Processing of unstructured web content
- NLP Basics – Tokenisation, Part of Speech Tagging, Chunking, Stemming, Lemmatization
- Web contents and their characteristics – diverse genres of web contents, e.g. personal web sites, news sites, blogs, forums, wikis
- Web contents and their characteristics – continued
NLP applications for the web
- Information retrieval – introduction to the basics of information retrieval
- Web information retrieval – natural language interfaces for web information retrieval
- Question answering (QA): Factoid QA, Knowledge Base QA, Community QA
