As growing attention. Query-focused summarization is the process

As the amount of
online information increases, the task of query-focused multi-document
summarization has received growing attention. Query-focused summarization is
the process of summarizing document clusters in response to a specific input
query. This literature review gives a broad insight into the recent growth in
extractive query-focused multi-document summarization methods.  It also explains the state-of-the-art research
in this area. Moreover, the effectiveness, limitations, and the most common
quality evaluation measures of the different methods were described. This paper acknowledges some of the challenging
problems persist. Most importantly, the demand for a collective approach that
combines varied methods that would lead
to the best coherent, non-redundant, and concise summary in response to a user
query. This review could be the first step in
developing a hybrid of different approaches that will yield good results for
varied types of documents.
