    Lecture: Harvesting Knowledge for Business Intelligence
    With the growth rate of information volume, information access and knowledge management in enterprises has become challenging. This lecture aims to describe the importance of semantic technologies (ontologies) and knowledge extraction techniques for knowledge management, search and capture in e-business processes. We will present a state of the art of ontology learning approaches from textual data and web environment and their integration in enterprise systems to perform personalized and incremental knowledge harvesting.

    Lecture: Computational Intelligence Methods for Time Series Prediction
    Reliable and accurate prediction of time series is a major issue in several applied domains (e.g. finance, logistics, marketing, energy) and requires intelligent methods to infer models from observed data. The course will first present some basic notions of statistical machine learning for selecting and assessing prediction models from real temporal data. Then an introduction to linear and nonlinear algorithms for prediction will be made. Finally, we will discuss a number of strategies for accurate prediction over long term horizons which is considered the current frontier of forecasting.

    Lecture: Insights in Business Semantics Management with Case studies from the Flanders Research Information Space Program
    Knowledge management methodologies try to capture the descriptions of business entities in terms of their attributes and relations with other business entities. When those descriptions are needed for interoperability tasks between two or more autonomously developed information systems or for reasoning tasks, those descriptions are often captured in a shared formal specification called an ontology. We present Business Semantics Management (BSM) method, a fact-oriented approach to knowledge modeling grounded in natural language. We first show how fact-oriented approaches differ from approaches in terms of, amongst others, expressiveness, complexity, and decidability and how this formalism is easier for users to render their knowledge. We then explain the different processes in BSM and how the tool suite supports those processes. Finally, we show how the ontologies can be transformed into other formalisms suitable for particular interoperability tasks. All the processes and examples will be taken from industry cases throughout the lecture.

    Lecture: Visualizing and Exploring Complex Multidimensional Data
    At several crucial steps of the BI process, humans have to make decisions: they need to understand complex information and data extracted from large databases and produced by complex analytical processes. Information Visualization aims at showing that wealth of data in a meaningful way. Visual Analytics goes a step further by tightly coupling the analytical loop with the visualization loop to allow exploratory analysis and visualization. Building effective visualization and interaction techniques is hard because it relies on well understood psychological mechanisms that are not generative: empirical studies are needed to verify the effectiveness of the techniques and we will describe what works and what does not (despite being trendy and cool sometimes). Combining visualization and analysis is an even bigger challenge that requires new analytical algorithms and special software infrastructures to support interactive-time explorations that scale. We will describe some of the techniques and challenges in this new area.

    Lecture: Managing Complex Multidimensional Data
    Multidimensional database concepts such as cubes, dimensions with hierarchies, and measures are a cornerstone of business intelligence. However, the standard data models and system implementations (OLAP) for multidimensional databases are sometimes not able to capture the complexities of advanced real-world application domains. This lecture will focus on how to manage such complex multidimensional data, including complex dimension hierarchies, complex measures, and integration of multidimensional data with complex external data. We will look at how complex multidimensional data emerge in complex application domains such as medical data, location-based services, energy data, music data, web data, and text data, and present solutions for these domains that support multidimensional business intelligence.

    Lecture: Big Data Analytics on Modern Hardware Architectures
    Big data analytics has the goal to analyze massive datasets, often in the Terabyte or even Petabyte scale, which increasingly occur in web-scale business intelligence problems. Today, many different hardware architectures apart from traditional CPUs can be used to process data. GPUs or FPGAs, among other new hardware, are usually employed as co-processors to accelerate query execution. The common point of these architectures is their massive inherent parallelism as well as a different programming model (single instruction, multiple data) compared to classical von-Neumann CPUs. This lecture introduces big data analytics and typical applications. It then describes several architectures for hardware supported parallel processing, discusses research and commercial systems for big data analytics and describes the underlying query processing algorithms.

    Lecture: Large Graph Data Mining and Data Warehousing
    With the recent growth of the graph-based data, the large graph processing becomes more and more important. In order to explore and to extract knowledge from such data, graph mining methods, like community detection, is a necessity. Although the graph mining is a relatively recent development in the Data Mining domain, it has been studied very intensively under different guises (biology, social networks, telecommunications and Internet). The legacy graph processing tools mainly rely on single machine computational capacity, which cannot process large graph with billions of nodes. Therefore, the main challenge of new tools and frameworks lies on the development of new paradigms that are scalable, efficient and flexible. In this course, we will review the new paradigms of large graph processing and their applications to graph mining domain. The course will be organised as a walk through different industrial needs in terms of graph mining passing by the existing solutions. Finally, we will expose a set of open research questions fitted with some new business requirements such us the graph data warehouse and the modelling evolution required to design this new generation of data mart.

    Lecture: Knowledge Discovery from Constrained Relational Data
    Many established KDD methods assume samples of homogeneous entities and build models of attribute-value associations or dependencies as result of the data mining process. In recent years, mining of data from heterogeneous and interlinked entity classes has attracted considerable interest. These data are often represented as graphs with rich node and link attributes. In practice, these node and link attributes are constrained by logical conditions, which usually are given as business rules. Statistical relational learning (SRL) is a common name for several approaches appropriate to this kind of constrained relational data mining. SRL applications build on extensions mostly of Bayesian networks and Markov random fields. The first part of this tutorial will motivate SRL by innovative BI applications in risk management. Building on results of EU research, we show the effective contributions of SRL in operational risk assessment. The second part of the tutorial will introduce the generic framework of Markov and Bayesian logic networks. Inferencing, propagation of evidence and parameter learning will be described and demonstrated for use cases building on different specific SRL approaches. We will also discuss available tools and products. A final section on other successful applications and emerging application fields for SRL will conclude the tutorial.

    Lecture: An Introduction to Business Process Modeling
    Nowadays, with increased globalization, organizations are facing stronger competition and to maintain competitiveness, they must describe, standardize, and adapt the way they react to certain types of business events, and how they interact with partners, competitors, and customers. Business Process Modeling (BPM) is the activity of representing the processes of an organization, so that they may be analyzed and improved. Starting from the underlying notion of Workflow modeling, this chapter introduces the basic concepts for modeling and implementing business processes using current information technologies and standards, such as Business Process Modeling Notation (BPMN) and Business Process Execution Language (BPEL). We also address the novel, yet growing, topic of Business Process Mining, and point out to open research challenges in the area.
