2nd AMW School on Data Management

Scalability and Semantics (AMWS-2014)

June 2nd to 3rd 2014 – Cartagena, Colombia.

The AMW School is an intensive two-day event centred around four tutorials on state-of-the-art Data Management techniques covering:

  • Scalability-related topics, including Modern Database systems, NoSQL, Data Mining, Social Web, Big Data, MapReduce, etc.
  • Logic-related topics, including Datalog(+/-), OWL Ontologies, Database Views and Integrity Constraints, Query Reformulation, etc.

Along with the learning-based outcomes, a major objective of the AMW School is to connect together young researchers from Latin America working in the area of Data Management. Looking to the future, the event aims to forge stronger research collaborations among Latin American universities on this important topic.

School’s Invited Speakers and Topics

Dr. C. Mohan

Dr. C. Mohan

Short Bio: Dr. C. Mohan has been an IBM researcher for 32 years in the information management area, impacting numerous IBM and non-IBM products, the research and academic communities, and standards, especially with his invention of the ARIES family of locking and recovery algorithms, and the Presumed Abort commit protocol. This IBM, ACM and IEEE Fellow has also served as the IBM India Chief Scientist. In addition to receiving the ACM SIGMOD Innovation Award, the VLDB 10 Year Best Paper Award and numerous IBM awards, he has been elected to the US and Indian National Academies of Engineering, and has been named an IBM Master Inventor.

He has served on the advisory board of IEEE Spectrum and on the IBM Software Group Architecture Board’s Council. Mohan is a frequent speaker in North America, Western Europe and India, and has given talks in 40 countries. More information can be found in his home page at http://bit.ly/CMohan.

Title: An In-Depth Look at Modern Database Systems

Abstract: This tutorial is targeted at a broad set of database systems and applications people. It is intended to let the attendees better appreciate what is really behind the covers of many of the modern database systems (e.g., NoSQL and NewSQL systems), going beyond the hype associated with these open source, commercial and research systems. The capabilities and limitations of such systems will be addressed. Modern extensions to decades old relational DBMSs will also be described. Some application case studies will also be presented.

Dr. Barbara Poblete

Dr. Barbara Poblete

Short Bio: Dr. Barbara Poblete is an Assistant Professor at the Department of Computer Science at the University of Chile and also an associated Researcher at Yahoo! Labs, Santiago. Barbara received her PhD from University Pompeu Fabra, Barcelona in 2009. Her interests centre around Web research, with topics covering Information Retrieval, Data Mining, Social Media Analysis, Query Log Analysis, Multimedia and Privacy. Her research often involves working with massive amounts of data, using distributed abstractions such as Hadoop and PIG. Barbara's research has received significant press attention down through the years where, for example, her work on analysing Twitter feeds in the aftermath of the 2011 Chilean Earthquake was covered extensively by the Wall Street Journal.

Title: Making Sense of the Social Web

Abstract: The Social Web presents huge opportunities as a unique source of participatory information about the world around us. For example, in emergency response scenarios, Social Web platforms such as Twitter can provide an unprecedented level of near-real-time, highly-detailed information about events on the ground, posted by first-hand witnesses. However, the high quantity and generally low quality of data on the Social Web presents significant challenges when trying to make sense of such streams of information. Massive amounts of unstructured data must be processed. Information must be analysed based on its meaning and sentiment, its context, its spread in the network, and ultimately its credibility. In this tutorial, we will discuss emerging techniques to make sense of the Social Web: how distributed technologies such as Hadoop and PIG can be brought to bear on the massive amounts of data generated in social networks, how the sentiment and credibility of information can be assessed in such settings, and what role privacy has to play.

Dr. Andreas Pieris

Dr. Andreas Pieris

Short Bio: Dr. Andreas Pieris is a post-doctoral researcher at the Department of Computer Science of the University of Oxford since September 2011. He has a degree in Computer Science from the University of Cyprus (2006), an M. Sc. in Mathematics and Foundations of Computer Science (2007), and a Ph. D. in Computer Science (2011), both from the University of Oxford. During his doctoral studies, he has made research contributions to the development of the Datalog+/- family of ontology languages. His research interests include database theory (querying incomplete/inconsistent data), knowledge representation and reasoning (ontology languages and complexity of ontological reasoning), and computational logic (decidability and complexity of fragments of first-order logic). He has served as a program committee member of international conferences (such as AAAI, RR and SOFSEM). For more information, see https://www.cs.ox.ac.uk/people/andreas.pieris/.

Title: Datalog and its Extensions for Knowledge Representation and Reasoning

Abstract: This tutorial gives an extended introduction to the Datalog+/- family of languages for knowledge representation and reasoning. These languages extend plain Datalog –a powerful rule-based formalism originally intended for expressing complex queries over relational data– with key modelling features such as existential quantification and equality in rule-heads, and at the same time apply syntactic restrictions to achieve decidability of ontological reasoning and, in some relevant cases, also tractability. It is apparent that the “+” symbol refers to the additional features, while the “-” symbol refers to the syntactic restrictions. In this tutorial, we first introduce plain Datalog and discuss its limitations for knowledge representation and reasoning purposes. We then present the main Datalog+/- languages, and discuss their relation with the lightweight languages of the OWL family, that is, the standard languages for expressing Semantic Web ontologies. Finally, time permitting, more advanced material related to Datalog+/- will be presented.

Dr. Michael Benedikt

Dr. Michael Benedikt

Short Bio: Dr. Michael Benedikt is a professor at Oxford University's computer science department, and a fellow of University College Oxford. He came to Oxford after a decade in US industrial research laboratories, including a position as Distinguished Member of Technical Staff at Bell Laboratories. He has worked extensively in mathematical logic, finite model theory, verification, database theory, and database systems, and has served as chair of the ACM's main database theory conference, Principles of Database Systems. The current focus of his research is Web data management, with recent projects including querying of the deep Web, querying and integration of annotated data, and querying of web services.

Title: Logic-based Approaches to Reformulation of Database Queries

Abstract: A basic task in database management is to take a query defined over one vocabulary and translate it to a query over another vocabulary. For example, the problem of evaluating a query using a set of views is a special case of this task. In this tutorial we discuss an approach to query reformulation via basic results in logic. In the process, we will overview some fundamental theorems concerning querying with respect to views and integrity constraints, and outline the connection of the problem to recent results in automated reasoning with constraints. We will also mention some outstanding open problems.

Interactive Session

The school will also feature an interactive session of lightening talks, where all participants are allotted a short presentation time to present their research interests. The goal of this session is for attendees to identify common topics, encouraging discussion about potential collaborations.
