This has enabled new forms of automatic text analysis and has given rise to some interesting questions: How informative is the abstract compared to the full-text? What important information in the full-text is not present in the abstract? What should a good summary contain that is not already in the abstract? Do authors and peers see an article differently? We answer these questions by comparing the information content of the abstract to that in citances¡ªsentences containing citations to that article. We contrast the important points of an article as judged by its authors versus as seen by peers. Focusing on the area of molecular interactions, we perform manual and automatic analysis, and we find that the set of all citances to a target article not only covers most information (entities, functions, experimental methods, and other biological concepts) found in its abstract, but also contains 20% more concepts. We further present a detailed summary of the differences across information types, and we examine the effects other citations and time have on the content of citances. 1. Introduction Text mining research in biosciences is concerned with how to extract biologically interesting information from journal articles and other written documents. To date, much of biomedical text processing has been performed on titles, abstracts, and other metadata available for journal articles in PubMed1, as opposed to using full text. While the advantages of full text compared to abstracts have been widely recognized [1¨C5], until relatively recently, full text was rarely available online, and intellectual property constraints remain even to the present day. These latter constraints are loosening as open access (OA) publications are gaining popularity and online full text is gradually becoming the norm. This trend started in October 2006, when the Wellcome Trust2, a major UK funding body, changed the conditions of grants, requiring that ¡°research papers partly or wholly funded by the Wellcome Trust must be made freely accessible via PubMed Central3 (PMC) (or UK PubMed Central once established) as soon as possible, and in any event no later than six months after publication¡± [6]. Canadian Institutes of Health Research followed, as did the National Institute of Health (NIH) in the USA in April 2008.4 Moreover, many publishers founded and promoted OA initiatives, namely, BioMed Central5 (BMC) and the Public Library of Science6 %U http://www.hindawi.com/journals/abi/2012/750214/
