XML Structural Summaries
This tutorial introduces the concept of XML Structural Summaries and describes their role within XML retrieval. It covers the usage of those summaries for Database-style query processing and Information Retrieval-style search tasks in the context of both centralized and distributed environments. Finally, it discusses new retrieval scenarios that can potentially be favorably supported by those s...
متن کاملClustering XML Documents Using Structural Summaries
This work presents a methodology for grouping structurally similar XML documents using clustering algorithms. Modeling XML documents with tree-like structures, we face the ‘clustering XML documents by structure’ problem as a ‘tree clustering’ problem, exploiting distances that estimate the similarity between those trees in terms of the hierarchical relationships of their nodes. We suggest the u...
متن کاملThe Role of Structural Summaries for XML Retrieval
A Structural Summary of an XML document is a dynamically generated and maintained graph structure that preserves the structural characteristics of the document in a compact form. The versatility of structural summaries has been established with their extensive usage for diverse retrieval tasks. Within traditional XML query processing those structures have been used as primary indexes on the str...
متن کاملRepresenting User Navigation in XML Retrieval with Structural Summaries
This poster presents a novel way to represent user navigation in XML retrieval using collection statistics from XML summaries. Currently, developing user navigation models in XML retrieval is costly and the models are specific to collected user assessments. We address this problem by proposing summary navigation models which describe user navigation in terms of XML summaries. We develop our pro...
متن کاملStructural summaries as a core technology for efficient XML retrieval
The Extensible Markup Language (XML) is extremely popular as a generic markup language for text documents with an explicit hierarchical structure. The different types of XML data found in today’s document repositories, digital libraries, intranets and on the web range from flat text with little meaningful structure to be queried, over truly semistructured data with a rich and often irregular st...
