This paper describes a fuzzy union based approach for automatically evaluating machine generated extract summaries. The proposed method represents every sentence within a machine generated summary as a fuzzy set. Sentences in the reference summary are assigned membership grades in each of these fuzzy sets using cosine distance measure. Finally Fuzzy union (s-norm operation) is used to compute an F-score measure. Max s-norm and Frank's s-norm operators are discussed and the advantages of using a modified Frank's s-norm operator for evaluating summaries is explained. The proposed evaluation method is compared to ROUGE evaluation system with some test cases.
