An XML schema-based similarity algorithm is brought forward. Elements in XML schema are the main and the similarity among elements is the major components of schemas similarity. The algorithm takes full account the structure and semantics of elements. Experimental results reveal the proposed method is very accurately and reliably predicts the similarity. In the mean while, it reduces the complexity...
The performance analysis of parallel system is critical for tuning, optimizing and algorithm modifying of parallel program. A formal modeling method based on TCPN is proposed in this paper, which makes it possible to organize a complicated parallel system as a set of hierarchical modules and includes a time concept to represent the time taken to execute events and further analyze the performance of...
In this paper, the concept of the adaptive multi-mode interactive interface based on embedded equipments is proposed and its implementation on digital STB is also brought forward, accompanying with the concrete design of the program step and the implementation details of the key component. The adaptive multi-mode interactive interface effectually improves the performance of human-computer interaction...
Correctness and performance are the principal requirement of a parallel system. Due to the complicated and uncertainty, it is necessary to model it. A hierarchical TCPN model proposed in this paper can investigate on various levels of abstraction and analyze concerning performance, functional validity and correctness. It describes the parallel program and the resources respectively to bring less effect...
Schema extracting for XML is broadly used in the field of data storing, query optimization and heterogeneous data integration. This paper presents a method based on node relative path for extracting XML schema. The new approach finishes extracting schema by scanning XML document once-over and extracting nodes and relative paths. It can overcome the defects including circles and lack of sides. This...
A similarity algorithm based on weighted hierarchical structure of XML document is brought forward. The algorithm can calculate the similarity among XML documents efficiently according to hierarchical structure. It can be powerful enough to distinguish the similar structural documents. Experimental results prove that the algorithm reduces the complexity and has fairly high performance. The approach...
