This is the best introductory explanation about semantics I've seen so far, thanks!
My left ear liked this
HAHA MINE TOO
To Make Right Ear Like it please reverse the headphone
The best videos explaining the relationship between the two I've seen so far. A great overall introduction about the semantic web. Appreciate very much about the video editing which finds the best timing to show the PPT instead of putting it into a separate window box.
Folks you have to watch this if you were as blur as me when it came to RDF, OWL and the 3 Name alphabet police.
A very comprehensive talk by an expert in the field. And even more amazing is that I just spent 6 days on an AML course. Thanks Tara.
Brilliant!!! Thank you
Excellent presentation, thanks.
Fantastic video. Thanks!
This video is excellent to understand basic idea of RDF and OWL!
Thank you so much, earlier I only could find information about RDF, now your video has helped me gain knowledge about RDF.
Outstanding presentation of a difficult subject. Thanks.
thanks for this lecture
Awesome 👌
Excellent Presentation !!!
This is the best RDF and OWL lecture ever
Thanks mam!!! good tutorial...
the examples were of huge help.
Insightful. This is better than reading an excerpt from a book on the subject.
Excellent work thanks!
Exceptional speaker. Fast, clear, and precise.
Best short description I have seen so far
really it is a very good job .. thank alot
Muchas gracias, muy bueno.
great presentation
excellent job
Remarkable presentation. Allows for easy comprehension of the concepts discussed. Thank you🙏🏾
Thanks for your nice video with clear explanation on RDF & OWL!
Loved it!
Very nice presentation and explaination of the topic thank you.
for this knowledge I have been searching for a month...thank you for this presentation
Great job 👏🏼
Very Nice, every word in your video is good. Please share more videos. If possible share on OWL and GATE tool. Thanks.
It is so good! thank you!
Best 👍
wow, very well explained.
Well delivered. What really strikes me is how a prescriptive knowledge cannot deal with reality. @13:00 just imagine the PM suddenly resigns and the project still goes on to completion. Same with rule-based/grammar and natural language: real language is broken.
Great thanks for sharing this information since , i am trying to understand the CIM network model it now makes sense why we have that.
Exceptional presentation!! Good slides and synergy with her talking points. Good teachers are so very, very rare.
how is this an exceptional presentation?
My left ear loved it
Fabulous presentation Tara
Great presentation. FYI, WOL = OWL, as defined (misspelled) by Owl in Winnie-the-Pooh, so it's its own use case. Owl also defines School as Skull :-)
The naming is a tip of the hat to Bill Martin's 'One World Language'. lists.w3.org/Archives/Public/www-webont-wg/2001Dec/0169.html
Ok. So Am I correct that probably the biggest difference (besides cardinality or union operatars) of OWL vs RDF(S) is that it can capture/imply relationship accross multiple nodes, even if it's not explicitely defined, while RDF(S) cannot?
The challenge is that if you make the edge "is author of", and later you want an entity for "Author" (a role), you've painted yourself into a corner that you can't now connect the Author role to the word "author" in the edge. You basically can't do CLASS -> EDGE -> EDGE. That might not be a big deal in all scenarios, depending on your use cases, but it's something worth considering.
Actually you can do "CLASS" - "EDGE" - EDGE. Infact, more interestingly, you can do "EDGE-...-EDGE" with the step in between staying anonymous. What is very interesting is that OWL can help you infer new EDGE's (e.g if we say "child-of" is the inverse of "parent-of"; then if we define one relationship ( ELROND - parent-of -> EOWYN), and we query for the other edge (EOWYN - child-of -> ?) some tuple stores that support Inferencing (e.g. Stardog) will return "ELROND" even though it does not exist in the data.
@@sureshnair6059 How does Class - Edge - Edge work? Can I do that in Protege?
why does this video have sound only for left speaker?
what madman doing sound recording of this has messed this up?
Too little focus on screen, although the presenter is pleasant to see.
Just writing this comment to easily locate the video.
Interested in #GraphAI as well? We host a great Meetup at April 15-16th: bit.ly/CDLGraphAIMeetup
Since lots of modern applications (Power Apps, for example) want databases as their data source, have you all made a follow-up to this video that outlines how to convert the .owl ontology into a database or triple store? That would be REALLY valuable, because it'd let us ontologists leverage our content in a lot of different applications?
