Gerard Salton

Gerard Salton (1927-1995) was a German-American computer scientist and information retrieval specialist.

Life

Gerard A. "Gerry" Salton was born on March 8, 1927 in Nuremberg, Germany and named Gerhard Anton Sahlmann. He came to the United States in 1947 and was naturalized in 1952. He received Bachelor's (1950) and Master's (1952) degrees in mathematics from Brooklyn College in New York city. He earned a Ph.D. from Harvard in applied mathematics in 1958 and taught there until 1965 when he joined Cornell University and co-founded its department of Computer Science. He died on August 28, 1995 in Ithaca, NY.

Contributions

Salton's team at Cornell developed the influential SMART (System for the Mechanical Analysis and Retrieval of Text) which he had initiated when he was at Harvard. SMART was an environment for evaluating retrieval systems.

SMART popularized the vector space model for weighted coordinate indexing using the words in the text of each document in a collection, excluding a stop list of very common or insignificant words. Each word is treated as a dimension a very highly dimensional graph. Each document in the collection is a treated as a vector with its position on each word dimension determined by the relative frequency of that word in that document. A query is expressed as a comparable graph and then each document's relevance to it is assessed by its graph's proximity to the query graph. [1]

Relative frequency was commonly refined by using term frequency–inverse document frequency (td-idf) whereby the relative frequency of a word in a document is weighted by the inverse relative frequency its presence in the collection as a whole so that rare words count for more than common words.[2]

Salton was editor-in-chief of the Communications of the ACM and the Journal of the ACM (1969 – 1972). He was an associate editor of the ACM Transactions on Information Systems and chaired the ACM Special Interest Group on Information Retrieval (SIGIR).
