Abstract T3

Multi-agent systems (MAS) provide a key technology for the development of complex systems composed by autonomous agents that are able to interact between them.  The agents share a common environment, and they may have a global goal and/or their own goals to pursue. The main benefit of MAS technology is the ability to cope with dynamics.

Abstract T5

Developments of high throughput data acquisition technologies, together with advances in computing and communications, have resulted in an explosive growth in the number, size, and diversity of potentially useful information sources. Furthermore, with the advent of the Semantic Web, there is increased availability of meta data (ontologies) that make explicit the semantic commitments associated with the data sources. This has created unprecedented opportunities for data-driven knowledge acquisition and decisionmaking in a number of emerging increasingly data-rich application domains, such as bioinformatics, environmental informatics, medical informatics, enterprise informatics, security informatics (among others). However, the massive size, semantic heterogeneity, autonomy, and distributed nature of the data repositories present significant hurdles in acquiring useful knowledge from the available data. Against this background, there is an urgent need for software systems for collaborative knowledge acquisition from autonomous, semantically heterogeneous, distributed information sources.

Outline T5

This tutorial will:

  • Introduce some of the specific challenges in the design of software systems for collaborative knowledge acquisition from autonomous, semantically heterogeneous, distributed information sources.
  • Present a sufficient statistics based general framework for learning from such sources.
  • Describe how this framework can be used to transform standard learning algorithms into algorithms for knowledge acquisition from distributed data and show that the resulting algorithms offer rigorous performance guarantees (relative to their centralized, single agent, or batch counterparts that assume centralized access to the entire data set).
  • Introduce ontology-extended data sources (OEDS) to facilitate collaborative analysis of semantically heterogeneous information sources. OEDS make explicit the structure (schema) and semantics (content) of the data sources, as well as the query answering capabilities of these sources.
  • Introduce a framework for specifying semantic correspondences that reconcile the semantic differences between a user view and the individual information sources in some important special cases (e.g., partial order ontologies) that are commonly encountered in practice.
  • Describe how the sufficient statistics based framework for learning from distributed data can be extended to yield theoretically well-founded algorithms for learning from semantically heterogeneous, autonomous information sources.
  • Point out some statistical problems that arise when learning from data in this setting, e.g., problems caused by the differences in the levels of abstraction used by autonomous information sources to describe the objects of interest.
  • Conclude with some open problems and promising avenues for further research.
