Apologies; having read the full paper you are correct. This paper is describing a technique to query Semantic Hierarchical Trees (SHTs) constructed from documents. I would say that the data itself *is* structured, it just exists in an unstructured medium, but now I'm just arguing...semantics. That being said I suspect they didn't think ShtDB would catch on very well, and so went with ZenDB. Shame really.
