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.

The global automotive industry has a value of the order of $1 trillion annually.

The industry comprises a massive network of suppliers, manufacturers, advertisers, marketeers and journalists. Attracting and supporting the industry is a significant goal of industrial policy.

On January 21st 2015 we’re running an event which should be of interest if :-

  • 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

We’ve 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.

We’re processing 6 million news articles from sources around the world both general and specialist media to obtain a searchable database of the news on the automotive sector and you can play with at our Hack event.

Over summer we ran a Hack Day on news surrounding the World Cup. NewsReader enabled the attendees to pull out networks of interactions between politicians, football players and people in FIFA. Not only who they were interacting with but what they were doing.

Early analysis of the automotive data is giving us some interesting insights. For example, news stories between 2005 and 2009 reported that Porsche was buying an ever larger stake in Volkswagen, prompting speculations that Porsche would take over Volkswagen. However, in 2009 the tables turned and Volkswagen took a majority stake and eventually took over Porsche. Our system is able to discriminate between articles mentioning that Volkswagen was taking over Porsche and vice versa rather than simple co-occurrences that are generally found in aggregated news analysis systems. In the slipstream of this take-over, Wendelin Wiedeking, longtime Porsche senior executive, was fired from Porsche. In 2013 he opened the first of a chain of Italian restaurants. As we have a structured database in which similar events can easily be retrieved, it is a small effort to find out that Jürgen Schrempp, former CEO of DaimlerChrysler, also opened a restaurant after retiring from the car industry.

We are running an event in London on January 30th 2105 and if you cannot make the 21st in Amsterdam you may want to join us there.

Mini-seminar: Disambiguating entities and their roles in texts based on background knowledge

Dear all,

We cordially invite you to our mini-seminar “Disambiguating entities and their roles in texts based on background knowledge ” in which we will present our Master’s thesis topics and the current/future work. It will take place on Friday, December 12 from 10:00 to 12:00 in room C-121 (W&N Building).

An array of text processing tools is currently used to extract events, recognize and link entities, and discover relations between the two. We, Filip Ilievski and Chantal van Son, tackle these type of Natural Language Processing tasks by using background knowledge from lexical resources and the Semantic Web. The disambiguation of entities and their context is in the core of both approaches: Filip’s thesis aims to disambiguate them by determining their identity while Chantal’s thesis aims at disambiguating the roles they play in context. You can find the descriptions of both projects below.

Prof. Piek Vossen will kick-off the mini-seminar by depicting the background of the problem and presenting the existing approaches. Prof. Frank van Harmelen will conclude the event with a discussion on the integration of background knowledge in language processing.

Program:
10:00 – 10:15 Introduction by Piek Vossen
10:20 – 10:50 Towards a Dutch FrameNet-style Semantic Role Labeler (Chantal van Son)
10:55 – 11:25 Named Entity Disambiguation with two-stage coherence optimization (Filip Ilievski)
11:30 – 12:00 Closing remarks and discussion lead by Frank van Harmelen

Towards a Dutch FrameNet-style Semantic Role Labeler (Chantal van Son)
Semantic role labeling (SRL) is one of the key tasks in Natural Language Processing for deep text understanding. Because of its rich and fine-grained categorization of different conceptual scenarios and their specific semantic roles, FrameNet is a popular resource to serve as a basis for SRL systems in English. For Dutch however there is currently no FrameNet-like resource available that can be used to train a SRL system, and creating such a resource usually takes a great deal of expensive manual effort. This study investigates how existing tools and resources, such as the SoNaR Semantic Role Labeler (SSRL) and the Predicate Matrix, can be exploited for FrameNet based SRL in Dutch. In this talk I will present this method while discussing some of its difficulties and possible solutions to solve them.

Named Entity Disambiguation with two-stage coherence optimization (Filip Ilievski)
Contemporary Natural Language Processing modules solve Entity Linking, Event Detection, and Semantic Role Labeling as separate problems. From the semantic point of view, each of these processes adds another brush-stroke onto the canvas of meaning: entities and events are components that occur in relations which correspond to roles. The approach presented here extends such NLP processes with a semantic process of coherence optimization. I use both binary logic and probabilistic models built through manual and automatic techniques. The binary filtering phase relies on restrictions from VerbNet and a domain-specific ontology. The optimization phase aims to maximize the coherence between the remaining candidates in a probabilistic manner based on available background knowledge about the entities.

Kind regards,
Filip Ilievski & Chantal van Son

Summer School Perspectives on Subjectivity: July 06-17, 2015

Piek Vossen and his team organize a Summer School course “Perspectives on Subjectivity”, VU University Amsterdam, the Netherlands from July 06-17, 2015.

Amsterdam_Summer_School
Who should join this course?

Advanced Bachelor/ Master students of Linguistics (theoretical, applied or computational), Artificial Intelligence and Journalism, and others interested in cultural perspectives in communication.

Course content

Welcome to Perpectives on Subjectivity: an excellent course in Amsterdam! That is a very subjective opening, as you will agree. Here the subjective perspective of the writer is obvious, but as a rule it is much more subtle. Subjectivity is one of the key elements of natural language. Every communicative act is subjective to some degree. Subjectivity starts with the intentions of the producer of the message and affects its associated functions and syntactic structures, not to mention the choice of vocabulary and associated connotations. All of this can be summarized as perspective.

This course combines theoretical linguistic notions about perspectives with hands-on work on real language data in the lab. Moving between theory, discussions, practical data annotation and data use (machine learning and quantative/ qualitative analysis), you explore a wide range of linguistic phenomena: reference, modality, attribution, registers, sentiment analysis, opinions, temporal processing and so on.

Perspectives on Subjectivity is provided by the Computational Lexicology & Terminology Lab (CLTL), which models computer understanding of natural language with a central role for sources like lexicons, ontologies and terminology. The CLTL is part of the Department of Language and Communication in the Faculty of humanities at VU University Amsterdam.

Learning objectives

  • You are familiar with linguistic theory on major topics in subjectivity and perspective: reference, modality, attribution, registers, sentiment analysis, opinions and temporal processing.
  • You can evaluate the relevant linguistic theory in critical discussions.
  • You can apply the theory tot the description and analysis of real language data.
  • You can annotate that data and analyse it in lab sessions, using machine learning and quantitative techniques (as used in data journalism, for instance).
  • Round table on ‘Time and Language’: Oct. 30, 2014

    Event date:
    Thursday, 30 October, 2014 – 18:30 to 20:00

    The round table “Time and Language”, organized by Tommaso Caselli (VUA, Amsterdam) and Rachele Sprugnoli (DH-FBK), will be held in Genoa on Thursday October 30 as part of “Festival della Scienza “.

    Time is a pervasive element of human life that is also reflected in the language. But how time is encoded in the various languages ​​of the world? How long is an event? What happens if we want to teach a computer to reconstruct the temporal order of events in a text? The philosopher of language Andrea Bonomi, the linguist Pier Marco Bertinetto and the computational linguist Bernardo Magnini will answer these questions to reveal to the public the role that time has in the language and the challenges of technology in this field. Philosophy, linguistics and technology come together and introduce the public to the fascinating relationship between time and language.

    Can machines understand language? According to John Searle, this is fundamentally impossible. He used the Chinese Room thought-experiment to demonstrate that computers follow instructions to manipulate symbols without understanding of these symbols. William van Orman Quine even questioned the understanding of language by humans, since symbols are only grounded through approximation by cultural situational convention. Between these extreme points of views, we are nevertheless communicating every day as part of our social behavior (within Heidegger’s hermeneutic circle), while more and more computers and even robots take part in communication and social interactions.

    The goal of the Spinoza project “Understanding of language by machines” (ULM) is to scratch the surface of this dilemma by developing computer models that can assign deeper meaning to language that approximates human understanding and to use these models to automatically read and understand text. We are building a Reference Machine: a machine that can map natural language to the extra- linguistic world as we perceive it and represent it in our brain.

    This is the first in a series of workshops that we will organize in the Spinoza project to discuss and work on these issues. It marks the kick-off of 4 projects that started in 2014, each studying different aspects of understanding and modeling this through novel computer programs. Every 6-months, we will organize a workshop or event that will bring together different research lines to this central theme and on a shared data sets.

    We investigate ambiguity, variation and vagueness of language; the relation between language, perception and the brain; the role of the world view of the writer of a text and the role of the world view and background knowledge of the reader of a text.
