The statistical method without background knowledge cannot reveal the semantic relations between words, and the thesaurus provides limited scope of words. Wikipedia, as a large corpus comprising semantic knowledgebase, becomes the new sources for measuring semantic similarity between words. Three new Wiki-based methods, WikiWalk, conceptual graph, and temporal semantic analysis are described in details. The future directions of this field continue to combine Wikipedia and other background information as complementary semantic resources. In addition, characterizing relatedness between words by performing a complex network analysis is also a future challenge.
