… as an entity in the Google Knowledge Graph!

Which is funny, because “emerging entities” were the main topic of my PhD Thesis [1]. With my co-authors I’ve published research on:

1. Learning how to recognize “out-of-knowledge base” entities emerging on social media [2]
2. How our collective memory is formed through “emerging entities” on Wikipedia [3], and more generally
3. Entity retrieval and ranking [4] where Google’s so-called “Knowledge Panels” often served as examples…

(FYI: I’m not sure how I ended up there, the metadata seems to be coming from Google Scholar)

I was invited by UvA’s Information, Communication and the Data Society (ICDS) to participate in a panel at the Conference on Privacy and Data Protection, which was focused on AI.

The recording of the panel is now online, watch me telling a room full of (highly) privacy-aware (and cookie-averse) people that Cambridge Analytica nudging people to “politically activate them” with tailored information can be a “democratic good” 😅.

See the recording below:

For more information, see CPDP’s page of the panel.

For the Media Perspectives (“platform for media & innovation”) newsletter I wrote a column on the future of media & AI: Algoritmewijsheid. Read it below (in Dutch):

Enjoyed giving a lecture at the SIKS Course “Advances in Information Retrieval” at the Mitland Hotel in Utrecht. I also pitched DIR 2019 😅 (as evidenced by the picture above from Arjen). See my slidedeck below!

This talk is loosely based on (part of) the talk I gave at the ACM RecSys Summerschool, but I added a few slides on dealing with implicit feedback (= clicks), and popularity bias.

With Daan Odijk I gave a lecture + hands-on workshop at the ACM Summer School on Recommender Systems in Gothenburg, Sweden on RecSys in the Media Industry: Relevance, Recency, Popularity, and Diversity.

For it, we had a long (90+ min) lecture combining insights, experiences, and projects from our work at RTL and Blendle (Daan), and FD Mediagroep (me).

In addition, we did a small hands-on workshop, implementing a content-based re-ranker for WikiNews.

Update (28/1/2020): Oberon’s thesis was accepted and will be published at the IEEE 45th International Conference on Acoustics, Speech, and Signal Processing (ICASSP 2020), to be held May 4-8 in Barcelona, Spain! The submission is co-authored with Klaus Lux and myself.

Oberon Berlage recently successfully defended his MSc. thesis (title above!) for the Data Science Master at University of Amsterdam, and graduated with a whopping 9!

He’s the first academic offspring of our AI Team @ FD Mediagroep, and worked on BNR SMART Radio‘s segmenter. Oberon improved our text-based segmenter by adding audio embeddings, improving the F1 score with +32%!

His thesis is now online, check it out at: http://scriptiesonline.uba.uva.nl/document/673254

Yesterday BNR SMART Radio won two Dutch Interactive Awards (DIA 2019) Awards! We were nominated together with Elastique, the folks who designed the UX/interface of our BNR SMART Radio app which you can download here (or in your app stores, both Android/iOS)!

🥇 Content

We won Gold in the category “Content”. Why, you may ask?

“Finally a reason to listen to Radio in general, and BNR in particular. Because advertising is absent and topics are tailored to the personal taste of the listener, who can search in a targeted way and express appreciation for a broadcast through a thumbsup, they reach new target audiences online.”

🥈 Disruptor

Next to this, we also won the Silver DIA2019 Award in the category “Disruptor”!

“In a world where radio has never deviated from the linear model, the jury finds this very disruptive. SMART Radio provides a personal radio experience and possibly a new revenue model in the long term. The jury members find the potential of the underlying strategy even more impressive. What if BNR joins forces with FD Mediagroep and combines the work of both parties in this? The jury sees all kinds of opportunities to fit in new forms of advertising (or to omit them). The collaboration between the agency and the media company has resulted in something that has never been seen before.”

Current standing

For who has trouble keeping track 😅, these are the awards we won with SMART Radio:

🏆 Marconi Online Award
🏆 AMMA Award (with SMART Journalism)
🏆 DIA2019 Award, category: Content
🥈 DIA2019 Award, category: Disruptor

After winning the Marconi award for radio innovation, yesterday we picked up the AMMA Award for Media Innovation for our news personalization efforts at FD Mediagroep (both SMART Journalism for Het FD and SMART Radio for BNR Nieuwsradio)!

It’s really great to see that our current investment into AI and innovation seems to resonate with the outside world 🤖. And I am really happy to be with a company that sees this development as such an important direction that we are able to work with a big and talented team of data scientists, interns, engineers, and product folks 🤓

I wrote a response on recent coverage around the alleged ‘promotion’ of anti-vax books by bol.com, suggesting it is due to “influential, steering, algorithms.” In this piece I state it’s not an issue of algorithms, but of long-tail, obscure, content. My response was published in Het Parool, as an edited letter. Read the original, unedited piece (in Dutch) below.

Together with Anne Schuth and Daan Odijk I’ll be co-organizing The Dutch-Belgian Information Retrieval workshop (DIR 2019). At DIR 2018, we sat down during lunch and came up with the following plan:

#DIR2019 will try something new. Top ranked IR papers from WWW, WSDM, CIKM, NeurIPS, RecSys, CHI, CHIIR, KDD, ECIR, ACL, EMNLP (in no particular order, open to suggestions) with authors in NL & BE will be invited to present their work in a lightning talk⚡#DIR2018

— DIR 2019 – Lightning talk Edition (@dir_2019) 23 november 2018

We also decided on a date: November 29, 2019!

For now, the most import work is done (designing a logo, and setting up our Twitter account ;-)). Stay tuned for more, later! And follow @dir_2019 for now ⚡.
