Stimuleringsfonds voor de Journalistiek published an article on ‘robo-journalism’, where I say something about the SMART Journalism project we are doing at FDMG, which involves personalization and summarization of newspaper articles. Read it here! (pdf). Snippet:

Door introteksten te personaliseren, kun je meer doelgroepen bedienen.’ Bij het genereren van gepersonaliseerde intro’s op basis van artikelen, komt behoorlijk wat techniek kijken, vertelt David Grauslead data scientist van het project bij het FD. ‘In de robotjournalistiek wordt nu vooral gewerkt aan het omzetten van gestructureerde data naar teksten. Wat wij willen is teksten maken op basis van door mensen geschreven teksten. Dat is behoorlijk cutting edge. We hebben daarom ook nauwelijks voorbeelden waar we ons op kunnen baseren.’

My debut on national TV ;-)! Denktank is a TV show where youngsters explore and think about how (current day) technology will affect them in the future. In this episode I explain some of the mechanisms behind algorithmic personalization.

Stream the episode at NPO.nl (the part with me starts at about 05:00), or see the website of Human for more information on the episode.

Featured in FD on the value of (personal) data

In today’s edition of Het Financieele Dagblad, I am quoted in an article on the value of (personal) data titled “Wanneer je gegevens geld waard zijn”;

De kennis die met die cookies wordt verzameld, wordt vervolgens verkocht aan nog eens tientallen bedrijven die daarmee hun reclameboodschappen gericht kunnen afvuren. ‘Waar je ook komt op het web, je laat altijd digitale sporen na’, zegt David Graus, die twee weken geleden promoveerde op dit onderwerp aan de Universiteit van Amsterdam. ‘Uit al die sporen voorspellen de bedrijven je gedrag en op basis daarvan plaatsen ze een advertentie.’ […]

De mogelijkheden met data gaan verder, stelt Graus. Stel dat op basis van gedrag van vrienden, familieleden, likes, posts en zoekopdrachten wordt geconcludeerd dat je rookt. Terwijl je dat zelf nooit hebt aangegeven. ‘Daarmee geef je privacy weg’, aldus Graus.

It has come to my attention that the nrc.next article I wrote with Maarten de Rijke on the lack of neutrality of algorithms is mentioned in Maurits Martijn & Dimitri Tokemetzis’
“Je hebt wél iets te verbergen” book on privacy, which you can order here.

Tekstblad (a magazine for text professionals) contains an interview with Hans Henseler and myself, on the “Semantic Search for E-Discovery” project I have been involved with during my PhD. The title loosely translates to “Searching for truth in 11.5M documents.” (click the image for the PDF).

A few weeks ago, I took the initiative and participated in a Apache Spark workshop at SURF. As part of SURF’s year report, I was interviewed to comment on the workshop and talk a bit about my own research. SURF published the article recently: read it here! A small outtake below:

One of the participants was David Graus, who conducts research in the field of digital forensics. As a PhD student, he is involved with the ‘Semantic Search in E-Discovery’ project, which was set up in collaboration with the Netherlands Forensic Institute (NFI) and the Dutch Fraud Squad (FIOD).

‘We develop programs or algorithms that help analysts search for digital evidence in documents,’ says David. ‘Analysts are currently doing a lot of this manually, by getting hold of a number of computers, for example, and browsing through the files. They look at the email files to find out who was in contact with whom, and what they discussed in their emails. We are trying to automate this process.’

BètaBreak is a monthly panel discussion in the University of Amsterdam’s Science Park main hall, where guests speak about current topics in science. I am invited to join a panel discussion titled “Behind the Algorithm” (subtitled: “What the Internet hides from you”) on algorithms, personalization, filtering and the filter bubble, together with Joost Schellevis and Manon Oostveen. Wednesday! See the video + flyer below.
