The ELIZA project is an AI customer support module, which automates parts of the customer support functions by leveraging machine learning functions. It integrates into existing data sources like whitepapers, user activity, forums, FAQ pages and others. Collected data is stored into a big data/Hadoop cluster and processed. The results are then used to implement various AI use cases. The system learns continuously from user generated data and activity and is able to improve the quality of its answers.
The technical solution was implemented using Hortonworks big data cluster. Data ingest layer was implemented with Apache NIFI, Kafka. Data access layer uses Java, Tomcat, and HBase. Perimeter security
