Pitfalls of non context-driven XML search systems

A data element specifies one of the characteristics of its parent element. Therefore, the context of a data element is determined by its parent. Non context driven search engines build relationships between data nodes based solely on their labels and proximity to one another while overlooking their contexts. Therefore, they may return faulty answers. This paper investigates the pitfalls and limitations of non context-driven XML search engines, which caused by overlooking elements´ contexts. The paper demonstrates these pitfalls and limitations using sample of queries and three non context-driven search engines.
