In this paper, we introduce our recent work on Chinese HPSG grammar development through treebank conversion. By manually defining grammatical constraints and annotation rules, we convert the bracketing trees in the Penn Chinese Treebank (CTB) to be an HPSG treebank. Then, a large-scale lexicon is automatically extracted from the HPSG treebank. Experimental(More)
BACKGROUND A variety of methods for prediction of peptide binding to major histocompatibility complex (MHC) have been proposed. These methods are based on binding motifs, binding matrices, hidden Markov models (HMM), or artificial neural networks (ANN). There has been little prior work on the comparative analysis of these methods. MATERIALS AND METHODS We(More)
This paper proposes an approach using large scale case structures, which are automatically constructed from both a small tagged corpus and a large raw corpus , to improve Chinese dependency parsing. The case structure proposed in this paper has two characteristics: (1) it relaxes the predicate of a case structure to be all types of words which behaves as a(More)
This paper discusses the difficulties in Chinese deep parsing, by comparing the accuracy of a Chinese HPSG parser to the accuracy of an English HPSG parser and the commonly used Chinese syntactic parsers. Analysis reveals that deep parsing for Chinese is more challenging than for English, due to the shortage of syntactic constraints of Chinese verbs, the(More)
This paper proposes an approach for bilingual dictionary extraction from comparable corpora. The proposed approach is based on the observation that a word and its translation share similar dependency relations. Experimental results using 250 randomly selected translation pairs prove that the proposed approach significantly outperforms the traditional(More)
In this paper, we proposed a method to recognize the handwriting of several Chinese characters or even a full sentence simultaneously. With a common single Chinese character recognition engine and a language model, the whole recognition process is divided into two optimization processes. The first is to find the best grouping scheme to segment a plurality(More)
Cable robots have seen considerable recent interest ensuing from their ability to combine a large workspace with significant payload capacity. However, the cables can apply forces to the end-effector only when they are in tension, and thus form a subclass of control problems requiring unilateral control inputs. Furthermore, actuation redundancy occurs when(More)
