The Challenge of “Quick and Dirty” Information Quality

Data Quality Challenges in Distributed Live-Virtual-Constructive Test Environments

Information Quality Research Challenge

As information technology becomes an integral part of daily life, increasingly, people understand the world around them by turning to digital sources as opposed to directly interacting with objects in the physical world. This has ushered in the age of Ubiquitous Digital Intermediation (UDI). With the explosion of UDI, the scope of Information... (more)

Jan. 2016 -- New book announcement

 

Carlo Batini and Monica Scannapieco have a new book:

Data and Information Quality: Dimensions, Principles and Techniques  

Springer Series: Data-Centric Systems and Applications, soon available from the Springer shop

The Springer flyer is available here


Special issue on Web Data Quality

The goal of this special issue is to present innovative research in the areas of Web Data Quality Assessment and Web Data Cleansing. The editors of this special issue are Christian Bizer, Xin Luna Dong, Ihab Ilyas, and Maria-Esther Vidal. See the call for papers for more details.

 

 

New options for ACM authors to manage rights and permissions for their work

ACM introduces a new publishing license agreement, an updated copyright transfer agreement, and a new author-pays option which allows for perpetual open access through the ACM Digital Library. For more information, visit the ACM Author Rights webpage.

 

ICIQ 2015, the International Conference on Information Quality, will take place on July 24 in Cambrigde, MA at the MIT.

Experience and Challenge papers: JDIQ now accepts two new types of papers. Experience papers describe real-world applications, datasets and other experiences in handling poor quality data. Challenges papers briefly describe a novel problem or challenge for the IQ community. See calls for papers for details.

Special Issue on Provenance and Quality of Data and Information: The term provenance refers broadly to information about the origin, context, derivation, lineage, ownership or history of some artifact. The provenance of data is more specifically a form of structured metadata that records the activities involved in data production. The notion applies to a broad variety of data types, from database records, to scientific datasets, business transaction logs, web pages, social media messages, and more. At the same time, different definitions and measures of quality apply to each of these data types, in different domains.

The JDIQ guest editors are Paolo Missier (Newcastle University, UK, paolo.missier@ncl.ac.uk) and Paolo Papotti (Qatar Computing Research Institut, Qatar, ppapotti@qf.org.qa).

Data Standards Challenges for Interoperable and Quality Data

Despite long history of data standards in practice to enable interoperability, there is a limited scientific understanding for their design, development, implementation, and management. We identify research areas to fill this knowledge gap. We further discuss how these challenges can be addressed by extending data quality research into this new research area.

Unifying Data and Constraint Repairs

Integrity constraints play an important role in data design. However, in an operational database, they may not be enforced for many reasons. Hence, over time, data may become inconsistent with respect to the constraints. To manage this, several approaches have proposed techniques to repair the data, by finding minimal or lowest cost changes to the data that make it consistent with the constraints. Such techniques are appropriate for the old world where data changes, but schemas and their constraints remain fixed. In many modern applications however, constraints may evolve over time as application or business rules change, as data is integrated with new data sources, or as the underlying semantics of the data evolves. In such settings, when an inconsistency occurs, it is no longer clear if there is an error in the data (and the data should be repaired), or if the constraints have evolved (and the constraints should be repaired). In this work, we present a novel unified cost model that allows data and constraint repairs to be compared on an equal footing. We consider repairs over a database that is inconsistent with respect to a set of rules, modeled as functional dependencies (FDs). FDs are the most common type of constraint, and are known to play an important role in maintaining data quality. We evaluate the quality and scalability of our repair algorithms over synthetic data and present a qualitative case study using a well-known real dataset. The results show that our repair algorithms not only scale well for large datasets, but are able to accurately capture and correct inconsistencies, and accurately decide when a data repair versus a constraint repair is best.

The Challenge of Improving Credibility of User-Generated Content in Online Social Networks

In every environment of information exchange, Information Quality (IQ) is considered as one of the most important issues. Studies in Online Social Networks (OSNs) analyze a number of related subjects that span both theoretical and practical aspects, from data quality identification and simple attribute classification to quality assessment models for various social environments. Among several factors that affect information quality in online social networks is the credibility of user-generated content. To address this challenge, some proposed solutions include community-based evaluation and labeling of user-generated content in terms of accuracy, clarity and timeliness, along with well-established real-time data mining techniques.

EXPERIENCE: Succeeding at Data Management  BigCo Attempts to Leverage Data

When faced with an explosion in organizational complexity and a need to respond to changing business conditions, BigCompany struggled to respond (traditionally) to a newly perceived data challenge. Being not data-knowledgeable, it did not realize that the traditional approach was not working for anyone. Two full years into the initiative, BigCompany was far from achieving its initial goals. How much more time, money, and effort would be invested before results were achieved? Worse, still, would they be achieved in time to support a larger, critical, and dependent  technology-driven requirement? While the questions remain unaddressed, the considerations increase our collective knowledge of the importance of understanding organizational DM capabilities. This experience material is provided to be the basis for class discussion rather than to illustrate either effective or ineffective handling of any specific situation.
