Ontology-based integration of XML data: Schematic marks as a bridge between syntax and semantic level
2007
This paper presents an ontology integration approach of XML data. The approach is composed of two pillars the first of which is based on formal language and XML grammars analysis. The second pillar is based on ontology and domain ontology analysis. The keystone of this architecture which creates a bridge between the two pillars is based on the concept of schematic marks introduced in this paper. These schematic marks make it possible to establish the link between the syntactic level and the semantic level for our integration framework.
XML document-grammar comparison: related problems and applications
2011
10.2478/s13537-011-0005-1; International audience; XML document comparison is becoming an ever more popular research issue due to the increasingly abundant use of XML. Likewise, a growing interest fosters the development of XML grammar matching and comparison, due to the proliferation of heterogeneous XML data sources, particularly on the Web. Nonetheless, the process of comparing XML documents with XML grammars, i.e., XML document and grammar similarity evaluation, has not yet received the attention it deserves. In this paper, we provide an overview on existing research related to XML document/grammar comparison, presenting the background and discussing the various techniques related to th…
An overview on XML similarity: Background, current trends and future directions
2009
In recent years, XML has been established as a major means for information management, and has been broadly utilized for complex data representation (e.g. multimedia objects). Owing to an unparalleled increasing use of the XML standard, developing efficient techniques for comparing XML-based documents becomes essential in the database and information retrieval communities. In this paper, we provide an overview of XML similarity/comparison by presenting existing research related to XML similarity. We also detail the possible applications of XML comparison processes in various fields, ranging over data warehousing, data integration, classification/clustering and XML querying, and discuss some…
Extensible User-Based XML Grammar Matching
2009
International audience; XML grammar matching has found considerable interest recently due to the growing number of heterogeneous XML documents on the web and the increasing need to integrate, and consequently search and retrieve XML data originated from different data sources. In this paper, we provide an approach for automatic XML grammar matching and comparison aiming to minimize the amount of user effort required to perform the match task. We propose an open framework based on the concept of tree edit distance, integrating different matching criterions so as to capture XML grammar element semantic and syntactic similarities, cardinality and alternativeness constraints, as well as data-ty…
Transforming XML documents to OWL ontologies: A survey
2015
The aims of XML data conversion to ontologies are the indexing, integration and enrichment of existing ontologies with knowledge acquired from these sources. The contribution of this paper consists in providing a classification of the approaches used for the conversion of XML documents into OWL ontologies. This classification underlines the usage profile of each conversion method, providing a clear description of the advantages and drawbacks belonging to each method. Hence, this paper focuses on two main processes, which are ontology enrichment and ontology population using XML data. Ontology enrichment is related to the schema of the ontology (TBox), and ontology population is related to …
XCDL: an XML-oriented visual composition definition language
2010
International audience; XML data flow has reached beyond the world of computer science and has spread to other areas such as data communication, e-commerce and instant messaging. Therefore, manipulating this data by non expert programmers is becoming imperative. On one hand, Mashups have emerged a few years ago, providing users with visual tools for web data manipulation but not necessarily XML specific. Mashups have been leaning towards functional composition but no formal languages have yet been defined. On the other hand, visual languages for XML have been emerging since the standardization of XML, and mostly relying on querying XML data for extraction or structure transformations. These…

Climate Change and Global Justice: New Problem, Old Paradigm?
2014
In this paper, we focus on the conceptualization of climate change as an issue of global justice. While we do not deny that climate change raises fundamental and dramatic issues of justice among peoples as well as generations, our claim is that the language of global justice can obscure the fact that problems provoked by climate change lack some characteristic features of problems of global justice, while possessing others that are not characteristic of such problems. We begin by describing briefly how we got to where we are, climatically speaking; we go on to show why it is plausible to think of climate change as provoking problems of global justice; point out four respects in which this d…
Digital Palaeography of Hieratic
2020
After a short history of research into hieratic palaeography, the first experiences with digital methods to conduct the study of handwritten documents, in Egyptology as well as in other fields, are presented. The needs and goals of a future digital palaeography are then explained in detail. Such a palaeography is expected to become a modern research tool for ancient Egyptian handwritings that allows the depiction, description, classification, and encoding of cursive signs and that includes information about the entire manuscripts and their materiality. In constructing such a tool, some questions are essential, for instance: How should the signs be represented—as image sections from a scan o…
