In late February 2020, I found myself sitting at a table in the Interacting Minds Center with a diverse group of Aarhus University researchers discussing how to research the social and behavioural aspects of the emerging Covid-19 epidemic. The expertise of the other researchers spanned media and information studies, anthropology and ethnography, religious studies, political science, and computer science. I represented linguistics. At the time, Covid-19 had not (to our knowledge) reached Denmark, and it was still at least a week before the WHO would officially designate it a global pandemic. We suspected that this virus might have significant consequences for our lives, but we could never have imagined how much and how quickly.

Just weeks later, …

”I read your Facebook post and (I think) I know who you are”, part 2: A mini-experiment on author psychology assessment

minieksp

In part 1 on this blog, “A mini-history of author analysis”, I pointed out that attempting to draw conclusions about the author of a text based on traits of the text alone has a long tradition in forensics (identifying perpetrators or revealing forgeries), literary studies (authorship identification) and psychology (from psychoanalysis to modern customer/consumer behavior studies). In its modern, machine learning version, psychological author profiling is often based on the ”Big Five” model (see figure 1) going back to McCrae & Costa 1989.

But how do human readers decode and interpret concrete features of text as to its authors personality?

In order to find preliminary answers to this question, I performed a mini-experiment in my lesson on “Communicative …

”I read your Facebook post and (I think) I know who you are”, part 1: A mini-history of author analysis

Billede1

Attempting to draw conclusions about the author of a text based on traits of the text alone has a long tradition. It has been a topic of interest in forensics (identifying perpetrators or revealing forgeries), literary studies (authorship identification) and psychology (from psychoanalysis to modern customer/consumer behavior studies). In 15th Century Italy, Lorenzo Valla proved the forgery of the Donation of Constantine based on anachronistic word choice (8th, and not 4th, century A.D.) and poor grammar. Contending the authorship of certain texts previously attributed to Shakespeare goes back to the end of the 17th Century and builds on the philological methods stemming from biblical and classic studies, developed in the Renaissance period, analyzing language style (word choice and grammar).

Researchers hiding in fear of GDPR

GDPR – business or pleasure?

Do you remember GDPR (or, for mnemonic assistance, Gitte and Per)? This is one of three posts on the EU law that everybody feared last year: What did we think it was, what is it, and what effects has it had?

In the weeks before 25 May 2018, I received up to thirty e-mails a day (yes, I have too many accounts at webshops and social media) with similar text: “We are updating our Privacy Policy”.

Effects of GDPR

GDPR – business or pleasure?

Do you remember GDPR (or, for mnemonic assistance, Gitte and Per)? This is one of three posts on the EU law that everybody feared last year: What did we think it was, what is it, and what effects has it had?

When the EU legislation was announced, many researchers at my department were in doubt of exactly what to do (see also: What is GDPR? A compliance guide) — and after more than a year, still no general practice has emerged.

A survey of among my research colleagues in linguistics show highly individual solutions to the new law. Researchers of social media in particular are frustrated about how to interpret the law when
