With the explosive increase in the generation and utilization of spatiotemporal data sets, many research efforts have been focused on the efficient handling of the large volume of spatiotemporal sets. With the remarkable growth of ubiquitous computing technology, mining from the huge volume of spatiotemporal data sets is regarded as a core technology which can provide real world applications wi...

Although intensive works have been devoted to spatiotemporal modeling during the last two decades, there are only a few models dedicated to relationships between two (or more) moving objects. This paper proposes a classification framework of spatiotemporal relationship models based on the ways spatiotemporal histories are analyzed. First, we discuss model conditions of application. Then we prop...

Many data objects in the real world have attributes about location and time. Such spatiotemporal objects can be found in applications such as Geographic Information Systems (CIS), environmental data management and multimedia databases. Traditional relational database technology is not suitable for managing spatiotemporal data, which are multi-dimensional with complex structures and behaviours. ...

When the information created online by users has a spatial reference, it is known as Volunteered Geographic Information (VGI). The increased availability of spatiotemporal data collected from satellite imagery and other remote sensors provides opportunities for enhanced analysis of Spatiotemporal Patterns. This area can be defined as efficiently discovering interesting patterns from large data ...

With the increasing applications based on location, the researches on spatiotemporal data, especially queries of spatiotemporal data have attracted a lot of attention. XML, as a standard language of information exchanging over the Web, should have the ability to query spatiotemporal data. In this paper, we propose an algorithm, TwigSPFast, for matching a spatiotemporal XML query twig pattern. W...

In this paper, we present a spatiotemporal information integrated RDF data management system, called g-Store. In g-Store, some entities have spatiotemporal features, and some statements have valid time intervals and occurring locations. We introduce some spatiotemporal assertions into the SPARQL query language to answer the spatiotemporal range queries and join queries. Some examples are listed...

Modeling moving objects has become a topic of increasing interest in the area of video databases. Two key aspects of such modeling are spatial and temporal relationships. In this paper we introduce an innovative way to represent the trajectory of a single moving object and the relative spatio-temporal relations between multiple moving objects. The representation supports a rich set of spatial t...

A quantitative model of auditory learning is presented to predict how auditory patterns are stored in the songbird auditory forebrain. This research focuses on the caudomedial nidopallium (NCM) in the songbird telencephalon, a candidate site for song perception and the formation of song auditory memories. The objective is to introduce simplified features of bird song that could be used by the a...

Automatically understanding human actions from video sequences is a very challenging problem. This involves the extraction of relevant visual information from a video sequence, representation of that information in a suitable form, and interpretation of visual information for the purpose of recognition and learning. In this paper, we first present a view-invariant representation of action consi...
