Aggregation removes redundant information from a text without changing the content. The generated natural language text becomes concise and non-redundant and hence easy to read.
Aggregation is carried out with assistance of a number of aggregation rules.
Aggregation has never been thoroughly investigated. The domain investigated is formal specifications of computer systems specifically for telecom systems and the validation of these with natural language generation. To aim of this project is to find these aggregation rules and try to apply them on any text to make the text concise. This is carried out by studying various text plans used in natural language generation systems and by studying various occurring texts and from this material extract the aggregation rules.
