If they find some words closely related to their target task of titles or abstracts, which are definedIf they find some words closely related to their target task of titles or abstracts, which are definedas intelligent sensitive words in this paper, they will decide to read these resources in depth tofind more useful information. These sensitive words may refer to special persons, organisations,programmes, terms and so on. All of these sensitive words and their featured information areincluded in our object. Basing on the above processes, we have determined that some featurescould be used for automatic computation.Downloaded by [National Science Library] at 03:28 19 January 2015 Profiling science and innovation policy by object-based computing 587?
