It is meaningful to recommend appropriate works to a researcher. One important consideration is the relatedness to one's interests. Although it can be expressed by one's query on an academic dataset, there often exists some semantic ambiguity in relatedness computation that are caused by personalized vocabularies of authors and queriers. Another considered aspect is the quality of a publication, which...
We analytically model an unreliable opportunistic spectrum sharing (OSS) system through a queueing theoretic framework. Both initiating secondary users and ongoing secondary users sense the channels and perform appropriate activities. The sensing errors from either initiating or ongoing secondary users cause false alarm and misdetection events, which may impose different types of call collision results...
In order to solve the implementation efficiency problem of the network information system security policy, an improved object-oriented Rete algorithm and network structure model are proposed. The control methods of the nodes and tokens in the matching algorithm with the pattern join order are studied, that core idea is to use the separate matches to construct matching tree dynamically based on content...
It applies a rule engine design scheme with dynamic programming algorithm and optimal policy in financial management system. The scheme adopts backward reasoning method, when the facts and rules change in a small way, the results of constant parts are kept by the algorithm, and it just needs to calculate the changing parts. Thus, the massive repeated calculating workload can be reduced, which enhances...
Workflow management systems (WfMS) allow organizations to streamline and automate business processes and reengineer their structure. One important requirement for this type of system is the management and computation of the quality of service (QoS) of processes and workflows. Currently, a range of Web processes and workflow languages exist. Each language can be characterized by the set of patterns...
