Evaluation report of the use of Onto-Logging platform in the user site Deliverable ID: D8b Page : 26 of 110 Version: 1.0 Date: 27 january 2004 Status: Final Confid.: Public • The Ontology Editor for the creation of the ontologies for modelling a domain of application (domain ontologies, events ontologies, users ontology) in term of concepts and properties. • The Ontology & Knowledge Evaluators (OKE) provides the means to evaluate (and therefore to readjust) the authored ontologies. Other less technical elements will need also to be considered such as: • The effort and the expertise required to author complex ontologies. • The difficulty to make these ontologies evolve. • How to address the eventual conflicts that may occur when defining ontologies at the companies level (what happen if two departments have some diverging definition of a term?). 3.3.1.2 Elements associated to knowledge capitalization (Goal 2) Ontologging provides several tools that can be used for representing the knowledge of the organization: • The DUI (Distributed User Interface) is a tool that allows users (authors) to describe (using the Ontology “share vocabularies”) and enter new knowledge into the Knowledge Base. • The Office Connector allows users (authors) to enter knowledge directly from inside Microsoft office. The Office Connector is a visual basic extension of Microsoft Office, which can be used to annotate document being edited with the domain Ontology and enter the result in the Knowledge Base. • The user profile editor allows the users to define their profile (based on the user ontology that has been previously defined using the ontology editor). The User profile editor contributes to support the management of the tacit knowledge of the organization, and in particular the access of the knowledge that in only present in the people head. • The OKE provides the means to evaluate the knowledge stored in the Ontologging server, and therefore provide some indication useful for its reorganization. Non- technical elements will need also to be considered such as: • What is the overhead effort in the knowledge capitalization process? • Will formal roles (such as authors) have to be defined in the organization? • What are the incentive measures that will encourage people in the organization to capitalize knowledge, or to update their profile? • How to overcome resistance in adopting new knowledge capitalization practices? 3.3.1.3 Elements associated to knowledge searching and browsing (Goal 3)
Evaluation report of the use of Onto-Logging platform in the user site Deliverable ID: D8b Page : 27 of 110 Version: 1.0 Date: 27 january 2004 Status: Final Confid.: Public Ontologging provides several tools that can be used for searching and navigating the knowledge: • The Ontologging DUI provides the means for browsing and searching the knowledge that was stored in the Ontologging server. The underlying search engine is aware of the semantic of the knowledge, and in particular goes beyond the single keyword search. Besides, the inference engine (embedded in the DUI) allows querying of ontologies to discover information not explicitly present in the ontology. • The user profile editor provides a specialized tool to enter and maintain user information. This tool helps in particular to navigate the network of expertise (people) of the organization. Non- technical elements will need also to be considered such as: • What is the expertise necessary to exploit properly the technology? • Will training be necessary? • Will the value of Ontology techniques be visible enough (versus more traditional methods)? 3.3.1.4 Elements associated to knowledge sharing and exchange (Goal 4) Different tools in Ontologging that contributes to the facilitation of knowledge sharing in the organization, and knowledge exchange between the departments: • The Ontology Editor for the creation of the shared ontologies. Besides, Ontologging even provide some mechanisms for the collaborative authoring of ontologies (using agents for notification of conflicts). • The Ontology mapping tool, provides the means to reconcile ontologies that have been defined separately by different parts of the organization (different departments), allowing them to interoperate. • The user profile editor, by making more explicit people profile, can help the circulation of tacit knowledge (present in the people head) of the organization. Non- technical elements will need also to be considered such as: • Will the availability of tools be enough, and in particular strong signal from the top management will also be important in better inter-department communication? • What will be the incentive for people for sharing their knowledge, in particular for the sales people (what is it for me)? 3.3.2 Levels of evaluation for Ontologging. What could be evaluated Let’s provide for information a perspective of the evaluation according to the levels as it was described in the first part of the document.
