Contract Statements Knowledge Service for Chatbots [article]

Boris Ruf, Matteo Sammarco, Marcin Detyniecki
2019 arXiv   pre-print
However, constructing a formal model which captures the full scope of a contract proves difficult due to the overall complexity its set of rules represent.  ...  Towards conversational agents that are capable of handling more complex questions on contractual conditions, formalizing contract statements in a machine readable way is crucial.  ...  Conversational agents can query the rules via API which allows for seamless integration with any chatbot framework.  ...
