DNA sequencing by synthesis (SBS) on a solid surface during polymerase reaction offers a paradigm to decipher DNA sequences. We report here the construction of such a DNA sequencing system using molecular engineering approaches. In this approach, four nucleotides (A, C, G, T) are modified as reversible terminators by attaching a cleavable fluorophore to the(More)
Metaphor processing has been a heated topic in NLP. Cognitive properties of a word are important in metaphor understanding and generation. But data collected automatically tend to be reduced in both quantity and quality. This paper introduces CogBank a database of Chinese concepts and their associated cogni-tive properties. The database was constructed(More)
In this paper, we present a Chinese lexical taxonomy, a hierarchically organization of Chinese lexical classes of nouns, verbs and adjectives. We first describe the structure of this taxonomy and then present the methods we used to build it. The distinctive characteristics of this lexical taxonomy are: 1) we use definition frame to describe each lexical(More)
Either word sense classification or word sense clustering can not avoid this problem: what features people can get from word meaning that can be used as the tools employed for producing word sense ontology. In this paper, we present a lexical semantic-syntactic model to define and subcategorize a noun class—attribute noun class, by acquiring syntactic(More)
