摘要

The present invention relates to knowledge repository systems for providing data that indicate the expertise, knowledge or experience of a user. A system for providing data that indicate the expertise, knowledge or experience of a user is proposed that comprises a semantic reasoning means (13) configured to analyze sensor data received from at least one sensor configured to generate sensor data by sensing an activity of a user (2) in order to infer personal knowledge data of the user (2) based on a predetermined domain ontology, wherein the personal knowledge data indicate a skill, expertise or experience of the user (2); a personal knowledge database (15) configured to store the inferred personal knowledge data of the user (2) in a semantic data model; and a search engine (14) means configured to perform a search within the personal knowledge database (15) to determine knowledgeable users whose personal knowledge data indicate that they have a desired skill or expertise.
