Greynir is a natural language processing engine that extracts processable information from Icelandic text, allows natural language querying of that information and facilitates natural language understanding.
Greynir periodically scrapes chunks of text from Icelandic news sites on the web. It employs the Tokenizer and ReynirPackage modules (by the same authors) to tokenize the text and parse the token streams according to a hand-written context-free grammar for the Icelandic language. The resulting parse forests are disambiguated using scoring heuristics to find the best parse trees. The trees are then stored in a database and processed by grammatical pattern matching modules to obtain statements of fact and relations between stated facts.
