Natural Language Pythoning

Join NYC Python for a night of talks about loosely and dynamically typed languages with no discernible syntax rules!

Talks:

Slicing Up Words with Python - Steven Butler

Morphological segmentation is the process of splitting words up in their component morphemes (smallest grammatical units in a language*) in order to improve a variety of downstream NLP tasks, like machine translation and keyword search. For well-resourced languages with well-understood morphological patterns (like English), this is no longer very much of an issue, but for low-resource languages (those that don't have a lot of NLP research done on them), this problem is a lot harder. I'll demonstrate a Python library called Morfessor (an interface to a family of unsupervised segmentation algorithms developed by a research team in Finland) that has been used for working on low-resource language segmentation, and talk a little bit about my work, which is trying to improve segmentation accuracy when morphological patterns get exotic**.

* e.g., 'words' -> ['word', 's']
** infixation, partial reduplication, etc.

Jargon-term Extraction by Chunking - Angus Grieve-Smith, Adam Meyers

One major subfield of NLP, Information Extraction (IE), deals with finding needles in haystacks - taking a huge corpus of text and pulling out the most important parts, like frequently used entities (people, places or things) and the relations between them.  At NYU we developed methods for extracting jargon terms - terms that are used more frequently in particular fields than in general writing.  These methods involved a combination of close annotation of the documents, algorithms to find particular patterns, and machine learning to extend the annotation.

N-grams: What they are and what you can do with them - Max Schwartz

I will touch on text classification, text generation, and how N-grams can fit in to solutions to problems like word segmentation and part-of-speech tagging.

    Very sorry disturbing. I want a free link learning python from beginning. PDF or any. I want to become professional programmer and lots of people suggested me start with Python. I can't find any good source for learning in Afghanistan.

    Be sure to release your RSVP or get off the waitlist if you can't make it so that people at the top of the waitlist can get in. Note that we're paying closer attention to no-shows. Thanks, everyone!
