WOW! thank you i am trying to learn NLP through R for my thesis, and this was a brilliant explanation thank you!!
This is incredible! so much information explained in a very simple way. Thank you!
Short and very detailed explanation!
where does the value 30 come from in the write:ines(as.character(docs[[30]])) come from?
Wonderful tutorial! Thank you so much !

Is text mining similar to thematic analysis
Hi Josephine, Text mining, also referred to as text data mining, roughly equivalent to text analytics, is the process of deriving high-quality information from text. Thematic analysis is one of the most common forms of analysis within qualitative research. It emphasizes pinpointing, examining, and recording patterns within data.
i am getting this error
Error in Corpus(DirSource("F:/textmining")) :
could not find function "Corpus"
inspect(docs)
Error in inspect(docs) : could not find function "inspect"
i have installed packages nlp and tm
please resolve thank you
Hi Karthik, the way to solve this problem is to detach a library before using inspect() method for an object made with other library.
detach(package:tm, unload=TRUE)
then load the required libraries and use inspect() method. Hope this is helpful.
and how to analyze Reviews given in . CSV file?
Hey Priyanka, the read.csv command reads a CSV (Comma Separated Value) file from disk. Such files represent a table whose rows are represented by single lines in the files and columns are marked by a separator character within lines. Arguments of the command can be set to specify whether the CSV file contains a line with column names (header = TRUE or FALSE) and the character set.
where can I find the documents ?
Hi Tammam, kindly drop in your email id to help us assist you with the required documents for your referencing. Happy learning :)
what extension of file in TextMining folder?
Hi Priyanka, extension to be mined can be loaded into R from different source formats. It can come from text files(.txt),pdfs (.pdf),csv files(.csv) etc., but no matter what the source format is, to be used in the TextMining package it is turned into a “corpus”. Hope this is helpful!
Brilliant!
