This is a Keynote talk from the Oxford Internet Institute's Symposium "Social Science and Digital Research: Interdisciplinary Insights", held in Oxford on 12 March 2012. The research field of webometrics encompasses various forms of web-based link and text analyses. Webometric studies have included large scale analyses of social network sites and social web sites like Flickr, Twitter and YouTube, as well as areas of the traditional web, such as university websites. Webometrics began in 1997 within the discipline of Library and Information Science (LIS) in response to the recognition that commercial search engines could turn the Web into a large database f Wales; http://creativecommons.org/licenses/by-nc-sa/2.0/uk/

Description

Taking as its starting point the works of one of Britain's most respected, prolific—and funny—living dramatists, this seminar will explore a wide range of knowledge in fields such as math, philosophy, politics, history and art. The careful reading and discussion of plays by (Sir) Tom Stoppard and some of his most compelling contemporaries (including Caryl Churchill, Anna Deveare Smith and Howard Barker) will allow us to time-travel and explore other cultures, and to think about the medium of drama as well as one writer's work in depth. Some seminar participants will report on earlier plays that influenced these writers, others will research everything from Lord Byron's poetry to the bridges of Konigsberg, from Dadaism to Charter 77.

Description

The final Presidential debate of 2016 was as heated as the previous two—well demonstrated by the following name-calling exchange: CLINTON: ...[Putin would] rather have a puppet as president of the United States. TRUMP: No puppet. No puppet. CLINTON: And it's pretty clear... TRUMP: You're the puppet! CLINTON: It's pretty clear you won't admit ... TRUMP: No, you're the puppet. It is easy to form our opinions of the debate and on the differences between the Presidential candidates on excerpts like this and memorable one-liners. But are small extracts representative of the debate as a whole? Moreover, how can we objectively analyse ...

Description

Below, I discuss and analyse pre-processing decisions in relation to an often-used application of text analysis: scaling. Here, I?ll be using a new tool, called�preText�(for R statistical software), to investigate the potential effect of different pre-processing options on our estimates. Replication material for this post�may be found on my GitHub page. Feature Selection and Scaling Scaling algorithms rely on the bag-of-words (BoW) assumption, i.e. the idea that we can reduce text to individual words and sample them independently from a ?bag? and still get some meaningful insights from the relative distribution of words across a corpus. For the demonstration below, ...
