An expert recommendation system using concept-based relevance discernment

An expert recommendation system using concept-based relevance discernment is proposed. This system processes the description of a technical topic as input and then finds engineers who have a high level of expertise in that area. The technique employed is an extended vector space model that locates both technical topics and engineers in the same multi-dimensional space, and then calculates their relevance. This system can also retrieve engineers or documents that are related to afield matching a given engineer's technical interests. Such a system can be expected to play the role of a person's professional network, and be a valuable tool for knowledge management among several organizations.
