Abstract
Traditional query languages proposed for semistructured data models such as OEM (Object Exchange Model) require queries to find exact matches. These queries fail to return the results in case the query paths specified do not completely match the paths in the database. In other words, a query, whose paths are {ıt over- or under-specified,} fails to retrieve results. It is possible that the users may not be aware of the structure or schema of the semistructured data or schema may have been changed since it was queried last time. In this paper, we discuss the cooperative query processing techniques in case of semistructured data. We explore our ideas with the help of examples and provide some overview of the algorithms to process such queries.
