Generally, you can install them by means of the MATLAB Add-Ons Manager or through:

matlab.addons.install(‘Toolbox Name’);

2. Get Familiar with the Text Analytics Toolbox

You must be familiar with the major functions that are offered by the Text Analytics Toolbox. The following are some main functions:

• bagOfWords
• word2vec
• tokenizedDocument
• tfidf

3. Choose a Project Topic

An NLP problem has to be chosen in such a manner in which you are intrigued in addressing like text categorization, topic modelling, sentiment analysis, or text summarization.

4. Collect or Create a Dataset

Focus on gathering or developing a dataset on the basis of your project topic:

• Publicly Available Datasets: Typically, Yelp Reviews, BBC News, IMDb Reviews, Kaggle datasets are determined as publicly accessible datasets.
• Custom Dataset: By means of employing web scraping approaches or APIs such as Twitter API, obtain text data from websites or blogs.

5. Preprocess the Text Data

Normally, the process of eliminating stemming, tokenization, stop words, and lemmatization are encompassed in the preprocessing step.

Example Code:

% Load your text data

textData = [“I love MATLAB. It is great!”, “MATLAB is useful for engineers.”];

% Tokenize and preprocess the text data

documents = tokenizedDocument(textData);

documents = removeStopWords(documents);

documents = normalizeWords(documents, ‘Style’, ‘stem’); % Stemming

% Training options

options = trainingOptions(‘adam’, …

‘MaxEpochs’, 5, …

‘MiniBatchSize’, 32, …

‘Shuffle’, ‘every-epoch’, …

‘Verbose’, false);

% Train the LSTM network
