Susan Dumais is a Principal Researcher in the Adaptive Systems & Interaction Group of Microsoft Research.

Before joining Microsoft in 1997, Dumais was a researcher at Bellcore (now Telcordia Technologies), where she and her colleagues conducted research into what is now called the vocabulary problem in information retrieval. [cite journal

One implication of this work is that because the author of a document may use different vocabulary than someone searching for the document, traditional information retrieval methods will have limited success.

Dumais and the other Bellcore researchers then began investigating ways to build search systems that avoided the vocabulary problem. The result was their invention of Latent Semantic Indexing. [ cite journal
