Anderson, James D.; Perez-Carballo, Jose – Information Processing & Management, 2001
Considers the role of human intellectual indexing in the face of increasingly sophisticated automatic indexing techniques. Critiques the comparative research and explores the nature of human analysis of messages or texts and efforts to formulate rules to make human practice more predictable. (Author/LRW)
Descriptors: Indexing, Literature Reviews

Kang, Byung-Ju; Choi, Key-Sun – Information Processing & Management, 2002
Discusses the need to index foreign words for information retrieval that are used in Korean text and presents an effective foreign word recognition and extraction method based on word segmentation. Uses both unknown word information acquired through the automatic dictionary compilation and foreign word recognition information. (Author/LRW)
Descriptors: Indexing, Information Retrieval, Korean, Word Recognition

Craven, Timothy C. – Information Processing & Management, 2001
Discusses automatic indexing methods and describes the development of a prototype computerized abstractor's assistant. Highlights include the text network management system, TEXNET; phrase selection that follows indexing; phrase display, including Boolean capabilities; results of preliminary testing; and availability of TEXNET software. (LRW)

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…

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…

Ogawa, Yasushi; Matsuda, Toru – Information Processing & Management, 1999
Discusses statistical word indexing for Japanese information-retrieval systems and proposes a new method that uses statistics about characters to evaluate a bi-gram's likelihood of being a word boundary. Describes a new segmentation strategy that extracts some overlapping segments and results in higher retrieval effectiveness. (Author/LRW)

Savoy, Jacques; Picard, Justin – Information Processing & Management, 2001
Discusses the role of search engines in Web usability and analyzes and evaluates the retrieval effectiveness of various indexing and searching strategies on a new Web text collection. Highlights include preprocessing techniques that might improve retrieval effectiveness; and hyperlinks as useful sources of evidence in improving retrieval…

Wu, Jian Kang; Narasimhalu, A. Desai – Information Processing & Management, 1998
Proposes a fuzzy-image database model and a concept of fuzzy space; describes fuzzy-query processing in fuzzy space and fuzzy indexing on complete fuzzy vectors; and uses an example image database, the computer-aided facial-image inference and retrieval system (CAFIIR), for explanation throughout. (Author/LRW)

Greenhill, Stewart; Venkatesh, Svetha – Information Processing & Management, 1999
Describes WebClass, a system that allows Web users to create personalized conceptual data that is dynamically merged with original HTML source by a proxy server. Explains the creation of alternative views of Web pages, data modeling, and navigation; and describes two possible applications of the system, annotation and indexing. (Author/LRW)

Chien, Lee-Feng – Information Processing & Management, 1999
Considers the need for keyphrase-extraction techniques in intelligent Chinese information retrieval and presents a PAT-tree-based adaptive approach, developed from the PATRICIA Algorithm (Practical Algorithm to Retrieve Information Coded in Alphanumeric). Discusses Internet utilization, automatic term suggestion, domain-specific lexicon…

Zhang, Xiaoyan; Berry, Michael W.; Raghavan, Padma – Information Processing & Management, 2001
Discusses latent semantic indexing (LSI); considers the high cost associated with the singular value decomposition (SVD) of the large term-by-document matrix that becomes a barrier for its application to scalable information retrieval; and shows that information filtering using level search techniques can reduce the SVD computation cost for LSI.…

Sanchez, D.; Chamorro-Martinez, J.; Vila, M. A. – Information Processing & Management, 2003
Discussion of multimedia libraries and the need for storage, indexing, and retrieval techniques focuses on the combination of computer vision and data mining techniques to model high-level concepts for image retrieval based on perceptual features of the human visual system. Uses fuzzy set theory to measure users' assessments and to capture users'…

Kim, Hak-Gyoon; Cho, Sung-Bae – Information Processing & Management, 2000
Discusses traditional information retrieval through indexing terms and describes a document storage and retrieval system based on structured information, where the SGML document is transformed into Grove (Graph Representation of Property Values) and stored at an element level by an object-oriented database management system. Also discusses query…

Arampatzis, A. T.; Tsoris, T.; Koster, C. H. A.; van der Weide, Th. P. – Information Processing & Management, 1998
Describes an information-retrieval schema that takes into account linguistic variation based on phrases. Introduces the phrase-retrieval hypothesis to replace the keyword-retrieval hypothesis, and discusses natural-language processing systems; syntactical, morphological, and lexico-semantical normalization; and future work. (Author/LRW)

Nelson, Michael J. – Information Processing & Management, 1997
Applies a prefix trie index, or trie hashing, to the problem of providing fast search times, fast load times, and fast update properties in a bibliographic or full-text retrieval system with inverted files. Statistics are given for a test database consisting of an online catalog at the University of Western Ontario. (Author/LRW)
