In this paper,various ways of integration of Chinese word segmentation and part-of-speech tagging, including the so-called true-integration and pseudo-integration,are tested and compared based on a test corpus consisting of 367,114 Chinese characters.A novel true-integration approach,named 'the divide-and-conquer integration',is originally *** experiments show that this true integration achieves 98.72%accuracy of word segmentation,95.65%accuracy of part-of-speech tagging,and 94.43%accuracy of word segmentation and part-of-speech tagging,outperforming all other kinds of combinations to some extent(though not very significant).The results demonstrate the potential for further improving the performance of Chinese word segmentation and part-of-speech tagging.

This paper proposes the notion of a greylevel difference classification algorithm in fractal image compression. Then an example of the greylevel difference classification algo rithm is given as an improvement of the quadrant greylevel and variance classification in the quadtree-based encoding algorithm. The algorithm incorporates the frequency feature in spatial analysis using the notion of average quadrant greylevel difference, leading to an enhancement in terms of encoding time, PSNR value and compression ratio.

An approach based on adaptive congestion control and adaptive error recovery with RS (Reed-Solomon) coding method is presented for efficient video transmission over the Internet. Featured by weighted moving average rate control and TCP-friendliness, AVSP, a novel adaptive video streaming protocol, is designed with adjustable rate control parameters so as to respond quickly to the QoS status fluctuation during video transmission over the Internet. Combined with congestion control policy, an adaptive RS coding error recovery scheme with variable parameters is presented to enhance the robustness of MPEG video transmission over the Internet with restriction to the total system bandwidth .

In this paper, the problem of checking a timed automaton for a Duration Cal-culus formula of the form Temporal Duration Property is addressed. It is shown that TemporalDuration Properties are in the class of discretisable real-time properties of Timed Automata,and an algorithm is given to solve the problem based on linear programming techniques andthe depth-first search method in the integral region graph of the automaton. The complexityof the algorithm is in the same class as that of the solution of the reachability problem of timedautomata.

Applications of the Hough Transform (HT) have been limited to small-size images for a long time. For large-size images, peak detection and line verification become much more time-consuming. Many HT-based line detectio...
