John Maxwell is currently working on technologies for health care and social media.
John was the technical lead for PARC's XLE parser, which was one of the key enabling technologies used by Powerset for semantic search. Powerset, Inc. was acquired by Microsoft and became part of Bing. He also made significant contributions to the natural language technology that was licensed to Microlytics and to Inxight.
John joined PARC as an intern from MIT in 1978 as part of the Smalltalk group. His Master's thesis led to the first WYSIWYG music notation editor ("Mockingbird"), which appeared on the cover of Byte magazine in January 1984. John also helped develop the Cedar experimental programming environment before switching to computational linguistics.
