Trip Database Blog

Well, the extra RAM is now in the system and there is no obvious improvement in speed. It’s invariably quicker at certain times of the day (peak times when memory was an issue).

The analysis of speed and the identification of bottlenecks is booked in to start mid-July. This will highlight code inefficiencies that can either be fixed as they go along or will need further work. Fingers crossed it’ll be the former.

I’ve noticed (and no doubt lots of others have as well) the pretty awful speed of TRIP in the last week or so. Just to say SORRY and that we are addressing the issues:

• As a short-term measure we are quadrupling the memory in our servers. This should boost speeds considerably and hopefully this will be in by either the end of this week or the start of the next.
• On a more medium term basis we are carrying out some sophisticated analysis of the site to identify where the bottlenecks are. We’re hoping that, once this has finished, we will be able to allocate resources at the problems. If we’re lucky the extra memory might sort everything out!

I use TRIP everyday so am acutely aware of the need for speed – we’ll get there….

Alexa is a leading resource for looking at the popularity of a website. Given the demise of the NLH Q&A I thought I would compare the NLH Q&A service with the NLH itself (click on image for larger size):

They say a picture is worth a thousand words!

There are some caveats associated with those figures (isn’t that always the way). But it’s certainly worth pondering.

I’m aware that this blog has been slow over the last week or so, the reason is simply I’ve been too busy with ‘all things TRIP’ to contemplate what to write about. Specifically, I’ve been heavily involved in 4 significant chunks of work:

• TRIP Spain – should launch very soon.
• TRIPanswers – I’ve been given the site to play with and/or test. I’ve started adding questions and answers and I’m very pleased. So far I’ve added 250 questions, only another 5,000 before we lauch (in about 2 months).
• Advertising – we’ve moved to a new advertising providers, I’m having to manually assign search terms we receive on TRIP to the advertisers advertising categories. This is very labour intensive, but it’ll hopefully be worth it!
• Winding up the NLH Q&A. Not much to do really, I’ve already started relaxing and moving my mental efforts to TRIPanswers…

I imagine I’ll start more regular posting soon(ish)

A great article on where search MAY be heading – Search 4.0: Putting Humans Back In Search

I’ve been intrigued by the notion of human search and the site Mahalo was/is of interest. The main interest has stemmed from the following:

• I feel the tweaking of search algorithms can only take you so far.
• Most users will only visit the first page of results.
• Given the experience within TRIP we have a pretty good idea what would constitute a good set of results.
• We have some experience in this area. A while back (so not up-to-date) we created a number of reviews e.g. statins or knee osteoarthritis.

The big problem is scale. We could create human-powered search results for the top 100 searches – but that’s scratching the surface. Perhaps I’ll do some mock-up and get users to ‘vote’ to see which they prefer.

Watch this space.

That’s according to Jakob Nielson (click here)!

…people are becoming much less patient when they go online.
Instead of dawdling on websites many users want simply to reach a site quickly, complete a task and leave…..Instead, many are “hot potato” driven and just want to get a specific task completed…..

The above has got me very excited as it fits in with my view based on observations over the years of running fairly successful websites. It’s also something Bandolier have long advocated with their frequent references to nuggets of evidence.

So what does the above suggest? Give small bite-sized chunks (nuggets) of evidence. More than that it’s giving people nuggets of evidence AND making them easy to find.

The NLH Q&A Service is great as it gives individuals rapid answers to their questions. The site is let down though by a poor search mechanism. So it’s not so great for others.

Resources like Clinical Knowledge Summaries have great content (arguably they are a large collection of nuggets) but again findability is a real issue.

Is there a solution? We hope so, and the launch of TRIPanswers in mid-summer will reveal our hand…

David Rothman has been to the Medical Librarian Association meeting and taken a video camera (click here).

This is a great use of technology…

As is this telectroscope.

I see that PubMed have rolled out a beta version of advanced search (click here).

While I play with the new features I really need to turn my attention to TRIP’s advanced search. Relative to the other part of the site it’s ‘weak’. Something for the last half of 2008!

I spotted a semantic web product called Calais a while back on (Reuters Wants The World To Be Tagged). Basically, it takes any document and ‘marks it up’ with various semantic web tags. I didn’t give it much thought till a blog post this morning Reuters Launches Calais 2.0 – Now With Pop-Culture which reports support for the pharmaceutical and medical world.

You can use this Calais Viewer link to try it out.

I enjoyed using it, but it still has a long way to go, the number of terms it recognises is limited.

Given my lack of vision I’m not sure how you can utilise knowing that ibuprofen is a ‘product’ and feverish illness is a ‘medical condition’. Perhaps one day it’ll become obvious…
