Using efficient database technology (DB) for effective information retrieval (IR) of semi-structured text

Definition

Integrated DB&IR semi-structured text retrieval combines IR-style scoring and ranking methods for effective search with indexing techniques and processing algorithms from the database world for efficient query evaluation.

Historical Background

Database research has traditionally focused on semi-structured documents that represent structured data with a well-defined schema and only little unstructured, textual content (aka. “data-centric” XML). Typical examples for such documents are invoices, purchase orders, or even complete bibliographies.

Early work in the field concentrated on “classical” data management problems for XML: storing XML data in relational or native XML systems, defining query languages that integrate conditions on the structure and the content of results (like SQL for relational data), efficiently processing these queries on huge collections of...
