Issues using KBpedia demo page

[vemonet]

Hi, I am trying to figure out how to use KBpedia

I went through the demo page: https://kbpedia.org/demo

It says:

KBpedia exploits large-scale knowledge bases and semantic technologies for effective machine learning and data interoperability. Here are some example ways that KBpedia may power knowledge management-oriented Web services or APIs. Try it for yourself: Analyze Web Page Enter a full URL below to see some example uses of KBpedia:

It is unclear as what kind of URL should be put there, and what KBpedia will produce from this URL. Will it try to match it to your KKO and returns metadata about this concept? Will it try to parse the content of the provided URL for concepts (json-ld, RDFa, etc)?

I tried to put URLs of concepts from DBpedia and Wikidata (e.g. https://www.wikidata.org/wiki/Q90), but the demo seems to fail due to loading mixed content (loading HTTP webpages from HTTPS), even if I am providing a HTTPS URL to the Wikidata page

Analyzing a web page leads to this page:

I tried on Google Chrome and Firefox (on Ubuntu 18.04) and get the same mixed content error. I also tried to access KBpedia through HTTP: http://kbpedia.org/demo which should prevent mixed content errors, but the website is automatically redirecting to HTTPS

Is there anything I can do to make it work on my side? And what kind of URL can be provided to the KBpedia demo endpoint?

The 'Demo' has been removed from the Web site. The problems arose as we are transitioning from Clojure to Python. If and when we restore this functionality in Python, we will add the demo back in. For now, we have substituted the SPARQL endpoint.
