Knowledge-based Expressive Technologies within Cloud Computing Environments
Presented paper describes the development of comprehensive approach for
knowledge processing within e-Sceince tasks. Considering the task solving
within a simulation-driven approach a set of knowledge-based procedures for
task definition and composite application processing can be identified. This
procedures could be supported by the use of domain-specific knowledge being
formalized and used for automation purpose. Within this work the developed
conceptual and technological knowledge-based toolbox for complex
multidisciplinary task solv-ing support is proposed. Using CLAVIRE cloud
computing environment as a core platform a set of interconnected expressive
technologies were developed.Comment: Proceedings of the 8th International Conference on Intelligent

Applying MDE tools to defining domain specific languages for model management
In the model driven engineering (MDE), modeling languages play a central role. They range from the most generic languages such as UML, to more individual ones, called domain-specific modeling languages (DSML). These languages are used to create and manage models and must accompany them throughout their life cycle and evolution. In this paper we propose a domain-specific language for model management, to facilitate the user's task, developed with techniques and tools used in the MDE paradigm.Fil: Pérez, Gabriela.

Towards a Domain Specific Language for a Scene Graph based Robotic World Model
Robot world model representations are a vital part of robotic applications.
However, there is no support for such representations in model-driven
engineering tool chains. This work proposes a novel Domain Specific Language
(DSL) for robotic world models that are based on the Robot Scene Graph (RSG)
approach. The RSG-DSL can express (a) application specific scene
configurations, (b) semantic scene structures and (c) inputs and outputs for
the computational entities that are loaded into an instance of a world model.Comment: Presented at DSLRob 2013 (arXiv:cs/1312.5952
Program Synthesis using Natural Language
Interacting with computers is a ubiquitous activity for millions of people.
Repetitive or specialized tasks often require creation of small, often one-off,
programs. End-users struggle with learning and using the myriad of
domain-specific languages (DSLs) to effectively accomplish these tasks.
We present a general framework for constructing program synthesizers that
take natural language (NL) inputs and produce expressions in a target DSL. The
framework takes as input a DSL definition and training data consisting of
NL/DSL pairs. From these it constructs a synthesizer by learning optimal
weights and classifiers (using NLP features) that rank the outputs of a
keyword-programming based translation. We applied our framework to three
domains: repetitive text editing, an intelligent tutoring system, and flight
information queries. On 1200+ English descriptions, the respective synthesizers
rank the desired program as the top-1 and top-3 for 80% and 90% descriptions
respectively
