Academics have relied heavily on search engines to identify and locate research manuscripts that are related to their research areas. Many of the early information retrieval systems and technologies were developed while catering for librarians to help them sift through books and proceedings, followed by recent online academic search engines such as Google Scholar and Microsoft Academic Search. In...
A rat robot is a type of animal robots, where an animal is connected to a machine system via a brain-computer interface. Electrical stimuli can be generated by the machine system and delivered to the animal's brain to control its behavior. The sensory capacity and flexible motion ability of rat robots highlight their potential advantages over mechanical robots. However, most existing rat robots require...
Brain-computer interfaces are attracting much attention in the field of pervasive computing. It makes possible to directly transfer a subjects decision to another. In this paper, we develop a motor brain-computer-brain system, which allows human mind to drive a rat robot in a navigation environment. Neural signals from an EEG headset are transmitted wirelessly to a computer, then the decoded neural...
Aiming at deficiencies of existing knowledge resources management systems, we designed a new collaborative knowledge construction system for massive knowledge resources. By collaborative knowledge building in the following three phases: acquisition of knowledge factors, generation of the local extended topic maps and integration of global extended topic map, we realized a conjunction of concept level...
By research on topic map standard, the extended topic map (ETM) is proposed as a novel model for organization and management of the massive knowledge resources in e-learning. Based on the model, an extended topic map toolkit is designed and implemented, which allows for operations as exploration, search, consistency check and etc. The ETM toolkit not only provides learners with visual navigation and...
