Commonsense Aboutness for Information Retrieval
Information retrieval (IR) is driven by a process which decides whether a document is about a query. Recent attempts have been made to formalize properties of “aboutness”, but no consensus has been reached. The properties being proposed are largely being determined by the underlying model. Once the framework has been fixed, certain aboutness properties could be implied from it. Moreover, some p...
متن کاملXML Retrieval
DEFINITION Text documents often contain a mixture of structured and unstructured content. One way to format this mixed content is according to the adopted W3C standard for information repositories and exchanges, the eXtensible Mark-up Language (XML). In contrast to HTML, which is mainly layout-oriented, XML follows the fundamental concept of separating the logical structure of a document from i...
متن کاملA commonsense aboutness theory for information retrieval modeling
Information retrieval (IR) can be viewed as a process to determine the “aboutness”, or sometimes “relevance”, relationship between information carriers (e.g. document and query). Thus, the concept of aboutness lies at the heart of IR. A better understanding of aboutness would lead to more effective IR systems. In this paper, we give a review of the status of current research on aboutness. It is...
متن کاملRelevance Feedback in XML Retrieval
Highly heterogeneous XML data collections that do not have a global schema, as arising, for example, in federations of digital libraries or scientific data repositories, cannot be effectively queried with XQuery or XPath alone, but rather require a ranked retrieval approach. As known from ample work in the IR field, relevance feedback provided by the user that drives automatic query refinement ...
متن کاملContext Driven XML Retrieval
This paper presents a data-centric approach to XML information retrieval which benefits from XML document structure and adapts traditional text-centric information retrieval techniques to deal with text content inside XML. We implement our ideas in a configurable, general purpose XML retrieval library which can be tuned to operate on multilingual XML resources with different structure and can b...
