Hi there, I was working the last 5 days in a simple project to demonstrate how we can use Drools Expert, Drools Fusion and jBPM5 to coordinate the content that it’s being displayed in an application. Some of the related topics that I’m trying to cover here in this post are: User behavioral patterns, Recommendation and Suggestions mechanism that are influenced by the User interactions, Marketing Campaigns selections, Trends analysis, etc. If anyone out there is doing the same thing or trying to solve a similar problem, it would be nice to start discussions around these topics. I will also be sharing some presentations around these topics that includes very simple introductions about the Drools project to be able to share these content with people that doesn’t know how the project can be used.
This post is about a project that I’ve started 5 days ago to demonstrate how we can create a model around visual components that are being displayed to an user and then analyze and decide in real time different actions based on the user interaction.
Some of the initial considerations that I have in mind when I start working on it were related to web applications, but for time restrictions to show some useful results I’ve created a simple Swing Application. As you may know, Swing provide an event based framework to create Desktop Applications in the Java World. I plug Drools Expert, Fusion and jBPM5 in the back to analyze the user interaction and express declaratively how to react to different patterns of interactions.
The next step in the future will be adapt this mini framework to a very simple GWT application, to leverage the advantage of web technologies to gather concurrent users behavioral patterns.
The following video just show the application working. You can see a main page with a set of custom Visual Components with some meta data. For demo purposes I’ve choose to relate a product to each visual component. Based on this meta model we can write rules to analyze and react to different interaction patterns.
As the video shows, we can also add new Visual Components on demand and apply new rules to that user session.
Simple Use Cases
When I was designing this simple PoC I select simple use cases to create a generic model that can be used for multi purpose analysis.
The following slides introduce the project and describe the 4 main use cases that I want to demonstrate using this PoC.
As you may notice all the use cases use the temporal dimension to define a situation. This is something that can be skipped if we can define logical situation around what is being displayed to the user in a particular point in time. In the previous figures I use yellow lines to describe the events that are being generated by the user interaction and in red the one that doesn’t happen. This is extremely important, because detecting events that don’t happen is usually a complicated feature to implement using imperative programming languages. Here with Drools Fusion you get it for free 🙂
The project source code can be downloaded from github -> https://github.com/Salaboy/smart-content-selection
Please remember that this is just PoC. Esteban helps me to make it cleaner and more presentable in the UI side and in the code side, but this is just the effort of 5 days of work.
The project itself it’s under the Apache License V2 so it can be extended and used for general purpose. If you have feedback about it or if you are interested and wanna contribute to be able to get something useful, please let me know and we can collaborate each other to build something on top of it.
As always, feedback is more than welcome!
