Extracting instances of a given target relation from a given Web page corpus seems to be the basic work to exploit nearly endless source of knowledge which provided by the World Wide Web. Supervised learning requires a large amount of labeled data, but the data labeling process can be expensive and time consuming. In this paper we present a kernel-based weakly supervised machine learning algorithm...
A parse tree contains rich syntactic structured information, and the structured features have been proved effective in relation extraction. In this paper, we proposed another way to efficiently utilize structured features but in a weakly learning way. Co-training algorithm was chosen by us, the structured features were set to be one view of it, and the flat features were set to be the other. Through...
Extracting instances of a given target relation from a given Web page corpus seems to be the basic work to exploit nearly endless source of knowledge which provided by the World Wide Web. In this paper, we present an automated system which could extract instances of an arbitrary given binary relation from Chinese Web documents in domain of football games. Different syntactic sources are combined by...
In order to correctly recognize the current state of equipment for preventing equipment farther degradation and occurrence of failure, a new method of equipment degradation state recognition based on wavelet correlation feature scale entropy(WCFSE) and hidden semi-Markov models (HSMM ) was proposed. Firstly, the gathered vibration signal of equipment was processed by the way of the wavelet transform...
