An integrated approach for measuring semantic similarity between words and sentences using web search engine

Semantic similarity measures play vital roles in Information Retrieval (IR) and Natural Language Processing (NLP). Despite the usefulness of semantic similarity measures in various applications, strongly measuring semantic similarity between two words remains a challenging task. Here, three semantic similarity measures have been proposed, that uses the information available on the web to measure similarity between words and sentences. The proposed method exploits page counts and text snippets returned by a web search engine. We develop indirect associations of words, in addition to direct for estimating their similarity. Evaluation results on different data sets shows that our methods outperform several competing methods.
