- An evaluation of retrieval effectiveness for a full-text document-retrieval system," with M. E. Maron. Communications of the ACM 28, no 3 (March 1985): 289-299. This evaluation of the retrieval performance of the STAIRS system that searched for words in an unedited full-text corpus is regarded as a classic in the information retrieval literature. Users who thought they were finding 70% of relevant documents (i.e., 70% recall) were in fact retrieving only about 20% because of variety in word usage. For example, a search for documents about accidents using the term "accident" would not retrieve a document if the politer term "incident" had been used. [1]
