txt_clean_word2vec

a character vector in UTF-8 encoding

logical indicating to use <code>iconv</code> to convert the input from UTF-8 to ASCII. Defaults to TRUE.

ascii

logical indicating to keep only alphanumeric characters. Defaults to TRUE.

alpha

logical indicating to lowercase <code>x</code>. Defaults to TRUE.

tolower

logical indicating to trim leading/trailing white space. Defaults to TRUE.

trim

Standardise text by<ul>
<li>Conversion of text from UTF-8 to ASCII</li>
<li>Keeping only alphanumeric characters: letters and numbers</li>
<li>Removing multiple spaces</li>
<li>Removing leading/trailing spaces</li>
<li>Performing lowercasing</li>
</ul>

Learn vector representations of words by continuous bag of words and skip-gram implementations of the 'word2vec' algorithm.
The techniques are detailed in the paper "Distributed Representations of Words and Phrases and their Compositionality" by Mikolov et al. (2013), available at <arXiv:1310.4546>.
