AutoQGS: Auto-Prompt for Low-Resource Knowledge-based Question Generation from SPARQL [PDF]

arXiv, 2022
This study investigates the task of knowledge-based question generation (KBQG). Conventional KBQG works generated questions from fact triples in the knowledge graph, which could not express complex operations like aggregation and comparison in SPARQL.

ADDING 3D GIS VISUALIZATION AND NAVIGATION TO THE SPARQL QUERY LOOP [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
3D environments allow advanced spatial navigation and visualization, but have traditionally provided limited support for performing non-spatial data analysis operations like filtering, joining, and integrating data on-the-fly.

Medieval Manuscripts and Their Migrations: Using SPARQL to Investigate the Research Potential of an Aggregated Knowledge Graph

Digital Medievalist, 2022
Although the RDF query language SPARQL has a reputation for being opaque and difficult for traditional humanists to learn, it holds great potential for opening up vast amounts of Linked Open Data to researchers willing to take on its challenges.

Temporal Data Representation and Querying Based on RDF

IEEE Access, 2019
With the explosive growth of temporal data, how to query and manage temporal data has become an important research issue. Resource description framework (RDF), as the standard data and knowledge description language of the semantic web, has been widely ...

PepeSearch: Semantic Data for the Masses. [PDF]

PLoS ONE, 2016
With the emergence of the Web of Data, there is a need of tools for searching and exploring the growing amount of semantic data. Unfortunately, such tools are scarce and typically require knowledge of SPARQL/RDF.

Four Lessons in Versatility or How Query Languages Adapt to the Web [PDF]

, 2009
Exposing not only human-centered information, but machine-processable data on the Web is one of the commonalities of recent Web trends. It has enabled a new kind of applications and businesses where the data is used in ways not foreseen by the data ...

Streaming SPARQL - Extending SPARQL to Process Data Streams [PDF]

, 2008
A lot of work has been done in the area of data stream processing. Most of the previous approaches regard only relational or XML based streams but do not cover semantically richer RDF based stream elements. In our work, we extend SPARQL, the W3C recommendation for an RDF query language, to process RDF data streams.

Automatic Detection of Objects in 3D Point Clouds Based on Exclusively Semantic Guided Processes

ISPRS International Journal of Geo-Information, 2019
In the domain of computer vision, object recognition aims at detecting and classifying objects in data sets. Model-driven approaches are typically constrained through their focus on either a specific type of data, a context (indoor, outdoor) or a set of ...
