 Combining Structure- and Content-Based Algorithms for XML Query Processing

abstract    One of key benefits of XML is its ability to represent both structured and unstructured(text) data. Although current XML query languages such as XQuery/XPath can express rich queries over structured data, they lack IR-related features for querying over text data. In this talk, we will present TeXQuery, a full-text extension to XQuery, which provide a rich set of composable full-text search primitives. TexQuery enable users to query over both structured and text data simultaneously by seamlessly embedding these TeXQuery primitives in XQuery data model. Furthermore, TexQuery supports diverse implementation-dependent scoring mechanisms through a common interface and we will discuss a flexible IR scoring mechanism in XML.
