A Scalable Architecture for XML Retrieval.
Gabriella Kazai, Thomas Rölleke · 2002
While in classical text collections documents are regarded as atomic units, in XML collections nested elements of varying granularity are considered. This augmented view increases the number of potentially retrieved objects, e.g. documents, elements within documents, or aggregations of elements or of documents. The increase in the number of objects to be indexed and retrieved by XML retrieval systems leads, for XML collections of comparably small size (several 100 MB), already to the necessity to apply strategies for scalability, such as parallel and distributed processing, term, document and database pre-selection. We report in this paper on our approach for dealing with XML collections in general, and with the INEX collection in particular, using a scalable indexing and retrieval architecture.
