Four tutorials will be offered during the conference.

Tutorial 1: Detecting Clones, Copying and Reuse on the Web

Time & Date: 13:30-15:00, April 16th
Speakers: Xin Luna Dong and Divesh Srivastava

 The Web has enabled the availability of a vast amount of useful information in recent years. However, the Web technologies that have enabled sources to share their information have also made it easy for sources to copy from each other and often publish without proper attribution. Understanding the copying relationships between sources has many benefits, including helping data providers protect their own rights, improving various aspects of data integration, and facilitating in-depth analysis of information flow.

The importance of copy detection has led to a substantial amount of research in many disciplines of Computer Science, based on the type of information considered. The Information Retrieval community has devoted considerable effort to finding plagiarism, near-duplicate web pages and text reuse. The Multimedia community has considered techniques for copy detection of images and video, especially in the presence of distortion. The Software Engineering community has examined techniques to detect clones of software code. Finally, the Database community has focused on mining and making use of overlapping information between structured sources across multiple databases and more recently on copy detection of structured data across sources.

In this seminar, we explore the similarities and differences between the techniques proposed for copy detection across the different types of information. We do this with illustrative examples that would be of interest to data management researchers and practitioners. We also examine the computational challenges associated with large-scale copy detection, indicating how they could be detected efficiently, and identify a range of open problems for the community.

Tutorial 2: Query Processing over Uncertain and Probabilistic Databases

Time & Date: 15:30-17:00, April 16th
Speakers: Lei Chen and Xiang Lian

 Recently, query processing over uncertain data has become increasingly important in many real applications like location-based services (LBS), sensor network monitoring, object identification, and moving object search. In many of these applications, data are inherently uncertain and imprecise, thus, we can either assign a probability to each data object or model each object as an uncertainty region. Based on these models, we have to re-define and study queries over uncertain data. In this tutorial, we will first introduce data models that are used to model uncertain and probabilistic data. Then, we will discuss various types of queries together with their query processing techniques. After that, we will introduce recent trends on query processing over uncertain non-traditional databases, such as sets and graphs. Finally, we will highlight some future research direction.

Tutorial 3: Data Stream Mining and Its Applications

Time & Date: 10:45-12:15, April 17th
Speakers: Latifur Khan and Wei Fan

Data streams are continuous flows of data. Examples of data streams include network traffic, sensor data, call center records and so on. Their sheer volume and speed pose a great challenge for the data mining community to mine them. Data streams demonstrate several unique properties: infinite length, concept-drift, concept-evolution, feature-evolution and limited labeled data. Concept-drift occurs in data streams when the underlying concept of data changes over time. Concept-evolution occurs when new classes evolve in streams. Feature-evolution occurs when feature set varies with time in data streams. Data streams also suffer from scarcity of labeled data since it is not possible to manually label all the data points in the stream. Each of these properties adds a challenge to data stream mining.

Multi-step methodologies and techniques, and multi-scan algorithms, suitable for knowledge discovery and data mining, cannot be readily applied to data streams. This is due to well-known limitations such as bounded memory, high speed data arrival, online/timely data processing, and need for one-pass techniques (i.e., forgotten raw data) issues etc. In spite of the success and extensive studies of stream mining techniques, there is no single tutorial dedicated to a unified study of the new challenges introduced by evolving stream data like change detection, novelty detection, and feature evolution. This tutorial presents an organized picture on how to handle various data mining techniques in data streams: in particular, how to handle classification and clustering in evolving data streams by addressing these challenges. The importance and significance of research in data stream mining has been manifested in most recent launch of large scale stream processing prototype in many important application areas. In the same time, commercialization of streams (e.g., IBM InfoSphere streams, etc.) brings new challenge and research opportunities to the Data Mining (DM) community. In this tutorial a number of applications of stream mining will be presented such as adaptive malicious code detection, on-line malicious URL detection, evolving insider threat detection and textual stream classification.

Tutorial 4: Storing, Querying, Summarizing, and Comparing Molecular Networks: The State-Of-The-Art

Time & Date: 10:30-12:00, April 18th
Speakers: Sourav S Bhowmick and Boon-Siew Seah

A grand challenge of systems biology is to model the cell. The cell can be viewed as an integrated network of cellular functions. Each cellular function is defined by an interconnected ensemble of molecular networks and represents the backbone of molecular activity within the cell. The critical role played by these networks along with rapid advancement in high-throughput techniques has led to explosion in molecular interaction data. In this tutorial we explore the data management and mining techniques that have been proposed in the literature for storing, querying, summarizing, and comparing molecular networks and pathways. It offers an introduction to these issues and a synopsis of the state-of-the-art.
