A framework for handling fuzzy temporal events
نویسندگان
چکیده
We present a prototype for implementing a framework for handling temporal information using the CTCN (Causal Temporal Constraint Networks) model as the representational schema. In this prototype, named FTAE (Fuzzy Temporal Analysis of Events), the information is structured—according to its characteristics and temporal granularity—in terms of different interpretation contexts that are connected to each other via an inference mechanism that handles imprecision in temporal objects using a fuzzy logic paradigm.

Handling Temporal Uncertainty in Gis Domain: a Fuzzy Approach
This paper is an attempt to introduce a new framework to handle both uncertainty and time in spatial domain. The application of the fuzzy temporal constraint network (FTCN) method is proposed for representation and reasoning of uncertain temporal data. A brief introduction of the fuzzy sets theory is followed by description of the FTCN method with its main algorithms. The paper then discusses t...
متن کاملIntegration of fuzzy scheduling into a planning framework
This paper presents an approach for the representation and handling of soft temporal constraints in a planning framework. It is achieved in two steps. The first one is the representation of soft temporal constraints by means of fuzzy subsets of a real timeline. And the second one is the successful integration of the temporal reasoning capabilities of a scheduler able to handle these constraints...
متن کاملVERSA – Video Event Recognition for Surveillance Applications
VERSA provides a general-purpose framework for defining and recognizing events in live or recorded surveillance video streams. The approach for event recognition in VERSA is using a declarative logic language to define the spatial and temporal relationships that characterize a given event or activity. Doing so requires the definition of certain fundamental spatial and temporal relationships and...
متن کاملFuzziness and Uncertainty in Temporal Reasoning
This paper proposes a general discussion of the handling of imprecise and uncertain information in temporal reasoning in the framework of fuzzy sets and possibility theory. The introduction of fuzzy features in temporal reasoning can be related to different issues. First, it can be motivated by the need of a gradual, linguistic-like description of temporal relations even in the face of complete...
متن کاملFuzzy Time in LTL
In the last years, the adoption of active systems has increased in many fields of computer science, such as databases, sensor networks, and software engineering. These systems are able to automatically react to events, by collecting information from outside and internally generating new events. However, the collection of data is often hampered by uncertainty and vagueness that can arise from th...
