VisiRule Expert System Software

Rapidly Deliver Innovative Products & Services

VisiRule is an easy-to-use Low-Code No-Code AI tool for subject matter experts, like lawyers, tax advisors, engineers, to rapidly define and deliver intelligent advice and troubleshooting guides using decision tree flowcharts. VisiRule can also incorporate rules discovered from data using AI machine learning via VisiRule FastChart.

​

VisiRule builds systems to handle those common but non-trivial enquiries and computations that people have to spend time on, and customers want solving, in a cost-effective way. This frees staff to focus on the more difficult tasks, and empowers clients with instant access to high-quality advice anywhere, anytime. Use cases include problem triage with recommended prescriptive actions plus document generation. You can enable users to access expert knowledge and obtain personalised advice online via Intelligent ChatBots or automated processes.

​

VisiRule combines visual diagramming, executable code generation to support automated decisioning. This eliminates the need to encode know-how into some incomprehensible “computer gobbledygook”. Authors can keep current their online advice using a visual model as regulations, best practice and the people change. VisiRule allows authors to capture, evaluate, refine and deploy their expertise.

Simplify Complexity with VisiRule

Simple

VisiRule's visual editor is easy-to-use and enables the rapid creation and testing of complex systems with minimal training required.

​

Smart

VisiRule helps you draw a viable decision model as it knows which links are appropriate based on the current context.

​

Safe

VisiRule uses a robust logic engine for a high degree of consistency.

​

Scalable

VisiRule combines lean AI technology with modern cloud-based servers & containers to provide a scalable and affordable solution.

Easy to Create

Programming via Flow Charts

VisiRule is a visual tool which combines smart diagramming, AI reasoning, Excel-like calculations and document automation. Like Visio and MindMap, you simply draw a model, but one you can execute in active applications.

​

Visual Knowledge

Visual knowledge is much easier to understand, validate and maintain than text. VisiRule’s programming via flow charting permits rapid prototyping and supports the accurate capture and shared understanding of knowledge.

​

Low-Code No-Code Development

VisiRule is an intuitive Low-Code No-Code tool. You can learn how to draw decision models in minutes. Read about No Code and Lawyers here.

Easy to Generate

VisiRule includes a powerful document generation engine to automate document output in various formats such as text, PDF, XML, HTML and RTF. 

​

By associating suitably tagged document templates, i.e. boilerplates, VisiRule can produce high-quality documents using the answers gathered in the session. Not limited to inserting simple values, VisiRule can combine complex logic with conditional text selection and insertion.​

Easy to Deploy

JavaScript XML Delivery

VisiRule charts can be delivered client-side using XML and a dedicated JavaScript engine to ask the questions and collate the answers. Users can even revisit and re-answer questions in a highly responsive and convenient way.

​

Custom HTML Presentation

Questions can be presented in house-style simply by editing the style sheets associated with the various assets, brands and icons. 

Put your brand in their pocket! 

Automated Delivery

VisiRule automatically constructs the questionnaire, the Business Rules and calculations directly from the chart itself.

​

Connected & Embedded Delivery

VisiRule can be be delivered using interactive forms and/or via embedded, connected services using REST and JSON.

Easy to Share

VisiRule provides a clear, visual way of representing decision logic - one that business users can understand.​ 

Expertise can be shared across a wide group to help form a consensus. Afterall, a picture is worth 1,000 words. 

VisiRule's advanced code generation capability allows the model to be immediately executed and tested. All the knowledge contained within a chart can be exported as a picture to help document the process.

Easy to Explain

Justify Reasoning

Explainable AI means VisiRule can explain itself. Each visitor's execution path can be explained in terms of HOW, WHAT and WHY. Contrast this to neural nets which are black boxes and can NOT explain their reasoning.

​

Export Answers

User sessions, including all answers, calculations and conclusions, are logged and can be distributed via email or pushed into a database.

​

Audit Knowledge

VisiRule includes a Truth Table Generator which enumerates all possible paths to provide an audit of the knowledge in the chart.

Easy to Maintain

Update

As your chart gets used and the legal or business context changes, you can amend, revise and enhance its logic, and so ensure that it is up-to-date.

​

Analytics

You can use VisiRule Analytics to help understand how a chart is being used and adapt it to the changing environment in which it operates.

​

Knowledge is Precious

VisiRule can help your company capture and retain valuable knowledge which can be shared via XML or as pictures.

Four Quadrants of Reasoning

The knowledge in VisiRule can come from historical data using Machine Learning, or from human experts or both. VisiRule FastChart enables VisiRule to access predictive models to create an initial VisiRule chart. Read how the Titanic dataset was used in such a way.

​

VisiRule decision tree flow charts can be delivered interactively or data-driven. In hybrid delivery mode, some questions are asked, and others answered using existing data, web services or IoT streams.

Expert System Software Technology

Multi-Layered Architecture

VisiRule is flagship of a Low-Code No-Code No-Cliff AI platform comprising:

• Flex - a Low-Code, expert system software tool 

• Prolog - a powerful No-Cliff AI programming language.

Flex Expert System

VisiRule generates code in terms of Flex, LPA's powerful rules-based expert system shell toolkit which supports both forwards and backward chaining rules with an English-like Knowledge Specification Language (KSL).

LPA Prolog

Prolog is a well proven AI programming language with pattern matching and logical inference. Prolog provides a robust foundation for the LPA stack. The LPA implementation includes a dedicated string datatype which provides the basis for the suite of VisiRule NLU/NLP functions.
