Evaluating Web Sites:

Type of Content:

The website I have chosen is a site that contains an article located at O’ReillyXML.com. This is a media website that publishes articles and resource material. The information is more reliable than a site such as a blog but not as proven as a research paper. This site however, reproduces topical articles from many newspapers and magazines.

Search Engine: Yahoo “Semantic Web”

The description of this article, although brief, has more credence because of the website that it appears in i.e. “Semantic Web Resource Center”. This site is a collection of commercial and public resources for research groups and has a catalogue of articles on the Semantic Web.

The headline of this article is: “A Relational View of the Semantic Web”.

The “blurb” reads “Creating a Web of machine readable information, leading the Web to its fullest potential…” But this is an introduction for a list of articles about the Semantic Web and not directly attributable to this article.

Summary: “A Relational View of the Semantic Web:”

Abstract:

Software which falls into the category of “Web 2” have the ability to search and find information drawn from databases using applications that are designed to search all data, locate and identify combinations in which bits of data appear and interpret the relevance of the data for the user. This new software has a flexibility that does not need to conform to rigid database design features to conduct a search. The outcome is the integration of data in any database being available and accessible to the user. Therefore, creating the most suitable software to operate within the semantic web and produce these results is the goal of numerous software developers.

Relevance to Purpose:

I selected this article for its relevance to the concept of Meta Data being the data required to produce quality search results in research. The concept of the Semantic Web is an evolutionary step to using Meta Data and the title implies that the relational aspect between types of Meta Data is an important factor it the development of the Semantic Web.

Purpose of the Site:

This site would be described as commercial because it invites subscription to its service for a fee and has an abundance of advertising material on it. It sells books on line and reference material can be downloaded for a fee. However, the article is valid and the information can be tracked to a reliable source.


O’RiellyXML.com is a resource and publishing center. To post to the site membership is required but articles are free to read. It would be a useful search tool for future reference.

Author:

The Journalists who wrote this article are recorded in the search results. The facts noted in their article are suitably referenced in the Bibliography for authenticity. The credentials of the author are available on a separate reference page:


Andrew Newman

“Andrew Newman is currently working for the University of Queensland's eResearch centre and part time on his Honours. His has previously worked on Kowari and continues to actively support the RDF API for Java, JRDF. His current interests include SPARQL, defeasible logic, agile databases using RDF, ontology development, and software development methodologies. and as the source is a newspaper, it should be seen as an opinion on a topical issue and not a research document.”

Publisher:

The article is published by “© 2008, O'Reilly Media, Inc.”. The Website produces a directory of articles about the topic but states at the foot of the page that copyright is owned by the individual authors. There is an invitation on the site to submit articles on topics that are new and “it helps if you know that we tend to publish "high end" books rather than books for dummies, and generally don't want yet another book on a topic that's already well covered.”

Content Bias/Balance:

The content of articles is talking about a new area of Web use in the Semantic Web. The article doesn’t lend itself to being bias unless support for the Semantic Web concept is bias. There is a substantial amount of information and speculation that is supported by explanatory data and a bibliography.

Coverage:

Other articles about the topic are published on the same site and are listed in the directory. Also using Google I found 27 related sites:

Currency:

The date of the article was recorded on the search results. The development of this concept will make each article time sensitive because of the changing technology. However, this site seems to be a popular resource for publications and attracts current information on the topic. A search of this site on the Semantic Web produced 9,842 references to similar articles. The range of posting dates appears to be from 2000 to 2008 but they are not listed in date order and required a manual search for the information.

Signs of Recognition:


Links to http://www.xml.com/semweb/ (above) – 6 (3 are blogs, 2 are linked to the publisher’s Webpage and 1 is an educational reference.

Tags for this Site:


Tags for www.xml.com (above) – 13 bookmarked items from this site used by 5,585 people. Is this a significant number of tags for this type of site? A search in del.icio.us for “Semantic Web” resulted in 23,915 bookmarked items by thousands of people. This doesn’t place www.xml.com as a popular website for this information.

Blog reaction to website www.xml.com 1,432 The “authority rating” is respectable for the blogs on a specialized topic. A search for blogs with references to the “semantic web” was 8,281. Not all references from xml.com are about the semantic web so more comparison would have to be made to determine whether bloggers thought this site is popular.


Blog reaction to website www.xml.com 1,432 The “authority rating” is similar for these blogs as the previous but would need some more comparison with other sites to get the relative popularity.

Citations of Articles by other Researchers: This is a search using the title of the article to see whether it has been cited in any research articles. The search found that the article had been cited in one published paper.
