Keynote Talk: Structured Data in Web Search

Abstract - For the first time since the emergence of the Web, structured data is playing a key role in search engines and is therefore being collected via a concerted effort. Much of this data is being extracted from the Web, which contains vast quantities of structured data on a variety of domains, such as hobbies, products and reference data. Moreover, the Web provides a platform that encourages publishing more data sets from governments and other public organizations. The Web also supports new data management opportunities, such as effective crisis response, data journalism and crowd-sourcing data sets.
I will describe some of the efforts we are conducting at Google to collect structured data, filter the high-quality content, and serve it to our users. These efforts include providing Google Fusion Tables, a service for easily ingesting, visualizing and integrating data, mining the Web for high-quality HTML tables, and contributing these data assets to Google's other services.

Keynote Talk: Scholarly Big Data: Information Extraction and Data Mining

Abstract - Collections of scholarly documents are usually not thought of as big data. However, large collections of scholarly documents often have many millions of publications, authors, citations, equations, figures, etc., and large scale related data and structures such as social networks, slides, data sets, etc. We discuss scholarly big data challenges, insights, methodologies and applications. We illustrate scholarly big data issues with examples of specialized search engines and recommendation systems that use information extraction and data mining in various areas such as computer science, chemistry, archaeology, acknowledgements, reference recommendation, collaboration recommendation, and others.

Biography - Dr. C. Lee Giles [Personal page at PSU] is the David Reese Professor at the College of Information Sciences and Technology at the Pennsylvania State University, University Park, PA.

Keynote Talk: Applying Theory to Practice

Abstract - We discuss the art of applying theory to practice. In particular, we discuss in detail our interactions with two research projects at IBM Almaden: the Garlic project, which built a multimedia database system on top of various existing systems, and the Clio project, which developed tools for converting data from one format to another. We discuss the problems we resolved, and the impact this had both on the Garlic or Clio systems and on the broader scientific community. We draw morals from these interactions, including why theoreticians do better theory by working with system builders, and why system builders build better systems by working with theoreticians. We present the remarkably simple Threshold Algorithm [16], which is optimal in an extremely strong sense: optimal not just in the worst case, or in the average case, but in every case! The Threshold Algorithm and its variants have applications to numerous areas, including information retrieval, fuzzy and uncertain databases, group recommendation systems, and the semantic web.

Biography - Ronald Fagin [Personal Page at IBM] is an IBM Fellow at IBM Research - Almaden. The title of Fellow is IBM's highest technical honor: there are about 70 Fellows among 450,000 IBM employees, and there have been 246 Fellows in the 50 year history of the program.

Fagin received his B.A. in mathematics from Dartmouth College, and his Ph.D. in mathematics from the University of California at Berkeley. In his Ph.D. thesis, he essentially initiated the field of finite model theory. In his thesis he proved what is now known widely as Fagin's Theorem, which says that the important complexity class NP coincides with the class of properties expressible in existential secondorder logic. This is a syntactic characterization of NP, which, remarkably, does not involve explicitly any notion of machine, computation, or time. In his thesis, he also proved the zero-one law of first-order logic, which says that every property expressible in first-order logic is either almost surely true (in an asymptotic probabilistic sense) or almost surely false.

Most of his research has focused on database theory. He first became well-known in databases through his introduction of the strongest normal forms for relational databases. Normal forms describe ways to structure the relations to avoid various anomalies (such as the deletion of one piece of information accidentally leading to the loss of other information). Normal forms are critical for good database design. In recent years, his main focus in database theory has been on the problem of data exchange, where data is translated from one format to another.

He has also been a key leader in the area of reasoning about knowledge, a topic of importance in distributed computing systems, artificial intelligence, cryptography, and game theory. These subjects all deal with systems in which multiple agents are reasoning about the world and about each other's knowledge. Fagin is a co-author of the definitive text on reasoning about knowledge.

Fagin was named a Fellow of IEEE for "contributions to finite-model theory and to relational database theory". He was named a Fellow of ACM for "creating the field of finite model theory and for fundamental research in relational database theory and in reasoning about knowledge". He was named a Fellow of AAAS (American Association for the Advancement of Science), for "fundamental contributions to computational complexity theory, database theory, and the theory of multi-agent systems". He was named Docteur Honoris Causa by the University of Paris, and a "Highly Cited Researcher" by ISI (the Institute for Scientific Information). He won Best Paper awards at the 1985 International Joint Conference on Artificial Intelligence, the 2001 ACM Symposium on Principles of Database Systems, and the 2010 International Conference on Database Theory. He won Test-of-Time Awards at the 2011 ACM Symposium on Principles of Database Systems and the 2013 International Conference on Database Theory. He won a 2011 IEEE Technical Achievement Award "for pioneering contributions to the theory of rank and score aggregation", and the 2012 IEEE W. Wallace McDowell Award "for fundamental and lasting contributions to the theory of databases". He was the winner of the 2004 ACM SIGMOD Edgar F. Codd Innovations Award, a lifetime achievement award in databases, for "fundamental contributions to database theory".

Keynote Talk: Usability in Machine Learning at Scale with GraphLab

Abstract - Today, machine learning (ML) methods play a central role in industry and science. The growth of the Web and improvements in sensor data collection technology have been rapidly increasing the magnitude and complexity of the ML tasks we must solve. This growth is driving the need for scalable, parallel ML algorithms that can handle Big Data. In this talk, we will focus on:
1. Examining common algorithmic patterns in distributed ML methods.
2. Qualifying the challenges of implementing these algorithms in real distributed systems.
3. Describing computational frameworks for implementing these algorithms at scale.
4. Addressing a significant core challenge to large-scale ML -- enabling the widespread adoption of machine learning beyond experts.
In the latter part, we will focus mainly on the GraphLab framework, which naturally expresses asynchronous, dynamic graph.

Biography - Dr. Carlos Guestrin [Personal page at University of Washington] is the Amazon Professor of Machine Learning at the Computer Science & Engineering Department of the University of Washington. He is also a co-founder and CEO of GraphLab Inc., focusing large-scale machine learning and graph analytics. His previous positions include the Finmeccanica Associate Professor at Carnegie Mellon University and senior researcher at the Intel Research Lab in Berkeley. Carlos received his PhD and Master from Stanford University, and a Mechatronics Engineer degree from the University of Sao Paulo, Brazil.

Carlos' current research interests focus on two core aspects of "Big Data": 1) The computing perspective, where he works on developing algorithms,abstractions and systems for tackling large-scale machine learning and graph analytics, and 2) the human perspective, where he focuses on taming information overload, by developing algorithms and representations to help humans understand huge and complex sources of information.

Carlos' work has been recognized by awards at a number of conferences and two journals: KDD 2007 and 2010, IPSN 2005 and 2006, VLDB 2004, NIPS 2003 and 2007, UAI 2005, ICML 2005, AISTATS 2010, JAIR in 2007 & 2012, and JWRPM in 2009. He is also a recipient of the ONR Young Investigator Award, NSF Career Award, Alfred P. Sloan Fellowship, IBM Faculty Fellowship, the Siebel Scholarship and the Stanford Centennial Teaching Assistant Award. Carlos was named one of the 2008 'Brilliant 10' by Popular Science Magazine, received the IJCAI Computers and Thought Award and the Presidential Early Career Award for Scientists and Engineers (PECASE).
