Jarvelin, Kalervo; Niemi, Timo – Information Processing & Management, 1999
Shows that in advanced information-retrieval applications capabilities for data aggregation, transitive computation and non-first normal-form relational computation are often necessary at the same time. Topics include complex objects; advanced data models; query languages; query formulation; knowledge representation; and query-language syntax.…

Koyama, Masafumi; Morita, Kazuhiro; Fuketa, Masao; Aoe, Jun-Ichi – Information Processing & Management, 1998
Presents a faster method for determining hierarchical relationships in information retrieval by using trie structures instead of a linear storage of a concept code. Highlights include case structures, a knowledge representation for natural-language understanding with semantic constraints; a compression algorithm of tries; and evaluation.…

Ford, Nigel – Journal of Documentation, 1999
Discusses the requirements of information retrieval systems to support creative thinking as well as more convergent thinking. Highlights include the nature of creative thinking; similarity relationships; serendipity; machine processing of similarities; high order knowledge representation; and fuzzy and parallel information retrieval. (Contains 34…

Kwasnik, Barbara H. – Library Trends, 1999
The link between classification and knowledge is explored. The strengths and limitations of four classificatory approaches (hierarchies, trees, paradigms, and faceted analysis) are described in terms of their ability to reflect, discover, and create new knowledge. Examples are provided of the way in which knowledge and the classification process…

Atlam, El-Sayed; Morita, K.; Fuketa, M.; Aoe, Jun-ichi – Information Processing & Management, 2002
Discusses automatic document classification and document retrieval systems and presents a strategy for building a morphological machine dictionary of English that infers meaning of derivations by considering morphological affixes and their semantic classification. Proposes a method for selecting compound field association terms from a large pool…

Panyr, Jiri – Review of Information Science, 1996
Discusses object-centered knowledge representation and information retrieval. Highlights include semantic networks; frames; predicative (declarative) and associative knowledge; cluster analysis; creation of subconcepts and superconcepts; automatic classification; hierarchies and pseudohierarchies; graph theory; term classification; clustering of…

Scheuermann, Peter; Li, Wen-Syan; Clifton, Chris – Journal of the American Society for Information Science, 1998
Presents an approach for dynamic database integration and query processing in the absence of information about attribute correspondences and global IDs. Defines different types of equivalence conditions for the construction of global IDs. Proposes a strategy based on ranked role-sets that makes use of an automated semantic integration procedure…

Ingwersen, Peter – Journal of Documentation, 1996
Discusses the basic elements of a global cognitive theory for information retrieval (IR) interaction from a cognitive point of view. Within this framework are outlined the principles underlying the concept of polyrepresentation applied simultaneously to the user's cognitive space and the information space of IR systems. Contains 95 references.…

Rowe, Jeremy; Razdan, Anshuman – 2003
The Partnership for Research in Spatial Modeling (PRISM) project at Arizona State University (ASU) developed modeling and analytic tools to respond to the limitations of two-dimensional (2D) data representations perceived by affiliated discipline scientists, and to take advantage of the enhanced capabilities of three-dimensional (3D) data that…

Norton, M. Jay – Library Trends, 1999
Knowledge discovery in databases (KDD) revolves around the investigation and creation of knowledge, processes, algorithms, and mechanisms for retrieving knowledge from data collections. The article is an introductory overview of KDD. The rationale and environment of its development and applications are discussed. Issues related to database design…

Rousseau, Ronald – Information Processing & Management, 1998
Demonstrates that if the similarity function of a retrieval system leads to a (pseudo-) metric, the retrieval, similarity and Everett-Cater metric topology coincide and are different from the discrete topology; this is the case if documents are represented by lists, using the Jaccard similarity measure. The corresponding metric is the…

Raggad, Bel Gacem – Information Processing & Management, 1996
A consultation quality control model (CQCM) developed for an expert system (ES) integrated both ES performance measures and end-user judgment values. Simple decision theory concepts were used to design the CQCM. Results show end users belong to different categories characterized by utility functions and the weights they assign to ES consultation…

Lopez-Huertas, Maria J. – Journal of Documentation, 1997
Explores creating a thesaurus from a cognitive viewpoint, based on a system that organizes its knowledge representation/classification according to the authors' and users' images of the subject domain, in order to increase user-text interaction. Discusses the general framework, methods for implementing author-text structures, and an approach…
