Context Modeling: Context as a Dressing of a Focus
نویسندگان
چکیده
Contextual Graphs are a context-based formalism used in various real-world applications. They allow a uniform representation of elements of reasoning and of contexts for describing different human tasks such as diagnosis and interpretation. The representation of reasoning by Contextual Graphs supposes an efficient representation of the knowledge associated with a reasoning. Extending the previous view of (1) context relative to a focus, and (2) context as composed of external knowledge and contextual knowledge, in this paper we go a step further by proposing a description of the focus in terms of the instantiation of the contextual elements, which are drawn from domain knowledge. We present the results of this study in a real-world application that we are working on currently, namely the self-evaluation of drivers' behaviors in a situation presented within a large spectrum of contexts.

Improved Bayesian Training for Context-Dependent Modeling in Continuous Persian Speech Recognition
Context-dependent modeling is a widely used technique for better phone modeling in continuous speech recognition. While different types of context-dependent models have been used, triphones have been known as the most effective ones. In this paper, a Maximum a Posteriori (MAP) estimation approach has been used to estimate the parameters of the untied triphone model set used in data-driven clust...

متن کاملContext-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 کاملCONTEXT- ORIENTED ARCHITECTURAL CONSIDERATIONS IN CHAHAR BAGH ABBASI STREET IN ESFAHAN
The view at the apparent composition of the streets of a city is the first visual perception of each person from that city. Charbagh Abbasi Street is a valuable centerpiece in identity of Isfahan as a historical city. Over time, due to body wear and erosion and unplanned renovations, some significant changes have been made in the physical form of this axis, and the identity aspects of the Chaha...
متن کاملAllophone-based acoustic modeling for Persian phoneme recognition
Phoneme recognition is one of the fundamental phases of automatic speech recognition. Coarticulation which refers to the integration of sounds, is one of the important obstacles in phoneme recognition. In other words, each phone is influenced and changed by the characteristics of its neighbor phones, and coarticulation is responsible for most of these changes. The idea of modeling the effects o...
متن کاملElements of Critical Context Studies
In this paper, it is argued that Critical Discourse Studies (CDS) should be extended to also include what may be called Critical Context Studies (CCS). After a summary of the new theory of context, defined in terms of special mental models in episodic memory, subjectively representing the ‘definition of the communicative situation’ by the participants, it is argued how a critical analysis of te...
