What is Natural Language Generation

The development of intelligent guides for a museum is an important theme of research entailing a variety of challenging aspects. Intelligent guides are based on the idea that information presentation should take into account the context of the individual, in the first place the position of the visitor, but also other information that the system can infer about his background, interests and attitude during the visit, and tailor presentation of information accordingly. PEACH was a large project devoted to cultural heritage appreciation that combined aspects of basic research and applied research specific for the development of a complex prototype. The chapter provides a state of the art of intelligent museum guides, a presentation of PEACH and several of the involved technologies, and an assessment of some of the outstanding further challenges.
