Expert System Experts.

Expert System Experts



For 25 years Exsys Inc has focused exclusively on knowledge automation expert systems and in creating development tools that are powerful enough to handle real-world problems, but still easy for non-programmers to quickly master. Applications built with Exsys tools are in use worldwide by business, government and military users. Exsys was one of the first companies to create expert system development tools, the first to create and effective way to deliver interactive expert systems over the Web, and now the first to put a powerful knowledge automation inference engine under Adobe Flash.



When Exsys Inc started in 1983, expert systems were viewed as an exotic solution to decision-making, more at home in Hollywood than in reality. In the 25 years since then, the rule based expert system approach to automating complex decision-making tasks has proven to be by far the most effective, reliable and proven way to capture and deliver the logic and process of human experts to solve complex problems. If you ask an expert how they made a particular decision, in most cases, they will explain it in “If/Then” style rules. This is the natural way that people think and describe how they made a decision. It is the same way that rules are written in Exsys Corvid. The development environment makes it easy to write rules, using just English (or whatever language you prefer) and algebra. The rules can be read and understood without learning a complex programming syntax. Corvid makes it easy to structure the rules so that they are complete and cover all scenarios. In fact, building a system is a very effective way to present the expert with all the possible cases and capture a much wider scope of their knowledge.



In addition to rules, there must be an Inference Engine to process them. The inference Engine is what drives the end user interaction. It determines what information is needed to reach a conclusion, whether the needed information can be derived from lower level rules and what to ask of the user. It processes user input to analyze the data, including using probabilistic rules to consider the “likelihood” of various options, and in the end, generates recommendations and advice based on the same logic and process as the human expert that built the system. The inference engine drives an interactive session with the user, asking questions as needed in a focused way that emulates a conversation with a human expert.



There is “If/Then” syntax in virtually every computer language, but it is the Inference Engine that gives rule based expert systems their special capabilities. The Exsys Inference Engine is the result of 25 years of enhancement, refinement and application to real-world problems. It is extensively used and proven in thousands of industry, government and military applications. The Exsys Corvid Inference Engine is Java based making it portable and ideal for Web applications.



The user interface of an application is the third important factor is system development. Exsys makes it easy to build and field system with the Exsys Applet Runtime. The look and feel of the system can be easily set from within the Corvid development environment. For more complex interfaces, the Exsys Servlet Runtime can be used, allowing interface screens to be designed using HTML. For the most complex systems, the user interface can be designed using the multimedia capability of Adobe Flash integrated with the Exsys Servlet Runtime.



Exsys development tools have been used to build tens of thousands of expert systems and are the most proven environment you can use for your expert system project.
