[BOT] RSS and XFML news feeds

RSS News feeds

The RDF Site Summary format is an XML listing of the latest 'interesting' articles found. It is updated once every few minutes.

most recent 15 items most recent 25 items most recent 100 items

http://drugpolicycentral.com/bot/news/latest.xml (cached RSS 1.0).

The system scans many online papers and news sources daily. Online news sites are crawled continually. You may poll as often as needed.

Atom feeds

most recent 15 items most recent 25 items most recent 100 items

Atom is another XML-based news feed format.

XFML Feeds

Also available are XFML feeds. XFML (eXchangeable Faceted Metadata Language) is a standard markup that can express some of the rich categorization and indexing that bot automatically performs on breaking news.

Javascript

Another way to use our news feeds is to use Javascript. The javascript code snippet below will load up headlines, and print them out separated by linebreaks. Just copy and paste the following into html pages wherever you want to see the headlines. (See the table above for options that apply to javascript news feeds.)
<script language="JavaScript" src="http://drugpolicycentral.com/bot/index.cgi?max=10&merge=1&javascript=1" type="text/javascript"></script> <script language="JavaScript" type="text/javascript"> for (count = 0; count < numItems; count++) { document.write('<P>' + title[count] + '<BR>'); document.write(description[count] + '<BR>'); document.write('(' + date[count] + ' - '); document.write(domain[count] + ')'); document.write('</P>'); } </script>
Available Javascript information for each item:

array name	contents
title	item's title
link	url to item
description	short summary/description of item
date	date system found the item
concepts	list of concepts detected in the item
domain	source domain of item

How the feeds are created

The articles' text is downloaded, categorized, transformed, and summarized. Article text transformation consists of re-formatting, concept detection, classification, and mark-up. News feeds are served on demand. Newsfeeds for searches and for specific concepts are easily created. (Note the RSS link on searches.)

The concept dictionary defines the "concepts" used for the classification and markup process.

Additionally, all site searches are available as RSS, Atom, or XFML feeds.. Simply perform a search; the corresponding XML, XFML, etc. for that search is indicated by a link at the top of the search result page [this search as  ].
