In this paper, we present a three-step multilingual dependency parser based on a deterministic shift-reduce parsing algorithm. Different from last year, we separate the root-parsing strategy as sequential labeling task and try to link the neighbor word dependences via a near neighbor parsing. The outputs of the root and neighbor parsers were encoded as(More)
Phrase pattern recognition (phrase chunking) refers to automatic approaches for identifying predefined phrase structures in a stream of text. Support vector machines (SVMs)-based methods had shown excellent performance in many sequential text pattern recognition tasks such as protein name finding, and noun phrase (NP)-chunking. Even though they yield very(More)
In this paper, we present our statistical-based opinion analysis system for NTCIR-MOAT track this year. Our method involves two different approaches: (1) the machine learning-based prototype system (on the basis of support vector machines (SVMs)) and (2) stochastic estimation of the character-level of words. The former were the real applications of(More)
In Chinese, most of the language processing starts from word segmentation and part-of-speech (POS) tagging. These two steps tokenize the word from a sequence of characters and predict the syntactic labels for each segmented word. In this paper , we present two distinct sequential tagging models for the above two tasks. The first word segmentation model was(More)
Data-driven learning based on shift reduce parsing algorithms has emerged dependency parsing and shown excellent performance to many Tree-banks. In this paper, we investigate the extension of those methods while considerably improved the runtime and training time efficiency via L 2-SVMs. We also present several properties and constraints to enhance the(More)
—In this paper, we present a robust passage retrieval algorithm to extend the conventional text question answering (Q/A) to videos. Users interact with our videoQ/A system through natural language queries, while the top-ranked passage fragments with associated video clips are returned as answers. We compare our method with five of the high-performance(More)
Several phrase chunkers have been proposed over the past few years. Some state-of-the-art chunkers achieved better performance via integrating external resources, e.g., parsers and additional training data, or combining multiple learners. However, in many languages and domains, such external materials are not easily available and the combination of multiple(More)
