Brian Sawyer is an American software developer, screenwriter, producer, and director known for creating VP-Expert, a pioneering expert system shell, co-authoring technical books on visual programming tools, and his extensive work in television and film writing, particularly in the holiday and mystery genres.[1][2]
Early career and software development
editSawyer began his career during the personal computing revolution of the 1980s, focusing on artificial intelligence and expert systems technology.[3] He developed VP-Expert, an expert system shell published by Paperback Software that became the best-selling product of its kind for personal computers.[4]
VP-Expert
editVP-Expert, created by Sawyer, was a rule-based expert system development tool that allowed users to build knowledge-based applications without extensive programming expertise.[5] The software featured:[4]
- Backward chaining for goal-driven reasoning
- IF-THEN rule structures for knowledge representation
- An explanation facility to make decision processes transparent
- User-friendly interface accessible to non-programmers
By 1990, VP-Expert had sold over 120,000 copies worldwide and was used by major organizations including DuPont, Kodak, and the Wharton School of Business.[6] The software found applications across diverse fields including business, finance, engineering, healthcare, and education.[7]
Sawyer's work on VP-Expert helped democratize artificial intelligence tools, making expert system creation accessible to businesses and researchers with limited programming backgrounds.[8] One notable application was "Wines on Disk," a wine recommendation system developed by Anthony Dias Blue using the VP-Expert framework.[9]
ObjectVision collaboration
editIn 1990, Sawyer co-authored "ObjectVision: A Graphical Programming Tool for Object-oriented Applications" with management consultant Paul Harmon.[10][11] The book documented ObjectVision, a forms-based programming language and environment for Windows 3.x developed by Borland.[12] ObjectVision used decision trees rather than traditional programming languages, making application development accessible to non-programmers and supporting various database formats including Paradox, dBASE, and BTrieve.[13]
Early game development
editPrior to his expert system work, Sawyer developed "Dungeon" (1979), an early computer role-playing game that has been recognized by gaming historians for its technical innovations and influence on the genre.[14]
