Abstract
One aspect of the present invention is a system for classifying element nodes in a subtree-structured XML database. The XQE structural-textual classification system is sensitive to both the textual resemblance between document elements as well as the structural resemblance between document elements. The XQE structural-textual classification system might use the XQE parent-child index described in Lindblad II-A for the purpose of forming vectors of “terms” which encode both the structural and the textual content of XML elements. The element vectors are processed by a classifier to create class prototype vectors which can be used to classify elements as they are added to the database.
Claims6
In an XML handling system, wherein XML datasets are stored in structured forms, a computer-implemented method of characterizing an XML dataset comprising:
- examining the XML dataset to find a match against a content sequence query expression;
- examining the XML dataset to find a match against a content structure query expression;
- and
- classifying the XML dataset into one or more of a plurality of classifications, wherein the classifying of the XML dataset is dependent on whether the content sequence query expression is found and on whether the content structure query expression is found.
In software running on general-purpose processors, wherein XML datasets are stored in structured forms, a computer-implemented method of characterizing an XML dataset comprising:
- examining the XML dataset to find a match against a content sequence query expression;
- examining the XML dataset to find a match against a content structure query expression;
- and
- classifying the XML dataset into one or more of a plurality of classifications, wherein the classifying of the XML dataset is dependent on whether the content sequence query expression is found and on whether the content structure query expression is found.
