Following up from a previous blog post about integrating Drools with the Open Prediction Service, in this new post we want to share the current results from another exploration work: this time integrating Drools with research on Transparent Machine Learning by IBM. Introduction Transparency is a key requirement in many business sectors, from FSI (FinancialRead more →

Comparison of a JSON array based approach vs Jackson Inheritance Annotations Introduction: “Kogito is a next generation business automation toolkit that originates from well known Open Source projects Drools (for business rules) and jBPM (for business processes). Kogito aims at providing another approach to business automation where the main message is to expose your businessRead more →
This short tutorial walks you through the configuration and deployment of a simple Drools serverless application, including autoscaling with scale to zero, thanks to Kogito, Quarkus, OpenShift Serverless with Kubernetes and Knative! Step 1: Drools app creation with code.quarkus.io To generate the application as shown in the video, you can use this link: https://code.quarkus.io/?e=org.kie.kogito%3Akogito-quarkus-decisions&e=resteasy-jackson&e=kubernetes&e=container-image-jib TheRead more →
Introduction to TrustyAI and Drools Explainability is a crucial aspect in modern AI and decision services work; recent laws entitle any person subject to automated decisions to explanations of the intuition behind said decisions. Moreover, people are more likely to trust the decisions of explained models compared to unexplained models (Kim et al., 2022). Furthermore,Read more →
In the past few weeks we have been working hard on redesigning the architecture of Drools the rules engine and the rest of our ecosystem of runtime engines. In this blog post I want to focus a bit on the refactoring of the KnowledgeBuilder, a core component of the build infrastructure of the v6-v7 APIs.Read more →
We sometimes see questions regarding Drools version upgrade. Most of those questions are about how to change the old API usage in Drools 5 or 6. In this article, I’m going to guide how to change your code to work with the latest Drools version (7.70.0.Final as of now). API If you are using oldRead more →
Drawing a real case DMN asset may become a time-consuming activity. In some domains, the possible types involved in DMN logic can explode into dozens or even hundreds of possible involved objects. Although a well-designed UI can support users to define your domain object type in a simpler and faster way possible, other alternative strategiesRead more →
In this blog post we’re going to explore an integration between the Drools DMN Engine and another open source project from IBM: "Open Prediction Service" (OPS). Introduction Integrating symbolic AIs (rule engines, KRR, etc) with Machine Learning predictive models is an effective strategy to achieve pragmatical, and often more eXplainable, AI solutions. We have alsoRead more →
Defeasible reasoning [1] is a field of interest in both Philosophy and Computer Science (the subdiscipline of Artificial Intelligence (AI)). While the philosophical history of the field goes back to Aristotle, AI has only shown interest in it over the last 40 years. What is called nonmonotonic reasoning in AI is roughly the same asRead more →
