This article reviews attempts to characterize the mental operations mediated by left inferior prefrontal cortex, especially the anterior and inferior portion of the gyrus, with the functional neuroimaging techniques of positron emission tomography and functional magnetic resonance imaging. Activations in this region occur during semantic, relative to nonsemantic, tasks for the generation of wor...

Automatic deduction of semantic labels for audiovisual data requires awareness of context, which in turn requires processing sequences of audiovisual scenes or events. The representation of such sequences is important for semantic analysis tasks. Whereas, conventionally, sequences of specific short-duration event labels, often hand-annotated for learning detectors or classifiers, have been used...

Encoding semantic relationships between items on word lists (semantic processing) enhances true memories, but also increases memory distortions. Episodic memory impairments in schizophrenia (SZ) are strongly driven by failures to process semantic relations, but the exact nature of these relational semantic processing deficits is not well understood. Here, we used a false memory paradigm to inve...

In this paper, we consider the application of topic modelling to the task of inducting grammar rules. In particular, we look at the use of a recently developed method called orthonormal explicit topic analysis, which combines explicit and latent models of semantics. Although, it remains unclear how topic model may be applied to the case of grammar induction, we show that it is not impossible an...

We introduce a semantic approach to the study of logics for access control and dependency analysis, based on Game Semantics. We use a variant of AJM games with explicit justification (but without pointers). Based on this, we give a simple and intuitive model of the information flow constraints underlying access control. This is used to give strikingly simple proofs of non-interference theorems ...

Typically, services are co-created by service provider and customer. This paper describes an approach to account the full costs of a service considering costs at the provider side as well as on the customer side resulting in a more accurate cost model. Depending on the level of integration of provider and customer, explicit modeling of uncertainty is used to reflect the uncertainty about custom...

Is it possible to discover semantic term relations useful for thesauri without any semantic information? Yes, it is. A recent approach for automatic thesaurus construction is based on explicit linguistic knowledge , i.e. a domain independent parser without any semantic component, and implicit linguistic knowledge contained in large amounts of real world texts. Such texts include implicitly the ...

Most online e-learning systems often demand the pre-requisite requirements between course modules and/or some relationship measures between involved concepts to be explicitly inputed by the course instructors so that an optimizer can be ultimately used to find an optimal learning sequence of involved concepts or modules for each individual learner after considering his/her past performance, lea...

Acquiring information systems specifications from natural language description is presented as a problem class that requires a different treatment of semantics when compared with other applied NL systems such as database and operating system interfaces. Within this problem class, the specific task of obtaining explicit conceptual data models from natural language text or dialogue is being inves...
