The search accuracy and completeness of the algo-
rithms were conducted by selecting one hundred
XQuery queries and then transforming them to key-
word queries using the terms of the XQuery queries as
keywords. Then, the results of XQuery queries were
used as the baseline to compute the precision and recall.
The results of the search accuracy are illustrated in
Table 1. The results show that the presented methods
achieve higher search accuracy due to the effective
ranking mechanism
