• Abstract: We analyze two Natural Language Inference data sets with respect to their linguistic features. The goal is to identify those syntactic and semantic properties that are particularly hard to comprehend for a machine learning model. To this end, we also investigate the differences between a crowd-sourced, machine-translated data set (SNLI) and a collection of text pairs from internet sources. Our main findings are, that the model has difficulty recognizing the semantic importance of prepositions and verbs, emphasizing the importance of linguistically aware pre-training tasks. Furthermore, it often does not comprehend antonyms and homonyms, especially if those are depending on the context. Incomplete sentences are another problem, as well as longer paragraphs and rare words or phrases. The study shows that automated language understanding requires a more informed approach, utilizing as much external knowledge as possible throughout the training process.

  We take the approach of developing curated synthetic data on a large scale, with specific properties. We use a new multiple-choice task and datasets, Blackbird Language Matrices, to focus on a specific grammatical structural phenomenon. We show that despite having been trained on multilingual texts in a consistent manner, multilingual pretrained language models have language-specific differences.

  Semantic and syntactic bootstrapping posit that children use their prior knowledge of one linguistic domain, say syntactic relations, to help later acquire another, such as the meanings of new words. Here, we argue that they are instead both contingent on a more general learning strategy for language acquisition: joint learning. Using a series of neural visually-grounded grammar induction models, we demonstrate that both syntactic and semantic bootstrapping effects are strongest when syntax and semantics are learnt simultaneously.

  We analyze tasks covering syntax, semantics and reasoning, across 2M pre-training steps and five seeds. We identify critical learning phases across tasks and time, during which subspaces emerge, share information, and later disentangle to specialize. Our findings have implications for model interpretability, multi-task learning, and learning from limited data.

  Infusing language models with syntactic or semantic knowledge from structural linguistic priors has shown improvements on many language understanding tasks. We conduct empirical study of replacing parsed graphs or trees with trivial ones for tasks in the GLUE benchmark. It reveals that the gains might not be significantly attributed to explicit linguistic priors but rather to more feature interactions brought by fusion layers.

• Transparency Helps Reveal When Language Models Learn Meaning [71.96920839263457]
  Our systematic experiments with synthetic data reveal that, with languages where all expressions have context-independent denotations, both autoregressive and masked language models learn to emulate semantic relations between expressions. Turning to natural language, our experiments with a specific phenomenon -- referential opacity -- add to the growing body of evidence that current language models do not well-represent natural language semantics.

  We focus on the internals of an NLI classifier trained by an emphexplainable machine learning algorithm. We use this perspective in order to tackle both NLI and a companion task, guessing whether a text has been written by a native or a non-native speaker. We investigate which kind of linguistic traits are most effective for solving our two tasks, namely, are most indicative of a speaker's L1.

  This thesis focuses on understanding certain potentials of contexts in neural models and design augmentation models to benefit from them. To translate from a source language to a target language, a neural model has to understand the meaning of constituents in the provided context. Looking more in-depth into the role of context and the impact of data on learning models is essential to advance the NLP field.

  We use singular vector canonical correlation analysis to study what kind of information is induced from each source. We observe that our representations embed typology and strengthen correlations with language relationships. We then take advantage of our multi-view language vector space for multilingual machine translation, where we achieve competitive overall translation accuracy.
