Talk 1: Brian Carter on Text mining project based on Pillreports.net - 45 mins

Pillreports.net is an on-line database of reviews of Ecstasy pills. In consumer theory illicit drugs are experience goods, in that the contents are not known until the time of consumption. Websites like Pillreports.net, may be viewed as an attempt to bridge that gap, as well as highlighting instances, where a particular pill is producing undesirable effects.

This talk will present the experiences and insights from a text mining project using data scraped from the Pillreports.net site. The setting up and the benefits, ease of using BeautifulSoup package and pymnogo to store the data in MongoDB will be outlined.A brief overview of some interesting parts of data cleansing will be detailed.
Insights and understanding of the data gained from applying classification and clustering techniques will be outlined. In particular visualizations of decision boundaries in classification using ""most important variables"". Similarly visualizations of PCA projections for understanding cluster separation will be detailed to illustrate cluster separation.

The talk will be presented in the iPython notebook and all relevant datasets and code will be supplied. Python Packages Used: (bs4, matplotlib, nltk, numpy, pandas, re, seaborn, sklearn, scipy, urllib2)"

Talk 2: Using PyKE Rule Engine in a Django system for making decisions - 15 mins

Brief overview of rule engines / expert systems; Practical use of rule engines; Existing options for rule engines in Python; Pro’s and con’s of PyKE; practical tips of using PyKE; considerations when incorporating a rules engine into an existing system, overview/architecture of an existing Django based system that uses PyKE.

Talk 3: "Mixing multiprocessing and threads in the UNIX environment: DOs and DONTs (mostly DONTs) - 45 mins

The subject of the presentation are the problems which arise when mixing threading and multiprocessing in Unix from the point of view of the Python developer. Some general concepts about the Unix APIs are refreshed, then we move and see how these are used inside Python and what problems result when deciding to use threads."
