1. Transparency, applications, and ab- stuff – effect on tools for e-science: it’s all about Informatics June 21, 2010, IATUL 2010 Peter Fox (RPI and WHOI) pfox@cs.rpi.edupfox@cs.rpi.edu Tetherless World Constellation

2. 2 Working premise Scientists – actually ANYONE - should be able to access a global, distributed knowledge base of scientific data that: appears to be integrated appears to be locally available But… data and information is obtained by multiple means (instruments, models, analysis) using various (often opaque) protocols, in differing vocabularies, using (sometimes unstated) assumptions, with inconsistent (or non-existent) meta-data. It may be inconsistent, incomplete, evolving, and distributed AND created in a form that facilitates generation, not use (except by accident) And… there exist(ed) significant levels of semantic heterogeneity, large-scale data, complex data types, legacy systems, inflexible and unsustainable implementation technology…

5. So what about abduction? No, not the criminal meaning… Is a method of logical inference introduced by Peirce which comes prior to induction and deduction for which the colloquial name is to have a "hunch". Abductive reasoning starts when an inquirer considers of a set of seemingly unrelated facts, armed with an intuition that they are somehow connected. The term abduction is commonly presumed to mean the same thing as hypothesis; however, an abduction is actually the process of inference that produces a hypothesis as its end result 5

6. Abductive Information System? What would this look like in application tools? If you consent that induction is fundamentally part of how an information system is developed, then how to allow for abduction before induction may be possible? Design factors? Architecture factors? Library factors? Cognitive factors? 6

8. Marine habitat - change Scallop, number, density Scallop, size, shape, color, place Scallop, shell fragment Rock What is this? Flora or fauna? Dirt/ mud; one person’s noise is another person’s signal Several disciplines; biology, geology, chemistry, oceanography Several applications; science, fishing, habitat change, climate and environmental change, data integration Complex inter-relations, questions Use case: What is the temperature and salinity of the water and are these marine specimens usual or part of an ecosystem change?

13. Provenance Origin or source from which something comes, intention for use, who/what generated for, manner of manufacture, history of subsequent owners, sense of place and time of manufacture, production or discovery, documented in detail sufficient to allow reproducibility Knowledge provenance; enrich with semantics (especially the relations between concepts previously isolated, and retaining context) and semantically-aware tools

Atlantic, bounding box, where the JGOFs survey was done,...) 3.What new data has been added to this repository since last year (and organize it by project) 4.Show me all the places where the surface temperature in the North Atlantic is 25 degrees during June.
