Press release VU University on NewsReader: Join the hackathon!

VU-hoogleraar en Spinozawinnaar Piek Vossen presenteert NewsReader
Ontdek ook zelf deze nieuwe technologie die het nieuws leest

In 2013 startte Piek Vossen (hoogleraar computationele lexicologie), samen met onderzoekers in Trento en San Sebastian en met de bedrijven LexisNexis (NL), SynerScope (NL) en het Engelse ScraperWiki het NewsReader project om een computerprogramma te ontwikkelen dat dagelijks het nieuws ‘leest’ en precies bijhoudt wat, wanneer, waar gebeurd is in de wereld en wie er bij betrokken is. Het project kreeg hiervoor 2,8 miljoen euro subsidie van de Europese Commissie.

SynerScope‘s visualization: extraction from 1.26M news articles

Nieuws lezen in vier talen
In afgelopen 3 jaar hebben de onderzoekers een technologie ontwikkeld om de computer automatisch het nieuws te laten lezen in vier talen. Uit miljoenen krantenartikelen is nu een doorzoekbare database gemaakt waarin duplicaten zijn ontdubbeld, complementerende informatie uit verschillende berichten op een slimme manier samengevoegd is en is de informatie verrijkt met fijnmazige types zodat je niet alleen op persoonsnamen zoals ‘Mark Rutte’ en `Diederik Samsom’ kunt zoeken, maar ook op entiteiten van het type ‘politicus’.

Presentatie NewsReader
Op dinsdagmiddag 24 november 2015 organiseert de onderzoeksgroep Computational Lexicology & Terminology Lab (CLTL) van Piek Vossen een workshop waarin de eindresultaten van het project gepresenteerd worden. Ook zijn er diverse sprekers die hun visie op het project geven, zoals VU-hoogleraar Frank van Harmelen (Knowledge Representation & Reasoning), Bernardo Magnini, onderzoeker bij FBK in Trento en Sybren Kooistra, data journalist bij de Volkskrant en medebedenker en hoofredacteur van Yournalism, het platform voor onderzoeksjournalistiek.

Doe mee met de Hackathon!
Op 25 november kunnen gebruikers zelf aan de slag met de nieuwsdatabase die is opgebouwd uit miljoenen krantenartikelen. Meer informatie en aanmelden.

NewsReader Workshop & Hackathon, Nov. 24—25 2015

Car Wars: Industrial Heroes Going Down Fighting

On 24 and 25 November 2015, we will showcase the NewsReader project and invite you to come explore our technology and its results yourself during our NewsReader Workshop and Hackathon.

Event Details
We have developed a powerful new tool called ‘NewsReader’ which utilises natural language understanding and semantic web technology. This helps you to better understand the interactions between companies and key individuals, derived from news articles.
Our dataset encompasses 12 years of news charting the struggle of automotive players to rule the global market, to satisfy the expectations of the shareholders, and their suffering from the financial crisis and new economies: industrial heroes going down!

The Workshop
Tuesday 24 November 2015, 14:00 – 18:00 Amsterdam Public Library
In this workshop, we will bring together start-ups, companies, researchers and developers to present and discuss the NewsReader project, the technological domains it draws from and future applications for these technologies.
This afternoon will feature invited talks, demos, a panel discussion and a networking reception.
Confirmed Speaker:
Prof. dr. Frank van Harmelen, Vrije Universiteit Amsterdam. Frank van Harmelen is a professor in Knowledge Representation & Reasoning in the AI department (Faculty of Science) at the Vrije Universiteit Amsterdam. After studying mathematics and computer science in Amsterdam, he moved to the Department of AI in Edinburgh, where he was awarded a PhD in 1989 for his research on meta-level reasoning.

The Hackathon
Wednesday 25 November 2015, 10:00 – 18:00 Amsterdam Public Library
In June 2014 and January 2015 we ran several hackathons in both London and Amsterdam in which NewsReader enabled the attendees to pull out networks of interactions between entrepreneurs, politicians, companies and thoroughly test drive our technology. This November, we’re releasing a new version of our processing pipeline and we’re scaling up to 10 million processed news articles from sources about the automotive industry to obtain a searchable database of the news. At the hackathon, you can play with this dataset and explore the processing pipeline.
The global automotive industry has a value in the order of $1 trillion annually. The industry comprises a massive network of suppliers, manufacturers, advertisers, marketeers and journalists. Each of these players has his/her own story, often with unexpected origins or endings; one day you may be CEO of a big car company, the next you are out and making pizzas. With NewsReader, you can uncover these stories to reconstruct the past.

This event may be of interest to you if:
You’re interested in natural language processing and/or semantic web technology
You’re a data journalist on an automotive desk;
You’re an analyst sifting daily news looking for information on your company or on competitors;
You’re a data analyst looking to understand how your customers operate their supply chain
You’re an analyst trying to find secondary events that could influence an investment decision;
You’re interested in visualising big data

Attendance is free, but please register by Sunday 22 November 17:00 CET. .

NewsReader helps you find a needle in a haystack.

VENI grant for Antske Fokkens

Antske Fokkens received a VENI grant for her proposal Reading between the lines. The project aims at identifying so-called implicit perspectives in text.

Perspectives are conveyed in many ways. Explicit opinions or highly subjective terms are easily identified. However, perspectives are also expressed more subtly. For instance, Nick Wing argues that media describe white suspects (e.g. brilliant, athletic) more positively than black victims (e.g. gang member, drug problems). Ivar Vermeulen (p.c.) observes in a small Dutch corpus that Moroccan perpetrators are easily called thieves (implying generic behavior), where other perpetrators from Dutch only stole something (implying incidental behavior). These observations are anecdotal, but reveal how choices concerning what information to include or how to describe someone’s role may display a specific perspective.

This project will investigate how linguistic analyses may be used to identify these more implicit ways of expressing perspectives in text. This research will be carried out in three stages: First, large scale corpus analyses will be applied to identify distributions of semantic roles (what entities do) and other properties assigned to them (their characteristics). In the second stage, generic participants will be linked to the semantic role they imply (e.g. a thief will be linked to the perpetrator of stealing). With these links, we can investigate whether thieves are described differently from people who steal. In the third stage, emotion and sentiment lexica will be used to identify the sentiment associated with descriptions of people enabling research that investigates whether people are depicted positively or negatively.

The research is carried out in the context of digital humanities and social sciences. Evaluation and experimental setup will be guided towards identifying differences in perspective between sources. In addition to correctness of linguistic analyses (intrinsic evaluation), the possibility of using the method for identifying changes in perspective over time (historic research) or differences in perspective between sources (communication science) will be investigated.

VU University scientists cluster responses NWO’s National Research Agenda

Led by Piek Vossen, a group of scientists at VU University automatically divided 11,700 questions from NWO’s National Research Agenda into clusters. On the basis of language technology and mathematical equations of the most important words, there were slightly over 60 clusters of questions found which at their turn were classified in a few hundred sub-clusters. Important themes are health and energy, but also big data, art, and sports. NWO is happy with this analysis. The VU Topic Browser allows NWO to quickly and efficiently process the large number of responses.

Netherlands Organisation for Scientific Research (NWO): Dutch Science Agenda
Scientists determine the Dutch Science Agenda together with companies, civil society organisations and interested citizens. The agenda consolidates the themes that science will focus on in the coming years. What are the favourable opportunities for Dutch science and how can science contribute to finding solutions for societal challenges and making the most of economic opportunities?

As part of the QuPiD2 research team, the candidate will develop 1) a perspective model for representing the subjective relation between the source of information and the statements in it, and 2) software to detect such interpersonal communication layers and perspectives from text. The project will transform big unstructured text data into deep data that show the emotions, opinions and view points on the changing world. It will reveal the social networks and dynamics within trust networks that influence our world views.

1. Studying existing models for handling provenance, attribution, sentiments, opinions and emotions as expressed in text.
2. Developing an overarching perspective model for representing the subjective relations between sources and their statements. The model will initially be based on textual data but should show the capacity to model perspectives on any type of (big) data.
3. Using semantic web standards, e.g. RDF, SPARQL, to represent and access the data within the project
4. Studying existing NLP approaches to detect perspective relations in texts. Both English and Dutch texts will be considered.
5. Developing a machine-crowd empowered processing of textual sources for populating the QuPiD2 model
6. Creating data sets for training and evaluation through expert annotation and crowd annotation.
7. Developing new components and approaches to obtain the perspective values within the model from textual data.
8. Evaluate the components against the data sets developed and within an application environment.
9. Collaboration with the QuPiD2 program research team
10. Publish the results of the work as scientific articles in high ranked journals and conferences, as well as present the work at relevant scientific venues
