Corpus search These notes introduce some practical tools to find patterns regular expressions A general formalism to represent finitestate automata the corpus query language CQL CQP. Corpora and Statistical Methods. In this lecture. Corpora and Statistical Methods. We have considered distributions of words and lexical variation in corpora.. Today we consider collocations:. definition and characteristics. LIN 1180 – Semantics. Lecture 8. Hyponymy and other relations. Part 1. Definition of hyponymy. LIN 1180 -- Semantics. Hyponymy is a . relation of inclusion. .. Arrows can be interpreted as “IS-A” relations.. LIN1180 Semantics. Lecture 4 . Reference and proper names. Continuation of last week. Proper names. Semantics -- LIN 1180. These . seem to be “purely referential”, establishing a direct relationship to things/people in the world.. LIN3021 Formal Semantics. Lecture . 9. In this lecture. Noun phrases as g. eneralised quantifiers: some further concepts. What we’ve said so far. In a. sentence of the form . [[. Det. . NP. ]. subj. LIN3021 Formal Semantics. Lecture 8. In this lecture. Noun phrases as g. eneralised quantifiers. Part 1. A bit of motivation. Not all NPs are referential. We’ve mainly considered NPs that refer (i.e. Pick out an individual or a kind) in some sense:.

LIN 1180 – Semantics. Lecture7. Ambiguity and vagueness. Continuation from last week. Ambiguity vs. Vagueness (I). In context, a word can seem to have several distinct senses. Some may appear more related than others.. LIN3022 Natural Language Processing. Lecture 9. In this lecture. We continue with our discussion of parsing algorithms. We introduce dynamic programming approaches. We then look at . probabilistic context-free grammars. Lecture . 5. In this lecture. We begin to consider the problem of . lexical acquisition . beyond collocations. syntax-semantics interface:. verb subcategorisation frames. prepositional phrase attachment ambiguity.
