Welcome to COMMONSENSE 2013!


We invite submissions for presentation at Commonsense-2013, to be held in Cyprus, May 27-29, 2013.

Endowing computers with common sense is one of the major long-term goals of Artificial Intelligence research. One approach to this problem is to formalize commonsense reasoning using representations based on formal logic or other formal theories such as algebraic representations. The challenges to creating such a formalization include the accumulation of large amounts of knowledge about our everyday world, the representation of this knowledge in suitable formal languages, the integration of different representations in a coherent way, and the development of reasoning methods that use these representations.

A decade ago, commonsense reasoning was considered visionary and long term, but it is now considered highly relevant for current applications, such as robotic systems that can interact with humans in open environments, and information extraction systems that use commonsense knowledge together with corpus-based learning to interpret natural language texts. Commonsense-2013 will have a special track on commonsense reasoning in natural language understanding, including topics such as: speech acts, dialog, text comprehension, synthesizing large corpus NLP techniques with commonsense reasoning, textual entailment, and natural logic. As before, papers that describe applications in which logic-based commonsense reasoning has made a contribution and which can help shape our research agendas in the future are encouraged.

Topics of interest at the symposium include, but are not limited to:

  • Formal representations, reasoning, and algorithms, for specific commonsense domains including:
    • time, change, action, and causality
    • geometric space
    • commonsense physical reasoning
    • commonsense biological reasoning (of plants, animals and humans)
    • mental states and propositional attitudes, such as knowledge, belief, intention, desire, emotion
    • interactions among multiple agents and social relations
    • law and legal reasoning
  • Preformal analysis of original aspects of these domains
  • Applications of commonsense reasoning to specific tasks including:
    • cognitive robotics (action and perception)
    • logic-based planning
    • natural language processing, machine reading, understanding narrative structure, textual entailment, query answering
    • web search and web-based services
    • Semantic Web
    • computer vision
    • computer-aided instruction
    • home automation
    • assistive technologies
    • biomedical informatics; integrating and mapping biomedical ontologies
  • Relations among object-level theories, such as abstraction and contextualization
  • Methods of deductive and plausible reasoning that are applicable to commonsense domains and problems, including:
    • answer set programming
    • heuristic and approximate reasoning
    • nonmonotonic reasoning
    • belief revision
    • probabilistic reasoning
  • Meta-theorems about commonsense theories and techniques such as:
    • metalogical theorems such as completeness theorems
    • computational complexity
  • Methods for creating commonsense knowledge bases, including:
    • statistical and corpus-based machine learning techniques
    • crowd sourcing
    • hand crafting microtheories
    • combinations of the above techniques
  • Relation of other fields, such as philosophy, linguistics, cognitive psychology, game theory, and economics to formal theories of commonsense knowledge.

The symposium aims to bring together researchers who are interested in the formalization and automation of commonsense reasoning. We aim for rigorous and concrete paper submissions. While mathematical logic is expected to be the primary lingua franca of the symposium, we also welcome papers using a rigorous but not logic-based representation of commonsense domains.

Technical papers offering new results in the area are especially welcome; object-level theories are of particular interest. We also welcome demos of practical systems that make use of commonsense reasoning. In addition, survey papers, papers studying the relationship between different approaches, and papers on methodological issues such as theory evaluation, are also encouraged.
