Minhash based clustering and finally filtered by information gain to select novel updates. I tuned the parameters for best performance using a few topics and evaluations from the 2014 TREC TS task coupled with judgments of my own. I successfully generated three runs which were validated and submitted by L3S for the 2015 task (team id: l3sattrec15).
