Modified Publication and Matching Method for Sensor Observation Service
Xie Xiao-ya · Computer Technology and Development · 2015
At present,when the SPS faces a large number of SOS,it is unable to help users find the SOS that is function-matching effectively. In this paper,improve the method for SOS publication and matching based on SPS2. 0 standard. The expanding and semantic tagging for the WSDL of SOS description document and the observed task submitted by user is carried out by SAWSDL specification firstly,which can enhance the capacity of the service description and discovery efficiency. Then the checking of compatibility to the service behavior constraints in the service matching stage is accomplished,not only can reduce the matching resources' cost but also ensure matching accuracy. Finally,based on SOS characteristics and the weight of each attribute value,the service matching is finished to reduce the complexity of the matching. The experimental results showthat the approach,compared with traditional SPS,have evident improvement in recall and precision.
