Taxonomy Boot Camp London 2018
This was my second Taxonomy Boot Camp London (TBCL), attending as a representative of NetIKX, one of the supporters of the event. I had been impressed by the quality of talks at last year’s Boot Camp and the standard this year equalled, if not exceeded, that of the previous event. It was fascinating to see how some of the topics of last year (such as ‘fake news’ and big data) were still current, but the conversation around these issues has moved on and deepened.
Not just two sides to every story
The opening keynote from Paul Rissen expanded on the issues of truth, free speech and fact checking to explore ways in which information environments tackle these problems, with varying success: ‘fact checking’ alone does not work because ‘true v false’ is no longer the key issue. We are faced with the ‘Russian firehose of falsehood’ propaganda model whereby we are overwhelmed with so many different narratives that nobody knows what to believe or do. The aim is to distract and discourage: the well-meaning maxim of ‘question everything’ has been distorted into ‘trust no-one’. The artificial format which presents (only) two opposing sides to every story and aims to give equal weight to both, is still prevalent in broadcast journalism and ‘free speech’ is all too often understood to mean a lack of regulation, ignoring the fact that it is automatically easier for a powerful group to express its ideas freely. These issues impact on how we manage online environments, especially where value tends to be measured by the number of clicks and likes. The agile philosophy values ‘moving fast and breaking things’, but maybe we need to move fast and fix things! Community management needs to value diversity, respect the intelligence of users and reward positive behaviour rather than simply punishing negative behaviour. We should have ‘strong opinions, loosely held’ – there is nothing wrong with changing your mind in the face of new evidence.
Machines learn what we teach them
Machine learning was also a recurring theme, with several speakers addressing the limitations of reliance on algorithms and the ways in which taxonomy can enhance machine learning, an area which is still under-exploited. Machine learning and AI are valuable as they allow us to see patterns in information, but we need to be aware of the limits of machine classification – such as the well-publicised cases of algorithms ‘learning’ from and replicating human social and cultural biases. Machines are useful for pattern recognition and concept extraction, but selecting suitable training sets is not easy. We must remember that machines learn from us and we need to be careful what we teach them!
Taxonomy alone cannot fix enterprise search
The second day’s keynote, by Tom Reamy of KAPS Group, covered many of these issues and questioned some of the received wisdom about the value of taxonomies: it’s a good thing that we no longer need to explain what a taxonomy is, but the downside is that there are a lot of bad ones out there. Taxonomies are often seen as the solution to poor enterprise search, but tagging documents is laborious and users are resistant to being forced to choose tags. While taxonomies add structure to unstructured content, automatic tagging provides limited accuracy: a hybrid model combining taxonomy and text analytics is a better foundation for an enterprise solution.
