VP-Expert is an artificial intelligence development tool that gained popularity in the 1980s and early 1990s. Published by Paperback Software, VP-Expert was designed to facilitate the creation of rule-based expert systems, primarily for applications in business and industry.[1][2] VP-Expert was written by Brian Sawyer.[3][4][5]
Features
[edit]VP-Expert incorporated several features that supported the development and deployment of expert systems:[6]
- Rule-Based Reasoning: VP-Expert utilized a rule-based inference engine to process knowledge represented as IF-THEN rules.[6]
- Backward Chaining: The system primarily employed backward chaining, a goal-driven reasoning strategy, to deduce conclusions or solutions based on the given facts and rules.[6]
- User Interface: VP-Expert offered a user-friendly interface for knowledge acquisition, simplifying the process of defining rules, facts, and goals.[7]
- Explanation Facility: The system was capable of providing explanations for its reasoning, enhancing user understanding of how conclusions were reached.[7]
Applications
[edit]VP-Expert found applications across various domains,[8][9][10] including:
- Environmental Analysis: Researchers used VP-Expert to develop a knowledge-based system for analyzing the impact of particulate matter air pollution on human health.[11]
- Engineering Design: VP-Expert was utilized in the creation of a prototype expert system to assist in fishway design.[12]
- Aviation Management: The tool was employed to develop an expert system aimed at maximizing airport capacity while adhering to noise-mitigation plans.[13]
These examples illustrate its versatility in addressing diverse problem-solving needs. VP-Expert quickly gained market share in the expert system development tool sector, particularly in academic and small to medium-sized business environments. By 1990, it had become one of the most widely used expert system shells in educational institutions, with an estimated installation base of over 50,000 copies worldwide.[7]
Limitations
[edit]While VP-Expert offered certain advantages, it also had limitations:
- Scalability: Its rule-based approach could become challenging to manage for large and complex knowledge bases.[7]
- Knowledge Acquisition Bottleneck: The process of eliciting and encoding knowledge from experts could be time-consuming and difficult. [7]
