Abstract: The fundamental problem of service resources covers the discovery of semantic service resources in need. The paper puts forward a novel service resources (including Web services, Grid services) discovery algorithm based semantic description of information, that combines the textual matching approach to achieve large scale service resources discovery quickly and accurately. Experimental results show that the algorithm for semantic service resources discovery achieves better query precision than traditional service resource discovery systems. When the extensive service resources query are combined with accurate service resources matching, the discovery algorithm con achieve better efficiency.
