Aggregation by Conflation of Quasi-Synonymous Units in Author Abstracting

Actes de la 8ème conférence sur le Traitement Automatique des Langues Naturelles. Articles longs

In text generation, studies on aggregation often focus on the use of connectives to combine short made-up sentences. But connectives restrict the number of units that may be combined at any one time. So, how does information get condensed into fewer units without excessive use of connectives? From a comparison of document and abstract, this reconnaissance study reports on some preferred patterns in aggregation when authors write abstracts for journal articles on biology. The paper also discusses some prerequisites and difficulties anticipated for abstracting systems. More sentences were aggregated without than with the use of an explicit sign, such as a connective or a (semi-)colon.

Just What May be Deleted or Compressed in Abstracting?

Abstracts constituted from extracted sentences contain unneeded information that may be deleted, or compressed into simpler units. By comparing full text sentences used in abstracting with correspond-ing sentences in abstract, the study found such units to include metadiscourse phrases, parenthetical texts, redundant units inserted for emphasis, or are repetitions. Apposed texts and units such as modifiers and relative clauses which provide details and precision in the full text, but are out of place in an abstract, are also deleted.
