The Prowess of GahooYoogle

I was quite surprised when information scientist
Amanda Spinks told us at a talk that search engines usually have a 5% overlap in terms of hits. What this means is that searching is an art more than anything else -- what we come up with really depends on the tools, techniques, experience, and expertise of the searcher. (And dare I say, a certain element of luck, too).

Take a look at GahooYoogle, a nifty search engine which allows us to see results of both search engines, side-by-side. Does this make searching easier? Not really. In my opinion, if you want to do that, then go for a meta-search engine. But if you want to see how the magic of the Google algorithm works compared to another "normal" search engine which uses keyword searching, then try this out.

Do you notice something? One can simply type in the article's full title (or even parts of it, provided it's wrapped around with "quotations"), and wham! there you go, the first few hits will usually lead you to the full or abstract, whereas in a search engine such as Yahoo!, you'll have to work a lot harder to find what you're looking for.

Ah yes, what can't Google do? Another reason why it's still the information professional's best friend.

The Myth of Caduceus?



A majority of medical organizations employ a symbol of a short rod entwined by two snakes and topped by a pair of wings. Known as the "caduceus" or magic wand of the Greek god Hermes, conductor of the dead and protector of merchants and thieves, the caduceus came to be associated with a precursor of medicine, based on the Hermetic astrological principles of using the planets and stars to heal the sick in the 7th century.

However, recent medical observers and physicians have been critical of the symbol, for Hermes also happens to be the god that leads the dead to the underworld and is not only associated with wealth and commerce, but happens to be the patron of thieves (a larcenous figure in Greek mythology). Some medical purists suggest we should go back to the staff of Aesculapius, which is depicted as a single serpent coiled around a cypress branch.

In 2003, Wilcox and Whitham further ignited controversy in the medical community when they published an article in the Annals of Internal Medicine, arguing that the design is derived not from the ancient caduceus of Hermes but from the printer’s mark of a popular 19th-century medical publisher. Because of this mishap, the modern caduceus became a popular medical symbol only after its adoption by the U.S. Army Medical Corps at the beginning of the 20th century. The authors contend that a misunderstanding of ancient mythology and iconography has led to the inappropriate popularization of the modern caduceus as a medical symbol. As they argue, the Asklepian is a medical symbol with a heritage stretching well over two millennia while the modern caduceus became a popular medical symbol only in the early years of the 20th century. Scandalous, you say?

A Wiki’s Worst Nightmare

Recently, the Health Library wiki team discussed the implications of creating a wiki for the health sciences. Is it useful? Who will use it? Why? How? While we were all excited of the implications of what we were doing, we were really walking on unchartered waters. Either we are stumbling onto something great, or we are wasting our time experimenting with something that's not going to be used other than the few people whom we send out the link to.

One question that we debated about was how to monitor the postings. As Stephen Colbert's now infamous Wikiality monologue reveals, not everyone appreciates the power of wiki. Not everyone will have the faith of a democratic wiki. According to Wikipedia, astroturfing:
consist[s] of a few people discreetly posing as mass numbers of activists advocating a specific cause. Supporters or employees will manipulate the degree of interest through letters to the editor, e-mails, blog posts, crossposts, trackbacks, etc. They are instructed on what to say, how to say it, where to send it, and how to make it appear that their indignation, appreciation, joy, or hate is entirely spontaneous and independent; thus being "real" emotions and concerns rather than the product of an orchestrated campaign.

There have been cases reported of astroturfing. It's a serious matter, particularly for a Health Libray Wiki which relies on both updated and accurate information. It should be taken into consideration, particularly if there are a few unruly who want to leave a legacy by giving false information to hurt the many. Can a few wiki masters constantly monitor such a wide net? That will be a challenge that we will face as we move into the information grassroots democracy. With open access, open collaboration, open authoring, open platforming, and open searching in Web 2.0 comes hurdles which we have to face bravely and heads-on.

Microsoft and/or Google? Competitors? Or Just Neighbours?



A fascinating but rather dated article caught my attention as I was taking my daily dip into the blogosphere. It brings up an interesting debate that continues to rule the realms of both the corporate and information world: is Google taking over Microsoft's reign? Or are they even competitors in the first place?

According to Why Microsoft can’t best Google, the answer is yes, Google will rule the day (which is tomorrow). Here is why Phil Wainewright thinks so:

(1) Microsoft wants everyone to have a rich desktop experience, Google wants everyone to have a rich Internet experience.
(2) Microsoft's business model depends on everyone upgrading their computing environment every two to three years. Google's depends on everyone exploring what's new in their computing environment every day.
(3) Microsoft looks at the world from a perspective of desktop+Internet. Google looks at the world from a perspective of Internet+any device.
(4) Microsoft wants computers to help individuals do more unaided. Google wants computers to help individuals do more in collaboration. In the Internet age, who wants to work alone any more, when all the unexplored opportunity is in collaborative endeavor?
(5) In a few year's time, who's going to still be working at a desk anyway?

The most interesting food for thought comes from the blog comments. Take a look. Apparently, the reactions are mixed; not everyone thinks that Google and MSN are competitors. One commentator argued that it's comparing "apples to icebergs." In my opinion, Google is certainly moving into MSN's dominance and in many ways (but not all), has surpassed it. However, one piece of technology which has never taken off has been Googletalk, which is supposed to be the rival to MSN Messenger. On the other hand, Gmail is slowly but surely equalling MSN Hotmail in terms of popularity (and definitely ease of use). Time will tell who will win, or whether winning is the end goal...

A Good Blog

To be good at something, one should always look to the best. And recently, one medical librarian's blog that has caught my attention is the Krafty Librarian. Just when I thought I had stumbled onto sliced bread, it turns out that someone has already gone on to desserts. Such is life... The Krafty Librarian focuses mainly on cutting edge issues about technology - and recently she has turned her focus of attention towards mashups. She has scoured the internet looking for mashup applications, particularly those with a health sciences library-related focus.

I'm anxiously anticipating her upcoming blog entry, as she has promised to write about mashups and their potential applications impact in the health sciences. The Krafty Librarian's most recent entry introduces us to Library Elf - a personal library reminder service that lets create their own username and password then they select their library and then they give Library Elf their library card number and pin number. If the patron's library is not listed they can recommend it to Library Elf to have it listed. Thus, the users then can receive emails, text messages, and RSS feeds for renewal reminders, overdues, and hold items at one click of the mouse (or a few). What do you think? Is it viable?

It's this sort of "mashing" up of different programs and applications through API that makes the future of online technology that much more intriguing.
