A key task in formulating effective search strategies is the identification of appropriate keywords and controlled vocabulary terms. Interactive features such as query expansion can play a key role in supporting these tasks. In this presentation we investigate a variety of methods for interactive query expansion based on manually curated resources (e.g. ontologies and terminologies) and on distributional methods (e.g. unsupervised machine learning). The results demonstrate the utility of distributional models and the value of using ngram order to optimise precision and recall. This work was due to be presented at the ISKO UK event Using knowledge organization to deliver content (which will hopefully be rescheduled later this year).

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…

I know the official publicity may not have reached your inbox just yet, but here’s a sneak peek at this year’s lineup for Search Solutions 2019. For those unfamiliar with the event, it is described as:

… the premier UK forum for presentation of the latest innovations in search and information retrieval. In contrast to other major industry events, Search Solutions aims to be highly interactive, with attendance strictly limited. The programme includes presentations, panels and keynote talks by influential industry leaders on novel and emerging applications in search and information retrieval.

As last year we’ll be preceding the event with a tutorials day on November 25, which will offer conference attendees and local participants a stimulating and informative selection of practical training courses reflecting current topics and state-of-the-art methods in search and information retrieval. More on that later! Meanwhile, here is the provisional programme thus far:
