Combining Logical and Distributional Semantics
The Field of Distributional Semantics provides techniques for reasoning about the meanings of words and phrases based on usage statistics in large text corpora; however, these techniques typically fail to capture much of the logical structure of natural language. Purely logic-based approaches to natural language semantics, on the other hand, fail to capture many graded notions of word meaning. We are investigating methods to combine these two approaches to natural language semantics.
