The igraph library for complex network research

The igraph library for complex network research
June 24, 2015 Release Notes This is a new major release, with a lot of UI changes. We tried to make it easier to use, with short and easy to remember, consistent function names. Unfortunately this also means that many functions have new names now, but don't worry, all the old names still work. Apart from the new names, the biggest change in this release is that most functions that used to return numeric vertex or edge ids, return vertex/edge sequences now. We will update the documentation on this site, once the package is on CRAN and available for all architectures.

Main igraph repositories now: April 21, 2014 Some bug fixes, to make sure that the code included in 'Statistical Analysis of Network Data with R' works.

GraphChi can run very large graph computations on just a single machine, by using a novel algorithm for processing the graph from disk (SSD or hard drive).

S Routines for Social Network Analysis in the R Environment Most of which involve social network analysis, though a wee bit 'o other stuff is available as well.... Introduction and Caveats This page serves, as one might expect, to allow other researchers to access some of the data analysis tools I've developed in the S language. Category:LanguageBindings -> PySide EnglishEspañolMagyarItalian한국어日本語 Welcome to the PySide documentation wiki page. The PySide project provides LGPL-licensed Python bindings for the Qt. It also includes complete toolchain for rapidly generating bindings for any Qt-based C++ class hierarchies. PySide Qt bindings allow both free open source and proprietary software development and ultimately aim to support Qt platforms. The latest version of PySide is 1.2.1 released on August 16, 2013 and provides access to the complete Qt 4.8 framework.

Social Network Analysis About the Course Everything is connected: people, information, events and places, all the more so with the advent of online social media. A practical way of making sense of the tangle of connections is to analyze them as networks. In this course you will learn about the structure and evolution of networks, drawing on knowledge from disciplines as diverse as sociology, mathematics, computer science, economics, and physics. Pajek / How to: Convert Excel datasets into Pajek format Jürgen Pfeffer, from FAS.research, Vienna developed a program that converts Excel datasets into Pajek format: At the Pajek workshop in Portoroz I promised to send you the algorithms to convert Pajek files from an Excel dataset. Inspired by your program I made an executable windows program which imports the data from an Excel file and converts these data to a pajek file.

Requests and Responses — Scrapy 0.14.4 documentation Using FormRequest to send data via HTTP POST¶ If you want to simulate a HTML Form POST in your spider and send a couple of key-value fields, you can return a FormRequest object (from your spider) like this: spheres spheres [ english | español | portugués ] Spherical Surface of Dialogue Spheres shaped by dialogue, a net of semantical combinations. The richness of words consists in their relations with one another. Leon Festinger Leon Festinger (8 May 1919 – 11 February 1989) was an American social psychologist, perhaps best known for cognitive dissonance and social comparison theory. His theories and research are credited with repudiating the previously dominant behaviorist view of social psychology by demonstrating the inadequacy of stimulus-response conditioning accounts of human behavior.[1] Festinger is also credited with advancing the use of laboratory experimentation in social psychology,[2] although he simultaneously stressed the importance of studying real-life situations,[3] a principle he perhaps most famously practiced when personally infiltrating a doomsday cult. He is also known in social network theory for the proximity effect (or propinquity).[4] Life[edit] Early life and education[edit] Career[edit]

Weblogs Forum - Screen Scraping With Python Summary Web-enabling an old terminal-oriented application turns into more fun than expected. A blow-by-blow account of writing a screen scraper with Python and pexpect. I recently finished a project for a local freight broker. They run their business on an old SCO Unix-based "green screen" terminal application. They wanted to enable some functionality on their web site, so customers could track their shipments, and carriers could update their location and status. By the time the project got to me the client had almost given up on finding a solution. Text Network Analysis Text network analysis allows one to quickly visualize the meanings and agendas present within a text, live conversation, broadcast, or interview. Our method is different to semantic network analysis. Instead, we focus predominantly on the relationships and clusters of meaning present within the text, uncovering what we call the pathways for meaning circulation
