A Unified Model for Joint Chinese Word Segmentation and Dependency Parsing
share
Chinese word segmentation and dependency parsing are two fundamental tasks for Chinese natural language processing. The dependency parsing is defined on word-level, therefore word segmentation is the precondition of dependency parsing, which makes dependency parsing suffers from error propagation. In this paper, we propose a unified model to integrate Chinese word segmentation and dependency parsing. Different from previous joint models, our proposed model is a graph-based model and more concise, which results in fewer efforts of feature engineering. Our joint model achieves better performance than previous joint models. Our joint model achieves the state-of-the-art results in both Chinese word segmentation and dependency parsing.
