A Web Service Clustering Method Based on Semantic Similarity and Multidimensional Scaling Analysis

Algorithm 1

Preprocessing of a service description document.

	Input: D, T, α
	Output: PD (PD is initialized to empty)
	Begin:
	FOR each tag in T do:
	flag ⟵ 0;
	FOR each word in D do:
	IF WordNet.similarity (tag, word) >α do:
	PD.add (word);
	flag ⟵ 1;
	ENDIF
	ENDFOR
	IF flag = 0 do:
	PD.add (tag);
	ENDIF
	ENDFOR
	RETURN PD;
	END
