    Lecture: Eco-design of Data Warehouses
    Being in France, following the U.N. climate change conference that is being held in Paris from 30 November through 11 December, 2015 is a great opportunity and a motivation for French citizens, international visitors, companies, politicians, scientists, etc. to integrate the environmental dimension into their lives as well as into research and development. This can be done by either following well-established strategies or by proposing new initiatives. The efficiency of any initiative strongly depends on the efforts made to have a strategy based on guidelines. As researchers in the field of databases, one of the most active research communities, we are compelled to address energy issues. It should be noticed that DBMS are one of the main energy consumers, as the deluge of data has to be stored and efficiently managed. The database community did not stand idle since the past decade: to this aim, it is constantly proposing initiatives covering both software and hardware. Unfortunately, those initiatives are not supported by strategies that can be reused by companies or researchers that develop new types of DBMS; in particular, we are witnessing a boom in the number of new companies, both big and small, that are building their own DBMS on their favourite platforms. In this talk, we first propose to capitalize on the efforts put into building energy-aware query optimisers, which have the lion’s share of the overall energy consumption. Secondly, we undertake an in-depth analysis of different tasks that a query optimizer performs to evaluate a given query, and we identify their energy sensitivity. Thirdly, we implement our proposal on PostgreSQL. Finally, we present and discuss intensive experiments using mathematical cost models and an energy measurement tool using datasets of TPC-H benchmark to assess the effectiveness of our proposal.

    Lecture: Big Data Warehouses and Analytics: About Scalability and Realtime
    Scalability and Realtime in Data Warehouses and Analytics are important topics today, especially given all the hype about BigData. It is not just about throwing more machines and computing power to solve processing problems. We should learn from the past. We should understand the models and mechanisms used to store, process and analyze big amounts of data efficiently. We should think about whether relational or other organizations should be used, as well as the advantages and disadvantages of each. This talk is about the past, the present and the future of scalable and realtime data processing engines and analytics. The talk will include: Introduction and Concepts; Data Warehouse Scalability:Mechanisms and Limitations; Realtime Data Warehousing; Big Data Warehousing NOW; Benchmarking Scalability; Scalability Models and Total Scalability; Scalable Data Analysis.

    Lecture: Two decades of Pattern Mining
    In 1993, Rakesh Agrawal, Tomasz Imielinski and Arun N. Swami published one of the founding papers of Pattern Mining: ``Mining Association Rules Between Sets of Items in Large Databases''. It aimed at enumerating the complete collection of regularities observed in a given dataset like sets of products purchased together in a supermarket. Beyond the introduction of a new problem, it introduced a new methodology in terms of resolution and evaluation. For two decades, Pattern Mining has been one of the most active fields in Knowledge Discovery in Databases. This talk presents an overview of Pattern Mining based on a bibliometric survey of the literature relying on publications from five major international conferences. It is clear that frequent patterns (frequent itemsets in particular) have focused most of this work. More generally, most algorithms achieve a complete enumeration that tends to overwhelm the analyst with too many discovered patterns. To alleviate this problem, recent approaches involve the end-user within the mining process even if it the completeness is lost.


  • Hannes Voigt

    Hannes Voigt

    Dresden Database Systems Group, TU Dresden, Germany

    Hannes Voigt is a post-doctoral researcher in the Dresden Database Systems Group. During affiliation with the group he has worked on various database topics, ranging from database evolution and versioning, data modelling, management of schema-flexible data, self-adapting indexes, index selection, model-driven databases, and efficient mass data transfer on web services. His Ph.D., finished in 2014, focused on the impact of schema-flexible data on database system architecture. From 2010 to 2011, Hannes worked at SAP Labs, Palo Alto on a predecessor project of the SAP HANA graph management functionality. In the project, he developed a query and analytics language for set-oriented processing of graph nodes including traversals. Since returning to Dresden, he has kept involved in the subsequently started HANA Graph Project at SAP, Walldorf. After finishing the Ph.D., his research interest shifted complete to graph data management. His current research focuses on design declarative graph query and analytics languages based on pattern matching as well as traversal and their efficient processing on NUMA in-memory storage systems.

    Lecture: Graph Analytics
    While the main reason for setting up a database was book keeping of individual items in the 1980s and reporting on them in 1990s, the most progressive driver now is the increasing interest on how things are related and connected. Here, the graph data model is the most natural choice, which makes graph data management very relevant now and in the future. Although graph data management is not a particularly new research field, its newly gained momentum and its lack of standardized solutions makes it still an open field. Analytics is one particular driver behind the newly gained momentum. With the particular nature of analytical questions and the skewed and recursive nature of graph data, graph analytics bears its very own challenges. At the user end, there is no commonly accepted abstraction yet, which is powerful enough for most graph analytical problems as well as declarative enough for query optimization. At the processing end, there is no established solution how to effectively leverage the abundant parallelism of modern hardware in analytical graph processing. In recent years, a multitude of solutions have been proposed. However, no master solution has emerged yet. This lecture gives an introduction into graph analytics as a field and provides an overview of the principle technological concepts proposed so far for expressing graph analytical queries and processing them on modern hardware infrastructures.

    Lecture: Computational Approaches to Translation Studies
    Translated texts, in any language, have unique characteristics that set them apart from texts originally written in the same language. Translation Studies is a research field that focuses on investigating these characteristics. Until recently, research Natural Language Processing (NLP), and in particular in machine translation (MT), has been entirely divorced from translation studies. The main goal of this tutorial is to demonstrate that two areas can benefit each other. First, we will survey some theoretical hypotheses of translation studies. Focusing on the unique properties of translationese (the sub-language of translated texts), we will distinguish between properties resulting from interference from the source language (the so-called ``fingerprints'' of the source language on the translation product) and properties that are source-language-independent, and that are presumably universal. The latter include phenomena resulting from three main processes: simplification, standardization and explicitation. All these phenomena will be defined, explained and exemplified. Then, we will describe several works that use standard (supervised and unsupervised) text classification techniques to distinguish between translations and originals, in several languages. We will focus on the features that best separate between the two classes, and how these features corroborate some (but not all) of the hypotheses set forth by translation studies scholars. Next, we will discuss several computational works that show that awareness to translationese can improve machine translation. Finally, we will touch upon some related issues and current research directions. For example, we will discuss recent work that addresses the identification of the source language from which target language texts were translated. We will show that native language identification (in particular, of language learners) is a closely related task to the identification of translationese. Time permitting, we will also discuss work aimed at distinguishing between native and (advanced, fluent) non-native speakers.
