USDA_SPARQL_QUERY in app_kbqa returning no results

[jks17]

Hi,

I have successfully uploaded the USDA data, the ontologies and the three .Trig files to a Blazegraph instance and the example queries on this page: https://foodkg.github.io/whattomake.html work.

However, the fetch tag query in app_kbqa/data_builder/src/recipe.py and the USDA_SPARQL_QUERY in app_kbqa/data_builder/src/config/data_config.py both return no results. My url_endpoint is correct as the other queries are working. I am also able to explore both the USDA data and the Recipe data on the Blazegraph tool.

Kind Regards,
Josh

Hi, @dinani65 did you process the ontofox on foodon.txt successfully (in the recipe-handler folder)?

I have the same problem. @jks17 did u fix it? if so, how?

hey @dinani65 - sorry for the late reply. I did not get it to work entirely (queries still don't work in blazegraph). However, the generated usda-pairs.csv in recipe-handler does provide a link between USDA info and ingredients in recipe1m so I used this for my use case

@jks17 were you still able to build the app_kbqa , I got everything u mentioned working.

[jks17]

@riaz I did get most of it working in the end. There still wasn't an easy way for me to compare USDA info with ingredients. Did you follow the code exactly or did you change something?

I am also facing the same issue. usda_subgraphs.json and usda_entities.json are empty files. Any solution?

Hi, I followed every step and succussfully import the 3 TriG files and the query in app_kbqa/data_builder/config/data_config.py returns a empty set. Did anyone fix this?

Hello. I am facing this issue as well - exactly as described by @jks17. Has anyone been able to find a workaround or a solution to this issue? Kindly help.

嗨，我按照每个步骤操作，成功导入了 3 个 TriG 文件，app_kbqa/data_builder/config/data_config.py 中的查询返回一个空集。有人修复过这个问题吗？

Hello, I encountered an issue while running the code, but I need the files usda-links.trig, foodon-links.trig, and foodkg-core.trig for another project. Could I kindly ask you to provide these files for me?
