Abstract
A table corpus processing server identifies concepts within enterprise domain data. The table corpus processing server is configured to iteratively group values in a table corpus based on co-occurrence statistics to produce a candidate hierarchical tree. The candidate hierarchical tree is then summarized by selecting nodes that can best “describe” the original corpus, which leads to a small tree that often corresponds to desired concept hierarchies. The table corpus processing server employs a parallel dynamic programming approach that allows the disclosed embodiments to scale with amount of enterprise domain data being analyzed.
