1. Multilingual Abstractions: Abstract Syntax Trees and Universal Dependencies
Abstract : This thesis studies the connections between parsing friendly representations and interlingua grammars developed for multilingual language generation. Parsing friendly representations refer to dependency tree representations that can be used for robust, accurate and scalable analysis of natural language text. READ MORE

2. Multilingual Grammars and Universal Dependencies
Abstract : Abstract syntax trees are an alternative representation to syntactic structures commonly found in NLP systems. This representation allows for sharing of structures across languages, making it well suited to serve as a translation interlingua. READ MORE

3. Best Trees Extraction and Contextual Grammars for Language Processing
Abstract : In natural language processing, the syntax of a sentence refers to the words used in the sentence, their grammatical role, and their order. Semantics concerns the concepts represented by the words in the sentence and their relations, i.e., the meaning of the sentence. READ MORE

4. Complexity and expressiveness for formal structures in Natural Language Processing
Abstract : The formalized and algorithmic study of human language within the field of Natural Language Processing (NLP) has motivated much theoretical work in the related field of formal languages, in particular the subfields of grammar and automata theory. Motivated and informed by NLP, the papers in this thesis explore the connections between expressibility – that is, the ability for a formal system to define complex sets of objects – and algorithmic complexity – that is, the varying amount of effort required to analyse and utilise such systems.

5. Object-Oriented Declarative Program Analysis
Abstract : This thesis deals with techniques for raising the programming level for a particular kind of computations, namely those on abstract syntax trees. Such computations are central in many program analysis tools, such as compilers, smart language-sensitive editors, and static analysis tools. READ MORE
