A Framework for Automatic Web Service Discovery Based on Semantics and NLP Techniques

Table 1

Syntactic versus semantic approaches for Web services discovery.

	Syntactic-based approaches for WS discovery	Semantic-based approaches for WS discovery
Matchmaking technique	(i) A simple keyword-based search; (ii) Searching based on functional parameters; (ii) Searching based on syntax	(i) Exploit the semantic representation of concepts describing a Web Service and their relations in an ontology; (ii) Searching based on both functional and non-functional parameters
Advantages	(i) Simple and widely used technique.; (ii) Standards like UDDI exist	(i) Minimize the manual discovery and usage of Web service by allowing software agents to automatically and dynamically discover WSs; (ii) Pledge the automation of WS discovery process; (iii) Effective and reliable technique
Disadvantages	(i) Do not allow retrieval of Web Services with similar functionality; (ii) Not suited for automatic processing; (iii) Still requires human interaction	(i) More complex technique; (ii) Semantic tagging of Web services may be needed
