Recent catastrophic landslide events caused large human and material damages. This shows again, that there is still not enough protection against such kinds of natural hazards. In an ongoing research project a new approach to improve early warning systems of landslides is pursued: complex simulations of landslides are coupled with geoinformation systems (GIS). This allows on the one hand for a detailed...
Clustering is considered as the most important unsupervised learning problem. It aims to find some structure in a collection of unlabeled data. Dealing with a large quantity of data items can be problematic because of time complexity. On the other hand high dimensional data is a challenge arena in data clustering e.g. time series data. Novel algorithms are needed to be robust, scalable, efficient...
The existing so-called semantic XML document clustering algorithms usually use a synonymous word library to calculate semantic similarities among XML documents. However, when people create their own XML documents, they name the element randomly and often use lots of abbreviations. Many tags are not real words at all. The XML documents created by different people may appear very different from each...
