(English Abstract)
In this paper, we propose an information extraction system that can automatically extract user intended key syntax, by analyzing the dependency parse of a sentence. Previous Open Information Extraction studies extract two related arguments based on a verb to structuralize information, from massive data in unsupervised methods. However, users may be unable to extract key syntax accordingly, from a sentence without a verb or a sentence with various arguments. To solve this problem, this system first splits a sentence into an appropriate length to enhance the accuracy of analysis and incorporates dependency relations between words using a dependency parser. Then, we defined four extraction rules from the most basic sentence structures and built a system to extract meaningful chunking from predefined rules. Consequently, with a rule-based approach, users can freely add or modify extraction rules and derive key syntax from any type of a document. We experimented with Wikipedia data and the system achieved 33% more accuracy than DepOE, another OIE system that applies a dependency parser. As a result of the experiment, the system we propose enables easy analyses of written text and will be useful in analyzing various texts in the future.
