#Keynote #DataScience #NLP #Python @epythonlab Natural Language Processing Natural language processing (NLP) is the field devoted to methods and algorithms for processing human (natural) languages for computers. NLP is a vast discipline that is actively being researched. Some examples of machine learning applications using NLP include sentiment analysis, topic modeling, and language translation. In NLP, the following terms have specific meanings: - Corpus: The body/collection of text being investigated. - Document: The unit of analysis, what is considered a single observation. Examples of corpora include a collection of reviews and tweets, the text of the Iliad, and Wikipedia articles. Documents can be whatever you decided, it is what your model will consider an observation. For the example when the corpus is a collection of reviews or tweets, it is logical to make the document a single review or tweet. For the example of the text of the Iliad, we can set the document size to a sentence or a paragraph. The choice of document size will be influenced by the size of our corpus. If it is large, it may make sense to call each paragraph a document. As is usually the case, some design choices that need to be made.

Open Datasets for Research During last week there were several news about newly open datasets for researchers. 1. Twitter opened “full history of public conversation” for academics (specifically, for academics): https://www.theverge.com/2021/1/26/22250203/twitter-academic-research-public-tweet-archive-free-access We can happily conduct researches about social networks graphs, users behavior and fake news (especially fake news🙃) without fighting with Twitter API. 2. Papers with code are now also Papers with Datasets: https://www.paperswithcode.com/datasets Not for only NLP, but for all fields structured for easy search and download.
