Creation l.jpg
Creation

  • Jupiter has moons

    • Galileo, Sidereus Nuncius, 1610

  • Relative sizes of the Earth, Sun and Moon

    • Aristarchus's 3rd century BC

    • this image - 10th century AD

Creation4 l.jpg
Creation

  • Little Dipper microarray processors

  • Biology/pharmacology

  • The first beam in the Large Hadron Collider at CERN1 was successfully steered around the full 27 kilometers of the world’s most powerful particle accelerator

Acquisition collection l.jpg
Acquisition & Collection

  • Data acquired directly from scientists

    • Heterogeneous formats

      • multi-media

      • annotations on a spreadsheet

    • Varying quality

      • experimental settings

      • Student vs verified data


Identification cataloging l.jpg

Collectively identifying resources

Group think

Social bookmarking

Participatory cataloging

Eg UNC photographs

Identification & Cataloging


Storage preservation l.jpg
Storage & Preservation

  • Storage

    • 92% on magnetic media

    • 5 exabytes of print, film, magnetic, and optical storage media produced about in 2002

  • Preservation

    • Heterogeneous

    • Changing hardware

    • Changing software

Barriers to access removed l.jpg
Barriers to access removed

  • Environment

    • New source of information providers (Scientists, Granting agencies)

    • NIH Mandated access

  • Consequences

    • No single point of access

    • Different levels of access required

      • HIPPA compliance

      • Maintaining cultural norms


Use and reuse l.jpg
Use and Reuse

  • Data and Text Mining

    • Use data collected for a different purpose

    • Eg a side-effect of one drug becomes the purpse of another

  • Information Synthesis

    • Combine speculative information

  • Literature Based Discovery

    • Uncover transitive connections from text


Data oriented roles l.jpg
Data Oriented Roles

  • Data Consultant

    • Share best practice regarding how to organize & share data

  • Data Distributor

    • Scientists control the data, distributor makes the data available to others

  • Data Manager

    • Manager organizes and keep the data


New roles l.jpg
New Roles

  • Data Service Provider

    • Data conversion and pre-processing

  • Data and Text Analyst

    • Scientist provides the data, analyst applies visualization, data and text mining tools.

  • Embedded Roles (Data Scientist)

    • Information Work flow


Data oriented roles12 l.jpg
Data Oriented Roles

  • Information organization

  • Conceptual Modeling

  • Create and understand

    • ER diagrams

    • UML diagrams

    • Concept maps

Data oriented roles14 l.jpg
Data Oriented Roles

  • Conceptual  relational models

  • Good database design

    • Normalization

    • Methods to enforce

      • data quality

      • referential integrity

    • Ongoing maintenance


New roles15 l.jpg
New Roles

  • Text Mining: A case study

    • All text is not created equal

    • Things that in the way

      • Page breaks

      • Figures

      • Tables

      • Special characters

  • Implications to preservation

Second phase pre-processing

  • Add Identifiers

    • break paragraphs into sentences

    • Add document, section, paragraph, sentence IDs

  • Replacements

    • symbols , references

  • Output:

    Identifiers|One activity that consumes much of a scientists' time is synthesis “the dialectic combination of thesis and antithesis into a higher stage of truth” _BIB_24.

    Identifiers|This dictionary definition reflects the alternative viewpoints that often occur when multiple empirical studies explore the same phenomena.

Embedded roles24 l.jpg
Embedded Roles

  • Workflow

  • Deep understanding

    • Data formats

    • Access norms

    • Reward structures

  • Custom pre-processing


Closing remarks l.jpg
Closing Remarks

  • Not everyone will have every skill

  • Existing skills that will remain critical

    • Strong ties to faculty

    • Strong negotiating skills

    • Knowledge of standards and resources

  • The roles exist, its not clear where they will live within an institution

The ability to think like someone within a discipline
