Complex Event Processing refers to different mechanisms such as event correlation and event patterns detection for processing multiple events with the goal of inferring the complicated ones. While a simple event may provide trivial information, combining several of them can help in deriving more useful information. Detecting the complex events requires huge processing capability. The existing hardware...
An expert finding system enables individuals within a large organization to search for authoritative people in a certain area. Various approaches have been proposed to solve the problem of expert finding and most of them can be classified as either document model or candidate model. In this paper, we propose a novel strategy based on the document model to improve the performance of expert finding...
Agent organization is a set of agents to solve a problem together, it describes the relationship between agents and roles which agents taking. Firstly, this paper proposes the concept of stable matching in role assigning, and constitutes all the stable matching into a set F, then describes its properties. Secondly, considering the preference of role and agent, we construct a strong stable relations,...
The authors present a vehicle license plate recognition algorithm based on improved pattern matching. This algorithm is made up of two parts plate characters segmentation and characters recognition. In the license plate characters segmentation algorithm, dynamic thresholding is utilized to process license plates, and coordinate marking is utilized to divide character. In the characters recognizable...
Regular expressions are increasingly used in network security applications. Multiple regular expressions matching is one of the most important performance bottlenecks in those systems. This paper proposes a new hardware-based multiple regular-expressions matching architecture, called MRM, for network intrusion detection system. It shows that traditional algorithm, such as AC, has to face the serious...
Pattern matching and regular expression matching are all the critical components for content inspection based applications. But current regular expression matching algorithms or architecture cannot provide a perfect solution for whole matching problem. In some real network security applications, exact strings are the biggest part of rule set, and the second part is simple regular expressions (dot-star...
Pattern matching is one of the most important components for the content inspection based applications of network security, and it requires well designed algorithms and architectures to keep up with the increasing network speed. For most of the solutions, AC and its derivative algorithms are widely used. They are based on the DFA model but utilize large amount of memory because of so many transition...
