Go ahead and take a look on it if you aspire to learn Natural Language Processing. Keep in mind that this video is a bit demanding, and you should have prior knowledge of basics of data science.


22) Title: Simulate your language

Speaker: John Paton

Duration: 00:27:36 hrs

I was living in another state for almost 6 years and didn’t know the native language of the place. I always used to wonder if they hear my words similar to what I think of theirs. John Paten has answered my question here. He tries to demonstrate how our language looks to people who actually don’t speak it. He makes simple Markov Models for simulating any language in python. He shows various visualisations to understand the similarity and differences between various languages. There are very simple yet interesting insights about different languages regarding the most commonly used letters or whether a language uses long words or shorter ones to express the feelings. After this video you shall be able to understand the working of Markov models and would be able to understand and analyse languages using your models.


End Notes

Just watching these videos wouldn’t make you a better analyst. You need to practice too. For best results, you can take notes from the video. This will help you to quickly refer the topic at a later point in time.

While watching these videos, there were several moments when I felt, there are lot many things in Python which I am yet to explore. Once again I would like to thank python community for being so generous, helpful and always being helpful in time of need.
