This paper proposes an hybrid recommender system, InLinx, that combine content analysis and the development of virtual clusters of students and of didactical sources providing facilities to use the huge amount of digital information according to the student's personal requirements and interests. The paper proposes novel methods for information management,(More)
The clinical, radiological, and pathological features of nine cases of intracranial parenchymal schwannoma are described. The clinical course in four patients 23 years of age or younger mirrored the indolent nature of this neoplasm. Imaging studies included computerized tomography in eight patients and magnetic resonance imaging in three. The lesions were(More)
This paper discusses a general framework for knowledge acquisition and management in an intelligent tutoring system. This system is based on " Learning by performance errors " theory stating that in a given domain knowledge there is a set of constraints that must be satisfied in order to provide the correct solution to the problem. This paper addresses the(More)
In the last years Intelligent Tutoring Systems have been a very successful way for improving learning experience. Many issues must be addressed until this technology can be defined mature. One of the main problems within the Intelligent Tutoring Systems is the process of contents authoring: knowledge acquisition and manipulation process is a difficult task(More)
In this paper we discuss the problems of developing Web-based Adaptive Hypermedia (AH) for engineering education using Extensible Markup Language (XML). AH systems are capable of altering the presentation of the content of the hypermedia on the basis of a dynamic understanding of the individual user [5]. The user profile can be collected in a user model,(More)
BACKGROUND A clinicopathologic study of 70 cases of cellular schwannoma was performed to assess their distribution, response to therapy, and rate of recurrence relative to modern prognostic indicators. METHODS Seventy-one cellular schwannomas from 70 patients were retrieved from the files of the Mayo Clinic Tissue Registry. The significance of mitotic(More)
The experience from years of development and use, the advance of technology, and the development of authoring tools for questions and tests has resulted in a sophisticated, computer based assessment system. However, there is still a lot of room for further development. Some of the current ideas for development are discussed in the remainder of this work. A(More)
