One important but often overlooked aspect of human interpretation of multimedia data is the affective information. Affective labels of video content can be extracted automatically from multimedia data streams. These can then be used for content-based retrieval and browsing. In this paper we propose an approach to retrieve the video clips which are similar to the given query in emotion from the video...
A number of studies have examined anomaly detection systems based on training of system call sequences in the normal execution of applications. However, many of these anomaly detection systems have low detection accuracy when the training is not sufficient. This occurs because the normal behavior data obtained through training on one machine cannot be used for detection on another machine. In this...
Sequential electrocardiograms (ECGs) are very useful for personalized diagnosis. It is therefore very useful to search various electrocardiographs or ECG management systems connected to the Internet for a particular patient's ECGs. This is an interesting but not completely solved problem. In this paper, we present an experimental study of our metadata registry aimed at facilitating the search for...
The technique of outlier detection is useful in many real world applications such as detection of network intrusion. It has been studied intensively on deterministic data. However, it is still a novel research field on uncertain data. To our best knowledge, this paper is the first one to focus on distance-based outlier detection on uncertain data, in which each data is affiliated with a certain confidence...
Over the past years, much research work has been done for better integration of data management and knowledge management. However, in real application, manipulating knowledge along with relational or object data in database system is a difficult thing. In this paper, we introduce a novel, pay-as-you-go mechanism for managing data and domain knowledge. We provide the user with materialized and virtual...
Information integration service has changed from the traditional query-oriented to the future user-oriented service. The current research on information integration service focuses on providing personalized service based on user's preference, interest and habit. In order to solve the problem of personality in information integration, a novel method based on object deputy model is proposed and the...
Security mechanisms within DBMSs are far from effective to detect and prevent anomalous behavior of applications and intrusions from attackers. In fact, intrusions executed by unauthorized users to explore system vulnerabilities, and malicious database transactions executed by authorized users, both cannot be detected and prevented by typical security mechanisms. In this paper we proposed a database...
