Profile

After obtaining my MSc from the University of Birmingham, I have been working as a researcher in the areas of text mining and Semantic Web in the Department of Computer Science, the University of Sheffield. My earlier research looked at text mining and Semantic Web technologies within domain-specific context, such as archaeology, aerospace engineering, automobile and consumer electronics.

Since 2012 I have been focusing on text mining on the Web, particularly methods for automatically creating and linking structured knowledge bases, and information extraction from the social media resources. During my post as researcher, I also obtained my PhD degree as a part-time staff candidate. Between late 2016 and 2017, I worked as a lecturer in Computer Science at the Computing and Technology Department, Nottingham Trent University.

I joined the Information School as a lecturer in January, 2018.

Research interests

My research addresses methods that enable machines to extract human knowledge from text, to represent such knowledge in a structured representation that is understandable and usable by machines. This ultimately enhances our capability of processing and sense-making of very large scale data, improving decision making. Specifically, this includes but is not limited to:

  • Information Extraction: how to automatically turn unstructured, natural language text into structured representation that could support machine understandability and reasoning. This could include the extraction of terms, concepts, named entities, and relations between them from texts.
  • Disambiguation: how to teach machines to automatically infer the meaning of a word or phrase within certain context.
  • Lexical semantics: how to represent the ‘meaning’ of a word, name, phrase, or sentence; how to measure the relatedness and similarity of these meanings (semantic relatedness and similarity).
  • Knowledge base construction: the use of all the above technology in the automatic creation of structured ‘databases’ that support machine understandability and reasoning; and methods of mapping such knowledge bases (ontology alignment, ontology mapping). An example of a knowledge base is the Google Knowledge Graph, or DBpedia.
  • Semantic Web and Linked Data: the use of all the above technology to enable the vision of tomorrow’s Web where machine understandable data are put on the Web, shared and reused across application, enterprise, and community boundaries.
