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 topol-ogy, and lexical statistics. In the paper we show two versions of our algorithm, which have been evaluated against the results produced by(More)
The reasons why an author cites other publications are varied: an author can cite previous works to gain assistance of some sort in the form of background information, ideas, methods, or to review, critique or refute previous works. The problem is that the best possible way to retrieve the nature of citations is very time consuming: one should read article(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)
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)
Recently, several ontologies have been introduced for semantic publishing. However, scholarly publishing, like other real-world domains, needs to be described also in terms of precise temporal durations and the particular contexts in which the relevant processes take place. For instance, a document changes status during its publication process, e.g., from(More)
Overlapping structures in XML are not the symptoms of a misunderstanding of the intrinsic characteristics of a text document, nor the evidence of extreme scholarly requirements far beyond those needed by the most common XML-based applications. On the contrary, overlaps have started to appear in a large number of incredibly popular applications hidden under(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)
Scholarly publishing is in the middle of a revolution based on the use of Web-related technologies as medium of communication. In this paper we describe our ongoing study of semantic publishing and automatic annotation of scholarly documents, presenting several models and tools for the automatic annotation of structural and semantic components of documents.(More)
XML is among the preferred formats for storing the structure of documents such as scientific articles, manuals, documentation, literary works, etc. Sometimes publishers adopt established and well-known vocabularies such as DocBook and TEI, other times they create partially or entirely new ones that better deal with the particular requirements of their(More)
