  1. 6. Word Vector Representations using Shallow Neural Networks

    Författare :Oluwatosin Adewumi; Marcus Liwicki; Marco Kuhlmann; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Word vectors; NLP; Neural networks; Embeddings; Maskininlärning; Machine Learning;

    Sammanfattning : This work highlights some important factors for consideration when developing word vector representations and data-driven conversational systems. The neural network methods for creating word embeddings have gained more prominence than their older, count-based counterparts. LÄS MER

  3. 7. Sentiment and Stance Visualization of Textual Data for Social Media

    Författare :Kostiantyn Kucher; Andreas Kerren; Carita Paradis; Magnus Sahlgren; Ross Maciejewski; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; stance visualization; sentiment visualization; text visualization; stance analysis; sentiment analysis; opinion mining; visualization; interaction; visual analytics; NLP; text mining; text analytics; social media; Informations- och programvisualisering; Information and software visualization;

    Sammanfattning : Rapid progress in digital technologies has transformed the world in many ways during the past few decades, in particular, with the new means of communication such as social media. Social media platforms typically rely on textual data produced or shared by the users in multiple timestamped posts. LÄS MER

  4. 8. Bootstrapping Named Entity Annotation by Means of Active Machine Learning: A Method for Creating Corpora

    Författare :Fredrik Olsson; RISE; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; corpus creation; data annotation; active learning; named entity recognition; machine learning; computational linguistics; nlp;

    Sammanfattning : This thesis describes the development and in-depth empirical investigation of a method, called BootMark, for bootstrapping the marking up of named entities in textual documents. The reason for working with documents, as opposed to for instance sentences or phrases, is that the BootMark method is concerned with the creation of corpora. LÄS MER

  5. 9. Linguistically Informed Neural Dependency Parsing for Typologically Diverse Languages

    Författare :Miryam de Lhoneux; Joakim Nivre; Sara Stymne; Emily Bender; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Dependency parsing; multilingual NLP; Universal Dependencies; Linguistically informed NLP; Computational Linguistics; Datorlingvistik;

    Sammanfattning : This thesis presents several studies in neural dependency parsing for typologically diverse languages, using treebanks from Universal Dependencies (UD). The focus is on informing models with linguistic knowledge. LÄS MER

  7. 10. Contributions to Shallow Discourse Parsing : To English and beyond

    Författare :Murathan Kurfalı; Robert Östling; Mats Wirén; Christian Hardmeier; Amir Zeldes; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; discourse; discourse relations; shallow discourse parsing; transfer learning; multilinguality; low-resource nlp; Linguistics; lingvistik;

    Sammanfattning : Discourse is a coherent set of sentences where the sequential reading of the sentences yields a sense of accumulation and readers can easily follow why one sentence follows another. A text that lacks coherence will most certainly fail to communicate its intended message and leave the reader puzzled as to why the sentences are presented together. LÄS MER
