A New Framework for Textual Information Mining Over Parse Trees
Authors:
Hamid Mousavi, Deirdre Kerr and Markus R. Iseli
This paper introduces a new text mining framework using a tree-based Linguistic Query Language, called LQL. The framework generates more than one parse tree for each sentence using a probabilistic parser, and annotates each node of these parse trees with main-parts information. The main-parts can be specialized for different domains based on a user-generated list of concepts. Using main-parts-annotated parse trees for a given textual dataset, the system can efficiently answer individual queries as well as mine the text for a given set of queries. The framework also has the ability to support grammatical ambiguity through probabilistic rules and linguistic exceptions in order to increase the quality of the extracted information.
