Abstract: A conversational agent, capable to have a "sense of humor" is
presented. The agent can both generate humorous sentences and recognize
humoristic expressions introduced by the user during the dialogue. EHeBby is an
entertainment oriented conversational agent implemented using the ALICE
framework embedded into an Yahoo! Messenger client. It is characterized by two
areas: a rational, rule-based area and an evocative area. The first one is
based on well founded techniques of computational humor and a standard AIML KB.
The second one is based on a conceptual space, automatically induced by a
corpus of funny documents, where KB items and user sentences are mapped. This
area emulates an associative/evocative behavior of the conversational agent,
making her more attractive. EHeBby includes also an avatar that changes the
face expression according to humoristic content of the dialogue.
