14. The system according to claim 13 , said processor removing redundant ones of said semantic relation topics.
13. A system comprising: a processor; and a non-transitory data storage device in communication with said processor, said non-transitory data storage device maintaining manually created semantic relations, said processor automatically collecting training data from said manually created semantic relations, said processor automatically extracting rules from said training data to produce extracted rules, said extracting rules comprising automatically removing noisy data from said semantic relations by filtering out ones of rules that do not occur in said training data, said processor automatically characterizing existing semantic relations in said training data based on co-occurrence of said extracted rules in said existing semantic relations, said processor automatically constructing semantic relation topics based on said characterizing of said existing semantic relations, and said processor grouping instances of said training data into said semantic relation topics to detect new semantic relations.
