Grammar rule set is often used in natural language processing. Usually, rule set can only be gained in linguistics materials artificially. In this paper, through study on the using states of grammar rules in natural language processing, we propose a method, with using a typical way of data mining - mining association rules, of exploring Chinese grammar rules in real corpus environment. And we build...
A novel finite-state approach with the practical use of modal operators for Chinese partial parsing is presented in this paper. The traditional rule-based partial parsing approaches make use of regular grammar to approximate the context free or simplified context sensitive grammar with some loss of descriptive ability. Until now, how to solve the non-categorical problem within rule-based paradigm...
Cache is important for the performance of processor. With the multi-core developed, cache architecture for the performance of multi-core processor has begun to emerge. Through the result of running a test program for parallel computing obtains the phenomenon, this article analyses the reason of it occurred. It summarizes that the L2 cache architecture has an impact the performance of multi-core processor...
Among the solutions for stereo matching which is regarded as one fundamental topic in computer vision, methods based on regions can overcome the drawbacks of methods using points and lines as the features since regions can more exactly reflect the inherent properties of images processed. In this paper, we propose an efficient method to extract the local invariant region, in which the affine moment...
Hydrological parameters play important roles in designing new well. Dupuit formula and Theis formula are usually used to calculate hydrological parameters by insert numerical method. The precision of parameters is affected by insert numerical table and pumping test data of reference wells. Purpose of this paper is to study on utilizing these data efficiently. Firstly, database of water resource is...
