Abstract: Hi! My name is Emil and I am a Teacher Bot. I was built to answer your initial questions about using KNIME Analytics Platform. Well, actually, I was built to point you to the right training materials to answer your questions about KNIME.
Puzzling together all the pieces to implement me wasn’t that difficult. All you need are:
A user interface - web or speech based - for you to ask questions
A text parser for me to understand
A brain to find the right training materials to answer your question
A user interface to send you the answer
A feedback option - nice to have but not a must - on whether my answer was of any help
The most complex part was, of course, my brain. Building my brain required: a clear definition of the problem, a labeled data set, a class ontology, and finally the training of a machine learning model. The labeled data set in particular was lacking. So, we relied on active learning to incrementally make my brain smarter over time. Some parts of the final architecture, such as understanding and resource searching, were deployed as microservices.
Bio: Rosaria Silipo has been mining data, big and small, since her master degree in 1992. She kept mining data throughout all her doctoral program, her postdoctoral program, and most of her following job positions. So many years of experience and passion for data analytics, data visualization, data manipulation, reporting, business intelligence, and KNIME tools, naturally led her to become a principal data scientist and an evangelist for data science at KNIME.
