To study the problem empirically, we also carry out experiments with a real ontology galen [RZStGC] containing close to 3000 concepts.

.... hypermedia, Conceptual querying, Tourism information systems, User requirements, Ethnographic studies 1 INTRODUCTION The TourisT project is developing a prototype conceptual hypermedia tourism information system, using GRAIL, a terminological logic devised at the University of Manchester [1], to maintain the conceptual model. A primary concern of the work is to develop a system which assists the tourist seeking information. The project has thus used the results of ethnographic studies, carried out in tourist information centres, to inform the structure and content of the conceptual ....

....the validity of medical data entered. It was quite possible to, for example, enter a code for a part of the body in a symptom list. These problems suggested the use of a more structured representation language for both medical knowledge and content selection rules. GRAIL, used by the GALEN project [2] seemed a good choice, being designed as a general knowledge representation language, yet tailored to the needs of medical terminology. It: Allows multiple inheritance, and allows new concepts to be composed from existing ones. Provides a constrained, well defined yet flexible language, with ....

.... and how it is being treated) The medical knowledge base was constructed based on the organisation of concepts in the Read coding scheme (used by the National Health Service in the UK) but has since been modified to use the GRAIL representation language from the GALEN medical terminology project [47]. Figure 4 gives an example text from the original system (words in bold font can be clicked on for further information) Both Piglit and Migraine use simple surface realisation based on selecting from human authored templates (e.g. The symptoms of Disease X are Symptoms Y ) and filling in with ....

....depends on the coding scheme used. In a system (such as ICD 9) where a separate code is given for every distinguishable concept, then a simple mapping of code to preferred English phrase may be possible. But in more complex compositional schemes, such as that used in the GALEN terminology server [47], generating the appropriate English phrase for a compositional concept becomes more difficult [58, 59] However, although the generation of noun phrases is more complex, the approach can pay off if multilingual output is required [57] While the 1997 version of the UMLS [46] correlates ....

....of the European Galen project the Medical Informatics Group at Manchester University have built a large concept model representing knowledge about medical terminology. The model is intended to promote sharing and re use of medical data by acting as a flexible and extensible classification schema [40, 39]. In existing applications this function is often served by controlled vocabularies , of which more than 20 are currently in use. These vocabularies or coding schemes are often very large and thus both difficult and costly to build and maintain. Moreover, in spite of the fact that many schemes ....

The paper deals primarily with the architecture and motivation for a terminology server, and where possible avoids detailed ....

....relationship can be used to organise queries automatically and views, hence supporting data exploration and query optimisation. Description Logics have been used in a wide variety of applications including the representation of complex schemas for cars [30] software management [8] and medicine [27], data archaeology [6] mediation between heterogeneous data stores [2] and database querying [16] However, interacting with Description Logic implementations can often prove difficult. In the past, solutions involved embedding the logic in large monolithic systems with all the attached problems ....

Introduction There are an increasing number of efforts to develop formal representations of medical terminology and concepts [1 6]. These efforts are part of a general move to provide a common infrastructure to re use clinical information and to integrate the disparate applications in the healthcare environment e.g. medical records, decision support, information retrieval, and management information systems [1, 5, 6] ....

.... concepts [1 6] These efforts are part of a general move to provide a common infrastructure to re use clinical information and to integrate the disparate applications in the healthcare environment e.g. medical records, decision support, information retrieval, and management information systems [1, 5, 6]. Integration is only possible if there is a common language which can be shared amongst applications for representing what clinical users have said and done. Even without the requirement for integration, more expressive representations are a requirement for many single applications, e.g. 11, ....
