Composability in Modeling and Simulation community which can be defined as the capability to select and assemble a simulation model out of predefined simulation models or components is an important challenge due to the cost and time spent on developing a simulation model. Base Object Model, BOM, is a new standard for developing simulation components and making reusability and composability of c...

Since computing earlier days, people have wanted computers that could interface and be programmed using easy to use tools like speech or gesture. However, until now, such a computer system remains in the realm of scientific fiction. Now, with recent advances in human computer interfaces (such as speech understanding, ubiquitous computing, tablet computers), and in the processing of semantic inf...

We describe our work on using Semantic MediaWiki as a central platform for managing IT services and the underlying technical components within an organization. We present our toolkit of MediaWiki extensions which add ITSM-specific functionalities to Semantic MediaWiki and describe their interactions. We also outline the benefits gained by using Semantic Technologies in IT Service Management.

The update propagation methodology of a semantic database model, IFO, is described. An informal review of IFO, a mathematically defined model which subsumes the structural components of most prominent semantic models in the literature, is also presented.

Semantic service discovery is necessary to facilitate the potential of service providers (many sensors, different characteristics) to change the sensor configuration in a generic surveillance application without modifications to the application’s business logic. To combine efficiency and flexibility, semantic annotation of sensors and semantic aware match making components are needed. This shor...

One of the elements in Persian poetry and sonnets (Ghazal) is penname, which in addition to marking poetry in the name of the poet, sometimes has an amphiboly to another means; but in the poetry of poets such as Hafez - which have a special and coherent intellectual system - in the form of a main metaphor or central metaphor, penname is involved in determining their intellectual system. In this...

Complementing semantic data mining systems by wikis and especially semantic wikis yield a flexible knowledge-rich method. This paper describes a system architecture of a collaborative approach for semantic data mining. The goal is to enhance the design, evaluation and refinement of data mining tasks using semantic technology. Collaborative aspects are introduced by utilizing wiki technology. We...

Producing semantic metadata requires efficient methods, e.g., concept finding, for accessing and using ontologies. To add such functionalities to metadata applications such as cataloging systems in museums, we propose a mash-up approach where ready-to-use user interface components for using specific ontologies are made available to be integrated into applications. As a proof-of-concept, we pres...

With the emergence of the Virtual Enterprise (VE) model for business organization, new enterprise systems are constructed by integrating existing one. The integration is achieved through the composition of components selected from either a collection of components provided by the participating enterprise systems or external trusted sources. The process of component selection and composition is ...

We describe the innovative use of describing an existing natural language “pipeline” using the Semantic Web, and focus on how the performance and results of the components may be described. Earlier work has shown how NLP Web Services can be automatically composed via Semantic Web Service composition, and once the results of NLP components can be stored directly, they can also be used to direct ...
