IMG_20160420_194059 Natural Language Processing with Python: cleaning the text
The second of the five Natural Language Processing with Python meetings by Women Who Code. Diana, our presenter, introduces the "Cleaning" step of the today's agenda, which means: eliminating punctuation from the text, eliminating stopwords, normalizing data (converting to lower case), and tokenizing words.
Then we ventured deeper into natural language processing to discuss where and how it is used, including such fields as sentiment analysis. Diana talked about challenges present in those fields, such as for example determining similarity between concepts. We need to be able to handle that so as to extract accurate meanings from texts. This is where ontologies can be handy.
