=== Adpositions as attributes ===

Adpositions are also represented as attributes when they assign specific values to general relations. For instance:
+
 
+
;the book is in the box
+
:the relation "plc" (place) is sufficient to represent the meaning intended by "in" and no attribute is necessary: plc(book, box)
+
;the book is under the box
+
:the relation "plc" (place) is too generic to represent the meaning intended by "under" and the attribute @under is necessary? plc(book, box.@under)
+
 
+
 
+
For the time being, adpositions have been represented by their English correspondents.

Adpositions are connecting words used for a wide range of syntactic and semantic functions, most commonly modification and complementation.

Natural Language

Natural language adpositions are classified as prepositions, when preceding a phrase; as postpositions, when following a phrase; and as circumpositions, when surrounding a phrase:

UNL

Natural language adpositions are expected to be explicitly represented in UNL by Universal Relations or by Universal Relations and Universal Attributes:

  • the book of John = pos(book,John) (preposition represented as a relation)
  • the book about John = cnt(book,John) (preposition represented as a relation)
  • He lives in Geneva = plc(live,Geneva) (preposition represented as a relation)
  • He died in 1956 = tim(died,"1956") (preposition represented as a relation)
  • He is going to Geneva = gol(go,Geneva) or plc(go,Geneva.@to) (preposition represented as a specific relation ("gol") or as a general relation ("plc") and an attribute)
  • He has been working since Saturday = tmf(work,Saturday) or tim(work,Saturday.@from) (preposition represented as a specific relation ("tmf") or as a general relation ("tim") and an attribute)
  • The book near the table = plc(book,table.@near) (preposition represented as a relation and an attribute)
  • The book under the table = plc(book,table.@bottom.@contact) (preposition represented as a relation and attributes)
  • The book below the table = plc(book,table.@bottom.@near) (preposition represented as a relation and attributes)
