After Wikia, Qwika: the Wiki Search Engine

The last time I wrote about Qwika, it seemed to be a solution in search of a problem. A recent press release suggests that it's managed to come up with an answer to that conundrum: Qwika has turned into a dedicated wiki search engine.

At first sight, you might think that's rather redundant. After all, wikis are essentially just Web pages, and one or two search engine companies seem to have that sector sorted out. But if you only want to look in wikis, and don't want the other million hits on ordinary Web pages that common words throw up, a dedicated wiki search engine makes sense.

Moreover, wikis do have some special characteristics, as Qwika's Luke Metcalfe explained to me:

[W]ikis are quite different to html documents - they have a good amount of metadata associated with them - edit histories, user information, and data embedded within the WikiMedia format. They conform also [to] a certain writing style, which makes things easier to parse from a computational linguistic perspective. Other search engines are only interested in them as html documents with links pointing to them, so they miss out on a lot.

It's early days yet - both for Qwika and the wikis it indexes (1,158 at the time of writing). But recent moves like Wales' Wikia relaunch, which I wrote about the other day, mean that the wiki space is starting to hot up.

So, in the "One to Watch" category, to Wikia, add Qwika.

Searching for an Answer

I have always been fascinated by search engines. Back in March 1995, I wrote a short feature about the new Internet search engines - variously known as spiders, worms and crawlers at the time - that were just starting to come through:

As an example of the scale of the World-Wide Web (and of the task facing Web crawlers), you might take a look at Lycos (named after a spider). It can be found at the URL http://lycos.cs.cmu.edu/. At the time of writing its database knew of a massive 1.75 million URLs.

(1.75 million URLs - imagine it.)

A few months later, I got really excited by a new, even more amazing search engine:

The latest pretender to the title of top Web searcher is called Alta Vista, and comes from the computer manufacturer Digital. It can be found at http://www.altavista.digital.com/, and as usual costs nothing to use. As with all the others, it claims to be the biggest and best and promises direct access to every one of 8 billion words found in over 16 million Web pages.

(16 million pages - will the madness never end?)

My first comment on Google, in November 1998, by contrast, was surprisingly muted:

Google (home page at http://google.stanford.edu/) ranks search result pages on the basis of which pages link to them.

(Google? - it'll never catch on.)

I'd thought that my current interest in search engines was simply a continuation of this story, a historical relict, bolstered by the fact that Google's core services (not some of its mickey-mouse ones like Google Video - call that an interface? - or Google Finance - is this even finished?) really are of central importance to the way I and many people now work online.

But upon arriving at this page on the OA Librarian blog, all became clear. Indeed, the title alone explained why I am still writing about search engines in the context of the opens: "Open access is impossible without findability."

Ah. Of course.

Update: Peter Suber has pointed me to an interesting essay of his looking at the relationship between search engines and open access. Worth reading.
