Online Database: BASE (Bielefeld Academic Search Engine) Passes 25 Million Records

From an Email:

+ More than 25 million records from more than 1.720 repositories worldwide

+ About 3 million records this year or about 14.200 records per day, while the number of repositories increased in 2010 about 22 % until now

+ More and more journals deliver content via OAI-PMH (especially journals using OJS), which is another evidence for the growing importance of open access in scholarly communication

From the BASE Web Site:

BASE is one of the world's most voluminous search engines especially for academic open access web resources. BASE is operated by Bielefeld University Library.

As the open access movement grows and prospers, more and more repository servers come into being which use the "Open Archives Initiative Protocol for Metadata Harvesting" (OAI-PMH) for providing their contents. BASE collects, normalises, and indexes these data.

In comparison to commercial search engines, BASE is charcterised by the following features:

+ Intellectually selected resources

+ Only document servers that comply with the specific requirements of academic quality and relevance are included

+ A data resources inventory provides transparency in the searches

+ Discloses web resources of the "Deep Web", which are ignored by commercial search engines or get lost in the vast quantity of hits.

+ The display of search results includes precise bibliographic data

+ Several options for sorting the result list

+ "Refine your search result" options (authors, subject headings, year, resources and language)

Thursday, 24th May 2012

Recently I have found myself cooing over visualisation maps (and heat maps) of health and well being resources. The content rich data is overlayed with mapping technologies, and some interesting themes and patterns are emerging.


Click to view the article The fallacy of information overload
Wednesday, 23rd May 2012

A lot of the talk around social media in the last year has been around information overload. Social media has provided us with new and exciting ways to create content. But it has also meant learning new ways to manage and engage with social media tools. Are we teetering on the edge of an information overload precipice?


Click to view the article Information overload: fact, fantasy or filter failure?
Wednesday, 23rd May 2012

Information overload is a figment of your imagination. Or a failure of your filter. Or a symptom of your technological submissiveness. Depends on who you ask.


Click to view the article Newsdesk: tracking millions of pieces of information a day
Tuesday, 22nd May 2012

What if you had to sort through 3.5 million articles and social media posts a day and try to pull out the most relevant items for your organisation? What if you then had to cobble it all together into something readable for your top groups and executives in your organisation?
