问题 I am using Apache Jena Fuseki Server for Storing Geo Coordinates of location. How to find out that if two polygons or two rectangles intersect each other inside Fuseki. Please share links related to it if possible. Thank you. 来源： https://stackoverflow.com/questions/61187841/how-to-find-the-polygons-intersection-inside-apache-fuseki-server

问题 New to fuseki/jena here. I managed to get fuseki to run with OWLFBRuleReasoner using tdb1 no problem, but can't make it work with tdb2 (http://jena.apache.org/2016/tdb#). I could not find an explicit example of configuration that uses both TDB2 and OWLFBRuleReasoner, so I just converted this one (that works) @prefix : <http://base/#> . @prefix tdb: <http://jena.hpl.hp.com/2008/tdb#> . @prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . @prefix ja: <http://jena.hpl.hp.com/2005/11

问题 I follow up on query where the schema.org database is used to find the number of children of a class - as a simpler database than my application. I want to get the names of the children concatenated in alphabetic order. The query prefix schema: <http://schema.org/> prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> select ?child (group_concat (?string) as ?strings) where { ?child rdfs:subClassOf schema:Event . ?grandchild rdfs:subClassOf ?child . bind (strafter(str(?grandchild), "http:/

问题 I am trying to create a Fuseki SPARQL server on my machine. The documentation on the Jena website describes how to create such a server from the command-line, here: http://jena.apache.org/documentation/serving_data/. I am looking for a way of creating and initializing such a server just using the Jena Java API. I have looked over the Jena API but have not made any progress in working out how to proceed. Has anyone done this before? 回答1: Yes this is possible but it is not how Fuseki was

问题 I may just be going at this wrong, but I am not sure how to interact with Apache Jena on my computer. I think my main question revolves around where I store files and how I run them. I use Atom editor and work in Python and Javascript normally. My goal here is to get a handle of how Jena and Fuseki work then potentially using Fuseki for the backend of a web app. The tutorial, An Introduction to RDF and the Jena RDF API, links to Java files. Where do I store this file on my desktop and how can

问题 I'm looking to provide some summary stats for a data set and I want to list the different types of edge entities and node(vertex) entities in the graph. For example: -> In Twitter Social network graph of users and following relationship (Homogeneous graph), there is only one type of vertex entity (user), but in heterogeneous graphs such as ConceptNet data, it will have multiple values. -> The edge entities can be computed by just counting the different number of predicates I believe using the

问题 I'm serving a dataset containing 10-20 named graphs from a TDB dataset in Fuseki 2. I'd like to use a reasoner to do inference on my data. The behaviour I'd like to see is that triples inferred within each graph should appear within those graphs (although it would be fine if the triples appear in the default graph too). Is there a simple way of configuring this? I haven't found any configuration examples that match what I am trying to do. The configuration I've tried is very similar to the
