Two workshops on web-crawling at UCLA

The International Institute and the UCLA Program on International Migration are proud to present:

Introduction to Hyphe: A new webcrawler for analyzing controversies

Monday, January 26, from 3 to 5 p.m.
Wednesday, January 28, from 3 to 5 p.m.

Both workshops in the Laboratory for Digital Cultural Heritage, in the Young Research Library Research Commons

Presented by Mathieu Jacomy, MédiaLab, Sciences Po, Paris

Working on controversies – whether related to immigration, the environment, or police behavior — can be greatly facilitated by crawling the websites maintained by actors involved in any controversy and thereby analyze their online connections.

These workshops are designed to introduce non-technical users to a new web crawler, Hyphe, designed so that researchers can control the building of a web corpus (by filtering and qualifying the websites to include in the corpus) while simultaneously providing  powerful tools capable of handling the huge amount of data available on the web.

Using modern and robust technologies such as Lucene, MongoDB, Scrapy, Twisted, Thrift, Domino.js, Sigma.js or Bootstrap, Hyphe can manage multiple corpora within each instance, bypassing crawling issues (redirections, cookies, javascript-only pages, …), handling multi-websites entities from the web interface, tagging the results, and so on…

Hyphe is easy to use.  Workshop participants will simply need a laptop equipped with a conventional web browser (Chrome, Firefox, etc) and access to the internet.  Depending on time and interest, the Wednesday workshop will also provide an overview of Gephi.
