Abstract
Systems and method automatically collect training data from manually created semantic relations, automatically extract rules from the training data to produce extracted rules, and automatically characterize existing semantic relations in the training data based on co-occurrence of the extracted rules in the existing semantic relations. Such systems and methods automatically construct semantic relation topics based on the characterization of the existing semantic relations, and group instances of the training data into the semantic relation topics to detect new semantic relations.
