Description Logics, Rules and Multi-context Systems [chapter]

Luís Cruz-Filipe, Rita Henriques, Isabel Nunes
2013 Lecture Notes in Computer Science  
As an application, we show how a set of design patterns for multi-context systems can be obtained from previous work on Mdl-programs.  ...  In this paper, we look at two of these formalisms, Mdl-programs and multi-context systems, which address different aspects of this combination, and include different, incomparable programming constructs  ...  Acknowledgments The authors wish to thank Graça Gaspar for the fruitful discussions and her insightful comments on a first version of the manuscript.  ...

COMPUTATIONAL LOGICS AND AGENTS: A ROAD MAP OF CURRENT TECHNOLOGIES AND FUTURE TRENDS

Michael Fisher, Rafael H. Bordini, Benjamin Hirsch, Paolo Torroni
2007 Computational intelligence  
Hence there has been a strong research effort directed at using formal logic as the basis for agent descriptions and agent implementation.  ...  Such a logical basis not only presents the clarity and consistency required but also allows for important techniques such as logical verification to be applied.  ...  As we move from systems where we need to know what the system does, to those where we need to know why it did something, we believe that logical approaches to the control and analysis of complex systems  ...

Towards the Extraction of Variability Information to Assist Variability Modelling of Complex Product Lines

Jessie Carbonnel, Marianne Huchard, Clémentine Nebut
2018 Proceedings of the 12th International Workshop on Variability Modelling of Software-Intensive Systems - VAMOS 2018  
The extractive adoption of a product line from a set of individually developed softwares requires to extract variability information from a collection of software descriptions to model their variability  ...  In this paper, we propose research directions to address the issue of extracting more complex variability information, as a part of extended feature models synthesis from software descriptions.  ...  This complexity may arise from the size of the software systems, or from the types of information that have to be represented to model them.  ...

2021 arXiv   pre-print
We propose a hybrid reasoning system to integrate these three tasks and achieve impressive overall performance on the LSAT tests.  ...  The experimental results demonstrate that our system endows itself a certain complex reasoning ability, especially the fundamental reading comprehension and challenging logical reasoning capacities.  ...  To do this, we inherit the executor from § IV-B3 and § IV-B4. We first execute programs from the context to obtain legitimate assignments.  ...
