Below this article on the front page of Cell-therapy.info, you will find three samples of recent news, based on queries or interrogations of data bases with certain parameters or "words". As output one receives the latest news summaries, based on the input string, limited to a certain number of words or full swing (the whole thing). The source of those news "snippets" are normally large news websites like Google, who´s expertise it is to collect the "latest" and "greatest" in News of just about everything and where the customer i.e. myself- your editor Fas- is allowed to define the "content words" of this query himself.
Google is really unique on the web really, which allows one to define multiple parameters. Besides Google I only have found the US government related DB´s supported by the NIH as really good. All other professional news providers- whatever their name (Yahoo for instance) are second rate, since all their queries are pre-defined and most likely not of any use to the savvy user. I have made an exception for the feeds of "Science Daily" and "Medical News Today" where I selected two pre-defined feeds for "Stem Cell News" and "Stem Cell Research News" respectively.
The main thing is- whatever the "selection superiority", key is also the "actuality" of the news i.e it has to be hot and new. As long as it is not a week day, all selected providers will have some news in the selected category ( I assume) which is very current- I will watch that for a few weeks and if not true will change the news sources...
So- what is the technology behind all this ?
