quality, which applies to the majority <strong>of</strong> the glosses, is used to <strong>in</strong>dicate that<br />

there is no agreement between the two parsers that have been used to parse<br />

the <strong>in</strong>put def<strong>in</strong>ition, and that there has been no manual check<strong>in</strong>g <strong>of</strong> the output.<br />

"Gold" quality means manual check<strong>in</strong>g has been performed, and "silver"<br />

quality <strong>in</strong>dicates that there has been no manual check<strong>in</strong>g but the two parsers<br />

agree <strong>in</strong> their representation. The importance given to the agreement between<br />

the two constituency parsers, is due to the fact that LFs are a mapp<strong>in</strong>g on<br />

syntactic constituency representation.<br />

LF from glosses is represented <strong>in</strong> different manner accord<strong>in</strong>g to lexical<br />

category, adjective, verb, noun and adverb: each one is associated to a<br />

predicate but with some differences. As far as verbs are concerned we have<br />

the follow<strong>in</strong>g picture:<br />

For each synset, a variable 'e1' is associated to the first term that represents it,<br />

to <strong>in</strong>dicate the eventuality <strong>of</strong> the action/state/event <strong>of</strong> the verb mean<strong>in</strong>g; the<br />

subject is associated <strong>in</strong>variably to 'x1' and the object to 'x2'. The second<br />

argument may be fictitious <strong>in</strong> case <strong>of</strong> <strong>in</strong>transitive verbs.<br />

recognize:VB(e1, x1, x2) -> show:VB(e1, x1, x5) approval:NN(x3) or:CC(x5,<br />

x3, x4) appreciation:NN(x4) <strong>of</strong>:IN(x5, x2)<br />

In this case all variables are bound to some argument position and are<br />

associated to some l<strong>in</strong>guistic element.<br />

In the case <strong>of</strong> ditransitive verbs the LF representation <strong>of</strong> the event is<br />

verb(e1,x1,x2,x3), as <strong>in</strong>, pr<strong>of</strong>essor gives students the grades: pr<strong>of</strong>essor(x1 )<br />

give( e1, x1, x2, x3 ) grade(x2) student (x3), however this representation is not<br />

the rule. This issue constitutes by itself a thorny problem even at a theoretical<br />

level (but see Pustejovsky 1991;2000), so I will start by <strong>in</strong>troduc<strong>in</strong>g the topic<br />

and then I will delve <strong>in</strong>to the way <strong>in</strong> which it has been treated <strong>in</strong> XWN. There<br />

are at least four different types <strong>of</strong> three-place predicates (hence 3PPs):<br />

a. PUT, John put the book on the table<br />

b. STRIP, John strips capital ga<strong>in</strong>s from the bill<br />

c. CONSIDER, John considers Mary silly<br />

d. CAUSE, John caused the car to stop<br />

These examples could be multiplied with other logically and lexically similar<br />

verbs and I will add one more example <strong>in</strong> the logical forms below. One also<br />

needs to stress the fact that example c. is a case <strong>of</strong> secondary predication<br />

which is semantically identical to "John pa<strong>in</strong>ted the house black", but<br />

lexically totally different. The verb PAINT is just a transitive verb, which can<br />

at times receive secondary predication, though necessarily semantically viable,<br />

like a colour "BLACK". The verb CONSIDER is lexically speak<strong>in</strong>g, a 3-place<br />

predicate, i.e. a special type <strong>of</strong> transitive verb. Special treatment is required<br />

also for "perception verbs" like SEE and others that we discuss <strong>in</strong> detail below.<br />

What is important now, is to highlight the lexical structures <strong>of</strong> each case: Case<br />

A. has a Subject, an Object and an Oblique which is an Oblique complement<br />

and is Obligatory. Differently from Case B. where the verb STRIP has an<br />

Oblique which is an Optional argument. Case A. could also be exemplified by<br />

verbs like GIVE, TELL, PROMISE etc. – as for <strong>in</strong>stance <strong>in</strong> “John gave Mary<br />

a book” - which can exhibit a double object construction <strong>in</strong> addition to the<br />
