....decision is correct within a specific context. Context in knowledge acquisition is generally considered either before the building of the system or during the use of the system. The former is the main approach that is followed in the knowledge acquisition community. For example, Walther and al. [55] describe a context definition language call MODEL for the PROTEGE II system. MODEL is a metatool architecture that associates an explicit data model with every reusable module in the tool s libraries. Such a data model describes the externally visible aspects of every module, and defines a ....

....an extension to SQL, called Context SQL (C SQL) which allows the receivers import context to be dynamically instantiated in an SQL like query. Context SQL provides a vehicle for users who are interested in modifying their import contexts dynamically as queries are formulated. Walther et al. [55] use the PROTEGE II system as a metatool for constructing taskspecific expert system shells. The system associates each method with an ontology that defines the context of that method. All external interaction between the method and the world during the method assembly are a mapping of knowledge ....

....language, to represent the domain knowledge. Ontolingua also eases the translation of ontologies, which adds to the portability of PSMs. Therefore, we have a tool to formalize and operationalize PSMs. 8 Another work whose goal s research are similar with ours is Prot eg e II system [17, 12] where a complete environment for modeling KBSs from reusable components is defined. The significant advantage of Prot eg e II is the automatic generation of knowledge acquisition tools specific for each PSMs. They also suggest the use of Ontolingua to define portable ontologies, but it is not ....

....may use one to three problem solving methods. That is why it is rare for an existing problem solving method to match specific application needs without modification. Researchers are studying ways in which to decompose the generic problem solving methods into finer grained, primitive modules [4, 33, 38 44] . These modules are sometimes called mechanisms , and they are employed in the service of methods. For example, the skeletal plan refinement method involves a subtask called plan recognition. Several mechanisms are possible for solving this task. Researchers are planning to build libraries of ....

....system that uses context to provide system directed dialogues to enable controlled steps in the direction of mixed initiative dialogue. An example of the use of context for providing better reasoning is found in PROTG II System, a meta tool for constructing task specific expert system shells [33] The application of context to plan recognition has been explored by Johnson [22] who presented a system called REACT, used for training operators of the communication links in NASA s Deep Space Network (DSN) The systems described above paint a general picture of the existing research. They ....

A long term objective of such work is to enable libraries of reusable knowledge components and knowledge based services that can be invoked over networks. We believe the success of these efforts depends on the development of an engineering discipline for ontology design, akin to software ....
