14TH ALBERTO MENDELZON INTERNATIONAL WORKSHOP ON FOUNDATIONS OF DATA MANAGEMENT

September 22-23, 2021

Since 2006, the Alberto Mendelzon International Workshop on Foundations of Data Management (AMW) brings together top researchers from all over the world, creating the opportunity to discuss and spread research results around the areas of Data Management and the Web.

Due to the situation regarding COVID-19, the AMW Organization has decided to prepare a two-days online event during 2021 so that the community can keep in touch. The selected dates are September 22 and 23.

Registration: The event is open and free of charge. In case you are interested in attending, please fill the registration form available here. We will send you the Zoom link the day before the event.

PROGRAM

AMW'2021 will be a two-days online event. Each day will include the following activities: tutorial (1 hour), interview with the tutorial speaker (20 min), break (20 min), open discussion (1 hour), and closing session (20 min). These activities are planned to run from 9am to 12pm (GMT-5, Lima-Perú time).

Other rooms will be created according to the requirements of the attendees. The participants will be able to move among the rooms according to their preferences.

TUTORIALS

Explanations in Data Management and Artificial Intelligence (Sept. 22)

[The video] [The slides]

ExplainableAI is one of the most active areas of research in AI and machine learning in these days. In this tutorial we will review some recent approaches to providing explanations in data management, knowledge representation and machine learning. In particular, causality-based approaches, model-based diagnosis, and score-based explanations will be described and applied to query answering and outcomes of classification models. We will also show how answer-set programming can be used for reasoning about counterfactual causes for model results.

Leopoldo Bertossi has been Full Professor at the School of Computer Science, Carleton University (Ottawa, Canada) from 2001 to 2019. In September 2019 he took up a full-professorship at Universidad Adolfo Ibañez (UAI, Chile), the oldest and most prestigious fully-private university in Chile. He worked as Senior Computer Scientist at RelationalAI Inc. (Berkeley, CA, USA) Until 2020. He is since 2019 a senior member of the "Millenium Research Institute for Foundations of Data" (IMFD, Chile), a 10-year initiative funded by the Government of Chile. He obtained a PhD in Mathematics from the Pontifical Catholic University of Chile (PUC) in 1988, with a PhD thesis on mathematical logic (model theory) under the supervision of Prof. Joerg Flum (University of Freiburg, Germany). Prof. Bertossi's research interests include data science, database theory, data management, semantic web, intelligent information systems, data management for business intelligence, knowledge representation, uncertain reasoning, logic programming, computational logic, and statistical relational learning.

Natural Language Interfaces to Databases (Sept. 23)

[The video]

Users need to learn and master a complex query language like SQL or SPARQL to access data in knowledge and databases. Another and more natural way to query the data is using natural language interfaces to explore the data. The main challenge in natural language based querying of data is to identify user intent. To interpret the user's natural language query, many systems try to identify the entities in the query and the relationships between them. There are many entity-based solutions in the literature, with varying complexity of the queries that they can generate. In the last couple of years, we have also seen the proliferation of machine learning and deep learning based text-to-SQL solutions. In this tutorial, we will review state-of-the-art natural language interface solutions, and discuss open challenges for their widespread adoption.

Fatma Ozcan works as Principal Software Engineer in the Google Cloud Data Analytics team, since September 2020. Before that, she was a Distinguished RSM and a senior manager at IBM Almaden Research Center working in the information management area and hybrid cloud. She has been recently working on natural language interfaces to data, ontologies, big data, and HTAP. Previously, she worked on Big SQL, and DB2 pureXML. She was one of the main architects of Big SQL, as well as the XQuery and SQL/XML compiler in DB2 pureXML. She is a distinguished member of ACM, a trustee on the VLDB endowment, and the treasurer of ACM SIGMOD.
