Course objectives
At the end of the course students should be able to: understand the concept of sense and different types of sense; understand the ambiguity and its processing in current computer programs; understand sense disambiguation in current dictionaries as well as in computer processing; know traditional and current approaches to word sense disambiguation; explain the role of context in sense disambiguation; understand the formalisms for knowledge representation; know current approaches and computer programs for semantic analysis and understand a particular group of programs that use different approaches (i.e. chatbots)
Learning outcomes
The student will be able to: - identify a natural language processing problem as a problem of semantic processing,
- consider the granularity of a language resource and compare it with other resources,
- detect size and type of context relevant to a particular task,
- apply statistical methods for keyword detection
Syllabus
  • Introduction to sense study. Signs and senses. Types of sense.
  • Homonymy and Polysemy. Is the sense space discrete? Is the ambiguity a real problem?
  • Sense in dictionaries, sense in text, “one-sense per collocation” assumption, machine learning approaches, sense definition comparison.
  • Word sense disambiguation (WSD), the SENSEVAL contest, WSD algorithms, whan does WSD work? Problems with WSD: granularity, subjectivity.
  • Formalisms for describing sense: semantic features, selectional restritions, taxonomies, semantic frames and scripts, asociative and semantic networks, verb valency lexicons. WordNet and other resources.
  • The role of the context, formalisms, relations between senses, domains, context vectors.
  • Mathematical sense modelling and context modelling.
  • Particular programs that aggregate different approaches to semantic analysis Sense and emotions, emotional computing. From word meanings to the meaning of the discourse
