Just What is Aggregation Anyway? - Reape, Mellish (Correct)
....and implementation based on a corpus study. Shaw s work has changed recently ( Sha98a] Sha98b] Rather than implementing aggregation rules directly in the planner, the planner marks recurring elements and lets the realizer decide which elements to realize or not. 6. 5 Lexical aggregation [Cah98] is a study of lexicalisation (lexical choice) in applied NLG systems. There Cahill makes a distinction between lexicalisation and true lexical choice . We do, however, differentiate between lexicalisation and lexical choice .

....and true lexical choice . We do, however, differentiate between lexicalisation and lexical choice . The first we take to indicate a broader meaning of the conversion of something to lexical items, while the second we use in a narrower sense to mean deciding between lexical alternatives. Cah98, p. 1] Following Cahill s lead, we distinguish two potential steps in any lexicalisation lexical choice process: 1. the mapping from conceptual predicates and structure to lexical predicates and structure (LEX) and 2. the choice of particular lexemes to realize those lexical predicates and ....

....are generated in context, see [8] But is D2S also well founded This depends on what it means for an NLG system to be well founded. If it means that every decision made by the system (e.g. expressing a proposition in one or in two sentences, using passive or active voice; lexical choice [2]) should be based on sound linguistic principles, then no NLG system we are aware of qualifies as being even remotely well founded: the gap between raw data and text is bridged in ways that are often arbitrary. Many NLG systems use linguistic principles, but typically such sophistication is ....

....what aspects of abstract syntactic representation are determined by TLC. Some progress on this can probably now be made, given the detailed specification of some of the levels of representation later in this document. Lexicalisation is assumed to take place in general in two stages, LEX and TLC [Cahill 1998]. Aggregation is considered to be a generic operation that is implemented by a family of operators, one for every level of representation [Reape 1999a] This means that most levels of representation need to allow for the representation of aggregated structures . 1.5 Access to other Knowledge ....

....a narrower sense to mean deciding between lexical alternatives. Not all of the systems we looked at perform genuine lexical choice , so we have opted for the term lexicalisation to cover the phenomena we are discussing here. More detailed discussion of lexicalisation in the given systems is in [Cah98] 2.2 Aggregation This can have more or less specific interpretations. On one very general reading, it can be taken to mean the putting together of two pieces of information. On a narrower interpretation it can mean the putting together of sentences. Within the context of RAGS, it does not make ....
