Abstract: Methods for knowledge management which may be performed within a data processing system. In one method, documents held in a database are displayed. Usage information relating to each document in the database is accumulated, a usage score is determined based on that information and a relevance value is assigned. The relevance value is then used to sort the documents and a list is presented to the user. Preferably, knowledge related concepts are defined and a profile representing a knowledge requirement of the user is established. A profile score may then be calculated and included in the relevance value. A user score, based on a subjective assessment of the document, may also be included in the relevance value.
