Common Services researched by Service Science have four major provision modes: web page mode, local client mode, web service mode and cloud service mode. Currently the most common used is Web Service mode. And now most Web Services provided by every Service Provider access and discovery strategy is still based on keyword search's UDDI. Services returned to users often can't be called. This paper will raise a new Web Service access and discovery strategy which combines with Search Engine technology and Semantic Web technology. Search engine technology provides a search capability based on lexical analysis and grammar analysis while Semantic Web technology provides a matching and scoring capability based on semantic information. Search result lists returned to users will sort from higher score to lower score. This Web Service discovery strategy will improve service's recall ratio and precision and it is very practical in engineering.
