February 4, 2015, NLTK meetup recap
On Wednesday, February 4th, our monthly meetup took place at TechHub Riga. Pizza and cookies were provided courtesy of EGlobal, who have a bunch of pythonistas here in Latvia.
NLTK is a leading platform for building Python programs to work with human language data. It provides easy-to-use interfaces to over 50 corpora and lexical resources such as WordNet, along with a suite of text processing libraries for classification, tokenization, stemming, tagging, parsing, and semantic reasoning. Good starting points would be NLTK Wiki and the NLTK online book, which contains a lot of examples.

The evening closed with a discussion about SQLAlchemy sessions when you want to reuse code between interfaces like Flask and console applications. In this use case the Flask-SQLAlchemy extension won't cut it, you have to roll your own code. If you're not careful, this can lead to serious bugs like sharing information between users. So, before writing code involving sessions, RTFM and consult experts. If you are one of the experts, then propose a talk, we would like to hear your opinions and advice.
- February 18th 19:00, first ever Python Latvia monthly workshop at The Mill.
- March 4th 19:00 next meetup at TechHub Riga.
