Figa, Elizabeth; Tarau, Paul – Proceedings of the ASIST Annual Meeting, 2003
Describes a framework for building "story traces" (compact global views of a narrative) and "story projects" (selections of key elements of a narrative) and their applications in text understanding and classification. The resulting "abstract story traces" provide a compact view of the underlying narrative's key…

Morato, Jorge; Llorens, J.; Genova, G.; Moreiro, J. A. – Information Processing & Management, 2003
Discusses the inclusion of contextual information in indexing and retrieval systems to improve results and the ability to carry out text analysis by means of linguistic knowledge. Presents research that investigated whether discourse variables have an impact on information and retrieval and classification algorithms. (Author/LRW)

Wolfram, Dietmar; Zhang, Jin – Journal of the American Society for Information Science and Technology, 2002
Investigates the influence of index term distributions and indexing exhaustivity on the document space within a visual information retrieval environment called DARE (Distance Angle Retrieval Environment). Discusses results that demonstrate the importance of term distribution and exhaustivity on the density of document spaces and their implications…

Lunin, Lois F. – Library Trends, 1990
A definition of fiber art, its history, materials and techniques, vocabularies, and creators and users of those vocabularies offer background for understanding the problems in preparing surrogates of this relatively recent art form for text and image databases. Four examples of fiber image information systems are described. (32 references) (EAM)

Lunin, Lois F.; Fidel, Raya – Journal of the American Society for Information Science, 1994
Introduces a series of eight articles that look at the intellectual or cognitive aspects of text and images from which researchers and system designers may derive new principles or refine those in use. Each article is briefly described, and background information on each author is provided. (KRN)

Burgin, Robert – Information Processing and Management, 1991
Describes results of a study that investigated the effect of variations in indexing exhaustivity on retrieval performance in a vector space retrieval system. The test collection of documents in the National Library of Medicine's Medline file indexed under cystic fibrosis is described, and use of the SMART information retrieval system is discussed.…

Breton, Ernest J. – Journal of the American Society for Information Science, 1991
Describes the development of a functional indexing system that is tailored to the thinking involved in the process of invention. Classification by function is discussed; matrix representation is explained; a controlled vocabulary of verbs, objects, and modifiers is described; and the relation to other indexing systems is examined. (13 references)…

Shaw, W. M., Jr. – Information Processing and Management, 1990
Investigates the presence of clustering structure in a document collection and the influence of the presence of clustering structure on the success of cluster-based retrieval. Term-weight and similarity thresholds are discussed, empirical and statistical significance are considered, and indexing exhaustivity for document representation is…

Lee, Joon Ho; Cho, Hyun Yang; Park, Hyouk Ro – Information Processing & Management, 1999
Discusses indexing methods in Korean text retrieval and proposes a new indexing method based on n-grams which can handle compound nouns effectively without dictionaries and complex linguistic knowledge. Experimental results show that n-gram-based indexing is considerably faster than morpheme-based indexing, and also provides better retrieval…

Thelwall, Mike – Internet Research, 2000
Reports on a survey of 60,087 commercial worldwide Web sites that investigated their design and rate of search engine registration. Discusses the need to register sites with search engines to make them more accessible to potential customers and recommends the use of HTML META tags for proper indexing. (Author/LRW)

Snow, Bonnie – Online, 2000
Discusses the growing gap between what is available on the Internet and what search engines can retrieve, particularly data lost in the breach of the unindexable, versus the unindexed, Web. Highlights include products designed to focus on content that is usually missed by search engines; and directories versus search engines. (Contains 10…

Perez-Carballo, Jose; Strzalkowski, Tomek – Information Processing & Management, 2000
Reports on the progress of the natural language information retrieval project, a joint effort led by GE (General Electric) Research, and its evaluation at the sixth TREC (Text Retrieval Conference). Discusses stream-based information retrieval, which uses alternative methods of document indexing; advanced linguistic streams; weighting; and query…

Horowitz, Stephen M.; Laflin, Molly T.; Nims, Julia K. – American Journal of Health Behavior, 1999
Investigated how health educators could improve literature searches and increase the accessibility of their research to others. A frequency count of databases indexed 84 health education journals and analyzed the 16 top indexes for journal coverage. Results indicated that selecting the appropriate indexes can help health educators more effectively…

Song, Sang Chul – ProQuest LLC, 2010
An unprecedented amount of information encompassing almost every facet of human activities across the world is generated daily in the form of zeros and ones, and that is often the only form in which such information is recorded. A good fraction of this information needs to be preserved for periods of time ranging from a few years to centuries.…
