information into buckets in order to speed up search. He did not only consider handling numbers more efficiently. He was applying his concepts to text as well. Luhn’s methods were improved by computer scientists decades after his inventions. Today, hashing algorithms are essential for many applications such as textual tools, cloud services, data-intensive research and cryptography among numerous other uses. It is surprising that his name and contributions to information handling are largely forgotten. Two of Luhn's greatest achievements are the idea for an SDI system and the KWIC method of indexing. Today's SDI systems owe a great deal to a 1958 paper by Luhn, "A Business Intelligence System", which described an "automatic method to provide current awareness services to scientists and engineers" who needed help to cope with the rapid post-war growth of scientific and technical literature. Luhn apparently coined the term business intelligence in that paper. References External links Class Lecture Notes: H. P.
