Re: work on analyzing or improving the Wikidata ontology

Greetings, Peter PS

Although not strictly an AI topic, I share your email with @everyone  @W3C
AI KR CG mailing list because

1. Its an opportunity to work with Peter who is an early proponent of
intelligent technologies and knows quite a great deal of stuff

2. Wikidata has been a good examples of  plain SW  implementations that
offers simple but robust (semantic) inference mechanism and is open source
Minimally addressed here
https://opendata.stackexchange.com/questions/15780/does-wikidata-offer-inferencing-reasoning

Peter, Please share with us any demo that shows wikidata
reasoning/inferencing capability? Whats the plan for leveraging wikidata to
do AI?

I take this opportunity to welcome all new members to this WG and encourage
you to introduce yourselves tot he list, share what you are working on,
how you plan to contribute etc

Best greetings

Paola DM, Chair
