Name the two dimension of Knowledge Retrieval
The Gartner group presents the KR function along two dimensions:
a) A semantic and
b) A collaboration dimension.
In the former, linguistic analysis, thesauri, dictionaries, semantic networks, clustering (categorisation/table of contents) are used to create an organisation's Concept Yellow Pages. These are used as organisational knowledge maps (conceptual and physical). The proposed techniques consist of both algorithmic and ontology generation and usage. The Collaboration dimension's goal is to achieve "value recommendations" identified by experts and trust advisers, community building activities, and collaborative filters. Domain experts who hold valuable tacit knowledge can be explicitly identified and consulted for critical decisions
