CME: A Temporal Relational Model for Efficient Coalescing

M. Al-Kateb, E. Mansour, M.E. El-Sharkawi
12th International Symposium on Temporal Representation and Reasoning (TIME'05)  
In this paper 1 we present a novel temporal relational model through which coalescing becomes quite simple.  ...  The likelihood that a temporal query employs coalescing is very high. However, coalescing is an expensive and time consuming operation.  ...  Sean Wang for their advice on this research.

CHRONOS: A Reasoning Engine for Qualitative Temporal Information in OWL

Eleftherios Anagnostopoulos, Sotiris Batsakis, Euripides G.M. Petrakis
2013 Procedia Computer Science  
We propose CHRONOS, a system for reasoning over temporal information in OWL ontologies.  ...  Representing both qualitative temporal (i.e., information whose temporal extents are unknown such as "before", "after" for temporal relations) in addition to quantitative information (i.e., where temporal  ...  Apart from language constructs for the representation of time in ontologies, there is still a need for mechanisms for the representation of the evolution of concepts (e.g., events) in time.  ...

Guest Editorial: Temporal representation and reasoning

Carlo Combi
2017 Annals of Mathematics and Artificial Intelligence  
As a further consideration, Temporal Representation and Reasoning is a major theoretical and practical research area, as theoretical proposals need often suitable (methodologybased) tuning and extensions  ...  Thus, we may say that theories, methodologies and techniques that explicitly focus on temporal features of information for representation and reasoning purposes are particularly important in many research  ...  For this reason, beginning with TIME'01, we have opened the meeting to active researchers in temporal, spatial, and spatio-temporal representation and reasoning from all areas.  ...

PISEP^2: Pseudo Image Sequence Evolution based 3D Pose Prediction [article]

Xiaoli Liu, Jianqin Yin, Huaping Liu, Yilong Yin
2019 arXiv   pre-print
Specifically, a skeletal representation is proposed by transforming the joint coordinate sequence into an image sequence, which can model the different correlations of different joints.  ...  Compared with the recursive sequence to sequence model, we can improve the computational efficiency and avoid error accumulation significantly.  ...  The possible reason is: for all actions, in general, (a) the movement of the x-axis is the smallest for all joints; (b) the movement of the y-axis of upper limb joints is more violent; (c) the movement  ...
