• 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

Creation

• 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

• Little Dipper microarray processors

• Biology/pharmacology

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

• Collectively identifying resources• Group think

– Social bookmarking– Participatory cataloging

• Eg UNC photographs

Storage & Preservation

Image Source: http://www.cray.com/products/index.htmlhttp://www2.sims.berkeley.edu/research/projects/how-much-info-2003/

• 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

• 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

• 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

• 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

• 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 Roles

• Information organization

• Conceptual Modeling

• Create and understand – ER diagrams– UML

diagrams– Concept maps

Data Oriented Roles

• Conceptual relational models

• Good database design– Normalization– Methods to enforce

• data quality• referential integrity

– Ongoing maintenance

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.

Text Analytics

SAS Text Miner(Association Rules)

IBM Intelligent Miner for text (Clustering)

• Clustering • Categorization• Association Rules

Visualization

NCI-funded research 1995-2001

Embedded Roles

Embedded Roles

• Workflow• Deep understanding

– Data formats – Access norms– Reward structures

• Custom pre-processing

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 institutionThe ability to think like someone within a discipline
