<dd><p>Load text files with categories as subfolder names.</p>
<p>Individual samples are assumed to be files stored a two levels folder
structure such as the following:</p>
<blockquote>
<div><dl class="simple">
<dt>container_folder/</dt><dd><dl class="simple">
<dt>category_1_folder/</dt><dd><p>file_1.txt
file_2.txt
…
file_42.txt</p>
</dd>
<dt>category_2_folder/</dt><dd><p>file_43.txt
file_44.txt
…</p>
</dd>
</dl>
</dd>
</dl>
</div></blockquote>
<p>The folder names are used as supervised signal label names. The individual
file names are not important.</p>
<p>This function does not try to extract features into a numpy array or scipy
sparse matrix. In addition, if load_content is false it does not try to
load the files in memory.</p>
<p>To use text files in a scikit-learn classification or clustering algorithm,
you will need to use the <a class="reference internal" href="../classes.html#module-sklearn.feature_extraction.text" title="sklearn.feature_extraction.text"><code class="xref py py-mod docutils literal notranslate"><span class="pre">text</span></code></a> module to
build a feature extraction transformer that suits your problem.</p>
<p>If you set load_content=True, you should also specify the encoding of the
text using the ‘encoding’ parameter. For many modern text files, ‘utf-8’
will be the correct encoding. If you leave encoding equal to None, then the
content will be made of bytes instead of Unicode, and you will not be able
to use most functions in <a class="reference internal" href="../classes.html#module-sklearn.feature_extraction.text" title="sklearn.feature_extraction.text"><code class="xref py py-mod docutils literal notranslate"><span class="pre">text</span></code></a>.</p>
<p>Similar feature extractors should be built for other kind of unstructured
data input such as images, audio, video, …</p>
<p>If you want files with a specific file extension (e.g. <code class="docutils literal notranslate"><span class="pre">.txt</span></code>) then you
can pass a list of those file extensions to <code class="docutils literal notranslate"><span class="pre">allowed_extensions</span></code>.</p>
