Experiences with RFID-Based Interactive Learning in Museums
Tourism plays an important role in the economies of many countries.
Tourism can secure employment, foreign exchange earnings, investment and
regional development. To attract more tourists and local visitors, many
stakeholders such as natural parks, museums, art galleries, hotels and
restaurants provide personalised services to meet individual needs. With the
increasing number of tourists comes an increased demand for guides at
education-oriented leisure centers. Each provided needs unique way to present
their services. In this study, these educational leisure centres are coarsely
divided into art and science. This paper introduces the architecture of the
proposed guide system including a PDA-based recommendation guide for art
museums and an Radiofrequency identification-based interactive learning
system using collaborative filtering technology for science and engineering
education. Evaluations of the two systems reveal that the system inspires and
nurtures visitors’ interest in science and arts
Towards Privacy Compliant and Anytime Recommender Systems
The original publication is available at www.springerlink.comInternational audienceRecommendation technologies have traditionally been used in domains such as E-commerce and Web navigation to recommend resources to customers so as to help them to get the pertinent resources. Among the possible approaches is collaborative filtering that does not take into account the content of the resources: only the traces of usage of the resources are considered. State of the art models, such as sequential association-rules and Markov models, that can be used in the frame of privacy concerns, are usually studied in terms of performance, state space complexity and time complexity. Many of them have a large time complexity and require a long time to compute recommendations. However, there are domains of application of the models where recommendations may be required quickly. This paper focuses on the study of how these state of the art models can be adapted so as to be anytime. In that case recommendations can be proposed to the user whatever is the computation time available, the quality of the recommendations increases according to the computation time. We show that such models can be adapted so as to be anytime and we propose several strategies to compute recommendations iteratively. We also show that the computation time needed by these new models is not increased compared to classical ones; even so, it sometimes decreases
