Espresso: leveraging generic patterns for automatically harvesting semantic relations

ACL '06: Proceedings of the 21st International Conference on Computational Linguistics and the 44th annual meeting of the ACL, : 113--120, 2006.
Authors: Patrick Pantel and Marco Pennacchiotti

Description: Espresso
Tags: extraction
Abstract: In this paper, we present Espresso, a weakly-supervised, general-purpose, and accurate algorithm for harvesting semantic relations. The main contributions are: i) a method for exploiting generic patterns by filtering incorrect instances using the Web; and ii) a principled measure of pattern and instance reliability enabling the filtering algorithm. We present an empirical comparison of Espresso with various state of the art systems, on different size and genre corpora, on extracting various general and specific relations. Experimental results show that our exploitation of generic patterns substantially increases system recall with small effect on overall precision.
