Semantic relatedness, or its inverse, seman- tic distance, measures the degree of close- ness between two pieces of text determined by their meaning. Related work typically mea- sures semantics based on a sparse knowledge base such as WordNet1 or CYC that requires intensive manual efforts to build and main- tain. Other work is based on the Brown cor- pus, or more recently, Wikipedia. Wikipedia- based measures, however, typically do not take into account the rapid growth of that re- source, which exponentially increases the time to prepare and query the knowledge base. Fur- thermore, the generalized knowledge domain may be difficult to adapt to a specific domain. To address these problems, this paper pro- poses a domain-specific semantic relatedness measure based on part of Wikipedia that a...
