industrial-scale r&d it projects depend on many sub-technologies which need to be understood and have their risks analysed before the project can begin for their success. when planning such an industrial-scale project, the list of technologies and the associations of these technologies with each other is often complex and form a network. discovery of this network of technologies is time con...

In the context of integrated software engineering environments, graphs and transformations on them have proven to be a useful technology for describing the structure of and operations on documents in formal languages. We discuss ways of applying this graph technology to more general structured documents. Existing editing environments for general structured documents offer only basic structure-o...

Abstract The application of the existing knowledge graph is widely concentrated in civil fields with sufficient sample size and uniform distribution, especially Internet, finance other fields. Due to particularity its background military field, there a general lack size, which greatly limits support ability atlas technology for intelligent applications. Therefore, how solve problem automatic ex...

Abstract To cope with the increased complexity of systems, models are used to capture what is considered essence a system. Such typically represented as graph, which queried gain insight into modelled Often, results these queries need be adjusted according updated requirements and therefore subject maintenance activities. It thus necessary support writing model adequate languages. However, in o...
