vGMQL - Introducing a Visual Notation for the Generic Model Query Language GMQL
نویسندگان
چکیده
This paper presents a visual query notation for the generic model query language GMQL. So far, GMQL allows for specifying pattern queries as complex set-theoretical formulas. This fact impedes the practical usability of GMQL, because specifying and understanding a query is unintuitive. The visual query notation we propose is a first step towards resolving this shortcoming. We derive objectives for this notation, implement it in a working prototype, as well as evaluate the notation using expert interviews and a literature survey.

GMQL: A graphical multimedia query language
The rapid increase of multimedia data makes multimedia query more and more important. To better satisfy users’ query requirements, developing a functional multimedia query language is becoming a promising and interesting task. In this paper, we propose a graphical multimedia query language called GMQL, which is developed based on a semi-structured data organization model. In GMQL, we combine th...

MOTIVATION Improvement of sequencing technologies and data processing pipelines is rapidly providing sequencing data, with associated high-level features, of many individual genomes in multiple biological and clinical conditions. They allow for data-driven genomic, transcriptomic and epigenomic characterizations, but require state-of-the-art 'big data' computing strategies, with abstraction lev...

متن کاملVisualization of Business Process Modeling Anti Patterns
The most common way to model business processes is to use a graphical modeling language. The most widespread notation are business process diagrams modeled in the language BPMN. In this paper, we formalize structural patterns that can lead to control flow errors in such graphical models. For expressing such error patterns, we use the visual query language BPMN-Q . By using a query processor, a ...
