Deduction over Mixed-Level Logic Representations for Text Passage Retrieval
arXiv:cs/9912009 · doi:10.1109/TAI.1996.560480
Abstract
A system is described that uses a mixed-level representation of (part of) meaning of natural language documents (based on standard Horn Clause Logic) and a variable-depth search strategy that distinguishes between the different levels of abstraction in the knowledge representation to locate specific passages in the documents. Mixed-level representations as well as variable-depth search strategies are applicable in fields outside that of NLP.
