Abstract

This paper presents a deterministic parsing algorithm for projective dependency grammar. In a bottom-up way the algorithm finds the local optimum dynamically. A constraint procedure is made to use more structure information. The algorithm parses sentences in linear time and labeling is integrated with the parsing. This parser achieves 63.29% labeled attachment score on the average in CoNLL-X Shared Task.
