Recall-Oriented Expert Search Using Relevance Feedback

The information engineering group at InIT has recently successfully concluded a CTI funded project. The project is called “expert-match” and has been conducted in cooperation with expert group ag, a professional recruitment and consulting business head-quartered in Zurich, Switzerland.

Expert group’s recruiting focus consists of staffing high-profile expert positions (e.g. specialized senior software engineers, senior management, IT architects). Usually, there are at most a handful of people qualified for a recruiting mandate within the relevant geographical region they operate in. The problem is further compounded by the fact that qualifications are rarely obvious, requiring insight into candidates’ former positions and overall skill sets. Exact matching of job descriptions with candidate profiles, such as in a database environment, is thus unlikely to find the desired experts. By implementing an information retrieval (IR) application, we were able to mitigate the problem. The application fully supports iterative searches, especially focussing on relevance feedback.
