Synchronous collaborative navigation is a form of social navigation where users virtually share a web browser. In this paper, we present a symmetric, proxy-based architecture where each user can take the lead and guide others in visiting web sites, without the need for a special browser or other software. We show how we have applied this scheme to a(More)
In this paper we propose an approach to lightweight acquisition, sharing and annotation of experience-based corpora via mobile devices. Corpora acquisition is the crucial and often costly process in speech and language science and engineering. To address this problem, we have built a system for creating a location based corpora annotated with multi-media(More)
Early estimation of the size of a software product is extremely important. In this paper we analyze two software packages developed by a CMM level 3 software firm. We study if any property of analysis objects can be used to infer the size of the final code in an object-oriented environment. In both cases we find the number of methods well correlated with(More)
Proper reuse of learning objects depends both on the amount and quality of attached semantic metadata such as " learning objective " ', " related concept " , etc. Manually expressing such metadata is a time consuming and expensive task.. Here we present an approach based on a probabilistic model, which through the automatic classification of learning(More)
