Edit to make so that the code works with the latter added example data...
% read the file
data = readtable("dati_classificati.xlsx",'TextType','string');
% split each sentence into words, assuming that spaces are used as delimiter...
cell_text = arrayfun(@(x) data.text(x,:),1:size(data.text,1),'UniformOutput',false)';
cell_text = cellfun(@(x) split(x,' '), cell_text,'UniformOutput',false);
% count the number of words in each sentence
numWords = cellfun(@numel, cell_text);
% expand the labels to match the number of words for each sentence
expandedLabels = repelem( data.label ,numWords);
% gather the words in 1 big string array
expandedWords = vertcat(cell_text{:});
% list a few words to count the frequency...
MyWords = ["strada" "il" "Via" "donne" "della"];
% allocate a table for the results
varTypes = ["string","double","double"]; % data type for each column
varNames = ["Words","Ones","Zeros"]; % variable name for each column
MyResult = table('Size',[numel(MyWords) 3],'VariableTypes',varTypes,'VariableNames',varNames);
MyResult.Words = MyWords(:);
% count the labels for each word
for i = 1:numel(MyWords)
currLabels = expandedLabels( contains(expandedWords,MyResult.Words(i)) );
MyResult.Ones(i) = sum(currLabels==1);
MyResult.Zeros(i) = sum(currLabels==0);
end
% display the results
MyResult
