Tractable reasoning via approximation Problems in logic are well-known to be hard to solve in the worst case.  ...  Our main goal is to define a semantically wellfounded logic for approximate reasoning, which is justifiable from the intuitive point of view, and to provide fast algorithms for dealing with it even when  ...  In this paper we address the problem of scalability in temporal reasoning by providing a collection of new algorithms for efficiently managing large sets of qualitative temporal relations.  ...

approaches of connecting people on the use (automatic) of operational knowledge to solve problems and make decisions based on intellectual cooperation.  ...  Few technologies have the big potential to review how we live, move, and work. Artificial intelligence (AI) is nowdays equivalent of electricity and the Internet.  ...  Instead, if the agent has to build or to use sophisticated models of problem domain and to solve problems at different levels of abstraction, then it is necessary to use semantic networks.  ...

In Defense of Large Qualitative Calculi

Jason Li, Jochen Renz
The next challenge in qualitative spatial and temporal reasoning is to develop calculi that deal with different aspects of space and time.  ...  In this paper we develop a procedure for reasoning about some of the largest known calculi, the Rectangle Algebra and the Block Algebra with about 10661 relations.  ...  It is one of the main challenges in the field of qualitative spatial and temporal reasoning to combine different calculi in order to represent more expressive spatial and temporal information.  ...

How well is causal structure inferred from cooccurrence information?

Peter A. White
2006 The European Journal of Cognitive Psychology  
Judgements were based more on information about temporal relations, even though no guidance on the use of temporal relation information for causal inference was provided.  ...  Individual causal relations can always be understood as elements in a chain or network of unfolding causality, from a row of dominoes toppling and interlinked cogs in a machine to weather systems, disease  ...  It may be that it is more difficult to solve causal reasoning problems with this more indirect verbal mode of presentation.  ...

The Design and Experimental Analysis of Algorithms for Temporal Reasoning [article]

P. vanBeek, D. W. Manchak
1996 arXiv   pre-print
Many applications -- from planning and scheduling to problems in molecular biology -- rely heavily on a temporal reasoning component.  ...  Taken together, the techniques we develop allow a temporal reasoning component to solve problems that are of practical size.  ...  Introduction Temporal reasoning is an essential part of many arti cial intelligence tasks. It is desirable, therefore, to develop a temporal reasoning component that is useful across applications.  ...

A Novel Model for Timed Event Extraction and Temporal Reasoning In Legal Text Documents

Kolikipogu Ramakrishna, Vanitha Guda, B Padmaja Rani, Vinaya Ch
2011 International Journal of Computer Science & Engineering Survey  
Documentation of various Business and Human Resource (HR) applications involve Legal documents. Analysis and temporal reasoning of such documents is a demanding area of research.  ...  The resultant information resolves temporal expressions and deals with issues such as granularity, vagueness, and a reasoning mechanism which models the temporal constraint satisfaction network.  ...  Data from other sources helps to solve this problem.  ...
