[@rompstar]

You are a good teacher, Thumbs Up Bro and Keep it up!

[@nandhiniraj2153]

Hi could you please post a video as how to use machine learning algorithms for sentiment analysis or text mining or natural language processing using R language.

[@shanhuahuang3063]

Hi Jalayer, when i ran match (textbag,poswords), it gave me error as there is none for poswords in r. do you know how to fix that?thanks

[@DataCentricInc]

This is great content on Sentiment analysis in R. I also have a channel that discusses text mining & Sentiment Analysis n R on data from the web, PDF documents and data frames.

[@basusumit]

Excellent video. I am able to replicate everything except that the 'poswords' and 'negwords' objects are not found on my R software 3.4 .... Essentially, the plyr and dplyr libraries have some problem. Would you know how to get around this problem?

[@timroberts3746]

Hi! Many thanks for your very helpful video! I'd like to know how I can obtain a list of the matched terms. Keep up the great work!

[@pengkiina9570]

thanks so much ,I just follow your instruction ,but the most frequent words in my case is "rr" which does not show on the plot ,please help me ,thanks . R says :data could not be fit on page. It will not be plotted??

[@ravindarmadishetty736]

Excellent Videos...easy to understand

[@1976JT]

I followed all of your tutorial for word cloud and sentiment analysis, thanks so much. on sentiment analysis here my thoughts: -how can we create a better metric, let's consider we have a text for example 10.000 words, we have 2500 negative words and say 2000 positive, also do you think we should evaluate single word ocurrences within the text or considere repetition of words (neg and pos)? I'm not a programmer I only use code off videos and tutorials like yours -thanks a lot, JT.

[@simeongill8552]

Question.... Where did you get the list of stopwords from ?

[@andreastrelicz2509]

Hi, your tutorial is amazing understandable. Is it possible this using more word expressions insead of single words? I would need interpretation as well instead of only word frequency. Do you know is it possible in R somehow? Thank you Andrea

[@HaSciTech]

could please tell me that what algorithm have you used here

[@lukasbrenner9396]

can you maybe show, how to create the Histogramm regarding the POS-NEG Score. would be lovely

[@khalidalharthi4510]

Very good explanation

[@gamerxxx-ip7mv]

how can you find the frequency of one certain word???

How can we display positive matched words ?

[@PriyankaPandey123]

I am getting a warning of incomplete final line ? and because of that I am not able to get the proper results as it shows [1] NA that's it ... ? can anybody help me out ?

[@rdjalayer]

Go into the text document with a text editor. Go the the last period of the last sentence and hit enter. Then resave. Although we don't see it in standard view, text has a lot of markup that is recorded behind the scene. Every tab, space, new line, etc is recorded and interpreted. After you have done this, come back to R and proceed the same way in importing your text. I hope this helps.

[@PriyankaPandey123]

Yes thanks a lot :) ... Your tutorial is awesome :)

Love these videos. They are even more enjoyable because I feel like Dave Grohl is talking. You sound so much like him :D

[@Soyachid]

Thank you so much for this video, it was very helpful for me. I tried the sentiment analysis on a text of 2712 characters, but I got 0 for the positive and negative words. Is it possible that I have done something wrong ? Thanks.

[@Soyachid]

I followed video 4 and it worked, thank you so much!

[@keshavrathi9916]

If you are still struggling with it you can go to 9:47 seconds of the video and just pause it there. Then write the codes for loading the positive and negative words and after loading try the "Match" function Hope this helps

[@garredsheppard7222]

@@sudheer596 So I re-watched around the 11 minute mark. There are 2 links in the video description for positive and negative words. The video doesn't show how to do this, just says to do it. Copy the text from the links and put them into 2 .txt files (I named mine poswords and negwords) and then add them to your working directory: poswords

Does it mean the sentimental analysis only works for English text? Is it possible to have packages like this for other languages like French?
