Abstract: Linked Data has become an essential part of the Semantic Web. A lot of Linked Data is already available in the Linked Open Data cloud, which keeps growing due to an influx of new data from research and open government activities. However, it is still quite difficult to access this wealth of semantically enriched data directly without having in-depth knowledge about SPARQL and related semantic technologies. In this paper, we present the Linked Data Query Wizard, a prototype that provides a Linked Data interface for non-expert users, focusing on keyword search as an entry point and a tabular interface providing simple functionality for filtering and exploration.

Sparklis: An expressive query builder for SPARQL endpoints with guidance in natural language
Sébastien Ferré,Sébastien Ferré +1 more
TL;DR: SPARKLIS is a Semantic Web tool that helps users explore and query SPARQL endpoints by guiding them in the interactive building of questions and answers, from simple ones to complex ones, and combines the fine-grained guidance of faceted search, most of the expressivity of SParQL, and the readability of natural languages.

- 21 Apr 2020
TL;DR: This work evolves a schema for declaratively specifying how to interact with a data API and develops ScrAPIr, a standard query GUI that enables users to fetch data through any API for which a specification exists, and a second GUI that lets users author and share the specification for a given API.

On the Mental Workload Assessment of Uplift Mapping Representations in Linked Data
TL;DR: Two subjective mental workload instruments, namely the NASA Task Load Index and the Workload Profile, were applied in this study and preliminary results show the reliability of these instruments in measuring the perceived mental workload for the task of creating uplift mappings.

TL;DR: Sindice, a lookup index over resources crawled on the Semantic Web, allows applications to automatically retrieve sources with information about a given resource and allows resource retrieval through inverse-functional properties.
Parallax and Companion: Set-based Browsing for the Data Web
David F. Huynh,David R. Karger +1 more
- 01 Jan 2009
TL;DR: This position paper proposes the set-based browsing paradigm that lets the user traverse graph-based data that will be found on the Data Web in an efficient manner, moving from a set of things to a related set of Things rather than from one single thing to one single other thing.
