Nearest Keyword Search in XML Documents

Summary: Introduces Nearest Keyword (NK) search on XML trees and an index that returns the nearest keyword node to a query node. Delivers logarithmic query time in the number of keyword-bearing nodes with linear space and fast construction, with experiments validating NK as a practical building block for XPath and keyword search.
