Information retrieval is the process of storing textual data, i.e., documents, and
then retrieving information from these stored documents. Web-based retrieval
systems that use XML documents can also retrieve specific portions of the
documents which are considered to be relevant to a query. This is called element
retrieval which is performed using flexible retrieval (Flex)  in this thesis.
In this thesis we focus on improving the results of the INEX 2009 Thorough Task
and the INEX 2010 Efficiency Task. Experiments are performed, methodology is
described, and results are reported. Since flexible retrieval (Flex) depends on
Lnu-ltu term weighting , experiments which generate the best values for the
required parameters (i.e., slope and pivot) are also briefly described. Using the
best value of slope, the INEX 2009 Thorough Task and the INEX 2010 Efficiency
Task are carried out and the results are reported.
