A Personalized System for Conversational Recommendations
Searching for and making decisions about information is becoming increasingly
difficult as the amount of information and number of choices increases.
Recommendation systems help users find items of interest of a particular type,
such as movies or restaurants, but are still somewhat awkward to use. Our
solution is to take advantage of the complementary strengths of personalized
recommendation systems and dialogue systems, creating personalized aides. We
present a system -- the Adaptive Place Advisor -- that treats item selection as
an interactive, conversational process, with the program inquiring about item
attributes and the user responding. Individual, long-term user preferences are
unobtrusively obtained in the course of normal recommendation dialogues and
used to direct future conversations with the same user. We present a novel user
model that influences both item search and the questions asked during a
conversation. We demonstrate the effectiveness of our system in significantly
reducing the time and number of interactions required to find a satisfactory
item, as compared to a control group of users interacting with a non-adaptive
version of the system

Knowledge Cartography: Software tools and mapping techniques
Knowledge Cartography is the discipline of mapping intellectual landscapes.The focus of this book is on the process by which manually crafting interactive, hypertextual maps clarifies one’s own understanding, as well as communicating it.The authors see mapping software as a set of visual tools for reading and writing in a networked age. In an information ocean, the primary challenge is to find meaningful patterns around which we can weave plausible narratives. Maps of concepts, discussions and arguments make the connections between ideas tangible and disputable.
With 17 chapters from the leading researchers and practitioners, the reader will find the current state–of-the-art in the field. Part 1 focuses on educational applications in schools and universities, before Part 2 turns to applications in professional communitie
Conversational Agents, Humorous Act Construction, and Social Intelligence
Humans use humour to ease communication problems in human-human interaction and \ud
in a similar way humour can be used to solve communication problems that arise\ud
with human-computer interaction. We discuss the role of embodied conversational\ud
agents in human-computer interaction and we have observations on the generation\ud
of humorous acts and on the appropriateness of displaying them by embodied\ud
conversational agents in order to smoothen, when necessary, their interactions\ud
with a human partner. The humorous acts we consider are generated spontaneously.\ud
They are the product of an appraisal of the conversational situation and the\ud
possibility to generate a humorous act from the elements that make up this\ud
conversational situation, in particular the interaction history of the\ud
conversational partners
