A Customizable Recommendation engine for lms Challenge

Situation A UK based company in the field of blended learning wanted to expand their user base by providing a customizable application for generating a learning plan This application was lacking feature of integration with different LMS Older Adobe Flash based application had hardcoded contents and static UI resulting into complete dependency on software vendor for customizations

Need for generalized integration interface to support integration with various flavors of LMS. Need to have algorithmic approach to formulate reliable decision making process based on user interaction. Need to support desktop version of the application along with tracking of user activity. Need for administrative interface to create and support customizable contents.

Harbinger Solution Harbinger suggested automation of configuration of app, rules and contents of the app by providing web-based administrative interface. Designed decision tree based algorithms and implemented using JSON and Flex technologies to generate recommended learning plan according to user input.

Provided configurable wizard based web-interface to provide details such as LMS APIs and parameters, text and graphics.
