Abstract: A method for creating and maintaining ontologies. The method includes transmitting a two dimensional table to a requestor. The table includes domain concepts and semantic primitives related to a domain. A data value in the table at an intersection of a domain concept and a semantic primitive indicates that the domain concept is characterized by the semantic primitive. A command to modify the table is received from the requestor. The table is updated in response to the command. The updated table is stored as an ontology.

Abstract: A method for building a new case or enhancing an established case for inclusion in a case base from log entries. The method includes identifying a current log entry, the current log entry including a status of a current diagnostic process. The method also includes identifying a previous log entry, the previous log entry including a status of either a current diagnostic process or a previous diagnostic process. A determination is made about whether the previous log entry is related to the current log entry. An inquiry is generated to create a link between the previous log entry and the current log entry in response to a determination that the previous log entry is related to the current log entry. The method further includes receiving a request to create a link in response to the inquiry. A link is created between the previous log entry and the current log entry in response to the request resulting in the case.
