A Finite-State Temporal Ontology and Event-Intervals
نویسنده
چکیده
A finite-state approach to temporal ontology for natural language text is described under which intervals (of the real line) paired with event descriptions are encoded as strings. The approach is applied to an interval temporal logic linked to TimeML, a standard mark-up language for time and events, for which various finite-state mechanisms are proposed.

Context-aware Modeling for Spatio-temporal Data Transmitted from a Wireless Body Sensor Network
Context-aware systems must be interoperable and work across different platforms at any time and in any place. Context data collected from wireless body area networks (WBAN) may be heterogeneous and imperfect, which makes their design and implementation difficult. In this research, we introduce a model which takes the dynamic nature of a context-aware system into consideration. This model is con...

متن کاملAnalysis of Applying Event-triggered Strategy on the Model Predictive Control
In this paper, the event-triggered strategy in the case of finite-horizon model predictive control (MPC) is studied and its advantages over the input to state stability (ISS) Lyapunov based triggering rule is discussed. In the MPC triggering rule, all the state trajectories in the receding horizon are considered to obtain the triggering rule. Clearly, the finite horizon MPC is sub-optimal with ...
متن کاملQuery Answering over Fact Bases for Fuzzy Interval Ontologies
Temporal ontologies contain events that are concepts and roles with references to temporal intervals. Therefore, a temporal ontology induces the interval ontology. We consider fuzzy interval ontologies written in a fuzzy Boolean extension of Allen’s interval logic. Syntactically, the extended logic ELA is the set of all Boolean combinations of propositional variables and sentences of Allen’s in...
متن کاملTemporal Pattern Mining and Reasoning using Reference Event based Temporal Relations (RETR)
Reasoning and mining over temporal patterns has to be more specific and accurate for efficient knowledge discovery. The patterns expressed with the temporal interval relationships of Allen have the problem of aggregating many events under one relation “before” and hence leads to ambiguity. In this work an attempt has been made to overcome this by augmenting the “before” relation with four conte...
