Alexa Web Information Service (AIWS)

July 13, 2008 2 comments

The Alexa Web Information Service (AWIS) makes Alexa Internet’s data on Web sites available to researchers and website developers. The various operations offered as a part of AWIS include

o    URL Information,

o    Web Search,

o    Browse Category,

o    Crawl Meta Data.

The Alexa Web Information Service makes Alexa’s vast repository of information about the traffic and structure of the web available to developers.

Service Highlights

  • Gather information about web sites, including traffic data, contact information, related links and more.
  • Access historical traffic data for web sites to analyze growth and understand the effects of specific events on web site traffic
  • Build a web directory into your web site or service using an Alexa enhanced DMOZ-based browse service
  • Access the list of sites linking to any given site

Detailed Description

AWIS provides the following operations, or “actions”:

URL Information

·         The URL Information action gives developers direct access to information pertaining to web pages and sites on the web that Alexa Internet has gathered through its extensive web crawl and web usage analysis. Examples of information that can be accessed are site popularity, related sites, detailed usage/traffic stats, supported character-set/locales, and site contact information. This is most of the data that can be found on the Alexa web site and in the Alexa toolbar, plus additional information that is being made available for the first time with this release.

Historical Traffic

·         The Historical Traffic action gives programmatic access to web site traffic rank, reach, and page views going back five years. Use this action to compare a web site’s popularity over time, identify trends, or display graphs of traffic.

Sites Linking In

·         The Sites Linking In action returns the sites linking to a specified web site.

Browse Category

·         The Browse Category action allows developers to access all of the information available at the Open Directory without the need to download or host the directory database on their own systems. This service returns web pages and sub-categories within a specified category. The returned URLs are filtered through the Alexa traffic data and then ordered by popularity.

Crawl Meta Data

·         The Crawl Meta Data action gives developers access to metadata collected in Alexa’s Web Crawl. For example, a developer can get pages size, checksum, total links, link text, images, frames, and any Javascript-embedded URLs for any page in the crawl.

The electronic Journals Delivery Service (eJDS) is a prototype programme geared to facilitate the access to current scientific literature free of cost in the fields of Physics and Mathematics. The goal is to distribute individual scientific articles via e-mail to scientists in institutions in Developing Countries who do not have access to sufficient bandwidth to download material from the Internet in a timely manner and/or cannot afford the connection. Providing scientists with current literature supports their ongoing research.This service is provided by Science Dissemination Unit of the Abdus Salam International Centre for Theoretical Physics (ICTP).

Accessing to the electronic journals with eJDS is very easy, you just need to:

  1. register to the service: you need to apply by sending an application form by fax or mail. You will then be informed by e-mail on how to proceed.
  2. use the service: once you successfully registered, you can search scientific articles either using e-mail or using the web.

The eJDS was made possible through agreements with several important scientific publishing companies and societies who provide access to their journals for free in the fields of Physics and Mathematics. These agreements are handled by the ICTP Library.

Copyright should be the same for digital media, say UK researchers

July 3, 2008 Leave a comment

UK researchers want to be able to copy parts of electronic materials for non-commercial research in the same way that they can with print, according to a new study.

In a recent British Library Intellectual Property survey, 93 per cent of UK researchers agreed that anyone involved in non-commercial research should be allowed to copy parts of electronically-published works such as online articles, news broadcasts, film or sound recordings.

In addition, 87 per cent of respondents said they should be able to use exceptions with digital media. Exceptions to intellectual property rights for print media include archiving and news-reporting rights and education exceptions. Particularly important for many academic researchers is the fair-dealing exception. This allows copies to be made from in-copyright work without permission from, or payment to, the rights holder provided that it is for non-commercial research, private study, criticism, review or news reporting.

In the survey, 68 per cent of the respondents said that the fair-dealing laws should be the same whether the material is in paper or in electronic format. This is not the case for electronic media today, according to Ben White, intellectual property manager at the British Library. ‘In the digital world, databases, journals and books aren’t covered by copyright but by contracts,’ he explained. ‘Copyright has been agreed over many years as a careful balance between the needs of the rights holders and those of the users but contracts are really about the rights of the rights holders.’

White and his colleagues at the British Library have analysed many publisher contracts for digital information. They have found that more than 90 per cent of them do not permit users to do as much with the information as they would be allowed to do with print publications under copyright laws.

White believes that it is important to tackle this issue now. ‘By 2020 we estimate that 80 per cent of information will be available digitally and 20 per cent of the information will only be available digitally,’ he pointed out. ‘A lot of money is being spent on e-resources but the contracts are more restrictive.’

What’s more, the details of the contracts differ greatly between publishers. ‘Some are more restrictive and some are less restrictive – we found one contract that doesn’t even allow users to print out material,’ said White. Such a situation makes life very difficult for both libraries and users. ‘The British Library collections grow at 15 km per year and have a lot of digital objects within them. We can’t have different usage conditions on an object-by-object basis otherwise the users of our reading rooms would have to be intellectual property lawyers,’ he pointed out.

This new survey forms part of the British Library’s response to a recent UK Intellectual Property Office consultation. ‘We are arguing that the exceptions shouldn’t be overruled by contract law,’ said White. ‘We are asking for clarity.’

Such provision for digital information use has already been implemented in other European countries such as Ireland, Portugal and Belgium. In addition, the Development Agenda of the World Intellectual Property Organization, being led by Chile and three other Latin American countries, is pushing for minimum exceptions such as for education to become part of international law for intellectual property.
