This paper provide a brief survey of semantic similarity including semantic similarity between concepts and semantic textual similarity. We classify methods of semantic similarity between into four categories based on background information resource used and classify methods of semantic textual similarity into four categories too. As a basic methodology of text related research and applications, semantic similarity measure is often used in online social network analysis. This survey introduces how similarity computation methods assist in many aspects of social network analysis.
