An Approach to the Selection of DSL Based on Corpus of Domain-Specific Documents
Today many problems that are dedicated to a particular problem domain can be solved using DSL. Thus to use DSL it must be created or it can be selected from existing ones. Creating a completely new DSL in most cases requires high financial and time costs. Selecting an appropriate existing DSL is an intensive task because such actions like walking through every DSL and deciding if current DSL can handle the problem are done manually. This problem appears because there are no DSL repository and no tools for matching suitable DSL with specific task. This paper observes an approach for implementing an automated detection of requirements for DSL (ontology-based structure) and automated DSL matching for specific task.
This book constitutes a collection of selected contributions from the 12th International Conference on Perspectives in Business Informatics Research, BIR 2013, held in Warsaw, Poland, in September 2013. Overall, 54 submissions were rigorously reviewed by 41 members of the Program Committee representing 21 countries. As a result, 19 full and 5 short papers from 12 countries have been selected for publication in this volume. This book also includes the two keynotes by Witold Abramowicz and Bernhard Thalheim. The papers cover many aspects of business information research and have been organized in topical sections on: business process management; enterprise and knowledge architectures; organizations and information systems development; information systems and services; and applications.
Different specialists are involved in software development at once: databases designers, business analysts, user interface designers, programmers, testers, etc. It leads to creation and usage in systems designing of various models fulfilled from the different points of view, with different levels of details, which use different modeling languages for the description. Thus there is a necessity of models transformation as between different levels of hierarchy, and within the same level between different modeling languages for creation of united model of system and exporting of models to external systems. The MetaLanguage system is intended to visual domain-specific languages creation. The approaches to development of a model transformation component of MetaLanguage system are considered. This component allows to fulfill vertical and horizontal model transformations of “model-text” and “model-model” types. These transformations are based on graph grammars described by production rules. Each rule contains the left- and right-hand sides. The algorithm of the left-hand side search in the source model and the algorithms of execution of a right-hand side of a rule are described. Transformations definitions for models in ERD notation are presented as example.
This paper presents a system for determining semantic similarity between words that was an entry for the Dialog 2015 Russian semantic similarity competition. The system introduced is primary based on word vector models, supplemented with various other methods, both corpus- and dictionary-based. In this paper we compare performance of two methods for building word vectors (word2vec and GloVe), evaluate how performance varies on different corpus sizes and preprocessing techniques, and measure accuracy gains from supplementary methods. We compare system performance on word relatedness and word association tasks, and it turns out that different methods have varying relative importance for these tasks.
The paper describes the development of a portal about development and use of tools based on the (meta) modeling (using DSM, DSL, etc.). The architecture of a portal, information retrieval subsystem and document management are described.
The purpose of the portal is the creation of "selfdeveloping" resource, which provides intelligent search and automatic processing of the results (documents and sources), easy navigation on the found resources. Implementation is based on the ontologies approach.
The main feature of suggested methods is an integrated approach to development. The approach bases on a multi-level ontology repository. The portal allows searching and analyzing information, creating and researching model, publishing research results. Software gives an opportunity of a flexible customizing. The main topic of this paper is an intelligent information search means based on semantic indexation, automatic document classification, tracking of semantic links between documents and automatic summarization.
This book constitutes the refereed proceedings of the 4th Conference on Knowledge Engineering and the Semantic Web, KESW 2013, held in St. Petersburg, Russia, in October 2013. The 18 revised full papers presented together with 7 short system descriptions were carefully reviewed and selected from 52 submissions. The papers address research issues related to knowledge representation, semantic web, and linked data.
The technologies based on applying a metamodeling and domain-specific languages are widely used at information systems developing. There are many different tools for creating graphical domain-specific language editors with a possibility of determining user’s graphical notations. However they possess disadvantages. The MetaLanguage system is designed to eliminate some of these shortcomings. MetaLanguage is a language workbench which provides creation of visual dynamic adaptable domain-specific modeling languages used in the development of information systems. In paper the approach to development of MetaLanguage DSM-platform is considered. Basic metalanguage constructions of this system are described. The mathematical multilevel domain model with usage of pseudo-metagraphs is constructed. Definitions of the graph and metagraph are given. The algorithm of vertical models transformations is described. The architecture and implementation of the development environment of MetaLanguage toolkit is presented.
The approach to the development of a visual domain-specific language for intelligent portals design is considered. The possibilities of the existing domain-specific languages for web-development is considered, the created language metamodel, fulfilled in the MetaLanguage system is described. This language reduces the semantic gap between portals development tools and domain, allows to involve users who are not professional programmers in the process of portals designing.
The aim of this article is to highlight the relationships between contemporary tendencies in the humanities (the new ontologies) and contemporary architectural practices. The author articulates the distinction between the optics of the «old ontologies» and the new ones. The ontologies considered to be new ones are flat, free from classical opposition between the whole and the parts and based on modality of possibility, but not obligation. Objects and practices traditionally referred to as architecture appear to be based on the principles of the «old ontologies». For them human being is an extraordinary object compared to others, the part-to-whole relationships appear to reflect either the superiority of the whole (society) or the superiority of the part (individual), finally, they are aimed at creating an “it has to be this way” picture. The new ontologies seem to be impossible to apply to architecture in its traditional meaning. Nevertheless, a two-fold link between the new ontologies and architecture can be posed. On the one hand, the former offer a new language to describe the variety of traditional architecture and accept that all of directions, styles and buildings are ontologically coordinate. On the other hand, the new ontologies enable some new architectural practices (computer architecture, architecture of virtual space and speculative architecture) which do not substitute for traditional architecture, but accompany it.
