2016 Universal Access in the Information Society  
This article presents and argues for ontology-based visual query formulation for end users; discusses its feasibility in terms of ontology-based data access, which virtualises legacy relational databases  ...  In this respect, visual methods for query formulation undertake the challenge of making querying independent of users' technical skills and the knowledge of the underlying textual query language and the  ...  query formula,on query evalua,on large, complex, heterogeneous large, complex, heterogeneous, rapid data sources Ontology-based End-user Visual Query Formulation: Why, what, who, how  ...

Problem Formulation in Knowledge Discovery via Data Analytics (KDDA) for Environmental Risk Management

Yan Li, Manoj Thomas, Kweku-Muata Osei-Bryson, Jason Levy
2016 International Journal of Environmental Research and Public Health  
It is shown how the ontology-based knowledge system can provide structured guidance to retrieve relevant knowledge during problem formulation.  ...  A number of ERM analytics and data science domains have recently emerged. For example, behavioral analytics investigate how (and why) users of ERM platforms and applications behave in a given manner.  ...  The main tasks in the ontology design are to determine why the ontology is built, who will use and maintain the ontology, what are the users' characteristics, what domain will the ontology cover, and what  ...

2017 Journal of Ambient Intelligence and Smart Environments  
To this end, this article reports an ontology-based visual query system (VQS), namely OptiqueVQS, how it is extended for a stream-temporal query language called STARQL, a user experiment with the domain  ...  Moreover, recent ontology-based data access (OBDA) technologies enable end users to formulate their information needs into queries using a set of terms defined in an ontology.  ...  Although a considerable amount of work exists on ontology-based visual query formulation for SPARQL, it is limited for ontology-based visual stream-temporal querying (cf. [47] ).  ...

Designing a Federated Multimedia Information System on the Semantic Web [chapter]

Richard Vdovjak, Peter Barna, Geert-Jan Houben
2003 Lecture Notes in Computer Science  
The issue of a user-friendly front-end is addressed by introducing our interface for browsing and querying RDFS-based ontologies.  ...  Third, there also must be an entry point for the end-user, where he is able to explore what the system can do for him and where he can formulate his queries.  ...  User query in RQL Despite its relative intuitiveness, RQL is still too low-level for an average end-user who wants to formulate queries over RDFS-based ontologies.  ...

2013 Big Data Computing  
This chapter proposes steps towards the solution to the data access problem that end-users typically face when dealing with Big Data: • They need to pose ad hoc queries to a collection of data sources,  ...  possibly including streaming sources; • They are unable to query those sources on their own, but are dependent on assistance from IT experts; • The turnaround time for information requests is in the range  ...  This ontology is constructed entirely independently of how the data is actually stored. End users can In other words, queries are formulated according to the end-users' view of the problem domain.  ...
