The advent of web applications that provide automated user assistance as well as the evolution in using conversational programs, has led to the development of new directions in online customer support. By taking into consideration the fact that quick and flexible online assistance is nowadays crucial for engaging customers and after identifying the current gaps especially in public services, we decided to develop a conversational chatbot system based on public services for a greek web portal called ,diadikasies.gr, in order to help citizens find easily the desired service. Another critical objective of our thesis, was to annotate several public services from this web portal using a european standard called C.P.S.V(CorePublicServiceVocabulary)and develop the chatbot system to retrieve these semantic data on real time in order to operate appropriately.
