These assumptions break down in newer federated and Internet based query environments, that are targeted by the Telegraph dataflow engine [25] and other systems that support queries over remote data sources (e.g. [14, 19]) In these environments, di#erent data sources of varying performance can be joined in a single query, and the production of a single complete output row may be blocked by delays or rate mismatches across sources. In such scenarios, useful results from fast sources could still be made available ....
....relationships between sources. As a result, public interfaces for Internet query processors typically allow queries to be specified imprecisely. In the FFF demo we provided a set of broad, canned queries that we believed would satisfy a large number of users. The Niagara Internet Query System [19] suggests an interface where sources in a query are automatically generated by looking up user specified keywords in a catalog of all sources. The cooperative database literature has long argued for looser modes of query specification (e.g. 28, 18, 7] where the system aids the user in ....

In fact, in a document representation of the database, a sub tree corresponds to a contiguous fragment of the document.As such, the determination of parent child and ancestor descendent containment relationships is a very frequent operation in XML query processing. It has been observed [43,12,2] that it is possible to associate a numeric start and end label with each data node in the database, defining a corresponding interval between these labels such that every descendant node has an interval that is strictly included in its ancestors interval. If each node is also labeled with its ....

....to effectively tap into the large amounts of data stored in XML databases around the globe are going to be crucial to fulfilling the full potential of XML and enabling Internet scale applications. Realizing such Internet scale XML query processors (like, e.g. Xyleme (www.xyleme.com) or Niagara [17]) in turn, hinges on providing effective support for high level, declarative XML query languages. A variety of languages have been proposed for querying semistructured and XML databases, including XQuery [4] Lorel [15] and UnQL [3] A common characteristic of all existing language proposals, is ....

The techniques described in [17] have the further advantage of not being in memory, but their heuristic approach can not guarantee the correct answer. Other related work. There have been several attempts to add keyword search to XML query languages [8, 11, 12], but these languages support only boolean lters, not ranked query results. More closely related are XXL [16] an SQL like language, XIRQL [9] and Hayashi et al. s XML query language [10] These languages return results ranked by textual similarity, but they do not appear to support similarity ....

The first approach uses special purpose query engines and repositories for semi structured data [15] 20] [21]. These database systems are built from scratch for the specific purpose of storing and querying XML documents. This approach, however, has two potential disadvantages. Firstly, native XML database systems do not harness the sophisticated storage and query capability already provided by existing 2 ....

....predates XML, and lacks the clear structure and elegance of the recently developed XML query languages such as XML QL. Furthermore, although an in depth comparison is beyond the scope of this paper, it appears that this older work resulted in less expressive languages. In parallel to our work, [NDM 00] have proposed to combine XML querying with an IR search engine. However, the IR capabilities considered there are limited to simple containment predicates and seem to follow a Boolean retrieval paradigm (at least [NDM 00] does not mention anything about support for ranked retrieval) The rest ....

With a large amount of data represented as XML documents, it becomes necessary to store and query these XML documents. To address this problem, there has been work done on building native XML database systems [6][9]. These database systems are built from scratch for the specific purpose of storing and querying XML documents. This approach, however, has two potential disadvantages.
