Knowledge extraction from fictional texts [article]

Cuong Xuan Chu, Universität Des Saarlandes
2022
However, current knowledge extraction methods mostly focus on prominent real world entities with Wikipedia and mainstream news articles as sources.  ...  Unlike the real-world domain, knowledge extraction on such specific domains like fiction and fantasy has to tackle several key challenges: • Training data.  ...  Some of the methods leverage existing knowledge graphs, like YAGO, DBpedia and learn their embeddings to automatically extract the taxonomies [Martel and Zouaq, 2021] .  ...

Analyzing Bias in a Knowledge-Aware News Recommendation System

Hannah Elisabeth Greven
2021
This thesis investigates bias in the KRED NRS, a content-based knowledge-aware NRS that uses a knowledge graph as side information.  ...  In recent years, there has been a surge of research on bias in recommendation systems examining bias in word, text, and knowledge graph embeddings.  ...  Several knowledge graphs have been proposed in the last decade, like Google's Knowledge Graph [50] and Microsoft's Satori [18] but also public knowledge graphs, such as DBpedia [31] , WikiData [54  ...

Representation and contextualization for document understanding [article]

Nam Khanh Tran, University, My, University, My
2019
To obtain a full understanding of the meaning of the document, that prior knowledge, therefore, has to be retrieved to supplement the text in the document.  ...  The second problem is about acquiring document context. A document cannot be fully understood in isolation since it may refer to knowledge that is not explicitly included in its textual content.  ...  [HYB + 11]), which is crucial for robust linking of entity mentions to Wikipedia entity pages or entity representations in other knowledge bases, such as, Yago, DBPedia or Freebase.  ...

Using Wikipedia Knowledge and Query Types in a New Indexing Approach for Web Search Engines

Falah Hassan Ali Al-Akashi, Université D'Ottawa / University Of Ottawa, Université D'Ottawa / University Of Ottawa
2014
Modern search engines struggle to index it independent of the structure of queries and type of Web data, and commonly use indexing based on Web's graph structure to identify high-quality relevant pages  ...  Our aim is to design a powerful search engine with a strong focus on how to make the first page highly relevant to the user, and on how to retrieve other pages based on that first page.  ...  Other resources are providing highly structured representations of Wikipedia, such as DBPedia 5 , Yago 6 and Wordnet 7 .  ...
