The Semantic Web

A report on the European Commission sponsored Workshop on the Semantic Web has been published on the Diffuse project web site. 12/01/01

Is XML killing the web?

A controversial posting to the XML developers list by John Dvorak claiming that "XML is killing the Web" by introducing many divergent standards, brought many strong reactions, both for and against the sentiments expressed.

Leigh Dodds on XML.com has covered the debate in his XML-Deviant column, "XML Reduced", which questions whether the incessant multiplication of XML standards is leading to confusion, and what is the real minimum a developer needs to know about XML in order to do useful work. See also the XML section on El.pub, for more detail concerning XML. 17/10/00

The Web mapped

Scientists from IBM Research, Compaq Corporate Research Laboratories and AltaVista have completed a comprehensive "map" of the World Wide Web, and uncovered divisive boundaries between regions of the Internet that can make navigation difficult or, in some cases, impossible.

The study, based on analysis of more than 600 million unique pages, found that the World Wide Web is fundamentally divided into four large regions, each containing approximately the same number of pages. The image of the Web that emerged through the research was that of a bowtie.

Four distinct regions make up approximately 90% of the Web (the bow tie), with approximately 10% of the Web completely isolated from the entire bow tie. The "strongly-connected core" (the knot of the bow tie) contains almost one-third of all Web sites.

The authors hope that by using their "Bow Tie Theory", and its new explanation of the structure of Internet, the scientific and business communities will be able to:

The researchers are expecting to update the study on a regular basis. The initial findings were presented simultaneously at the 9th International World Wide Web Conference, Amsterdam (May 15-19, 2000) and at the ACM PODS 2000 Conference, Dallas (May 14-19, 2000).  The "Web Map/Bow Tie Theory" conference paper is should be posted after May 14 at the URL below. 19/05/00

Web engineering

One of the effects of the change from SIGHYPER to SIGWEB is the growth in working groups on different aspects of web architecture and design. Web Engineering (WebE) is concerned with establishment and use of sound scientific, engineering and management principles and disciplined and systematic approaches to the successful development, deployment and maintenance of high quality web-based systems and applications. (Sounds like a sub-set of Information Engineering?)

WebE has a web site and some useful recent resource links on topics like web site testing and quality factors. 24/03/00

Web usability

Web site usability critical

US-based, Modalis Research Technologies has released the findings from an international study examining the 130 "most visited" web sites in the US, Germany, France, Sweden and the UK. Results indicate that site usability ratings are more important than speed or other technical performance measures in generating overall appeal.

The study examined sites by evaluating the user's experience according to seven recognized industry standards (usability components):  intuitive navigation, functional design, efficiency in dealing with different levels of user expertise, minimalist design, robust error management, help and documentation functions, and accurate system feedback to the visitor. Each site's technical performance was also evaluated using measurements of download times, browser compatibility, number of broken links, and number of HTML errors.

Further information about the study is available from the company's web site. 19/12/00

Flash and (non-)usability

Jakob Nielsen's Alertbox for October 29, 2000 contends that although multimedia has its role on the web, current Flash technology tends to discourage usability for three reasons: it makes bad design more likely, it breaks with the web's fundamental interaction style, it consumes resources that would be better spent enhancing a site's core value.

Flash available to 96% of users

An interesting snippet of information included in a Macromedia announcement (dated Ocotober 2000) promoting a number of new extensions to the Dreamweaver web page editor - that the Flash Player is now installed on 96 percent of web desktops. The figure is based on a Macromedia study carried out by NPD Online Research, the parent company of Media Metrix.

URL: http://www.useit.com/alertbox/20001029.html

Flash usability addressed

As a possible response to concerns expressed by experts as to the usability of Flash on the web, Macromedia has launched a "usability initiative". A new usability area on the Macromedia web site contains usability suggestions, accessibility information, examples, articles and white papers aimed at developers using Flash "to deliver better user experiences".

A Flash Accessibility Kit to assist developers in making their content accessible to people with disabilities is also available, offering publishing templates for Flash authoring as well as strategies to provide alternative text and aid navigation within Macromedia Flash content. 12/12/00

"Compendium of HTML Elements"

The latest release of the "Compendium of HTML Elements" (Revision 8.1) examines 160 HTML tags, 264 attributes, 271 arguments and an extensive listing of HTML scripting events.

The information is presented in several ways: "from 6 browser manufacturer's documentation (by version); from reader's testing 28 different browsers/versions on 11 operating systems; and, from our own experiments and coding notes". 08/08/00

"Semiotic" web design

Academics from Luton University and Herts University (plus industrial partners) have formed a new mailbase discussion list. The focus is the design of E-commerce sites and other HCI components from a "semiotic" viewpoint. This view is encapsulated in "SMDF" (Shared Meanings Design Framework)  - a new methodology which aims to help design sites which are culturally neutral, which only transmit intended meanings of trust and security.

The partners believe that it offers an alternative perspective to that of Jakob Nielsen (see web link below) as semiotics views an interface as a complex "sign system" which is interpreted differentially according to , for example, culture. The group do not believe, for example, that one can simply validate a trans-national e-commerce site using just five users (as Nielsen suggests), and feel that cross cultural issues require a more rigorous treatment. Contributions to the discussions are being welcomed.

Semiotics is defined in the dictionary as: "the study of signs and symbols, especially the relations between written or spoken signs and their referents in the physical world or the world of ideas". 31/03/00

Jakob Nielsen - web usability column

Jakob Nielsen, the usability guru, produces a monthly column on web design that is definitely worth a visit. Recently he has taken the view that not sufficient emphasis is given to ensuring speedy display - it is no use having fancy graphics if the viewer clicks off to another site before the graphics have time to appear.

In an Adobe Web Centre interview, designer Val Casey said "I think that usability is dead. That's really extreme to say, but I don't think my users are dumb. Even the most novice user has some sort of consciousness about the way a computer works, even from watching television. The same sorts of styles are shared, so now we've got a visual language that crosses over and people are getting used to it."

Importance of content

It is as if the importance of content to publishing was forgotten in rush for companies to get web sites on-line. Increasing coverage of the role content has to play on the web, should help in someway to redress the current imbalance - of highly articulated web sites which in many cases have little "to say".

In it's Back to Basics series, the on-line magazine "Web Review" champions the importance of content on the web in an article entitled: "The New Web Strategy: Content is the Cornerstone". The article provides a check list, if one were needed, of key requirements when defining the purpose of a web site and planning the content to reflect these. The article is written by Amy Gahran the publisher of "Contentious", an interesting web-zine about content development for online media.

Hoffman and Novak define flow as: "the state occurring during network navigation which is:1) characterized by a seamless sequence of responses facilitated by machine interactivity, 2) intrinsically enjoyable, 3) accompanied by a loss of self-consciousness, and 4) self-reinforcing." To experience flow while engaged in an activity, consumers must perceive a balance between their skills and the challenges of the activity, and both their skills and challenges must be above a critical threshold. Their paper "Modeling the Structure of the Flow Experience Among web Users" is available at the University of Vanderbilt web site.

Human effects of the Internet

HomeNet, a Carnegie Mellon research project studying what people do with the Internet and how it affects their lives has published a report which poses the question: "Internet paradox: A social technology that reduces social involvement and psychological well-being?"

The research examined the social and psychological impact of the Internet on 169 people in 73 households during their first one to two years on-line. It showed that, greater use of the Internet was associated with declines in participants’ communication with family members in the household, declines in the size of their social circle, and increases in their depression and loneliness. Such findings could have implications for research, for public policy, and for the design of technology. A full list of research reports, including this one are published on the web.

Navigation in web applications

The emergence of the web as a new application delivery platform through the development of sophisticated web-based Java applets, has significant impact on the page-based navigation currently used on the web. As sites become more interactive navigating between applet views will become increasingly commonplace. A paper entitled: "Navigation in web Applications" provides a view on how to reduce user confusion in such environments.

Metadata theory

There is a very large body of knowledge on the subject of metadata, much of which pre-dates the development of information webs. Metadata is essentially data about data, an example being the card index catalogue in a library; where the information on that card is metadata about a particular publication. The application of solutions based on metadata may solve many of the problems associated with content identification and delivery on information webs. It is from the standpoint of: "metadata being used by anyone to make their material more accessible", that much of the relevant research is based.

Further information on Metadata theory is available on the Metadata topic page.

Using metacontent to promote relevance

The free e-zine WebPromote Monthly looks at the issue of web site promotion and in the July 1997 issue considers the effectiveness of meta tags in improving web pages' "relevancy ranking" when indexed by search engines. It includes tips on how to write metacontent tailored for spider-based search engines. Further information on meta tags and their relevance to site promotion is also available in the January, May, and June 1997 issues.

Typography and fonts

Dynamic fonts

Until the arrival of dynamic fonts, web page designers have been limited to using a few common fonts simply because typefaces in web documents cannot be viewed unless the same typefaces are installed on the end-user's system.

This font fidelity problem can be solved by making the fonts in HTML documents portable, as has been achieved by Bitstream's TrueDoc. The company claim TrueDoc supports all font formats (including existing TrueType and PostScript Type 1 formats), all Unicode standards, as well as non-Latin typefaces such as Arabic, Chinese, Japanese (Kanji), and Korean. Several leading web software developers and tools vendors support this example of dynamic font technology, including Netscape's Communicator client and Microsoft's Internet Explorer along with product releases from SoftQuad and Corel.

Colour and the web

Victor Engel's Home Page, has some of the best explanations and demonstrations of the Netscape colour palette and how it influences the look of colour on the web.

In a bid to untangle the mess surrounding colour palettes and the web, Pantone has developed a system, which if implemented could see the extension of its colour matching system to the online world. The Pantone system is widely accepted and has been utilised by designers and printers in the print media since 1963.

The Pantone Internet Color System (a module in its ColorDrive web Tools for Windows) includes a library, of 216 "Internet -safe" colours, that the company claim, "appear exactly as specified across computer platforms, regardless of monitor resolution". The ICC profiles are embedded within JPEG and TIFF graphic files, whilst a browser plug-in for Netscape Navigator and Microsoft's Internet Explorer, (available free-of-charge from Pantone's web site), enables anyone browsing the web to automatically display these images, regardless of platform, colour-corrected for each individual's monitor.

ColorDrive supports many leading design applications, including CorelDRAW!, Adobe Photoshop, PageMaker and Illustrator, QuarkXPress, Macromedia FreeHand, Fractal Design Painter, Deneba Canvas and Micrografx Designer. Details concerning the system and copies of the browser plug-ins are available from the Pantone web site.

There is a site dedicated to colour managment site for ColorSync 2 under MacOS.

The web colour test site shows text in one colour on a background of another - all standard web colours can be easily viewed in this form.

Getting the colour right

Most people know that pictures developed on a Mac look darker on a PC and vice versa. This type of problem is a worry for games publishers and, increasingly, for e-commerce sites. One of the leading producers of tools to overcome colour matching problems is Sonnetech who have a variety of tools for different applications. Many games producers are incorporating 3deep software into their products. The web site has a lots of technical info on colour problems and links to other colour sites.

Browsing screen resolution increases

WebSideStory's StatMarket has reported that there seems to be a steady migration to higher screen resolutions by Internet users. The finding has important implications for web site designers who currently tend to design for the, "lowest common denominator", 640x480 pixel resolution.

This information, available at StatMarket.com, is based on data gathered in real time from more than 34,000,000 daily visitors to web sites using WebSideStory's HitBOX web traffic analysis technology. The numbers published to substantiate the claim reveal that:

RealNames Corp. has launched a service to enable web sites to use 'real names' instead of URLs. The service will cross-reference names chosen by subscribers to web pages and users will be able to enter the name in their browser or search engine instead of the URL. Some search engines already allow keywords instead of URLs and RealNames has signed an agreement with Microsoft for the system to be incorporated in IE5 in the future. Users can also download a software patch to enable the names to be used with their existing browsers. It costs $100 per year to register a name, but the terms and conditions are rather strong, for example RealNames only undertakes to accept 2500 name connections a month before additional charging comes into force.

IDC report on web application development

An IDC study of web developers and how they work is available on the web. The study set out to answer the question: "What is the state of Web application development today?" IDC e-mailed invitations to roughly 14,000 people who were thought to be web developers to fill in a web based survey questionnaire. 800 visited the site and 519 filled in the questionnaire. The report considers why businesses are moving to the web, what applications are being developed and what the developers want.

Web sites and gender

A recently launched web site, targeting girls between 5 and 10 years of age, claims that pre-launch research highlighted girls not as "techno phobes" but as "content critics". The developers believe that whilst there are "literally hundreds of web sites overflowing with "zap" and "action" for boys, there is very little going on specifically for girls, especially when it comes to interactivity".

The site, MY LEGO SCALA PLANET, claims it focuses on "girls' most important values - story telling, strong characters and creative expression". This news item highlights a valid concern over the effects of digital technology on children's development, and in particular the role that gender plays in the receptiveness of individuals to particular styles of multimedia.

Commercial and academic website design

Research carried out at the University of Applied Sciences, Wiesbaden, Germany under the Empirical Web Analysis (EWA) project has investigated the discrepancies between commercial and academic websites. The project confirmed striking differences between the approaches of the two sectors to web design. A summary of the report has been published in English whilst the full version is published in German.

In general the research confirmed that the use of images, image maps, forms and server side programming (eg. Java) were far higher on the commercial sites. The most marked difference between the two types of site was demonstrated by the use of cookies - nearly 33% of the commercial sites used them whilst only just over 1% of academic sites did so.

In-line with the common perception that academic sites play a leading role in communication, the researchers found that the educational sites embedded far higher numbers of mail and ftp addresses in their pages than did commercial sites. A number of reports, in German, written by the head of the EWA research effort, Volker Turau are also published on the web.

electronic commerce, general demographics, technology demographics, data privacy, web and Internet usage, Software Filters and Content Rating, Internet shopping, Internet banking, Beliefs About Society, cultural issues and webmasters.

Key survey results showed: a continuing growth of female Internet users; browser switching with a growth in Microsoft market share; only 4% of users connect with 14.4Kbs modems or slower.

Browser war ends....

Zona Research has released its final browser study, which tracks browsers used in the US corporate environment. When Zona's browser study was first conducted in January 1996, there were nine companies fighting for a market estimated at the time as being worth US$ 200 million dollars. Now, almost four years later, two have emerged as the dominant players for what Zona term "a zero dollar market".

In their final browser study Zona reports that Microsoft's Internet Explorer was the primary browser choice for 64% of the responding organisations while 36% of the respondents indicated Netscape's Navigator.

Web sites fail to provide "customer service"

Forty-two percent of the top-ranked web sites either took longer than five days to reply to customer e-mail enquiries, never replied, or were not accessible by e-mail according to a report issued today by Jupiter Communications.

The report, from Jupiter's Strategic Planning Services (SPS) clients, focused on 125 sites in five categories: content, consumer brands, travel, retail, and financial services. Most retail shopping sites performed the best, with 54 percent responding in less than one day. However, in some segments there is ample room for improvement. For example, 19 percent of the travel sites tested took at least three days or never responded to Jupiter's enquiries.

In order to respond in a timely manner the report recommends that sites develop or utilise some form of "auto-acknowledge" feature that responds to all incoming requests stating that the question was received and estimates a time frame for how long it will take to respond to the question. The report also recommends that sites continue to focus on building ongoing communication with users. Reassuring customers that a transaction is proceeding as planned and giving users multiple opportunities to access context-sensitive support options will help to eliminate user demand for support.

Web search engines compared

SearchEngineWatch provides reviews and resources on web search engines, publishing the e-zine, Search Engine Report. Of particular interest are the notes concerning how different commercial web search engines index web pages - giving suggestions as to how best to design websites to take advantage. For a comprehensive list of commercial search software, see the Products page on this site.

An interesting comparison of web search engines has been published. It makes the assertion that all of the well-known web search engines other than Lycos use word proximity matching.

Search engines - confused?

The edition dated November 3, 2000 focusses on the subject of paid listings which are changing the search engine landscape "rapidly". A particular form is called "paid inclusion", apparently now in place at Ask Jeeves, LookSmart and Inktomi, and which is highly likely to improve a sites visibility. The articles differentiate between terms such as "inclusion" and "placement", providing excellent tips as to how these latest developments in the commercialisation of the web are likely to impact the "visibility" of sites via the most popular indexes. 14/11/00

"Invisible web" revealed

The Search Engine Report of July 6, 1999 ran a brief article entitled: "The Invisible Web Revealed" which highlights how to search for resources on the web that are currently "locked away" in databases. Such information is usually invisible to search engines and the article explains how such resources may be made more "visible" and hence accessible. The article gives links to some initial "catalogues" of such databases.

Souped-up search engines

Declan Butler, the European Correspondent of Nature thought readers of El.pub might be interested in a news and features article entitled, "Souped-up search engines" he has published in Nature recently.

For scientists, finding the information they want on the World Wide Web is a hit-and-miss affair. But, as the author reports, more sophisticated and specialised search technologies are promising to change all that. The article is freely accessible at the URL below. 16/05/00

Info. access on the web limited and unequal

An NEC Research Institute study analyses the accessibility and distribution of information on the web. The study, which appeared in the July 8, 1999 issue of the journal Nature, concluded that search engines do not index sites equally, may not index new pages for months, and no engine indexes more than about 16% of the web. The study findings indicate:

The report goes on to comment that the web is transforming society, and that search engines are an important part of the process. Consumers use search engines daily to locate and buy goods or to research many decisions (such as choosing a vacation destination, medical treatment or election vote). As the web becomes a major communications medium, the data on it must be made more accessible.

Search engine indexing and ranking may have economic, social, political, and scientific effects. For example, indexing and ranking of online stores can substantially effect economic viability; delayed indexing of scientific research can lead to the duplication of work; and delayed or biased indexing may affect social or political decisions. One of the great promises of the web is to equalize access to information.

With the web fast becoming the major communications medium, attention should be paid to the accessibility of information on the web, in order to minimise unequal access to information, and maximise the benefits of the web for society.

Search engines and web site visitors

The Web Site Journal, a free e-zine concentrating on matters relating to running web sites, provided some statistics concerning the top referring protocols of visitors to their site: Web Page (links) 49.52%; Search Engine 4.95%; Web Mail (eg. Netscape Webmail, Hotmail) 0.12%; Email Client (eg. Outlook, Lotus Notes) 0.11%; News Group 0.04%; Unknown 45.26%.

No details were given concerning the parameters of the research and so the results can only be viewed as circumstantial - but the figures were used to challenge the often held view of the importance of web search engines in driving visits to web sites.

Web advertising

There are a number of commercial products which automate placing and maintaining banner ads on websites. More recent software claims to enable targeted advertising based on the notion of "understanding" a visitor's requirements (for a selection of these see the section on website advertising on the products page on this site).

There are also many programs providing web log analysis from which web masters hope to glean an appreciation of their visitors requirements. However most of the methods employed by these products have been developed independently and from a potential advertisers perspective can seem to be unregulated/unverifiable. The Audit Bureau of Circulations (ABC) runs a website which publishes independent audits of the activity on the websites of its members. ABC circulation figures are one of the quantitative measures used by purchasers of advertising in the print media to assess the suitability of periodicals' readership for the advertising message.

The ABC wish to extend their quantitative approach to online media. For details of the the ABC Interactive's role and methodology see their website. There are also commercial companies offering similar services, see the website analysis section on the products page.

W3C Accessibility QuickTips

The Web Accessibility Initiative has as a mission: "the W3C's commitment to lead the web to its full potential includes promoting a high degree of usability for people with disabilities". The Web Accessibility Initiative (WAI), in coordination with organisations around the world, is pursuing accessibility of the web through five primary areas of work: technology, guidelines, tools, education and outreach, and research & development. WAI have recently published a number of guidelines for web publishers including page author guidelines and a quicktips page.

The "Web Content Accessibility Guidelines 1.0" have W3C Recommendation status. Each guideline has associated "checkpoints" explaining how these accessibility principles apply to specific features of sites. Specifics on how to implement the checkpoints with the latest versions of mark-up or presentation languages such as HTML, CSS (Cascading Style Sheets), or SMIL (Synchronized Multimedia Integration Language) are described in a parallel "Techniques" document, to be updated periodically.

Authoring Tool Accessibility Guidelines

The W3C has released the "Authoring Tool Accessibility Guidelines 1.0" (ATAG 1.0) specification, as a Recommendation. The specification provides guidance as to how developers of authoring tools, such as HTML editors and site management tools, can encourage and assist in the production of accessible web content through prompts, alerts, checking, repair functions, and help files in their tools.

In addition to their value to accessibility, many of the principles addressed in the specification, such as the importance of producing and preserving valid markup, promote interoperability of the web in general. According to the W3C, ATAG 1.0 addresses a broad range of tools, including WYSIWYG editors, "save-as-HTML" conversion tools, tools that dynamically generate content from databases, formatting tools, image editors, and site management tools. 08/02/00
