Microblog, as a way of online communication, can generate large amounts of information in a very short period. Therefore, how to retrieve the latest relevant information becomes a hot research area. Different from traditional information retrieval (IR), the microblog retrieval emphasizes fresh contents of the information. In order to solve this problem, we extend the traditional IR methods by t...

This paper proposes an efficient Tracking method for velocity control of an electro-hydraulic servo system (EHSS) in the presence of flow nonlinearities and internal friction. The tracking method controller is a kind of feedback error learning structure. In the proposed method, the Feedback Error Learning (FEL) algorithm is used to control the velocity. There is no need to compute the system ja...

This paper describes the validation study of our software that uses combined webcam and microphone data for real-time, continuous, unobtrusive emotion recognition as part of our FILTWAM framework. FILTWAM aims at deploying a real time multimodal emotion recognition method for providing more adequate feedback to the learners through an online communication skills training. Herein, timely feedbac...

Recent years have seen the emergence of Web2.0, in which users are not only passive recipients of the featured content, but actively engaged in constructing it. Sites such as ‘Facebook’, ‘Myspace’ are typical examples of this, as are blogs that allow users to present themselves online, to write about their daily lives or even to establish themselves as an authority on a particular subject.
