Abstract

The automatic interpretation of semantic relations between nominals is an important subproblem within natural language understanding applications and is an area of increasing interest. In this paper, we present the system we used to participate in the SemEval 2010 Task 8 Multi-Way Classification of Semantic Relations between Pairs of Nominals. Our system, based upon a Maximum Entropy classifier trained using a large number of boolean features, received the third highest score.
