Abstract
This paper presents a novel algorithm of extracting keywords from single-sentence natural language queries in English. The process involves applying a series of rules to a parsed query in order to pick out potential keywords based on part-of-speech and the surrounding phrase structure. A supervised machine learning method is also explored in order to find suitable rules, which has shown promising results when cross-validated with various training sets.
