Abstract
Many real-life data can be represented as tree or graph. Different data mining techniques have been recently proposed to mine such complex structured data. These techniques can be broadly classified into two categories: (i) A large number of algorithms have been designed to find different types of pattern from such data by considering them as snapshot data. These techniques are evolution-unaware. (ii) Recently, there has been increasing research efforts in wide variety of domains such as XML, Web, and life sciences that mine evolutionary features of tree and graph structured data to discover novel knowledge. Typically, such knowledge cannot be discovered by mining snapshot data. This tutorial focuses on this second issue. That is, we highlight recent efforts in discovering novel knowledge from the historical evolution patterns of tree and graph structured data.

The tutorial is structured as follows. We motivate the necessity for mining evolution and give an overview of the evolutionary features of various types of tree and graph-structured data. Next, we identify various research issues involved in evolution mining. Specifically, our discussion can be categorized into the following three main components:

• Study of evolution mining for tree-structured data. We use XML and web usage data as representatives of tree structured data.
• Study of evolution mining for graph-structured data. We use web communities, click-through data, and biological net works as representatives of graph-structured data.
• This tutorial session also reveal various application domains of evolution mining (such as social networks, blogs, web event detection, web personalization, XML query caching, protein function prediction, protein-protein interaction prediction, etc).
