Lin, P. L.; Tan, W. H. – Information Processing & Management, 2003
Presents a new method to improve the performance of query processing in a spatial database. Experiments demonstrated that performance of database systems can be improved because both the number of objects accessed and number of objects requiring detailed inspection are much less than those in the previous approach.

Mehtre, Babu M.; Kankanhalli, Mohan S.; Lee, Wing Foon – Information Processing & Management, 1998
Proposes a composite feature measure which combines the shape and color features of an image based on a clustering technique. A similarity measure computes the degree of match between a given pair of images; this technique can be used for content-based image retrieval of images using shape and/or color. Tests the technique on two image databases;…

Spink, Amanda; Goodrum, Abby; Robins, David – Information Processing & Management, 1998
Elicitations study during 40 mediated information retrieval (IR) interactions identified 1557 search intermediary elicitations within 15 purpose categories (requests for information on search terms and strategies, database selection, search procedures, system's outputs and relevance of retrieved items, and users' knowledge and previous…

Oard, Douglas W.; Resnik, Philip – Information Processing & Management, 1999
In systems that support query-based searching, the presence of multilingual content affects the search technology and user interface components that support query formulation, document selection, and query refinement. A categorization-based selection model is described that is based on rapidly constructed word-by-word gloss translations. An…

Kim, Dongseok; Jung, Hanmin; Lee, Gary Geunbae – Information Processing & Management, 2003
Presents a new extraction pattern, modified Document Type Definition (mDTD), which relies on analytical interpretation to identify extraction target from the contents of Web documents. Experiments with 330 Korean and 220 English Web documents on audio and video shopping sites yielded an average extraction precision of 91.3% for Korean and 81.9%…

Niemi, Timo; Jarvelin, Kalervo – Information Processing & Management, 1995
Discusses a user interface that simplifies NF Squared (non-first-normal-form) relational query formulation in which query specification remains compact and straightforward. This interface allows for nesting and general hierarchical structures and restructuring which provides for more effective retrieval and query formulation. (Author/JKP)

Larson, Ray R. – Information Processing & Management, 2001
Describes the University of California at Berkeley's participation in the TREC (Text Retrieval Conference) interactive track experiments. Highlights include results of searches on two systems, Cheshire II and ZPRISE; system design goals and implementation; precision and recall results; search questions by topic and system; and results of…

Bates, Marcia J. – Information Processing & Management, 2002
Presents a model of some of the typical important layers in the design of information systems, and shows how those layers interact in operation. Suggests that these layers are in the way of a cascade of each layer affecting the next. Presents a model of this cascade of interactions in information systems. Provides examples from networked…

Marchionini, Gary; Mu, Xiangming – Information Processing & Management, 2003
Describes a series of user studies used to advance understanding of how people use electronic tables (E-tables) and inform the development of a Web-based statistical table browser for use by non-specialists. Results of needs assessment, prototype development, and user studies provide a foundation for understanding E-tables in general and guiding…

Rothkegel, Annely – Information Processing & Management, 1995
A text production model is considered as an instrument for researching the writing strategies of abstractors. Within this framework, abstracting is a subtype of the writer's activities, which are described in terms of text actions. A computer system can be constructed that evaluates and/or supports human text production. (Author/AEF)

Chignell, Mark H.; Gwizdka, Jacek; Bodner, Richard C. – Information Processing & Management, 1999
Introduces an evaluative framework for metasearch engine performance and illustrates its use in two experiments. Results are used to characterize some properties of leading search engines (as of 1998). Significant interactions were observed between search engine and two other factors: time of day and Web domain. (Author/AEF)

Cohen, Jonathan D. – Information Processing & Management, 1998
Describes a method of full-text scanning for matches in a large dictionary. The method is suitable for selective dissemination of information systems, accommodating large dictionaries and typical digital data rates. It can be implemented on a single commercially-available board hosted by a personal computer or entirely in software. (Author/AEF)

Blair, David C.; Kimbrough, Steven O. – Information Processing & Management, 2002
Suggests an alternative document representation method based on "exemplary documents," those that describe or exhibit the intellectual structure of a particular field of interest. Exemplary documents provide both an indexing vocabulary for that area and a narrative context in which the indexing terms have a clearer meaning. It is much…

Spink, Amanda; Goodrum, Abby – Information Processing & Management, 1996
Reports findings from an exploratory study investigating working notes created during encoding and external storage (EES) processes by human search intermediaries (librarians at the University of North Texas) using a Boolean information retrieval (IR) system. Implications for the design of IR interfaces and further research is discussed.…

Chen, Hsin-liang – Information Processing & Management, 2001
Investigated undergraduate art history majors' image retrieval tasks and image query modes. Discusses gender differences; prior information retrieval experience; significant differences between the number of search terms users planned to use and the number they actually used; and implications for image indexing tools, image retrieval system…
