Representation Learning for Words and Entities Open
This thesis presents new methods for unsupervised learning of distributed representations of words and entities from text and knowledge bases. The first algorithm presented in the thesis is a multi-view algorithm for learning representatio…

Improving Long Distance Slot Carryover in Spoken Dialogue Systems Open
Tracking the state of the conversation is a central component in task-oriented spoken dialogue systems. One such approach for tracking the dialogue state is slot carryover, where a model makes a binary decision if a slot from the context i…

A dataset for resolving referring expressions in spoken dialogue via contextual query rewrites (CQR) Open
We present Contextual Query Rewrite (CQR) a dataset for multi-domain task-oriented spoken dialogue systems that is an extension of the Stanford dialog corpus (Eric et al., 2017a). While previous approaches have addressed the issue of diver…

Scaling Multi-Domain Dialogue State Tracking via Query Reformulation Open
We present a novel approach to dialogue state tracking and referring expression resolution tasks. Successful contextual understanding of multi-turn spoken dialogues requires resolving referring expressions across turns and tracking the ent…

A Critical Examination of RESCAL for Completion of Knowledge Bases with Transitive Relations Open
Link prediction in large knowledge graphs has received a lot of attention recently because of its importance for inferring missing relations and for completing and improving noisily extracted knowledge graphs. Over the years a number of ma…

Problems With Evaluation of Word Embeddings Using Word Similarity Tasks Open
Lacking standardized extrinsic evaluation methods for vector representations of words, the NLP community has relied heavily on word similarity tasks as a proxy for intrinsic evaluation of word vectors. Word similarity evaluation, which cor…

Proceedings of the 1st Workshop on Evaluating Vector-Space Representations for NLP Open
The quality of word representations is frequently assessed using correlation with human judgements of word similarity.Here, we question whether such intrinsic evaluation can predict the merits of the representations for downstream tasks.We…

Weighting Finite-State Transductions With Neural Context Open
How should one apply deep learning to tasks such as morphological reinflection, which stochastically edit one string to get another? A recent approach to such sequence-to-sequence tasks is to compress the input string into a vector that is…

Sublinear Partition Estimation Open
The output scores of a neural network classifier are converted to probabilities via normalizing over the scores of all competing categories. Computing this partition function, $Z$, is then linear in the number of categories, which is probl…
