With increased utilization of data within their operational and strategic processes, enterprises need to ensure data quality and accuracy. Data curation is a process that can ensure the quality of data and its fitness for use. Traditional approaches to curation are struggling with increased data volumes, and near real-time demands for curated data. In response, curation teams have turned to community crowd-sourcing and semi-automatedmetadata tools for assistance. This chapter provides an overview of data curation, discusses the business motivations for curating data and investigates the role of community-based data curation, focusing on internal communities and pre-competitive data collaborations. The chapter is supported by case studies from Wikipedia, The New York Times, Thomson Reuters, Protein Data Bank and ChemSpider upon which best practices for both social and technical aspects of community-driven data curation are described.

  • 7. The Business Need<br /><ul><li>Knowledgeworkers need:
  • 8. Access to the right information
  • 9. Confidence in that information</li></ul>Working incomplete inaccurate, or wrong information can have disastrous consequences <br />
  • 10. The Problems with Data<br />Flawed Data<br />Effects 25% of critical data in world’s top companies (Gartner)<br />Data Quality<br />Recent banking crisis (Economist Dec’09)<br />Inaccurate figures made it difficult to manage operations (investments exposure and risk)<br />“asset are defined differently in different programs”<br />“numbers did not always add up”<br />“departments do not trust each other’s figures”<br />“figures … not worth the pixels they were made of”<br />
  • 11. What is Data Curation?<br />DigitalCuration <br />Selection, preservation, maintenance, collection, and archiving of digital assets<br />DataCuration<br />Active management of data over its life-cycle<br />Data Curators<br />Ensure data is trustworthy, discoverable, accessible, reusable, and fit for use<br />Museum cataloguers of the Internet age<br />
  • 12. What is Data Curation?<br />Data Governance<br />Convergence of data quality, data management, business process management, and risk management<br />Data Curation is a complimentary activity<br />Part of overall data governance strategy for organization <br />Data Curator = Data Steward ??<br />Overlapping terms between communities<br />
  • 13. Data Quality and Curation<br />What is Data Quality?<br />Desirable characteristics for information resource <br />Described as a series of quality dimensions<br />Discoverability, Accessibility, Timeliness, Completeness, Interpretation, Accuracy, Consistency, Provenance & Reputation<br />Data curation can be used to improve these quality dimensions<br />
  • 14. Data Quality and Curation<br />Discoverability & Accessibility<br />Curate to streamline search by storing and classifying in appropriate and consistent manner<br />Accuracy<br />Curate to ensure data correctly represents the “real-world” values it models<br />Consistency<br />Curate to ensure datacreated and maintained using standardized definitions, calculations, terms, and identifiers<br />
  • 15. Data Quality and Curation<br />Provenance & Reputation<br />Curate to track source of data and determine reputation<br />Curate to include the objectivity of the source/producer<br />Is the information unbiased, unprejudiced, and impartial?<br />Or does it come from a reputable but partisan source?<br />Other dimensions discussed in chapter<br />
  • 16. How to Curate Data<br />Data Curation is a large field with sophisticated techniques and processes<br />Sectionprovides high-leveloverview on:<br />Should you curate data?<br />Types of Curation<br />Setting up a curation process<br />Additional detail and references available in book chapter<br />
  • 17. Should You Curate Data?<br />Curation can have multiple motivations<br />Improving accessibility, quality, consistency,…<br />Will the data benefit from curation?<br />Identify business case<br />Determine if potential return support investment<br />Not all enterprise data should be curated<br />Suits knowledge-centric data rather than transactional operations data<br />
  • 18. Types of Data Curation<br />Multiple approaches to curate data, no single correct way<br />Who?<br />Individual Curators<br />Curation Departments<br />Community-based Curation<br />How?<br />Manual Curation<br />(Semi-)Automated<br />Sheer Curation<br />
  • 19. Types of Data Curation – Who?<br />Individual Data Curators<br />Suitable for infrequently changing small quantity of data<br /> (<1,000 records)<br />Minimal curation effort (minutes per record)<br />
  • 20. Types of Data Curation – Who?<br />Curation Departments<br />Curation experts working with subject matter experts to curate data within formal process<br />Can deal with large curation effort (000’s of records)<br />Limitations<br />Scalability: Can struggle with large quantities of dynamic data (>million records) <br />Availability: Post-hoc nature creates delay incurated data availability<br />
  • 21. Types of Data Curation - Who?<br />Community-Based Data Curation<br />Decentralized approach to data curation<br />Crowd-sourcing the curation process<br />Leverages community of users to curate data <br />Wisdom of the community (crowd)<br />Can scale to millions of records<br />
  • 22. Types of Data Curation – How?<br />Manual Curation<br />Curators directly manipulate data<br />Can tie users up with low-value add activities<br />(Sem-)Automated Curation<br />Algorithms can (semi-)automate curation activities such as data cleansing, record duplication and classification<br />Can be supervised or approved by human curators<br />
  • 23. Types of Data Curation – How?<br />Sheer curation, or Curation at Source<br />Curation activities integrated in normal workflow of those creating and managing data<br />Can be as simple as vetting or “rating” the results of a curation algorithm<br />Results can be available immediately<br />Blended Approaches: Best of Both <br />Sheer curation +post hoc curation department<br />Allows immediate access to curated data <br />Ensures quality control with expert curation<br />
  • 24. Setting up a Curation Process<br />5 Steps to setup a curation process:<br />1 - Identify what data you need to curate<br />2 - Identify who will curate the data<br />3 - Define the curation workflow<br />4 - Identity appropriate data-in & data-out formats<br />5 - Identify the artifacts, tools, and processes needed to support the curation process<br />
  • 25. Setting up a Curation Process<br />Step 1: Identify what data you need to curate<br />Newly created data and/or legacy data? <br />How is new data created? <br />Do users create the data, or is it imported from an external source? <br />How frequently is new data created/updated? <br />What quantity of data is created?<br />How much legacy data exists?<br />Is it stored within a single source, or scattered across multiple sources?<br />
  • 26. Setting up a Curation Process <br />Step 2: Identify who will curate the data<br />Individuals, depts, groups, institutions,community<br />Step 3: Define the curation workflow<br />What curation activities are required?<br />How will curation activities be carried out?<br />Step 4: Identity suitable data-in & -out formats<br />What is the best format for the data?<br />Right format for receiving and publishing data is critical<br />Support multiple formats to maximum participation<br />
  • 27. Setting up a Curation Process<br />Step 5: Identify the artifacts, tools, and processes needed to support curation<br />Workflow support/Community collaboration platforms<br />Algorithms can (semi-)automate curation activities<br />Major factors that influence approach:<br />Quantity of data to be curated (new and legacy data)<br />Amount of effort required to curate the data<br />Frequency of data change / data dynamics<br />Availability of experts<br />
  • 28. Overview<br />Curation Background<br />The Business Need for Curated Data<br />What is Data Curation?<br />Data Quality and Curation<br />How to Curate Data<br />Curation Communities and Enterprise Data<br />Case Studies<br />Wikipedia, The New York Times, Thomson Reuters, ChemSpider, Protein Data Bank<br />Best Practices from Case Study Learning <br />
  • 29. Community–based Curation<br />Two community approaches:<br />Internal corporate communities<br />External pre-competitive communities<br />To determine the right model consider:<br />What the purpose of the community is? <br />Will resulting curateddataset be publicly available? Or restricted?<br />
  • 30. Community–based Curation<br />Internal Communities<br />Taps potential of workforce to assist data curation<br />Curate competitive enterprise data that will remain internal to the company<br />May not always be the case e.g. product technical support and marketing data <br />Can work in conjunction with curation dept.<br />Community governance typically follows the organization’s internal governance model<br />
  • 31. Pre-competitive Communities<br />Pre-competitive collaboration<br />Well-established technique for open innovation <br />Notable examples<br />
  • 32. What is Pre-Competitive Data?<br />Two Types of Enterprise Data<br />Propriety data for competitive advantage<br />Common data with no competitive advantage<br />What is pre-competitive data?<br />Has little potential for differentiation<br />Can be shared without conferring commercial advantage to competitor<br />Common non-competitive data<br />Needs to be maintaining and curated<br />Companies duplicate effort in-house incurring full-cost<br />
  • 33. Pre-competitive Communities<br />External pre-competitive communities<br />Share costs, risks, and technical challenges<br />Common curation tasks carried out once inpublic domain rather than multiple timesin each company<br />Reduces cost required to provide and maintain data<br />Can increase the quantity, quality, and access<br />Focus turns to value-add competitive activity<br />Move “competitive onus” from novel data to novel algorithms, shifting emphasis from “proprietary data” to a “proprietary understanding of data”<br />e.g. Protein Data Bank and Pistoia Alliance in Pharma<br />
  • 34. External Pre-competitive Communities<br />Two popular community models are<br />Organization consortium<br />Open community<br />Organization consortium<br />Operates like a private democratic club<br />Usually closed community, members invited based on skill-set to contribute<br />Output data - public or limited tomembers<br />Consortiums follow a democratic process<br />Member voting rights may reflect level of investment<br />Larger players may be leaders of the consortium<br />
  • 35. External Pre-competitive Communities<br />Open community<br />Everyone can participate<br />“Founder(s)” defines desired curation activity<br />Seek public support to contribute to curation activates<br />Wikipedia, Linux, and Apache are good examples of large open communities<br />

  • 79. Social Best Practices<br />Incentives<br />Sheer curationneedsline of sight from data curating activity, to tangible exploitation benefits<br />Lack of awareness of value proposition will slow emergence ofcollaborative contributions<br />Recognizing contributing curators through a formal feedback mechanism<br />Reinforces contribution culture<br />Directly increases output quality<br />
  • 80. Social Best Practices<br />Community Governance Models<br />Effective governance structure is vital to ensure success of community <br />Internal communities and consortium perform well when they leverage traditional corporate and democratic governance models <br />Open communities need to engage the community within the governance process<br />Follow less orthodox approaches using meritocratic and autocratic principles<br />
  • 81. Technical Best Practices<br />Data Representation<br />Must be robust and standardized to encourage community usage and tools development<br />Support for legacy data formats and ability to translate data forward to support new technology and standards<br />Human & Automated Curation<br />Balancing will improve data quality<br />Automated curation should always defer to, and never override, human curation edits<br />Automate validating data deposition and entry<br />Target community at focused curation tasks<br />
  • 82. Technical Best Practices<br />Track Provenance<br />All curation activities should be recorded and maintained as part data provenance effort<br />Especially where human curators are involved <br />Users can have different perspectives of provenance <br />A scientist may need to evaluate the fine grained experiment description behind the data<br />For a business analyst the ’brand’ of data provider can be sufficient for determining quality<br />
  • 83. Conclusions<br />Data curation can ensure the quality of data and its fitness for use<br />Pre-competitive data can be shared without conferring a commercial advantage<br />Pre-competitive data communities<br />Common curation tasks carried out once in public domain<br />Reduces cost, increase quantity and quality<br />
