Dasher - A data entry interface using continuous gestures and language models

Existing devices for communicating information to computers are bulky, slow to use, or unreliable. Dasher is a new interface incorporating language modelling and driven by continuous two-dimensional gestures, e.g. a mouse, touchscreen, or eye-tracker. Tests have shown that this device can be used to enter text at a rate of up to 34 words per minute, compared with typical ten-finger keyboard typing of 40-60 words per minute. Although the interface is slower than a conventional keyboard, it is small and simple, and could be used on personal data assistants and by motion-impaired computer users.

Statistical parametric speech synthesis based on speaker and language factorization

An increasingly common scenario in building speech synthesis and recognition systems is training on inhomogeneous data. This paper proposes a new framework for estimating hidden Markov models on data containing both multiple speakers and multiple languages. The proposed framework, speaker and language factorization, attempts to factorize speaker-/language-specific characteristics in the data and then model them using separate transforms. Language-specific factors in the data are represented by transforms based on cluster mean interpolation with cluster-dependent decision trees. Acoustic variations caused by speaker characteristics are handled by transforms based on constrained maximum-likelihood linear regression. Experimental results on statistical parametric speech synthesis show that the proposed framework enables data from multiple speakers in different languages to be used to: train a synthesis system; synthesize speech in a language using speaker characteristics estimated in a different language; and adapt to a new language. © 2012 IEEE.

Leveraging Learning and Language Via Communication Bootstrapping

In a Communication Bootstrapping system, peer components with different perceptual worlds invent symbols and syntax based on correlations between their percepts. I propose that Communication Bootstrapping can also be used to acquire functional definitions of words and causal reasoning knowledge. I illustrate this point with several examples, then sketch the architecture of a system in progress which attempts to execute this task.

Naive Physics, Event Perception, Lexical Semantics, and Language Acquisition

This thesis proposes a computational model of how children may come to learn the meanings of words in their native language. The proposed model is divided into two separate components. One component produces semantic descriptions of visually observed events while the other correlates those descriptions with co-occurring descriptions of those events in natural language. The first part of this thesis describes three implementations of the correlation process whereby representations of the meanings of whole utterances can be decomposed into fragments assigned as representations of the meanings of individual words. The second part of this thesis describes an implemented computer program that recognizes the occurrence of simple spatial motion events in simulated video input.

Improving bilingual higher education: Training university professors in content and language integrated learning

With increasing international mobility, higher education must cater to the varying linguistic and cultural needs of students. Successful delivery of courses through English as the vehicular language is essential to encourage international enrollment. However, this cannot be achieved without preparing university professors in the many intricacies delivering their subjects in English may pose. This paper aims to: share preliminary data concerning Content and Language Integrated Learning (CLIL) at Laureate Network Universities worldwide as few studies have been conducted at the tertiary level, reflect upon data regarding student and teacher satisfaction with CLIL at the Universidad Europea de Madrid (UEM), and to propose improvements in English-taught subjects.

Monstrative acts and becoming-monster: on identity, bodies, and the feminine other

Using two examples of literary monsters, the Creature in Mary Shelley’s Frankenstein (1818), and Grendel’s Mother in Beowulf, this thesis demonstrates the bearing fictional identities have on “real” bodies, through an examination of two further literary texts, David Henry Hwang’s play, M. Butterfly (1986) and J. M. Coetzee’s novel, Disgrace (1999). Western definitions of Being have historically divided body and mind, favouring the mind as formative of subjective experience and denigrating the body as secondary and impure. This thesis demonstrates that this mind/body binary is symptomatic of the masculine ontological imperative to disown the body and its effects on Being, simultaneously ridding itself of the feminine it believes is its irrational opposite. Using recent feminist reviews of the canon, which emphasise the body’s importance to ontology and demonstrate the conceptual association between the feminine and the corporeal, this thesis links performative identity practices to theories of monstrosity, explaining how fictional qualities adhere to monstrous bodies by proposing a new theoretical category, the “monstrative.” The monstrative is a performative force that makes the Other into a living sign of Otherness; however, unlike earlier theories of Othering, the monstrative accounts for the Other’s being other to herself. This thesis also attempts to read the misrepresented body of the Other as a possible site for more empowered identity performances, where the monstrous “I” is interpreted as a potentially positive model for identity practice, through the conceptualisation of identity as a process of Becoming rather than Being. The transferal from a noun to a verb not only emphasises the performativity of identity, but also suggests fluidity and multiplicity in identity practice, which always already indicates a monstrosity at work. Thus, while monstrative acts constitute bodies as monstrous, Becoming-monster is an empathetic response to the Other’s monstrosity.

H.M.'s personal crossword puzzles: understanding memory and language.

The amnesic patient H.M. has been solving crossword puzzles nearly all his life. Here, we analysed the linguistic content of 277 of H.M.'s crossword-puzzle solutions. H.M. did not have any unusual difficulties with the orthographic and grammatical components inherent to the puzzles. He exhibited few spelling errors, responded with appropriate parts of speech, and provided answers that were, at times, more convincing to observers than those supplied by the answer keys. These results suggest that H.M.'s lexical word-retrieval skills remain fluid despite his profound anterograde amnesia. Once acquired, the maintenance of written language comprehension and production does not seem to require intact medial temporal lobe structures.
