11. Discourse in Statistical Machine Translation
Sammanfattning : This thesis addresses the technical and linguistic aspects of discourse-level processing in phrase-based statistical machine translation (SMT). Connected texts can have complex text-level linguistic dependencies across sentences that must be preserved in translation. However, the models and algorithms of SMT are pervaded by locality assumptions. LÄS MER
12. Cross-language Ontology Learning : Incorporating and Exploiting Cross-language Data in the Ontology Learning Process
Sammanfattning : An ontology is a knowledge-representation structure, where words, terms or concepts are defined by their mutual hierarchical relations. Ontologies are becoming ever more prevalent in the world of natural language processing, where we currently see a tendency towards using semantics for solving a variety of tasks, particularly tasks related to information access.

13. Ask and distract : Data-driven methods for the automatic generation of multiple-choice reading comprehension questions from Swedish texts
Sammanfattning : Multiple choice questions (MCQs) are widely used for summative assessment in many different subjects. The tasks in this format are particularly appealing because they can be graded swiftly and automatically. LÄS MER
14. Incongruous tense in Swedish : Past and present tense use with deviant time reference
Sammanfattning : This thesis deals with incongruous tense in Swedish. Incongruous tense refers to uses of the past tense for events that overlap or succeed the moment of speech, which is normally considered to apply to the present tense, and uses of the present tense for events that precede the moment of speech, which is normally considered to apply to the past tense.

15. The Search for Syntax : Investigating the Syntactic Knowledge of Neural Language Models Through the Lens of Dependency Parsing
Sammanfattning : Syntax — the study of the hierarchical structure of language — has long featured as a prominent research topic in the field of natural language processing (NLP). Traditionally, its role in NLP was confined towards developing parsers: supervised algorithms tasked with predicting the structure of utterances (often for use in downstream applications). LÄS MER
