Last week I was privileged to present at the London Information and Knowledge Exchange (LIKE) on the topic of “Think outside the search box: a AI-based approach to search strategy formulation“. LIKE are unusual in that their meetings often take place in the evening, accompanied by drinks and dinner. I’d not presented in a pub before, at least not over dinner, and had to work hard to resist the temptation to segue into some sort of ill-advised attempt at stand up comedy. It’s amazing what the combination of a hand held mic and a pint of Young’s pale ale can do…

Researchers, information professionals, patent searchers and recruiters all require effective search to perform their duties, often relying on form-based query builders. However, these tools require the use of complex Boolean syntax and offer limited support for error checking or optimization. Moreover, this approach precipitates a number of other issues:

  • Systematic literature review is the cornerstone of evidence-based medicine, but the search strategies used often contain errors
  • Search strategies can be improved and optimised thorough peer-review, but the platforms for this practice are rarely open to public scrutiny
  • Managing search strategies using document-centric tools such as MS Word or PDF introduces errors through unwanted conversion of control characters (e.g. quotation marks and truncation symbols), removal of spaces, addition of line breaks etc.
  • Copy and pasting searches from documents/spreadsheets into search boxes introduces further errors
  • Publishing search strategies as supplementary materials scales poorly and data can become lost over time

So I’m pleased to share the following webinar, which discusses these challenges and offers some solutions. It is presented by Farhad Shokraneh, who is an information specialist in the Cochrane Schizophrenia Group at the University of Nottingham. He is co-author of search chapter in Cochrane Handbook and an invited editor for Systematic Reviews and World Journal of Meta-Analysis. The webinar was kindly hosted by the Knowledge Synthesis Interest Group of the Canadian Health Libraries Association.

Summer’s finally here, and with it comes another milestone for 2dSearch: alternative visualisations. The default ‘Nested’ view has its strengths, but it isn’t to everyones liking. So we’ve added two completely new ways to view, understand and optimise your searches:

  • Tree View, which uses the metaphor of the family tree, with a root node at the top and successive generations of children below
  • Inline View, which maps hierarchical structure onto physical structure with groups aligned a common midline, allowing a traditional left-to-right ‘Boolean string’ reading

And of course you still have the Nested View, which maps hierarchical structure onto a series of nested containers. And all of this for free! There’s lots more details in our Medium post, but for the best experience just try them out for yourself.

Just published the following video on Youtube, which complements last week’s piece on the topic of How to debug and optimise Boolean strings. As always, comment & feedback welcome.

Struggling with complex Boolean searches? Editing Boolean strings is inefficient & error prone.

With 2dSearch you can visualize your search in 2D, then drag & drop blocks to optimise and refine. Use automated query suggestions to refine your search. Works with Bing, Google, Google Scholar, PubMed, TRIP, Epistemonikos and more. When you’re done, you can save & share your own collection of search templates and best practices.

Just published the following video on Youtube, Twitter et al. Sharing here for completeness!

Not seeing the results you expected? Debugging complex searches can be a frustrating experience. Don’t waste time editing Boolean strings: find and fix errors the visual way. Visualise your search in 2D, switch parts on & off, enable and disable terms…experiment and optimise, then save and share.

Most of us are familiar Google Scholar: a freely available subset of Google that indexes the world’s scholarly literature across a range of disciplines. With its database of over 389 million documents including articles, citations and patents, it has become an indispensable resource for scholars and researchers across the globe. Which is why we recently added Google Scholar integration to 2dSearch, thereby offering a tool of immediate utility to anyone wishing to search the world’s scientific literature in a systematic manner.

Now, we’d always known that despite its extensive index, searching GS is subject to the ‘secret sauce’ of Google’s search algorithms, and that this can compromise the ability of users to formulate sophisticated, reproducible searches. But what we perhaps didn’t realise was just how limited that support is. In particular, GS seems to support only 1 set of synonyms (i.e. a substring with terms separated by OR). For example, the following search string would seem to parse correctly:

If you were tasked with designing a universal framework for search query formulation, where would you start? Well, you could start from a command-line paradigm. After all, that’s the approach adopted by most query builders and ‘advanced search’ forms. But convention aside, is that really the best place to start? Personally, I am not convinced – IMHO command line approaches reflect the days when searches were conducted via remote terminals to subscription databases, and in that respect, they represent the past, not the future. Moreover, using Boolean strings to articulate complex information needs suffers from a number of fundamental shortcomings, in particular regarding scalability, efficiency and transparency. So what’s the alternative?
