Poss-OWL 2: Possibilistic Extension of OWL 2 for an Uncertain Geographic Ontology

Bal-Bourai Safia, Mokhtari Aicha
2014 Procedia Computer Science  
Based on our previous work, we propose a solution for handling uncertainty and for dealing with inconsistency in geographical applications.  ...  Nevertheless, classical ontology languages are not able to represent incomplete and uncertain knowledge, which are very important characteristics of several situations in geographic domain.  ...  Inspired by the theories of stochastic, fuzzy, methods of probabilistic and statistic databases, Hong shu and AL. 33 suggest an uncertainty model including uncertain spatio-temporal data types and spatio-temporal  ...

Towards context-aware search and analysis on social media data

Leon R. A. Derczynski, Bin Yang, Christian S. Jensen
2013 Proceedings of the 16th International Conference on Extending Database Technology - EDBT '13  
We view social media data as a constant stream of data points, each containing text with spatial and temporal contexts.  ...  A notable proportion of social media data comes with explicit or implicit spatial annotations, and almost all social media data has temporal metadata.  ...  This spatially-aware event-reporting scenario places significant and novel demands upon a data management system under constant use, especially with regards to spatio-temporal search.  ...
