PhD Thesis

Title: Data Mining Approach for Spatiotemporal Relationships Extraction: Application to Natural Risks prediction.

Thesis Supervisor: Prof. Sami Faiz (Full Professor, ISAMM, Tunisia)

Summary: Various studies have been directed to capture time-varying characteristics of spatial data using data mining techniques. Nevertheless, the exploration of these data sets with classical and statistical techniques is a challenging task especially with the existence of many interesting hidden relations and patterns. The present thesis proposes a new approach for the prediction of future spatiotemporal relationships based on spatiotemporal association rules. Such rules demonstrate the evolution of spatial objects and the influence of the spatial distribution of adjacent-areas. Our approach is based on two phases. The first one aims to extend association rules mining techniques to spatiotemporal data. We are interested in looking for spatiotemporal association rules that relate properties of reference objects like large towns with properties of other spatial task-relevant objects. Each relevant object is typically a spatial layer. The extracted patterns are relationships relating the spatial objects (reference objects and relevant objects) during different time periods. This first phase is composed of four steps; the core step is to extract the spatiotemporal relationships, it is handled by spatial queries taking into account time period indication. The second and third steps are devoted respectively to frequent spatiotemporal itemsets generation and spatiotemporal association rules extraction. The fourth step is the refinement of the extracted rules. We propose two measures to evaluate the quality of the obtained spatiotemporal association rules. On the basis of the proposed measures namely the spatial closeness relevance and the time subsequence, only interesting spatiotemporal association rules are retained. The second phase aims to generate spatiotemporal predictive rules. We use a predictive neural network based on a nonlinear time series technique to generate these rules. The learning examples correspond to spatiotemporal association rules and the results are spatiotemporal predictive rules assessing the future spatiotemporal relationships. Such relationships are not to be neglected; they can be a major issue influencing natural risks occurrences. We conduct an experimentation using time series of satellite images describing Megrine zone in the southern coast of Tunis (Tunisia). As a final result, we obtain spatiotemporal predictive rules describing the spatiotemporal relationships evolution between anterior and future dates. The evaluation results show good performance of the proposed approach measured in terms of precision, accuracy, sensitivity, sensibility and other interest measures. Keywords: Spatiotemporal data mining, spatiotemporal association rules, spatiotemporal relationships, neural network, time series, natural risks prediction.
