Need Help with flowsTo Query on example1.nq sample

[amitabh1]

Hi, i am able to run the following query on Apache Jena on example1.nq file, however the query clause ?read graph4code:flowsTo+ ?fit1 . , is not returning the flowsTo objects, is there anything missing to connect the data flow on pandas.read_csv

Query : PREFIX sio: http://semanticscience.org/resource/ PREFIX graph4code: http://purl.org/twc/graph4code/ PREFIX schema: http://schema.org/ PREFIX rdfs: http://www.w3.org/2000/01/rdf-schema#

select * where { graph ?g { ?read rdfs:label "pandas.read_csv." . ?fit1 schema:about "fit" .

?read graph4code:flowsTo+ ?fit1 .

    ?clf rdfs:label ?name .
    ?clf sio:SIO_000061 ?p .
    ?clf schema:text ?txt .
}

}

Hi, I am not sure those examples are updated - we changed the graph representation at some point and actually moved away from the nq representation to JSON. I've created an updated example in: output/static_analysis. Please if possible see if the JSON representation helps you get what you need because that is the representation we work off of. You can always convert that to a graph if you need transitive closure?

Thanks for the pointer, do you have a query sample against this dataset. I can try the json files.

Is there a recommended tool where the json can be loaded for graphical representation.

Hi, no because we use jq to gather what we need or just load the JSON up and pick up what we need. For graphical representation - look at this notebook: https://github.com/wala/graph4code/blob/master/semForms/ExampleAnalysis.ipynb. It shows you how to view the analysis artifacts as a graph. It is meant for illustrative purposes but feel free to extend it with fields in the JSON if you want them. And if you do do that, do contribute back! Thanks!
