1. 1. Nested Noun Phrase Detection in English Text with BERT

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Shweta Misra; [2023]
   Nyckelord :Phrase detection; nested noun phrase identification; phrase structure identification; sentence parsing; transformer models; machine learning; natural language processing; Frasdetektering; kapslad substantivfrasidentifiering; frasstrukturidentifiering; meningsanalys; transformers-modeller; maskininlärning; naturlig språkbehandling;

   Sammanfattning : In this project, we address the task of nested noun phrase identification in English sentences, where a phrase is defined as a group of words functioning as one unit in a sentence. Prior research has extensively explored the identification of various phrases for language understanding and text generation tasks. LÄS MER

3. 2. A Survey of Non-Projective Dependencies and a Novel Approach to Projectivization for Parsing

   Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologi

   Författare :James Decatur; [2022]
   Nyckelord :dependency parsing; non-projective dependencies; projectivization;

   Sammanfattning : Non-projective dependencies remain an at large issue in the field of dependency parsing. Regardless of what parsing algorithm is used, researchers run into the issue of computational speed and lower parsing performance on non-projective dependencies than on projective dependencies.

4. 3. Multilingual Zero-Shot and Few-Shot Causality Detection

   Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologi

   Författare :Sebastian Michael Reimann; [2021]
   Nyckelord :classification; causality; causal relation; multilingual; cross-lingual; zero-shot; few-shot; bert; xlm-r; laser;

   Sammanfattning : Relations that hold between causes and their effects are fundamental for a wide range of different sectors. Automatically finding sentences that express such relations may for example be of great interest for the economy or political institutions. LÄS MER

5. 4. Attention Mechanisms for Transition-based Dependency Parsing

   Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologi

   Författare :Johannes Gontrum; [2019]
   Nyckelord :natural language processing; language technology; dependency parsing; transition-based parsing; parsing; attention;

   Sammanfattning : Transition-based dependency parsing is known to compute the syntactic structure of a sentence efficiently, but is less accurate to predict long-distance relations between tokens as it lacks global information about the sentence. Our main contribution is the integration of attention mechanisms to replace the static token selection with a dynamic approach that takes the complete sequence into account. LÄS MER

7. 5. Using Unsupervised Morphological Segmentation to Improve Dependency Parsing for Morphologically Rich Languages

   Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologi

   Författare :Zulipiye Yusupujiang; [2018]
   Nyckelord :;

   Sammanfattning : In this thesis, we mainly investigate the influence of using unsupervised morphological segmentation as features on the dependency parsing of morphologically rich languages such as Finnish, Estonian, Hungarian, Turkish, Uyghur, and Kazakh. Studying the morphology of these languages is of great importance for the dependency parsing of morphologically rich languages since dependency relations in a sentence of these languages mostly rely on morphemes rather than word order.
