“…Also, as this paper makes apparent, attribute grammars can be used as general-purpose XML-processing artifacts. This contrasts with approaches like [6] [12], where attribute grammars are applied to more specific XML-processing tasks (e.g., query evaluation or information retrieval). In this way, the approach presented in this paper is similar in spirit to [16].…”

Applications based on web services make an extensive use of XML documents. These XML documents are structured according to different markup vocabularies, which represent information such as the inputs and the outputs of the services. This paper proposes a way of implementing web services using a framework called XLOP (XML Language-Oriented Processing). XLOP includes a declarative domain-specific language based on attribute grammars, a well-known declarative specification technique used in the development of language processors. XLOP makes possible the automatic generation of efficient XML-processing components from high-level, declarative specifications, facilitating the development of the aforementioned services and enhancing their maintainability. This technique is illustrated in the context of Chasqui, a system for building repositories of learning objects in specialized domains, which implements a REST web service for checking constraints on the metadata of the stored learning objects.

“…Then, the weight of a query term in the document vector is calculated by a weight method, for example, the term frequency‐inverse document frequency method. Finally, the total relevance score between the query vector and document vector is computed with a cosine function [15].…”

Improved document ranking in ontology‐based document search engine using evidential reasoning

This study presents a novel approach to document ranking in an ontology-based document search engine (ODSE) using evidential reasoning (ER). Firstly, a domain ontology model, used for query expansion, and a connection interface to an ODSE are developed. A multiple attribute decision making (MADM) tree model is proposed to organise expanded query terms. Then, an ER algorithm, based on the Dempster-Shafer theory, is used for evidence combination in the MADM tree model. The proposed approach is discussed in a generic frame for document ranking, which is evaluated using document queries in the domain of electrical substation fault diagnosis. The results show that the proposed approach provides a suitable solution to document ranking and the precision at the same recall levels for ODSE searches have been improved significantly with ER embedded, in comparison with a traditional keyword-matching search engine, an ODSE without ER and a non-randomness-based weighting model.
