Abstract

Open Information Extraction (OpenIE) has been studied extensively, targeting at extracting structured information from free text. In this paper, we work on a novel OpenIE problem defined as Domain-specified Attribute-Value Extraction: Given a text corpus and a domain Knowledge Base (KB) with a number of domain attributes and corresponding attribute values, the task is to extend the KB by identifying more domain attributes and attribute values from the text corpus. Existing solutions adopted from the other OpenIE problems rely heavily on either using deep linguistic parsing or identifying effective lexical patterns. However, linguistic parsing does not always work well especially on short texts, while learning lexical patterns is too strict to reach a high extraction recall. In this paper, we propose an effective graph-based iterative extraction approach based on the cooccurrence between attribute terms and attribute value terms in the same sentences. Our experiments performed on two large real world data collections demonstrate that our method outperforms state-of-the-art approaches in reaching 10% higher extraction precision and recall.
