Estimating the Selectivity of XML Path Expression with Predicates by Histograms
Selectivity estimation of path expressions in querying XML data plays an important role in query optimization. A path expression may contain multiple branches with predicates, each...

Indexing XML Data with ToXin
Indexing schemes for semistructured data have been developed in recent years to optimize path query processing by summarizing path information. However, most of these schemes can ...

LZ77-Like Compression with Fast Random Access
We introduce an alternative Lempel-Ziv text parsing, LZ-End, that converges to the entropy and in practice gets very close to LZ77. LZ-End forces sources to finish at the end of ...
