Share data .... The single researchers does not filter measurement and vision Traditional vision of Science Unbiased Share Knowledge ... Objective Theory Example 1 RDF converted to graph to link to a web resource Objectivity commonly is intended as something that does not depend on experience Reasoning .... Reproducible Quantitative http://snap.ogs.trieste.it Verification Induction-deduction loop Set experiment
Cannot identify a posteriori factors Complex systems Difficulties in replicating experiments Factors intermingle Experiments Measurement Objectivity can be explained as "not just from someone's point of vieww Correlation does not mean causation Low number of cases Convergence of a community portrait observation Epistemic Objectivity Sets of claims or judgments which truth values are not determined privately Difficult to find analogies
Subjectivity is private and objectivity is public
Information and knowledge in different contexts will mean something different. How can we bridge the gaps between the different paradigms? Abduction: Where the resulting state of affairs and the law is known, while the controlling state of affairs is sought. It is good to explore a context which is Knowledge has to be explicit Knowledge is referenced trough labels FORMALIZATION REPRESENTATION uncertain in order to come up with new ideas, but Bridge conceptualization cannot produce definitive conclusions (Pierce 1932) Tool: RDF, Ontologies tools: Graphs, maps, models
Abduction allow multiple points of view to co- exist Scientists live within paradigms: a theoretical or data DATA philosophical framework, a tradition or school that condition their way of thinking. (Kuhn, 1962) Metadata GRAPH Example 2: Using FOAF to link to web resources
