    Structural and semantic similarity for XML comparison
    (Scopus, 2013) Guzman, Renato; Dongo, Irvin; Ticona Herrera, Regina
    XML has experimented a rapid growth mostly because of its application on the Web. Application varies from version control management, data storage to clustering and information retrieval. In this context, it is necessary to develop efficient techniques for comparing XML documents. Many method proposed are based only on structural commonalities, ignoring semantics. In this paper, we propose a new method for comparing XML documents based on LevelEdge combining tag structural and semantic similarities. © 2013 Authors.

    Toward RDF Normalization
    (Springer Verlag, 2015) Ticona Herrera, Regina; Tekli, Joe; Chbeir, Richard; Laborie, Sébastien; Dongo, Irvin; Guzman, Renato
    Billions of RDF triples are currently available on the Web through the Linked Open Data cloud (e.g., DBpedia, LinkedGeoData and New York Times). Governments, universities as well as companies (e.g., BBC, CNN) are also producing huge collections of RDF triples and exchanging them through different serialization formats (e.g., RDF/XML, Turtle, N-Triple, etc.). However, RDF descriptions (i.e., graphs and serializations) are verbose in syntax, often contain redundancies, and could be generated differently even when describing the same resources, which would have a negative impact on their processing. Hence, we propose here an approach to clean and eliminate redundancies from such RDF descriptions as a means of transforming different descriptions of the same information into one representation, which can then be tuned, depending on the target application (information retrieval, compression, etc.). Experimental tests show significant improvements, namely in reducing RDF description loading time and file size. © Springer International Publishing Switzerland 2015.
