The rise of the social web and its uptake by scholars has led to the creation of altmetrics, which are social web metrics for academic publications. These new metrics can, in theory, be used in an evaluative role, to give early estimates of the impact of publications or to give estimates of non-traditional types of impact. They can also be used as an information seeking aid: to help draw a digi...

The University of Michigan Digital Library is a large-scale confederation of software agents, providing library content and services to users and each other within a distributed network environment. Allocation of resources and activities to the various agents is determined through a market-based negotiation process, where agents tender ooers to buy or sell services , basic resources, and other ...

While tremendous progress has been made in developing parallel algorithms, there has not been as much success in developing language support for programming these parallel algorithms. The C++ Standard Template Library (STL) provides an opportunity for extending the concept of generic programming to the parallel realm. This paper discusses the basic requirements for extending STL to provide supp...

The 3G era brings new opportunities to telecommunications industry. This article introduces current situation of using network technology in digital library, in the 3G network, PTT has its own advantages so that it is feasible to be used in digital library. We highlight instance about digital library using PTT, and then solve the issue of context-aware transformation and use SIP-based system ar...

A course offering is a collection of learning objects composed together based on a syllabus. Syllabi define the contents of the course, as well as other information such as resources and assignments. Currently, there is no standard format for representing syllabi that can facilitate automatic processing of syllabi contents for various applications. In this paper, we report on the current practi...

Access control mechanisms are needed in almost every system nowadays to control what kind of access each user has to which resources and when. On the one hand access control systems need to be flexible to allow the definition of the access rules that are actually needed. But they must also be easy to administrate to prevent rules from being in place without the administrator realizing it. This ...

(ABSTRACT) The QUIZIT system has been developed to support adaptive and standard testing, along with automatic grading, record keeping, and test administration using the WWW as a delivery vehicle. We have applied QUIZIT in connection with our NSF-supported Education Infrastructure project on Interactive Learning with a Digital Library in Computer Science to help with evaluation in a master's le...
