Ranking Text Units According to Textual Saliency, Connectivity and Topic Aptness

An efficient use of lexical cohesion is described for ranking text units according to their contribution in defining the meaning of a text (textual saliency), their ability to form a cohesive subtext (textual connectivity) and the extent and effectiveness to which they address the different topics which characterize the subject matter of the text (topic aptness). A specific application is also discussed where the method described is employed to build the indexing component of a summarization system to provide both generic and query-based indicative summaries.
