Foreground and Background Text in Retrieva

Our hypothesis is that certain clauses have foreground functions in text, while other clauses have background functions and that these functions are expressed or re- flected in the syntactic structure of the clause. Presumably these clauses will have differing utility for automatic approaches to text understanding; a summarization system might want to utilize background clauses to capture commonalities between numbers of documents while an indexing system might use foreground clauses in order to capture specific characteristics of a certain document.
