In this paper, we empirically demonstrate what we call the domain restriction hy- pothesis, claiming that semantically re- lated terms extracted from a corpus tend to be semantically coherent. We apply this hypothesis to define a post-processing module for the output of Espresso, a state of the art relation extraction system, show- ing that irrelevant and erroneous relations can be filtered out by our module, in- creasing the precision of the final output. Results are confirmed by both quantita- tive and qualitative analyses, showing that very high precision can be reached.
