Xml Keyword Query

Query evaluation and query semantics in the XML keyword query, has an important role, which directly affect the performance of XML query. This paper proposes a fast approach for SLCA in keyword query over XML document,which can judge the information of relevant nodes by means of self-definition to document nods type.This method can solve the problems of no significance of node information query results of the XKSearch algorithm, and compared with XSeek algorithm, it has high efficiency in the query time consumed for the returned results. Experiments show that this method is more efficient in query time and quality of keywords query.

In this paper, from the perspective of XML data management, first in the HDFS store large amount of data and XML data based on XML data query rewrite the traditional framework of MapReduce process, the design of large amount of data XML data set keywords retrieval algorithm, contain XML data classification and coding, index and search a four parts, solve the large amount of data of the XML document keywords retrieval problem. Then the design and implementation based on MapReduce of large amount of data XML keyword query system.
