Collectivity & distributivity

The opposition 'separately' / 'together' manifests itself in different parts of the linguistic system-in the interpretation of noun phrases (distributive vs. collective), in syntax (200 roubles a piece, 100 kilometres per hour), in the lexicon (together, jointly, collectively, in aggregate, common, collective; apart, separate, apart, separately, each, etc.) in word formation (coauthor).We discuss these meanings in the context of developing a computational model of semantic analysis that highlights the following issues: 1) What information about the meaning of distributive/collective NPs should be available to the parser for reasoning?2) What valency slots are characteristic of the meanings 'together' / 'separately' and how are they instantiated in syntactic constructions and lexical items?
