1. 1. Unsupervised multilingual distractor generation for fill-in-the-blank questions

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

   Författare :Zhe Han; [2022]
   Nyckelord :Multilingual; Distractor; BERT;

   Sammanfattning : Fill-in-the-blank multiple choice questions (MCQs) play an important role in the educational field, but the manual generation of them is quite resource-consuming, so it has gradually turned into an attractive NLP task. Thereinto, question creation itself has become a mainstream NLP research topic, while distractor (wrong alternative) generation (DG) still remains out of the spotlight. LÄS MER

3. 2. Using WordNet Synonyms and Hypernyms in Automatic Topic Detection

   Kandidat-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

   Författare :Nicko Wargärde; [2020]
   Nyckelord :topic detection; TF-IDF; SynPlusTF-IDF; keyword extraction; WordNet; synsets; synonyms; hypernyms;

   Sammanfattning : Detecting topics by extracting keywords from written text using TF-IDF has been studied and successfully used in many applications. Adding a semantic layer to TF-IDF-based topic detection using WordNet synonyms and hypernyms has been explored in document clustering by assigning concepts that describe texts or by adding all synonyms and hypernyms that occurring words have to a list of keywords.

4. 3. Authorship classification using the Vector Space Model and kernel methods

   Master-uppsats, Uppsala universitet/Statistiska institutionen

   Författare :Emil Westin; [2020]
   Nyckelord :vector space model; semantic kernel; support vector machine; bag-of-words;

   Sammanfattning : Authorship identification is the field of classifying a given text by its author based on the assumption that authors exhibit unique writing styles. This thesis investigates the semantic shortcomings of the vector space model by constructing a semantic kernel created from WordNet which is evaluated on the problem of authorship attribution.

5. 4. Asset Finder: A Search Tool forFinding Relevant Graphical AssetsUsing Automated Image Labelling

   Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Max Perea Düring; Anton Gildebrand; Markus Linghede; [2019]
   Nyckelord :;

   Sammanfattning : The creation of digital 3D-environments appears in a variety of contexts such as movie making, video game development, advertising, architecture, infrastructure planning and education. When creating these environments it is sometimes necessary to search for graphical assets in big digital libraries by trying different search terms. LÄS MER

7. 5. Domain Adaptation for Hypernym Discovery via Automatic Collection of Domain-Specific Training Data

   Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

   Författare :Johannes Palm Myllylä; [2019]
   Nyckelord :NLP; natural language processing; domain adaptation; hypernym; hyponym;

   Sammanfattning : Identifying semantic relations in natural language text is an important component of many knowledge extraction systems. This thesis studies the task of hypernym discovery, i.e discovering terms that are related by the hypernymy (is-a) relation. LÄS MER
