“…The integrative methodology proposed in [19] is used. This methodology has already successfully been applied in different domains: (a) Intensive Care Units [37], to develop an ontology-based system for monitoring patients; (b) biological application domains [20]; (c) biomedical domains such as ''diagnosis and plagues in tomatoes" and "diagnosis and diseases caused by protozoa" [17,18] with an academic purpose. The framework was used for integrating ontologies in the second and third domains and for managing intelligent alarms in the Intensive Care Unit application domain.…”

“…Our integration approach follows our work in Ref. 29 which produced promising results in a number of domains. The integrated model/ontology is evolved as a result of a sequence of integration steps of model components from many experts, and resolving inconsistencies between them.…”

In any modelling activity, a framework to determine the maturity of a developed model before its use is highly advantageous. Such a framework would save modellers expensive time in many areas of information systems. It would also lower the risk of users relying on an incomplete or inaccurate model. In this paper, we develop a framework which uses internal inconsistencies as a quantitative indicator for estimating the completeness and correctness of a model as it is cooperatively evolved. Whilst internal inconsistencies are due to bad fit between different parts of a model, we argue that they are also correlated with how the evolved model fits with the "world". This argument underpins our framework to evaluate integrated models.Contributions of this paper are three folds: firstly, it presents a theoretically grounded framework for integrating models. We extend an existing incremental modelling framework, NRDR, which represents multiple hierarchical restricted domains (MHRD), with automatic concept integration to allow NRDR to deal with multiple experts. Secondly, we couple this integration framework with a theoretically grounded monitoring process to assess the quality of the cooperatively developed model. Thirdly, 45 Int. J. Coop. Info.

Beydoun et al.we illustrate an initial empirical study of our evaluation and integration framework in a computer hardware administration domain. We capture and integrate computer hardware models from several experts and we use our modelling evaluation framework to evaluate the resultant cooperative model.

The design and implementation of an ontology-based Web retrieval (ONTOWEB) system is described; ONTOWEB allows the semantic search of the Web resources of international organizations such as the World Bank and the Organisation for Economic Co-operation and Development (OECD). A firm's knowledge management project is introduced first, followed by a description of the ONTOWEB system's design, implementation, and evaluation. The ONTOWEB system has two components: databases and an ontology-based search engine. The ontology-based search engine is a tool used to query the information that has been loaded into the database. Last, to evaluate the system, an experiment was conducted to compare the performance of the proposed system with that of Internet search engines in terms of relevance and search time. This study shows that ontologies can be used not only to improve precision, but also to reduce the search time. Because of the expense of annotating resources, the domains that contain the most valuable knowledge, such as the medical and the business sectors, are prime areas for future ontology applications.
