Salton, Gerard was born on March 8, 1927 in Nuremberg, Germany. Son of Rudolf and Elisabeth (Tuchmann) Salton.
He received a Bachelor"s (1950) and Master"s (1952) degree in mathematics from Brooklyn College, and a Doctor of Philosophy from Harvard in Applied Mathematics in 1958, the last of Howard Aiken"s doctoral students, and taught there until 1965, when he joined Cornell University and co-founded its department of Computer Science.
Salton was perhaps the leading computer scientist working in the field of information retrieval during his time, and "the father of information retrieval". His group at Cornell developed the Self-Monitoring, Analysis and Reporting Technology Information Retrieval System, which he initiated when he was at Harvard.
Salton was perhaps most well known for developing the now widely used vector space model for Information Retrieval. In this model, both documents and queries are represented as vectors of term counts, and the similarity between a document and a query is given by the cosine between the term vector and the document vector.
In this paper, he also introduced TF-Israel Defense Forces, or term-frequency-inverse-document frequency, a model in which the score of a term in a document is the ratio of the number of terms in that document divided by the frequency of the number of documents in which that term occurs.
(The concept of inverse document frequency, a measure of specificity, had been introduced in 1972 by Karen Sparck-Jones) Later in life, he became interested in automatic text summarization and analysis, as well as automatic hypertext generation. He published over 150 research articles and 5 books during his life.
Salton was editor-in-chief of the Communications of the Association for Computing Machinery (ACM) and the Journal of the Association for Computing Machinery (ACM), and chaired Special Interest Group on Information Retrieval (SIGIR). He was an associate editor of the Association for Computing Machinery (ACM) Transactions on Information Systems.
