Exsys Inc Features

Trying to automate expert decision-making?

Exsys Inc. features, centered around Exsys CORVID, empower domain experts to build intelligent advisory applications without coding. Here are the five main Exsys Inc. features that can transform how your organization leverages knowledge.

1. Rule-Based Reasoning and Logic Blocks

Complex decisions are hard to standardize, right?

Capturing nuanced human expertise in a structured, actionable format often feels impossible. This can lead to inconsistent advice or missed opportunities.

Exsys CORVID lets you define “If/Then” rules within “Logic Blocks,” mimicking how experts think. From my testing, organizing rules into blocks simplifies complex logic, making it easy to manage and update. This feature effectively translates tacit knowledge into a clear, usable system.

This means you can finally codify your organization’s best practices, ensuring consistent decision-making across the board.

2. Variable Types and Confidence Factors

Does your system only give “yes” or “no” answers?

Real-world problems rarely have single, absolute solutions, yet many systems lack the nuance to reflect this. This forces you into rigid recommendations.

This feature supports diverse variable types, including crucial “Confidence Variables” that assign probability to recommendations. What I love about this approach is the ability to provide ranked, probabilistic answers, much like a human expert would. It’s truly powerful for complex scenarios.

So, you can deliver more realistic and helpful advice, guiding users through choices with varying degrees of certainty.

3. User Interface Customization and Dynamic HTML Generation

Struggling with clunky, generic system interfaces?

A poor user experience can deter adoption, even if the underlying logic is brilliant. Your valuable expert system might just go unused.

CORVID offers extensive UI customization, letting you control fonts, colors, and positioning for a professional look. Here’s what I found: the dynamic HTML generation capability allows your expert system to seamlessly integrate with your existing website’s branding. No HTML expertise needed.

This means you can deploy an advisory system that truly feels like an integral part of your organization’s digital presence.

4. Integration with External Data Sources

Is your expert system an isolated island of knowledge?

An expert system’s true power lies in its ability to leverage existing organizational data, not just static rules. Lack of integration means manual data entry or outdated advice.

Exsys CORVID excels at connecting to databases via SQL, XML data via XPath, and even custom Java code. This is where Exsys Inc. shines: it ensures your expert systems are data-rich, pulling in information from all corners of your business.

The result is your system always has the most current information, providing accurate advice without relying on siloed data.

5. Deployment Flexibility

Worried about how to deliver your expert system to users?

Finding the right deployment method can be a headache, whether it’s standalone, web-based, or integrated into existing apps. Limited options can restrict user access.

Systems built with CORVID can be deployed as standalone Java applications, or over the web using Servlet or Applet Runtimes. This flexibility means you can choose the best delivery method for your specific users and IT infrastructure. I found this super helpful for reaching diverse audiences.

So, as a manager, you can confidently roll out your expert system in the most accessible format, maximizing its impact.

These Exsys Inc. features combine to create a robust expert system development platform, allowing organizations to automate and disseminate critical decision-making processes.

Exsys Inc Pricing
