 Linguistics Circle occasional seminar series

The Institute of Linguistics organises an occasional series of seminars, where local and international speakers are invited to present the results of recent research which is of interest to both professional (computational) linguists and members of the broader public.
The seminars take place in an informal setting and their primary aim is to encourage discussion. Students and members of the public are welcome to attend!

Current Seminars (2017-2018):
I am always looking for speakers in the Linguistics Circle Seminar. Please contact Lonneke van der Plas if you have something to present.

Title: The lexicon of gaze. Methods of analysis and research results

Date: Friday 27th April at 12:00

Venue: LBR2

 

While in the domain of body communication several authors have written down lexicons of gestures, no similar endeavour has been undertaken about eye-gaze signals.

This work presents  some studies aimed at describing the phonology, the lexicon, and the morphology of the communication system of gaze. I will show how such investigation may exploit various research methods, from ethnosemantics to observational analysis, from empirical studies to computer simulation, and overview the general structure of the lexicon of gaze, finally focusing on some specific lexicons, like one of the orchestra conductor’s gaze.

Title: Exploring discriminatory attitudes in Malta: a discourse-analytic approach 

Date: Friday 23rd March at 12:00

Venue: GW156 


In this talk, we will summarise the research carried out at the Institute of Linguistics and Language Technology of the University of Malta under the auspices of the EU co-funded C.O.N.T.A.C.T. project. Our study, which followed the common methodology of the C.O.N.T.A.C.T. consortium, focused on hate speech as a manifestation of hate crime in Malta. More specifically, through quantitative and qualitative analyses, we sought to identify the extent to which comments posted online in reaction to articles in local news portals can be found to encompass discriminatory attitudes towards two target minorities: migrants and members of the LGBTIQ community. The obtained results indicate that while both xenophobia and homophobia can be detected in some of the comments made by online users in local news portals, the former is a much more prevalent than the latter. In an attempt to further probe into the reasons for the emergence of such discriminatory discourse online, we then administered an online questionnaire and conducted focus group interviews, which provided us with some insights as to why discriminatory attitudes appear to have recently been on the rise in relation to migrants, and seem to have been correspondingly contained in the case of the LGBTIQ minority group.

Title: Transfer Learning for Natural Language Processing (NLP) - Where are we now?

Date: Friday 16th March at 12:00

Venue: GW156

 

Understanding language automatically is at the core of Natural Language Processing (NLP), a fast-growing research  field. Deep learning has brought rapid advances in NLP and improved performance to a point which enables industrial use. However, current NLP models are static and unable to adapt. They can solve only one problem at a time and cannot generalize from closely related problems: every time a new language, task or domain is encountered a new system is developed from scratch.  In this talk I will survey recent transfer learning approaches for NLP. These include work on deep multi-task learning, semi-supervised and cross-lingual learning for leveraging limited (or fortuitous) annotated resources.

Title: "Emotion Analysis in Social Media: Corpus Annotation and
Predictive Models"

Date: Friday 9th March at 12:00


Venue: GW156


"Emotion analysis in text is an extension to sentiment analysis in the
sense that classes to be predicted are not only positive and negative,
but (for instance) joy, anger, fear, surprise, disgust, and sadness. In
the first part of this talk, I will report on a corpus annotation study
on Twitter and results of state-of-the-art models known from sentiment
analysis. In the second part, I will highlight some remaining
challenges, including multimodal information (images and text) and the
meaning of modifiers (which emotion is "I am not angry"?).

Title: Collecting an Annotated Image Description Corpus for the Generation of Rich Face Descriptions

Date: Wednesday 28th February at 12:00 

Venue: LC118

The past few years have witnessed renewed interest in NLP tasks at the
interface between vision and language. One intensively-studied problem
is that of automatically generating text from images. In this paper,
we extend this problem to the more specific domain of face
description. Unlike scene descriptions, face descriptions are more
fine-grained and rely on attributes extracted from the image, rather
than objects and relations. Given that no data exists for this task,
we present an ongoing crowd sourcing study to collect a corpus of
descriptions of face images taken `in the wild'. To gain a better
understanding of the variation we find in face description and the
possible issues that this may raise, we also conducted an annotation
study on a subset of the corpus. Primarily, we found descriptions to
refer to a mixture of attributes, not only physical, but also
emotional and inferential, which is bound to create further challenges
for current image-to-text methods.
