Emotional Facial Expressions In Synthesised Sign Language Avatars: A Manual Evaluation., Robert G Smith, Brian Nolan
Emotional Facial Expressions In Synthesised Sign Language Avatars: A Manual Evaluation., Robert G Smith, Brian Nolan
Other Resources
This research explores and evaluates the contribution that facial expressions might have regarding improved comprehension and acceptability in sign language avatars. Focusing specifically on Irish sign language (ISL), the Deaf (the uppercase ‘‘D’’ in the word ‘‘Deaf’’ indicates Deaf as a culture as opposed to ‘‘deaf’’ as a medical condition) community’s responsiveness to sign language avatars is examined. The hypothesis of this is as follows: augmenting an existing avatar with the seven widely accepted universal emotions identified by Ekman (Basic emotions: handbook of cognition and emotion. Wiley, London, 2005) to achieve underlying facial expressions will make that avatar more human-like …
A Computational Translation Of The Phaistos Disk, Peter Revesz
A Computational Translation Of The Phaistos Disk, Peter Revesz
School of Computing: Conference and Workshop Papers
For over a century the text of the Phaistos Disk remained an enigma without a convincing translation. This paper presents a novel semi-automatic translation method that uses for the first time a recently discovered connection between the Phaistos Disk symbols and other ancient scripts, including the Old Hungarian alphabet. The connection between the Phaistos Disk script and the Old Hungarian alphabet suggested the possibility that the Phaistos Disk language may be related to Proto-Finno-Ugric, Proto-Ugric, or Proto-Hungarian. Using words and suffixes from those languages, it is possible to translate the Phaistos Disk text as an ancient sun hymn, possibly connected …
A Computational Study Of The Evolution Of Cretan And Related Scripts, Peter Revesz
A Computational Study Of The Evolution Of Cretan And Related Scripts, Peter Revesz
School of Computing: Conference and Workshop Papers
Crete was the birthplace of several ancient writings, including the Cretan Hieroglyphs, the Linear A and the Linear B scripts. Out of these three only Linear B is deciphered. The sound values of the Cretan Hieroglyph and the Linear A symbols are unknown and attempts to reconstruct them based on Linear B have not been fruitful. In this paper, we compare the ancient Cretan scripts with four other Mediterranean and Black Sea scripts, namely Phoenician, South Arabic, Greek and Old Hungarian. We provide a computational study of the evolution of the three Cretan and four other scripts. This study encompasses …
Providing Objective Metrics Of Team Communication Skills Via Interpersonal Coordination Mechanisms, Celine De Looze, Brian Vaughan, Finnian Kelly, Alison Kay
Providing Objective Metrics Of Team Communication Skills Via Interpersonal Coordination Mechanisms, Celine De Looze, Brian Vaughan, Finnian Kelly, Alison Kay
Conference Papers
Being able to communicate efficiently has been acknowledged as a vital skill in many different domains. In particular, team communication skills are of key importance in the operation of complex machinery such as aircrafts, maritime vessels and such other, highly-specialized, civilian or military vehicles, as well as the performance of complex tasks in the medical domain. In this paper, we propose to use prosodic accommodation and turn- taking organisation to provide objective metrics of communica- tion skills. To do this, human-factors evaluations, via a coordi- nation Demand Analysis (CDA), were used in conjunction with a dynamic model of prosodic accommodation …
A Study On The Efficacy Of Sentiment Analysis In Author Attribution, Michael J. Schneider
A Study On The Efficacy Of Sentiment Analysis In Author Attribution, Michael J. Schneider
Electronic Theses and Dissertations
The field of authorship attribution seeks to characterize an author’s writing style well enough to determine whether he or she has written a text of interest. One subfield of authorship attribution, stylometry, seeks to find the necessary literary attributes to quantify an author’s writing style. The research presented here sought to determine the efficacy of sentiment analysis as a new stylometric feature, by comparing its performance in attributing authorship against the performance of traditional stylometric features. Experimentation, with a corpus of sci-fi texts, found sentiment analysis to have a much lower performance in assigning authorship than the traditional stylometric features.

Towards News Verification: Deception Detection Methods For News Discourse, Yimin Chen, Victoria L. Rubin, Niall Conroy

News verification is a process of determining whether a particular news report is truthful or deceptive. Deliberately deceptive (fabricated) news creates false conclusions in the readers’ minds. Truthful (authentic) news matches the writer’s knowledge. How do you tell the difference between the two in an automated way? To investigate this question, we analyzed rhetorical structures, discourse constituent parts and their coherence relations in deceptive and truthful news sample from NPR’s “Bluff the Listener”. Subsequently, we applied a vector space model to cluster the news by discourse feature similarity, achieving 63% accuracy. Our predictive model is not significantly better than chance …
Classifying Idiomatic And Literal Expressions Using Vector Space Representations, Jing Peng, Anna Feldman, Hamza Jazmati
Classifying Idiomatic And Literal Expressions Using Vector Space Representations, Jing Peng, Anna Feldman, Hamza Jazmati
Department of Computer Science Faculty Scholarship and Creative Works
We describe an algorithm for automatic classification of idiomatic and literal expressions. Our starting point is that idioms and literal expressions occur in different contexts. Idioms tend to violate cohesive ties in local contexts, while literals are expected to fit in. Our goal is to capture this intuition using a vector representation of words. We propose two approaches: (1) Compute inner product of context word vectors with the vector representing a target expression. Since literal vectors predict well local contexts, their inner product with contexts should be larger than idiomatic ones, thereby telling apart literals from idioms; and (2) Compute …
Metadata And Linked Data In Word Sense Disambiguation, Matthew Corsmeier
Metadata And Linked Data In Word Sense Disambiguation, Matthew Corsmeier
Library Philosophy and Practice (e-journal)
Word Sense Disambiguation (WSD) can be assisted by taking advantage of the metadata embedded in the various ontologies, lexica, databases, etc… that exist in the Semantic Web. Automated processes that exploit the links already present in the Semantic Web can strengthen parsing of word senses by using user-contributed and semantically-linked data. These processes are only possible because of a commitment to interoperability and the creation of shared standards. This paper will review some of the most heavily used Linguistic Linked Open Data (LLOD) tools and models which show the most promise for using metadata to alleviate problems caused by polysemous …
