  7. 5. Identifying Base Noun Phrases by Means of Recurrent Neural Networks : Using Morphological and Dependency Features

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

    Författare :Tonghe Wang; [2020]
    Nyckelord :;

    Sammanfattning : Noun phrases convey key information in communication and are of interest in NLP tasks. A base NP is defined as the headword and left-hand side modifiers of a noun phrase. In this thesis, we identify base NPs in Universal Dependencies treebanks in English and French using an RNN architecture. LÄS MER
