Uses Fuseki server to evaluate queries on a dataset. – Linked Data for Professional Education https://ld4pe.dublincore.org Learning resources tagged by competency Thu, 19 Nov 2020 14:45:03 +0000 en-US hourly 1 https://wordpress.org/?v=4.9.16 Jena Full Text Search https://ld4pe.dublincore.org/learning_resource/jena-full-text-search/ Sun, 13 Aug 2017 08:18:11 +0000 https://ld4pe.dublincore.org/learning_resource/jena-full-text-search/ This documentation explains how to configure and use the Full Text extension to Apache Jena's ARQ (the module is included in Fuseki). The extension combines SPARQL and full-text search via Lucene or ElasticSearch (built on Lucene). It gives applications the ability to perform indexed full-text searches within SPARQL queries. Although SPARQL allows the use of regular expressions in FILTER, this is a test on a value retrieved earlier in the query and its use is not indexed. In other words, if you're searching for occurrences of a specific term in the rdfs:label of a bunch of products, then the search will need to examine all selected rdfs:label statements and apply the regular expression to each label in turn. If there are many such statements and many such uses of regex, then it may be appropriate to consider using this extension to take advantage of the performance potential of full text indexing.

]]> A Complete Example of How to Link Data, Part 3 https://ld4pe.dublincore.org/learning_resource/a-complete-example-of-how-to-link-data-part-3-2/ Wed, 16 Nov 2016 05:44:22 +0000 https://ld4pe.dublincore.org/learning_resource/a-complete-example-of-how-to-link-data-part-3-2/ This video picks up where the previous two left off, covering the steps of setting up a Fuseki server to store data, interlinking that data with Silk, and then using Pubby to publish the data on the Web. Demonstrates how to connect entities by their URIs (rather than their labels) using sameAs. The tutorial ends by showing how SPARQL can be used to successfully query and filter the data which has just been published.
