Every time you surf the internet you encounter a Natural Language Processing, or NLP, application. But what exactly is NLP and how does it work?
In this lightboard video, Master Inventor with IBM, Martin Keen, visually explains what NLP is and why we need it, as well as how NLP takes unstructured human speech and converts it to structured data that a computer can understand.

[@user-cy4ld4cx1c]

who fell in love with this man? really i had to here my lecture once more because of his clam and soft nature

[@sephyshen2510]

Good job, sir. I can feel your passion in the video for sharing NLP fundamentals for people who are interested in. Thank you.

[@4think304]

I am not a really smart lady, which makes it challenging to grasp certain concepts, but you made it super easy to understand NLP and relevant applications. So, thank you, Martin Keen.

[@MuhammadUsman-uu2ei]

Way of explanation is next level. I understand the concept in one go.Thanks 👍

[@SPaICTHub]

Thank you for this explicit explanation of what NLP, NLU, and NLG mean.

[@rachidphinixi2517]

have watched many videos abt nlp but to be honest m this is theh best , it just took me back to the classroom. best professor ever. love your way

[@olhakunt4549]

Thank You for this video, Martin! A positive and professional attitude is so much seen even through the screen. It's fantastic to listen to the real masters in their field who enjoy what they do and are ready to share their knowledge with beginners!

[@eufraniodiogo50]

Completely true!

[@befit_kw7762]

What a relief !! Great work. Hopefully we see the technicality of it and of other stuff as well- I mean in codings how it could be done plus the explanation. I know it would be tough, but you are credible/trusted source in Technology.

[@reggenius]

Apt and concise explaination, love everything about the presentation; background, screen board... everything!

[@eldrigeampong8573]

This is a really amazing explanation. I leant lot of from this tutorial Thanks IBM and Thanks Martin.

[@mandyjacotin8321]

I followed you well - you kept it interesting and clear. Thank you.

[@bharathkm100]

The days are not too far to play a toughest note using piano, fly an airplane and manage household chores using NLP. You explained it really well, thank you!

[@snay71]

this comment will age like milk

[@dorisfang8636]

nice explanation!

[@developer_novice4237]

great job on the lemmatization and stemming example. good vs better & bet vs better

[@hrishikeshaddagatla4789]

I was just starting to learn NLP for my startup idea and you made this damn interesting!!

[@arindambasu8343]

Excellent Video

[@user-bq6ju6rc6v]

Such a brilliant explanation!

[@anjalivs4517]

love your way of teaching...

[@Andersl201]

Love the Futurama reference!

[@thomasedwardking7286]

Amazing video 😊 you've inspired me to do my PhD on this. Beer in New Zealand waiting for you, mate 🍻

[@delanoholmquist]

A bit of AI easily understood. Bravo, Martin 👍

[@abysamurai]

Easy to understand!!! 😊

[@gauravpadole1035]

Better explanation than my university professor. Thank you so much.

[@nishattanzim4774]

Thank you so much. Yah this made a lot of sense.

[@HANNAHLUMERIA-it5rw]

Fascinating really

[@user-kt5qd2tn7h]

Great video ! Congrats ! 😊

[@gogyoo]

I'm about to embark on learning Data Science, so this video helped me deciding I had NO interest whatsoever in NLP. Thank you Martin nevertheless for making this useful primer.

[@soobingbak]

Thank you very much.

[@shkoqader3518]

Thank you so much.

[@sumedhaj9017]

Really nice video! Thanks

[@IBMTechnology]

Thanks for the appreciation and for watching, Sumedha!

[@saqibmumtaz9380]

Best explanation.

[@kiikoman08]

Showing the relationship between structured and unstructured data was very helpful for me. Thanks! I'm still a little uncertain as to why this is considered "A.I." It seems like these rules (lemmitization, etc) are hard coded. If so, how does an NLP model learn?

[@jed2473]

exellent video

[@diodesu]

If this person taught me rocket science, I'd be able to understand it I feel like. Wish there were more videos like this

[@abdullahiabbaabdullahi3926]

I really like the way you made simple NLP. Please can you make a video on how to go about building NLP for low resource languages

[@IBMTechnology]

Hi there! Thank you for the suggestions, we'll see what we can do! 🙂

[@jamesbostick7297]

Fantastic.

[@MayankSinghParmar]

Wonder full video. Subject expalined clearly

[@vlnsatyasaivivekgulupalli3908]

Best introduction!!

[@chetanrawatji]

Thank You ❤

[@Daniela190881]

Hi, Martin Keen! What a wonderful insight of the concept of natural language processing! :) Thank you so much. I have been learning about LLms and this key word and semiotic concept is relevant. Could we compare this processing language to a similar data processing through SQL, for instance using SQL syntax and code with functions like CAST to convert data ? Thanks and Congratulations!

[@008pitu]

Hi Mr Martin Thanks for making these concepts easy for a dummies as I am....😉. One strange question is how to manage in AI to refine this: Your verbal non communication maintains more attention to your topics. I suspect your arm movements, joking or smiling are signs to taken into account. Why I choose your explanations more than that of your colleagues ???? In summary. A grateful way to introduce into this intuitive world. Best Josep Is this issue being studied in AI....?

[@lzh00]

The closing sentence is epic😂

[@hongbo-wei]

Thank you

[@websoftwaredeveloperijtiha3093]

Thanks for sharing this knowledge. Can you tell me how to start to be process with programming language?

[@AllenJohn]

No one is going to bring up the topic on how Martin is writing everything backwards so that we are read it properly?

[@mollyrathore18]

Last 3 videos I was trying to figure out what tool he is using and what is the setup and to realise today that he is writing backwards!!!! 🤯🤯🤯🤯🤯 amazing!!!

[@velo1337]

does nlp always use XML as the structured form of text?

[@cipher3966]

Sentiment analysis that can detect sarcasm? Oh yeah, that's are REALLY useful invention

[@vengateshm2122]

Yes it made a great sense. Whats is IBM readymade solution for NLP? I mean to build a custom chatbot are there any PaaS service provided by IBM?

[@IBMTechnology]

Thanks for watching, Vengatesh! Good questions. You can check out the links in this video's description for info on building apps with NLP and other resources. Hope these help! 🙂

[@vengateshm2122]

@@IBMTechnology Thank You

[@vasudevaraovadoothker5092]

NLP on current machine is one aspect, it is good. the required is natural language machine. it is different from numerical machine. That makes AI more logical and reasoning , my work is that.

[@ennioagc]

what is the difference between text mining and NLP?

[@Flankymanga]

Good content but there was a huge echo with the audio.

[@johnnykidblue]

Did dude say, "I'm a master inventor"? Is it his official job title, or is that a flex?

[@IBMTechnology]

Yes, master inventor is an official title here at IBM.

[@drzafarullah76]

Outstanding. How do you write live with marker?

[@IBMTechnology]

We record through glass and then flip the image in post-production. The presenter writes using a "glow" type dry marker that's lit up by a black light sandwiched between the two panes. Search on "how to do a lightboard video" for more details.

[@plasticochido]

@@IBMTechnology Well done! That's an impressive technique, I just couldn't figure it out heheh

[@mostafar8514]

"the vodka is good but the meat is rotten" is far more superior

[@habeel6848]

how does the computer understand the structured sentence.

[@jaligamaramana]

Beautiful explaintion butt .....Is it a mirror that he is writing on or he is able to write from right to left ?!?

[@IBMTechnology]

See ibm.biz/write-backwards

[@niharikamittapelly7027]

can I know on what u r writing

[@maroxesen1]

Is it just me or is he handwriting the texts' mirror reflections?

[@moshfiqurrahman5996]

Man you should focus on your NTW(Natural Text Writing) :D. No difference between G and S :D

[@Drew0Ranger]

How the heck are you writing in reverse? Are you a robot? 🤔

[@amelm5214]

Same question 🤣

[@rh3892]

I don't want to demystify his abilities, but I am quite sure he writes normally and the video's image is then flipped horizontally later on.

[@SkateAwayTheDay]

@@rh3892 lol nooooooo the magic in the world has disappeared immediately

[@suhaibztv814]

Its like writing on a glass and recording from the other side and then flipping video horizontslly which inverts it for users.

[@user-om6cc1ft2p]

I was wondering the same thing lol

[@JJan953]

you can tell this guy is incredibly smart because he had to write mirrored all video

[@katipunero_ph9920]

He write words in a reverse form?!?! WOAHH Edited: Wait I realized it late that's just a mirror/ flipped horizontally vid

[@Scottfraser250]

I'm pretty sure he has to write in 'mirror' image because we are standing on the opposite of the glass to him. If so, how the hell is he doing that??

[@IBMTechnology]

We flip the image in post-production so the speaker doesn't have to write backwards. That's why the lightboard videos appear to have an unusually high percentage of left-handed presenters.

[@jerbear97]

wait wait, is he writing in reverse?

[@zarakhan1518]

Gorgeous 😍

[@IT-lv1jw]

good lord

[@BillusTinnus]

I miss the powerpoint days. The writing on these boards takes up too much watchtime

[@amateur_football9751]

Honestly I found this confusing, they need to replace this guy with an AI bot, he probably can explain it better
