a query expansion method based on sentences and a sentence vectors combination strategy are proposed to improve the query performance.A distributed text retrieval system DQSSQE is designed based on Microsoft HPC Server platform and query expansion strategy.The experiment result shows that the proposed query expansion strategy improves the precision ration greatly
and improves the recall ratio as well.At the same time
DQSSQE system gets a higher computation speedup ratio
and the more large the text set is
the higher performance the system will get
compared to the ordinary text retrieval systems.
