Christina's LIS Rant

Category archives for information retrieval

So there I was, try all kinds of librarian ninja tricks on the fanciest, most expensive research databases money can buy (SciFinder, Reaxys, Inspec…) and no joy. Couldn’t find what I needed. I’m perfectly willing to admit that I don’t know all that much chemistry, but usually I do ok since I work with one…

in Geneva. This is the ACM Special Interest Group on Information Retrieval. Besides the academic types, this huge conference pulls a lot from the search engine industry and there’s a lot of interesting stuff. The twitter tag is #sigir2010 and there’s some bloggy coverage. (heh, today’s keynote – is the Cranfield paradigm outdated – um,…

I was happy to see that the authors published this article in PlosOne. I was following their work a while ago, but had lost track (plus, when asked, the last author implied that they had moved on to new projects). So here’s the citation and then I’ll summarize and comment. Divoli, A., Wooldridge, M., &…

Types of recommender systems

I’m still on this kick on recommender systems. I’m further encouraged by happening on a report on “discoverability” by the Minnesota librarians when looking for something else on JR’s blog. The report agrees that recommender systems are a more important trend. In standard information retrieval stuff, you’re going from whatever query the person puts in…

I’m on a sub-sub committee to evaluate evaluation of consideration of adding a new recommender system to our discovery tools across my parent institution’s libraries. The system costs money and programmer time (which we’re very short on), but more importantly, there’s a real estate issue, we already offer some similar tools, and even if the…

I ran across this piece again just now after having read it when it first came out in 20056: Foster, I. (2005). Service-Oriented Science. Science, 308(5723), 814-817. doi:10.1126/science.1110411 It’s a good piece and quite helpful. Google Scholar says it’s been cited 209 times, so that’s not terribly surprising. But here are some things that are…

A brief note. Remember when I told you about free to you research databases? Remember when some other librarians told you about a certain company negotiating for exclusive access to certain popular magazines, choking out other aggregators? Well, now these two things have something in common. Ebsco.

Cross-language information retrieval is an important research area with lots of activity. There are all kinds of elaborate algorithms and ways of doing it. There’s a lot of domain specificity and connotation kind of things that have been really improved in the past decade. Most people searching won’t really have the support of the fancy…

Is it possible or even desirable to have one search interface that serves every need? I have about 10 minutes to write this placeholder of a post. Hopefully, I’ll get the opportunity to revisit this topic near and dear to my heart later. I’ve often railed against naive librarians and administrators who insist we need…

Now that I’m not scared to look at my responses… This one doesn’t look so bad, so I’m sharing. Please do keep in mind that this was written in 2 hours, by a tired person, with tired fingers! — Christina K.
