Terminological Knowledge Structure for Intermediary Expert Systems.
Peer reviewed Peer reviewed
Fidel, Raya; Efthimiadis, Efthimis N. – Information Processing & Management, 1995
Examines the knowledge base of an intermediary expert system that provides advice about search term selection. Topics include a proposal for an integrated approach, including an option focusing on terminological attributes based on knowledge acquired from professional searchers; and the content of the knowledge base and the research needed to…

In Vitro Evaluation of a Program for Machine-Aided Indexing.
Peer reviewed Peer reviewed
Jacquemin, Christian; Daille, Beatrice; Royaute, Jean; Polanco, Xavier – Information Processing & Management, 2002
Presents the human evaluation of ILIAD, a program for machine-aided indexing that was designed to assist expert librarians in computer-aided indexing and document analysis. Topics include controlled indexing and free indexing; natural language and concept-based information retrieval; evaluation methodology; syntactic variations; and a comparison…

The Use of Semantic Links in Hypertext Information Retrieval.
Peer reviewed Peer reviewed
Frei, H. P.; Stieger, D. – Information Processing & Management, 1995
Highlights semantic links and shows how the semantic content of hypertext links can be used for information retrieval. Discussion includes indexing and retrieval algorithms that exploit link content and node content; retrieval strategies exploiting semantic links, including conventional retrieval and constrained spreading activation techniques;…

The Hybrid Application of an Inductive Learning Method and a Neural Network for Intelligent Information Retrieval.
Peer reviewed Peer reviewed
Cortez, Edwin M.; And Others – Information Processing & Management, 1995
Proposes an information retrieval system based on a hybrid model consisting of an inductive learning and neural network system. Evaluates the system's responses to incomplete queries and inconsistent indexing. Query terms, discriminant descriptors, and the American Documentation Institute's query and document titles used in the evaluation are…

Learned Vector-Space Models for Document Retrieval.
Peer reviewed Peer reviewed
Caid, William R.; And Others – Information Processing & Management, 1995
The Latent Semantic Indexing and MatchPlus systems examine similar contexts in which words appear and create representational models that capture the similarity of meaning of terms and then use the representation for retrieval. Text Retrieval Conference experiments using these systems demonstrate the computational feasibility of using…
