Human-Computer Interaction using Natural Language . An Application in the Medical Treatment Domain

The effective information retrieval, along with the comprehensive dialogue systems response, happen to be of great importance in medical applications domain, where the precision of information is critical and users are usually inexperienced and unwilling to participate in long, tiring interactions. The use of natural language is a promising idea because it is direct, natural for the humans and does not need any special training. Our work presents a natural language interaction system, developed by Hellenic partners and utilized with success in the medical domain. Experimental results and comparisons with other methods tabulate improvement in time response as well as in the correctness of the answer. The evaluation of the model was done using a group of 20 persons of different specialties (medical stuff-doctors-computer users-students) which were already trained about how to use the system and each one supplied 25 different questions.
