Wikidata SPARQL Query Tutorial

Thu, 29 Dec 2016 06:44:05 +0000

This video presentation demonstrates how to construct SPARQL queries simply and easily using the Wikidata Query Service. It works through an example of searching for notable females educated at the University of Edinburgh, with results filtered by place of birth. The data is then visualized with images, timelines, maps, and in the new Timeline Viewer using Histropedia.

Querying Semantic Web Data with SPARQL (and SPARQL 1.1)

Abi Evans — Tue, 15 Sep 2015 02:33:08 +0000

This lengthy slide presentation covers SPARQL 1.1. It begins with the fundamentals: graph patterns, operators, and algebraic representations. The second half dives deeply into complex topics: semantics, property paths, navigational capabilities. Description Logics are used throughout to illustrate concepts.

Simple SPARQL Tutorial: Querying a SPARQL Service

Abi Evans — Thu, 13 Aug 2015 03:26:19 +0000

Building on the previous tutorial, which showed how to query a remote dataset using the FROM keyword, this tutorial shows how to query a SPARQL endpoint using the SERVICE keyword. The instructor runs into a few obstacles, but pushes through them.

SPARQL vs. SQL – Intro

Abi Evans — Thu, 13 Aug 2015 03:26:17 +0000

This lesson compares the SPARQL and SQL query languages, which are designed to query RDF and relational data, respectively. It is designed for those who know one and want to learn the other or who need to make some decisions about which to use for some purpose. In keeping with the culture of re-use and integration that pervades the Semantic Web, SPARQL can be used to access relational data as well as RDF. This lesson also briefly mentions two recent specifications for mapping between the two types of data models.
