Abstract

Abstractive summarization aims to generate a shorter version of the document covering all the salient points in a compact and coherent fashion.On the other hand, query-based summarization highlights those points that are relevant in the context of a given query.The encodeattend-decode paradigm has achieved notable success in machine translation, extractive summarization, dialog systems, etc.But it suffers from the drawback of generation of repeated phrases.In this work we propose a model for the query-based summarization task based on the encode-attend-decode paradigm with two key additions (i) a query attention model (in addition to document attention model) which learns to focus on different portions of the query at different time steps (instead of using a static representation for the query) and (ii) a new diversity based attention model which aims to alleviate the problem of repeating phrases in the summary.In order to enable the testing of this model we introduce a new query-based summarization dataset building on debatepedia.Our experiments show that with these two additions the proposed model clearly outperforms vanilla encode-attend-decode models with a gain of 28% (absolute) in ROUGE-L scores.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
