Semantic publishing is the use of Web and Semantic Web technologies to enhance the meaning of a published journal article, to facilitate its automated discovery, to enable its linking to semantically related articles, to provide access to data within the article in actionable form, and to facilitate integration of data between articles. Recently, semantic(More)
In this paper we propose a novel approach to markup, called Extreme Annotational RDF Markup (EARMARK), using RDF and OWL to annotate features in text content that cannot be mapped with usual markup languages. EARMARK provides a unifying framework to handle tree-based XML features as well as more complex markup for non-XML scenarios such as overlapping(More)
Observational studies in the literature have highlighted low levels of user satisfaction in relation to the support for ontology visualization and exploration provided by current ontology engineering tools. These issues are particularly problematic for non-expert users, who rely on effective tool support to abstract from representational details and to be(More)
In this paper we address the issue of identifying the concepts in an ontology, which best summarize what the ontology is about. Our approach combines a number of criteria, drawn from cognitive science, network topology, and lexical statistics. In the paper we show two versions of our algorithm, which have been evaluated against the results produced by human(More)
The XML documents that represent legal resources contain information and legal knowledge that belong to many distinct conceptual layers. This paper shows how the Akoma Ntoso standard keeps these layers well separated while providing ontological structures on top of them. Additionally, this paper illustrates how Akoma Ntoso allows multiple interpretations,(More)
We have established two cell lines, PER-452 and PER-453, from an 8-month-old girl with an extensive pineoblastoma. Characterization of these lines revealed that the proto-oncogenes MYC and MYCN were not amplified, but both cell lines showed MYCN expression comparable to a cell line with 200-fold MYCN amplification. Both cell lines contained an i(17q). These(More)
An expressed luciferase viability assay (ELVA) has been developed for cell viability and cell number based on detecting the expression of luciferase transfected into the cells. Stable transfectants were produced that expressed luciferase constitutively. Like many endogenous enzymes, luciferase is rapidly degraded following cell death, so that the enzyme can(More)
The RDF collections and containers is one of the most used features by RDF technicians and practitioners. Although some work has been published in past, there is not a standard and accepted way for defining collections within OWL DL frameworks. Here, we attempt to address this issue with the introduction of the Collections Ontology (CO) version 2.0. CO is(More)
SHELDON is the first true hybridization of NLP machine reading and the Semantic Web. It extracts RDF data from text using a machine reader: the extracted RDF graphs are compliant to Semantic Web and Linked Data. It goes further and applies Semantic Web practices and technologies to extend the current human-readable web. The input is represented by a(More)
