Summary in context

Daniel M. McDonald, Hsinchun Chen
2006 ACM Transactions on Information Systems  
Despite these wellresearched needs for context, text summaries provided by Web search engines remain consistently query based at the expense of page-level context.  ...  We end the literature review by discussing the different types of information-seeking tasks and how document context has been shown to be useful in browsing tasks.  ...  ACKNOWLEDGMENTS We would like to thank Kathy McKeown and Hongyan Jing for allowing us to use their TREC summarization data.  ...

Remedies against the Vocabulary Gap in Information Retrieval [article]

Christophe Van Gysel
2017 arXiv   pre-print
Search engines rely heavily on term-based approaches that represent queries and documents as bags of words.  ...  However, it is known that a high matching degree at the term level does not necessarily mean high relevance and, vice versa, documents that match null query terms may still be relevant.  ...  task of the TREC Enterprise track from 2005 to 2008 [245].  ...
