[edit] Set and Function
- set and functional (lamda) definition: interchangeable
- set: only 'in' or 'out', not 'undefined'
- useful in presuppositions
- -> function view more handy
- relations can be expressed as functions
[edit] Currying/Schönfinkelization
- [|parent|] as function
y is a parent of x
y is a parent of x
- advantages
- arguments are normally not symmetric
- one argument is usually closer than the other
[edit] Binary Branching
- [|Hannes likes Cassandra|] denotated: [|like|]([|Cassandra|])
[
[y likes x]]
- Evidence for binary branching can be accounted for by this mechanism.
- Transitive Verbs
- add to lexicon: function that takes individual first and then a function (like an intransitive verb)
[edit] Semantic Types
- e = entitiy
- t = truth value
- -> saturated denotations, basic types
- <e,t> functions form individual to truth values
- <e,<e,t>> functions ...
- <t,t> 'it is not the case that'
- <t,<t,t>> 'and', 'or'
- -> unsaturated denotations
- D_e = domain of e, etc.
- -> new rule: type driven interpretation
[edit] General Semantic Principles
- TN
- If
is a terminal node and
is in the domain of
, then
is given in the lexicon.
- If
- NN
- non-branching
- FA
- branching
- Interpretability principle
- A tree
is interpretable iff all of its nodes are in the domain of
.
- A tree
[edit] Syntax & Semantics
