Adaptive Path have taken things pretty far with their new initiative for designing the new browsing experience for the users of tomorrow. Aurora is indeed a magnicent site on the web horizon. The whole thing is still just a concept, being developed in association with Mozilla Labs, but the video they released, the first in a series dealing with Aurora, is quite an interesting vision of the future. The movie “Johnny Mnemonic” comes to mind, when Keanu Reeves searches for the sent fax from Japan, on a VR terminal in a computer shop in New York (okay, I like SciFi, what can I do).

Basically, Aurora allows for a browsing experience where information is organized according to time and usage. The less you use something or the older it is, the farther “downwards” it lives on the Z axis (perpendicular to screen). The words “out of sight, out of mind” truly have a literal meaning here. The interface looks very interesting, and I especially like the little touch device in the end, which helps you take the information you need or like with you.

Anyway, here’s the video:

Key components of Aurora project (from official site):

- Natural interaction: Spatial, visual, and physical engagement with the Web
- Continuity: Seamless, consistent Web and browser experience across devices
- Multi-user applications: The Web as a space for collaboration, sharing, and remixing
- Context awareness: Products that know where you are and what you’re doing, both physically and virtually

Who knows what it will eventually be like, when the time comes to introduce it as a product, but so far it’s looking very interesting.

Cuil has been live (or down apparently) for days now. While I immediately formed an opinion about the interface and result presentation, I wanted to keep using it for my own day-to-day searches in order to get a more complete picture about its search value.

Basically, I expected a lot more from all the information I read about it prior to launch. The results are presented in a grid, which would be ok (easier to scan results) except that the grid is actually a set of columns which resemble a newspaper page much more than an organized set of information. Since grid blocks are not the same size, quick scanning is more difficult, as you have to scroll up and down to see the titles and descriptions. Furthermore, since the results are organized in two dimensions, the usual linear approach of ranking results is absent, so I expect users to have a little trouble determining which result is deemed more relevant compared to others, although this is not necessarily bad.

That aside, they kept the right margin space for advertising options, which aren’t there and probably won’t be for a while. This I think was a bit too quick. Why not offer more results on the page, and introduce paid results later? Since the results are two-dimensional, there is no clear way to distinguish a result that ranks better, and is therefore a desired position over other results. Google (and the rest) give linear results based on ranking priority, so the vertical component is much more important for ranking. Maybe a bit too soon to beyond this, since Cuil has only just started and is probably going to experiment a lot (hence the 2/3 column kayout option in bottom left of the screen).

The “Explore by Category” that appear for certain queries are neat, and actually do return interesting links towards content/results that may help me drill down further on a topic. But that’s pretty much in vain, since many of the queries I performed were answered with “no results found”, which wouldn’t be very strange, if it wasn’t for the fact that they boast billions of pages in the index (120+ billion!). Long tail search doesn’t seem to work, and basically if you type in more than 2-3 words, you’ll get scarce results if at all, but I am seeing improvements regarding this over time. Again, something that will probably change over time, simply too early for a more firm opinion. Sometimes, Cuil reports incorrect number of results compared to what you’re shown - for example “pamp for uiq symbian” returned 3 results, but showed only 2. Another bug?

Some of the queries returned results in multiple languages - for example French and English - all on the same page, side by side. I speak a few languages but if you are researching something, one language is really enough. It would be better if the application offered a choice to see results in other languages, if for example I didn’t find anything useful in English. This, however, didn’t happen too often, so I guess this was either a bug, or an experiment.

Notably, there is a clear absence of rich media results, or at least I didn’t get any, but I’m sure this will also change in the future.

Then there are numerous reports about the service being down due to overload. I haven’t experienced their down time intervals, but have frequently come upon the “no results found” scenario already mentioned. This is probably a start-up fluke, so I don’t expect this to happen too often.

Cuil could be an interesting new search option, especially since the people behind it certainly have the necessary experience and knowledge. I expect it to develop over the next months, and the real picture about its performance compared to ther search engines will be more complete then.

I have just read the BrowseRank document released by Microsoft regarding their work on a new alternative to PageRank and TrustRank.

Basically, the whole ranking algorithm comes down to giving more value to visitor behavior, as opposed to simply counting and valuating the number of links pointing towards a web page. Visitor clicks and time spent on a web page are key factors in determining its ranking potential.

The document explains the mathematical theories behind BrowseRank, and although this is more useful for search engineers, I got a pretty good picture of where they are going with this. The point is this is just the beginning, and there is a lot more work that’s going to happen before BrowseRank gains real validity.

Since it relies on recording user behavior, there are small obstacles in front of BrowseRank.

First of all there is the privacy issue (users have to opt-in for data to be gathered), and although their document states they used data from millions of visitors who opted in for the purpose of research, the question remains whether BrowseRank can actually work in the long term if it has to rely on users opting in to be tracked all the time. Not that we are not tracked already without permission by numerous web sites already, but that’s another story. I suppose social networking data can also be used to this effect (social bookmarking perhaps), but the other dimension is still critical - how will they manage to record time spent on pages in an easy and unobtrusive way?

What the document also mentions is that BrowseRank is a more valid measure of a page’s importance since it takes into account clicks and time spent on a page, and is thus more immune to manipulation techniques already present with PageRank. It is believed that a person will not click to a page and spend time there unless there is good content and their need for information has been answered. I think there is room for manipulation here as well, since you can theoretically engage an army of users to use a search engine, click on a specified result and go spend some time there, and gather “points” for a particular page to “help” it rank better for related search queries. Naturally, this is a very naive scenario, but quite plausible.

Nevertheless, BrowseRank is an interesting evolution of search, and is quite welcome in my opinion. Is it going to give Microsoft (Live Search) the edge to ride the same waves with Google and Yahoo? Well, I am just not sure. I think it’s going to take a lot more than that.

A really independent and safe way to rank content on the internet has yet to be found. Basically, if it involves people and their behavior, it’s going to be open to manipulation. Maybe we’ll get there some day, but not just yet… Anyway, my two cents.

So, Live Search has rolled out a new look for its home page. Well, it’s different, even interesting, but hopefully not the only thing they are going to change in their quest to improve their presence in the search arena.

In addition to this, Microsoft have published a document explaining their approach to ranking pages with a new rank criterion called BrowseRank (as opposed to Google’s PageRank, which they say is inferior to BrowseRank). Basically, BrowseRank is all about searcher online behavior (clicks and time spent on page) as a more accurate measure of a page’s importance, rather than simply relying on number of incoming links and on-page ranking factors. The BrowseRank document is available here, so check it out.
