中文简介: | 语义技术在工业中的一个重要应用是使用OWL 2本体对信息模型进行形式化,以及使用RDF存储和交换应用数据。此外,可以使用基于本体的数据访问(OBDA)方法使用本体将遗留数据虚拟化为RDF。在所有这些应用中,重要的是为领域专家提供查询公式化工具,以通过本体论的查询来表达他们的信息需求。在这项工作中,我们介绍了这样一种工具OptiqueVQS,它是基于我们在挪威国家石油公司和西门子公司的OBDA应用经验以及跨学科工程环境的最佳HCI实践而设计的。OptiqueVQS实现了许多独特的技术,将其与类似的查询公式系统区分开来。特别是,它利用本体投影技术在查询构建过程中实现基于图的本体导航。其次,虽然OptiqueVQS主要是本体驱动的,但它利用采样数据来增强某些数据属性的数据值选择。最后,OptiqueVQS建立在基础良好的需求、设计原理和质量属性之上。我们与领域专家和普通用户一起评估了OptiqueVQS,并将我们的系统与著名的视觉系统进行了定性比较,以实现本体驱动的查询公式化和语义数据的探索。OptiqueVQS在线提供,可与OBDA场景一起下载。 |
课程简介: | An important application of semantic technologies in industry has been the formalisation of information models using OWL 2 ontologies and the use of RDF for storing and exchanging application data. Moreover, legacy data can be virtualised as RDF using ontologies following the ontology-based data access (OBDA) approach. In all these applications, it is important to provide domain experts with query formulation tools for expressing their information needs in terms of queries over ontologies. In this work, we present such a tool, OptiqueVQS, which is designed based on our experience with OBDA applications in Statoil and Siemens and on best HCI practices for interdisciplinary engineering environments. OptiqueVQS implements a number of unique techniques distinguishing it from analogous query formulation systems. In particular, it exploits ontology projection techniques to enable graph-based navigation over an ontology during query construction. Secondly, while OptiqueVQS is primarily ontology driven, it exploits sampled data to enhance selection of data values for some data attributes. Finally, OptiqueVQS is built on well grounded requirements, design rationale, and quality attributes. We evaluated OptiqueVQS with both domain experts and casual users and qualitatively compared our system against prominent visual systems for ontology-driven query formulation and exploration of semantic data. OptiqueVQS is available online and can be downloaded together with an example OBDA scenario. |
