Abstract:
XML retrieval, also referred to as Structured
Document Retrieval is a discipline of information
retrieval that focuses on the retrieval of relevant
document fragments for a given information need
that contains both content and structural
components. In this paper, a system that can
provide structured document retrieval for XML
document is developed in order to enable the user
to find the relevant XML fragment with structure
and content queries. Structured XML documents
and path based simple queries are as the system
inputs. This system aims to retrieve the relevant
XML fragments; a relevance values propagation
method is used.Relevance propagation method is
to evaluate the relevance values of each leaf node
according to the content condition of query and
propagate relevance values along the document
tree until a node having the query tag name is
found. The main objective of proposed method is
to retrieve the relevant XML fragments for user
query. The experiment of the system shows the
comparison of querying times and relevant XML
fragments are ranked.
