Hey guys
I am trying to go through a number of text files and I want to find all of the unique words and save them in a different text file (dictionary.txt) . After doing that, I want to compare all of the original documents and replace the words with the position of the words from dictionary.txt. Can anyone help me find some code examples that I can follow?
Say - dictionary contains 'Goat', 'Tommy', 'Bag', 'is', 'wild', 'a' Txt file 1 has - Tommy is a wild goat would become 24651
This is the code I have written so far. I cannot save the file.
clc
clear all
close all
fid = fopen('test.txt');
fgetl(fid);fgetl(fid); %we are gettin rid of the first 2 lines of the thing using fgetl
words = textscan(fid,'%s'); %we are text scanning the words from the document
status = fclose(fid)
lower(words{1,1}) %we are making all of the words lowercase
%here we are getting rid of all of the words which are one letter
for i = 1:numel(words{1,1})
if size(words{1,1}{i,1}, 2) == 1
words{1,1}{i,1} = ' ';
end
end
%%Get rid of all Non words(Numbers)
for i=1:numel(words{1,1})
ind = find(isstrprop(words{1,1}{i,1}, 'digit') == 1);
words{1,1}{i,1}(ind)=[];
end
for i=1:numel(words{1,1})
ind = find(isstrprop(words{1,1}{i,1}, 'alphanum') == 0);
words{1,1}{i,1}(ind)=[];
end
mkdir('output')
dictionary = fopen('dict.txt','w')
[words,frequency,position] = unique(words{1,1})
words = lower(words)
fid2 = fopen('dict.txt','w')
fwrite(fid2,words)

fprintf(fid2, '%s\n', words{:});
fclose(fid2)
