Paper title: 
"Tree-Based Document Representation for Passage-Based Retrieval" 

Abstract: 
"Passage-based document retrieval has shown mixed results when it is 
applied to a variety of test beds. One important reason for this 
inconsistent performance is the lack of a general framework for 
extraction of pieces of information at all levels of granularity. I 
present utility of a simple tree-based method for organizing information in 
document that aims to extract coherent, complete, and concise pieces 
of information from a document at many levels of 
granularity. Documents are scored based on their best matching pieces 
of information. An extensive set of experiments has been performed on 
four different TREC collections to show the effectiveness of simple 
tree-based method for document retrieval. I have compared 
tree-based method to both standard passage retrieval and 
state-of-the-art passage retrieval models. Empirical results show that 
the performance of tree-based method exceeds the performance of baseline 
passage-based retrieval methods and it equals or exceeds the 
performance of much more complicated state-of-the-art passage models."
