An evaluation of type-10 homograph discrimination at the semi-colon level in Roget's International Thesaurus
John R. Talburt, Donna M. Mooney · 1990
This paper reports the results of evaluating a large sample of the 23,858 type-10 homographs found in Roget's International Thesaurus (3rd Ed.) as defined by the Bryan Model of abstract thesauri, of which Roget's is an instantiation. According to the Bryan model, two different entries in a thesaurus that have the same spelling are homographs (semantically unrelated) if and only if they cannot be the endpoints of a sequence of entries called a type-10 chain. The Bryan definition of a type-10 homograph has not been tested thoroughly until recently because of the combinatorial complexity associated with a direct application of the definition to a large instantiation such as Roget's. However, in 1989, the authors were able to decompose Roget's in into its type-10 components, and as a result, generate all 23,858 type-10 homographs at the semi-colon category level.
