Thank you very much. I have a problem. When I run the Corpus function to create the pdfdatabase, I get the following error: PDF error: Unknown Metadata type: 'XMP'. Could you please help me with that?
Great explanation by explaining concepts in an easy way. You do it with simple ease. Thank you. I was running the same codes and I came across a problem. I was wondering if you could put some light on it. Basically, when I run the Corpus function is gives this error: Error in file(con, "r") : invalid 'description' argument Can you please help?
This is fantastic. Thank you. Could you kindly consider making a video on how to remove the fist say 5 lines from several pdf files and merging them. Or rather combining data from different pdf files after the 5th line/row.
hey, really cool video! thank you very much! I have one question for the results of line 21. (Frequency analysis) So if we do not count the words with that function, what are the numbers in the [...] brackets tell me?
how to know the frequency of some particular words. for example I want to know the frequency of certain words like "Technology, blockchain, peer to peer transaction, new systems etc '
Thanks 17Adamovic. If you watch parts 2 & 3 of text analytics on PDF, you will see additional ways to analyze the content on page level, document level and filter by words. Kindly see the following titles: How to perform Text Analytics on PDF Documents in R? Multiple PDF Analysis in R
@@DataCentricInc as im brand new to learning R, and need it to do some research work for a professor, I've been watching and learning from your videos! I did watch the other parts, but I don't believe the search/count of a specific word was shown, unless I missed it. You show us how to filter or search for the most frequent words, but I was wondering if we could simply count the amount of a specific word, like "cyber"
@@17Adamovic Kindly see code below that you can use to filter the frequency of words in the Term Document Matrix. Hope this helps :). inspect(opinions.tdm[c("cyber"),])#search for specific words
@@DataCentricInc do you have a video on the cleaning code that needs to be done to avoid missing out on the search words with " ' " in them (like, cyber's)? When i apply the cleaning code in your current videos such as removePunctuation, stopwords, tolower, stemming, removeNumbers, bounds, and then search for a specific word, it still avoids the words with any apostrophes in them, even if i change the search term to say "cybers" since the previous coding might remove the apostrophe
Great Work Mam, i have one thing if you help me out on that, for example, we took only a specific term from the pdf and then want to analyze for that specific term. Is it possible
The missing thing in Data Centric Inc series of tutorial is annotaion of Function words and content words as pre-processing steps, it will be highly pleasing to get your insights and hands-on annotaion and removal of function words prior to analysis.
Hello thanky for the great videos!! I have some issues with line 4 its not working. I sent you an mail hopefully you can help me. The error is: Error in lapply(files, pdf_text) : object 'files' not found
Hi ER, it is difficult to diagnose the problem just from this error, ensure you run the line that create the files variable just to so be sage because that could cause an error as well.
Thanks for your feedback Kripa however I need a little more clarity on this request. Is it that you want to search for a PDF file on the web using R and then perform text mining on the results?
Could you please make a video about how to scrape, clean, and visualize data from within tables in a pdf using R? Preferably not a video that uses the tabulizer library or family of libraries. Only pdf tools please.
Your english is very clear Thanks
Madame, you are one of the best teachers I have seen...well done! Thanks so much for these videos.
You are welcome Carlos
This video is excellent. You have a tremendous talent for teaching!
Thank you 😊
THANKS FOR THE TUTORIALS... I HAVE A QUESTION: I need to apply OCR on pdfs before starting to analyze them do you have a tutorial about this issue?
Thank you very much. I have a problem. When I run the Corpus function to create the pdfdatabase, I get the following error: PDF error: Unknown Metadata type: 'XMP'. Could you please help me with that?
How do you search for individual specific terms, rather than frequently used terms? Thanks!
You are a great teacher! Such clear explainations. Thank you so much!
You're very welcome Rebecca! Glad it was helpful.
i tried lots of time by creating different project but always object database not found. what I will do when I run this pdfdatabase
Very helpful content, thanks for sharing
Thank you Kemal😊
Fantástico, thanks, i search skill work most pdfs, obrigado, from Brazil
Thank you Carlito
really you are great madam.
Thank you
Thank you ma'am
Kindly share the link to download the PDF so that I can repeat what you did at home.
Thanks in anticipation.

Hi Zacha B, you can type the following line to install the tm library: install.packages("tm")

Very good tutorial!!
Thanks 😊
I look forward to working with you for my PhD thesis. Hope you will respond soon.

Hello, thank you for your videos, they help us so much! Please how many papers we can analyze? We can analyze more than 3 PAPERS ??
You are welcome JustDrawing. You can analyze more than three. I have done up to 30 and you could probably do more.
