Text analysis: Most frequent terms and RCA of terms.

Note 1: term counts based on the label, alternative labels and the description of skills. Note 2: a RCA < 1 means that the term is less frequent among digital skills relative to all skills. Thus the term has a relative comparative ‘disadvantage’ describing digital skills. RCA (low advantage) for digital RCA between 1 and 5; RCA (mid advantage) for digital RCA between 5 and 10; and RCA (high advantage) for digital RCA greater than 10. Note 3: for the text analysis, we first tokenise the text, we then discard punctuation marks and stop-words such as ‘from’, ‘the’, and ‘further’, and finally, we apply a lemmatisation using Python NLTK package for Natural Language Processing (NLP).
