kandi X-RAY | sparql-query Summary

sparql-query is a C library typically used in Utilities, Data Manipulation applications. sparql-query has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

sparql-query is a command-line tool for accessing SPARQL endpoints over HTTP. You will need at least glib, libcurl, GNU readline, and libxml2, on a Unix-like system. It has been intentionally designed to 'feel' similar to tools for interrogating SQL databases. For example, you can enter a query over several lines, using a semi-colon at the end of a line to indicate the end of your query. It also supports readline so that you can more easily recall and edit previous queries, even across sessions. It can be used non-interactively, for example from a shell script. It doesn't have difficult or hard to find dependencies so it should build fairly easily on typical Unix-like systems. You can find a list of some existing public SPARQL endpoints on the ESW wiki

How to search a list of Wikidata IDs and return the P31 ("instance of") property using SPARQL?

QUESTION

How to search a list of Wikidata IDs and return the P31 ("instance of") property using SPARQL?

Asked 2022-Mar-05 at 12:16

How do I get the instance type(s) (i.e., property=P31 and associated labels) for multiple Wikidata IDs in a single query? Ideally, I want to output a list with the columns: Wikidata ID | P31 ID | P31 Label, with multiple rows used if a Wikidata ID has more than one P31 attached.

I am using the web query service, which works well in part, but I am struggling to understand the syntax. I have so far managed to work out how to process a list of items, and return each one as a row (simple I know!), but I can't work out how to generate a new column that gives the P31 item:

QUESTION

dotNetRdf Method UpdateGraph not successful with Virtuoso server

Asked 2021-May-07 at 08:30

I have a Virtuoso-Server on a linux machine (I "inherited" it, so I did not set it up myself). I also inherited the OntoWiki frontend connected to the server to manipulate the data. As this is a bit clumsy and very manual, I wrote a C# project to access and display the data. I access the data using dotNetRdf. Reading is no problem, but now I also want to update the data, thus using the UpdateGraph method. To test this, I wrote a small test-project, after this example from the dotNetRdf-Website: https://github.com/dotnetrdf/dotnetrdf/wiki/UserGuide-Triple-Store-Integration#updategraph

This is my implementation.

As answered on the dotNetRDF issue —

The output:format isn't the problem here I think. The issue is that the update transaction is not committed by the code as you have it. The way to do this is to call the Dispose() method on _virtuosoManager. So wrapping your update in a using() block is the best way to go:

Based on the question I asked last time: Applying PageRank to a topic hierarchy tree(using SPARQL query extracted from DBpedia)

As I currently got the PageRank value against the Regulated concept map. Toward the concept "Machine_learning", my currently code is below:

I think you can pass a dictionary to the node_color parameter of the draw function. If you construct that dictionary such that the keys are the node-names and the values are the colours you want to associate with those node-names, then you should be able to get the formatting you want.

e.g. if you have been able to run some SPARQL to generate a list of nodes you want to be green, and another list that you want to be blue, and assuming you've got a green_list and blue_list pair of lists of these nodenames, then you could construct your dict something like this:
