Suitable employees wanted? Find them with semantic techniques

More and more companies are going to use Internet for their job procurement process, i.e. to search for job seekers and publish open positions. However, common search techniques based on classical keyword search fail to match job seekers with job offers since particular (over-constraint) queries return no answers and search engines are unable to semantically relax such queries. In this paper we briefly describe an approach where explicitly defined rewriting rules are used to reformulate the query in a controlled way and explain the architecture of our job portal extension giving an impression about the relaxation process.
