Researcher

B. Chandrasekaran

B. Chandrasekaran researched knowledge-based reasoning and the organization of AI problem-solving methods. His generic-tasks work described reusable activities such as classification and hypothesis assessment. AAAI elected him a Fellow in 1991. A 1997 paper with J. R. Josephson connected these methods with ontologies for sharing problem-solving knowledge. In 2005, with Unmesh Kurup and Bonny Banerjee, he described an architecture combining symbolic and diagrammatic reasoning. He conducted this technical work at Ohio State.

Timeline

  1. 1986 research, reviewed in 1997

    Reusable tasks for expert systems

    Chandrasekaran’s coauthored 1997 paper reviews his generic-tasks framework, citing its 1986 formulation. It describes tasks such as classification, hypothesis assessment and assembling explanations. Complex reasoning systems can combine these methods, making the organization of problem solving an explicit part of AI design.

  2. 1991

    AAAI fellowship

    AAAI elected Chandrasekaran a Fellow in 1991, with Ohio State as his affiliation.

  3. 1997

    Ontologies for problem-solving methods

    With J. R. Josephson, Chandrasekaran published The Ontology of Tasks and Methods. Their paper examines how a shared description of methods can support reuse of problem-solving knowledge. It explains concepts such as evidence, hypotheses and explanatory coverage in the context of knowledge-based systems.

  4. 2005

    Reasoning with diagrams and symbols

    Chandrasekaran, Unmesh Kurup and Bonny Banerjee described a diagrammatic reasoning architecture in 2005. Their model combines symbolic relations with a diagram representation and operators that inspect or change the diagram. The paper presents shared design and experimental work on how the two modes can cooperate.
