Ultra-Narrowband Optimization

VideoLectures.NET

This paper proposes the first experimental architecture designed for the optimization of UNB networks. The proposed architecture enables context data collection, context model development, optimization and transmission control using rapid experimentation cycle approach enabled by flow based programming using Node-RED. Through preliminary results, we show the feasibility of PHY and MAC context data collection, point out challenges that are specific for UNB context modeling and discuss options for optimization. All datasets, context modeling and optimization tools used in the paper will be released as open source.


Defence of the Doctoral Dissertation: Machine Learning of Semantics for Text Understanding

VideoLectures.NET

We propose two rule-based approaches for mapping text into predicate logic. This led us to develop a grammar induction approach for semantic parsing and ontology learning. The induced context-free grammar parses a sentence of text into a semantic tree, which is a meaning representation, where each node has its own semantic category, e.g. To evaluate the models, we propose a new metric -- the accuracy of the classifier trained on the generated dataset and tested on the original, manually constructed dataset.


Creation of Standards for Social Media Corpora: a Digital Humanities Topic Par Excellence

VideoLectures.NET

Even though empirical research of computer-mediated communication (CMC) has a tradition of almost two decades, there are still only very few annotated CMC/social media corpora which are available to the scientific community and the public. One crucial issue is the unclear legal situation w.r.t. On the example of a legal expertise sought for the integration of an existing German chat corpus into CLARIN-D, the talk will highlight this issue (according to German law) and describe how it has been handled in the project. The creation of standards and the adaptation of NLP tools for that new type of language resource is a digital humanities topic par excellence since (1) it focuses on data which are born digital while at the same time (2) it requires a combination of expertise from humanities and computational sciences.


Text Analysis for Social Media Cybersecurity: the AMiCA Project

VideoLectures.NET

The text analysis part of the AMiCA project (http://www.amicaproject.be), a cooperation between the University of Antwerp and the University of Ghent, developed methods and software to help moderators detect occurrences of unwanted or dangerous situations in their social networks. More specifically, the project developed prototype systems for the detection of cyberbullying, suicide announcements, and sexually transgressive behavior. In this talk I will focus on the text analysis methods that were used for normalization of social media text, for profiling users, and for detecting dangerous content. I will describe the architectures and results of the three resulting applications.


CLARIN-PLUS workshop "Creation and Use of Social Media Resources", Kaunas 2017

VideoLectures.NET

With the increasing volume and impact of communication on social media, social media analysis has become one of the most trending topics in natural language research, which can be observed in a growing number of workshops and conferences dedicated to this topic, projects funded, and research centers established. As a result, a number of social media resources containing chats, online commentaries, reviews, blogs, emails, forums, etc., as well as audio and video recordings, have been accumulated in the repositories of CLARIN centers. What is more, due to their distinct communicative characteristics, they pose new technical challenges for the standard natural language processing tools as well as new legal and ethical challenges for the dissemination of such resources, which has also been addressed by CLARIN, making the available infrastructure an important means for attracting new users to the CLARIN community.

The aims of the CLARIN-PLUS workshop "Creation and Use of Social Media Resources" are: to demonstrate the possibilities of social media resources and natural language processing tools for researchers with a diverse research background who are interested in empirical research of language and social practices in computer-mediated communication; to promote interdisciplinary cooperation possibilities; to initiate a discussion on the various approaches to social media data collection and processing.


CLARIN - Common Language Resources and Technology Infrastructure

VideoLectures.NET

CLARIN makes digital language resources available to scholars, researchers, students and citizen-scientists from all disciplines, especially in the humanities and social sciences, through single sign-on access. CLARIN offers long-term solutions and technology services for deploying, connecting, analyzing and sustaining digital language data and tools. CLARIN supports scholars who want to engage in cutting edge data-driven research, contributing to a truly multilingual European Research Area.
