Our group submitted the OpenLiveQ task of NTCIR-13. With th openliveq tool offered from the organizers, we compare a baseline result with three results ranked by RF (Random Forests). It shows the result ranked by RF in 1000 bags is closest to baseline, but still lower in average.

In this paper, we present our approach to address the OpenLiveQ task at NTCIR-13 [5]. The task is a question retrieval task and can be simply defined as follows: given a query and a set of questions with their answers, return a ranked list of questions. However, there is a “gap” between queries and candidate questions, which is called lexical chasm or word mismatch problem. In our model, we imp...

SLWWW participated in the Chinese Subtask of the NTCIR13 WWW Task. We applied the query expansion methods based on word embeddings proposed by Kuzi, Shtok, and Kurland. However, according to our comparison with the baseline run, our runs were not successful. As the baseline run provided by the organisers was not included in the pools for constructing relevance assessments, we discuss condensed-...
