A Proof-Theoretic Approach to Scope Ambiguity in Compositional Vector Space Models
We investigate the extent to which compositional vector space models can be
used to account for scope ambiguity in quantified sentences (of the form "Every
man loves some woman"). Such sentences containing two quantifiers introduce two
readings, a direct scope reading and an inverse scope reading. This ambiguity
has been treated in a vector space model using bialgebras by (Hedges and
Sadrzadeh, 2016) and (Sadrzadeh, 2016), though without an explanation of the
mechanism by which the ambiguity arises. We combine a polarised focussed
sequent calculus for the non-associative Lambek calculus NL, as described in
(Moortgat and Moot, 2011), with the vector based approach to quantifier scope
ambiguity. In particular, we establish a procedure for obtaining a vector space
model for quantifier scope ambiguity in a derivational way.Comment: This is a preprint of a paper to appear in: Journal of Language

Short versions presented in DSALT 2016, SaLMoM 2016, LACL 2016. A version presented in AC 2017Vector models of language are based on the contextual aspects of language, the distributions of words and how they co-occur in text. Truth conditional models focus on the logical aspects of language, compositional properties of words and how they compose to form sentences. In the truth conditional approach, the denotation of a sentence determines its truth conditions, which can be taken to be a truth value, a set of possible worlds, a context change potential, or similar. In the vector models, the degree of co-occurrence of words in context determines how similar the meanings of words are. In this paper, we put these two models together and develop a vector semantics for language based on the simply typed lambda calculus models of natural language. We provide two types of vector semantics: a static one that uses techniques familiar from the truth conditional tradition and a dynamic one based on a form of dynamic interpretation inspired by Heim's context change potentials. We show how the dynamic model can be applied to entailment between a corpus and a sentence and we provide examples
A Comparison of Feature-Based and Neural Scansion of Poetry
Automatic analysis of poetic rhythm is a challenging task that involves
linguistics, literature, and computer science. When the language to be analyzed
is known, rule-based systems or data-driven methods can be used. In this paper,
we analyze poetic rhythm in English and Spanish. We show that the
representations of data learned from character-based neural models are more
informative than the ones from hand-crafted features, and that a
Bi-LSTM+CRF-model produces state-of-the art accuracy on scansion of poetry in
two languages. Results also show that the information about whole word
structure, and not just independent syllables, is highly informative for
performing scansion.Comment: RANLP 201
Unsupervised, Knowledge-Free, and Interpretable Word Sense Disambiguation
Interpretability of a predictive model is a powerful feature that gains the
trust of users in the correctness of the predictions. In word sense
disambiguation (WSD), knowledge-based systems tend to be much more
interpretable than knowledge-free counterparts as they rely on the wealth of
manually-encoded elements representing word senses, such as hypernyms, usage
examples, and images. We present a WSD system that bridges the gap between
these two so far disconnected groups of methods. Namely, our system, providing
access to several state-of-the-art WSD models, aims to be interpretable as a
knowledge-based system while it remains completely unsupervised and
knowledge-free. The presented tool features a Web interface for all-word
disambiguation of texts that makes the sense predictions human readable by
providing interpretable word sense inventories, sense representations, and
disambiguation results. We provide a public API, enabling seamless integration.Comment: In Proceedings of the the Conference on Empirical Methods on Natural

THE KNOWLEDGE OF PROSODY IN HELPING STUDENTS RESPONSE UTTERANCES APPROPRIATELY
In spoken discourse, besides the use of vocal and gestural signs, prosody is an
important part to consider since without appropriate prosody- Intonation and accent
and the meaningful elements of speech apart from the words that are uttered (Kreidler,
1998), the speaker may fail to deliver the meanings and the listeners may fail to catch
the message. Then, it results in misunderstanding. This study is conducted to find out
whether the knowledge of prosody helps students to communicate appropriately. The
participants of this study are 20 students who joined semantics and 20 students who did
not take semantics. They were asked to give appropriate respond to contrast the 20
utterance which have emphases. The utterances are recorded and transcribed.
Triangulation was done by another person to get the accuracy of the data. The result
shows that there are more students (85% ) who have knowledge of prosody able to
respond the utterances appropriately. This proves that teaching prosody is essensial to
make the students realize the function of prosody
