Exsys Corvid Core at Mac App Store analyse

Exsys Corvid Core is a tool for building and deploying online expert systems. It provides non-programmers a way to easily build interactive Web applications that capture the logic and processes used to solve problems and deliver it online to any Browser - even iPhones and iPads.

Organizations can now optimize their most valuable asset, expert knowledge, through powerful interactive Web-enabled knowledge automation expert systems. Online sessions emulate a conversation with a human expert asking focused questions and producing customized recommendations and advice.  The decision making skills of your top experts can now be made available to everyone.

Some of the most common application areas are:

Regulatory and Compliance Requirements
Diagnosing and Repairing Equipment and Processes
Web Self-Service Customer or Technical Support
Pre-Sales Advice for Prospects
Configuration of Complex Systems
Technical or Engineering "Best Practices"
Capturing Corporate Knowledge Before it is Lost
Smart Questionnaires

The powerful, proven Exsys Inference Engine supports probabilistic logic and backward chaining, making it easy to break even large problems into small sections that are automatically invoked when, and if, they are needed. Building a system with Corvid is more like explaining how a decision was made to another person than programming.

Corvid Core gives you everything you need to build high-value expert systems and put them online:

1. The Exsys Corvid Core development tool - based on the powerful, proven Exsys Corvid tool for Windows, but with a new user interface designed for the Mac

2. Both Java Applet and Servlet versions of the Exsys Runtime, that enable fielding the systems you build online. You are allowed to put these runtime programs on your server to field your systems. This is the same proven Exsys Inference Engine used to solve complex problems in industry, government and military systems. (Fielding systems with the servlet runtime allows them to run on iPhones and iPads)

3. Online tutorials to help you get started

4. An extensive, but very readable Corvid Core manual

5. Online sample systems, with details of how they were built and system files

6. An extensive support expert system, built with Corvid Core, to solve most common issues in installing and running systems.


Exsys Inc. has been in the expert system development tool business since 1983. For over 30 years, Exsys tools have been used to build tens of thousands of expert systems in business, industry, government and military. Exsys systems have been used for a vast range of complex problems including jet aircraft diagnostics, diagnosing complex equipment, helping Fortune 100 companies be at maximum productivity, and assuring complex regulations are followed.

Exsys Corvid Core on the Mac brings this experience to Mac developers for the first time, and at a much lower price than ever before.

Users considering Exsys Corvid Core can try it out by downloading the FREE Exsys Corvid Core LITE version from the App Store. This is the same a Corvid Core, but limited to only allowing 15 variables and 25 rules. This is enough to run the online Exsys Corvid Core tutorials and learn how to build Exsys expert systems. The systems started with the Lite version can be continued with the full Corvid Core version later. The full version has no limits on the number of variables or rules in a system.

It’s the Real McCoy

When I heard that Exsys Corvid was going to sell a Mac version of its expert system shell for $150, I was totally stunned and frankly still am. My stunned condition did not arise from any grief about having laid out thousands (and I mean lots of thousands) of dollars for their PC version a few years ago, but rather from the fact that expert systems were now truly going to be coming to the masses. There has been so much talk in the legal profession and other professions that deal with specialized knowledge (like human resources) about the need for automation and change and so little action other than on the highest levels. For me, the key was whether this was a true “core” version of Exsys Corvid. So I bought a Mac and have been working with the Core program ever since. I write this review to tell you this program is the real McCoy. It is an expert system that you can start using tomorrow to put together mind-boggling applications. While expert system technology used to be reserved for a few well-heeled and visionary firms, it is now available to the rest of us. I am anxious to find out if all the talk in my own profession of law has been so much hot air. Just one piece of reality to finish up with. Software developers, and Exsys Corvid is no exception, like to tell us that learning and using their programs is “easy”, sort of like your Lego-experienced kid could spot your Mac at the kitchen table, sit down and develop a system or two before bedtime. I am a klutz at technical stuff and so I may not be in the best position to judge, but “easy”? Do not believe it. Doable? Yes, for sure. Building an expert system is not computer programming but it requires patience and as-you-go learning of knowledge-engineering techniques. Is it fun? Wait until you build a truly useful knowledge delivery system and then answer that question. I think I know what you will say. All thumbs up for this product and, at this price, a truly stunning (that word again) opportunity to get to work on the future.
