Karen Ida Boalth Sparck Jones was a self-taught programmer and pioneering British computer and information scientist responsible for the concept of inverse document frequency, a technique underlying most modern search engines. Combining statistics and linguistics in information retrieval and natural language processing, she was also an advocate for women in computer science. The Karen Sparck Jones Award has recognized outstanding research in her fields annually since 2008.

What did Karen Spärck Jones contribute to the search engines we use today?
She introduced inverse document frequency term weighting, now standard in modern systems including the search engines of the Web.
Karen Spärck Jones introduced inverse document frequency term weighting in the 1960s, when she started working on information retrieval. The University of Cambridge obituary describes it as a technique that has been adopted as standard in modern systems, including the search engines of the Web, and that has spread to other language processing applications. She later worked with Stephen Robertson to establish the value of relevance weighting for terms, a step in the development of a probabilistic model of retrieval.

She was an advocate for women in computer science, her slogan being, "Computing is too important to be left to men." In 2019, The New York Times published her belated obituary in its series Overlooked, calling her "a pioneer of computer science for work combining statistics and linguistics, and an advocate for women in the field." From 2008, to recognise her achievements in the fields of information retrieval (IR) and natural language processing (NLP), the Karen Spärck Jones Award is awarded annually to a recipient for outstanding research in one or both of her fields.
