Ontology Construction from Online Ontologies

One of the main hurdles towards a wide endorsement of ontologies is the high cost of constructing them. Reuse of existing ontologies offers a much cheaper alternative than building new ones from scratch, yet tools to support such reuse are still in their infancy. However, more ontologies are becoming available on the web, and online libraries for storing and indexing ontologies are increasing in number and demand. Search engines have also started to appear, to facilitate search and retrieval of online ontologies. This paper presents a fresh view on constructing ontologies automatically, by identifying, ranking, and merging fragments of online ontologies

HTML Macros -- Easing the Construction and Maintenance of Web Texts

Authoring and maintaining large collections of Web texts is a cumbersome, error-prone and time-consuming business. Ongoing development of courseware for the High Performance Computing Consortium (HPCC) TLTP has only helped to emphasise these problems. Courseware requires the application of a coherent document layout (templates) for each page, and also the use of standard icons with a consistent functionality, in order to create a constant look and feel throughout the material. This provides the user with an environment where he or she can access new pages, and instantly recognise the format used, making the extraction of the information on the page much quicker, and less immediately confusing. This paper describes a system that was developed at UKC to provide a solution to the above problems via the introduction of HTML macros. These macros can be used to provide a standard document layout with a consistent look and feel, as well as tools to ease user navigation. The software is written in Perl, and achieves macro expansion and replacement using the Common Gateway Interface (CGI) and filtering the HTML source. Using macros in your HTML results in your document source code being shorter, more robust, and more powerful. Webs of documents can be built extremely fast and maintenance is made much simpler.

Understanding the role of Digital Commons in the Web; The making of HTML5

The last version of Web́s hypertext standard has been developed from 2004 to 2014. During this era, HTML5 has experienced different crossroads due to the variety of motivations and needs that the main stakeholders interested in its development had. On October 2014, the standard got official by the W3C and closed a period of uncertainty around the future of the Web but at the same time, this agreement also introduced a major change in the own conception of the hypertext́s standard. In this paper we review the current status of digital commons on the Web and the development of HTML5. We also confront this analysis with several semi-structured interviews carried out with different experts in web development that represent at the same time different players of Web́s value chain. We argue that the development of HTML5 represents a new digital commons that prevented the proliferation of proprietary software that took place during the “Web 2.0” period. We claim that the World Wide Web promotes the development of new digital commons due to its own basis as a non-proprietary socio-technological platform. We also conclude that the development of standards and non-proprietary digital technologies is of outmost importance for the future of web business models that are fuelled by major digital players

Word add-in for ontology recognition: semantic enrichment of scientific literature

<p>Abstract</p> <p>Background</p> <p>In the current era of scientific research, efficient communication of information is paramount. As such, the nature of scholarly and scientific communication is changing; cyberinfrastructure is now absolutely necessary and new media are allowing information and knowledge to be more interactive and immediate. One approach to making knowledge more accessible is the addition of machine-readable semantic data to scholarly articles.</p> <p>Results</p> <p>The Word add-in presented here will assist authors in this effort by automatically recognizing and highlighting words or phrases that are likely information-rich, allowing authors to associate semantic data with those words or phrases, and to embed that data in the document as XML. The add-in and source code are publicly available at <url>http://www.codeplex.com/UCSDBioLit</url>.</p> <p>Conclusions</p> <p>The Word add-in for ontology term recognition makes it possible for an author to add semantic data to a document as it is being written and it encodes these data using XML tags that are effectively a standard in life sciences literature. Allowing authors to mark-up their own work will help increase the amount and quality of machine-readable literature metadata.</p
