Louise Spiteri of Dalhousie University.
The presentation is on how we determine similarity and difference. She began with a dog and cat conversation. From the perspective of a alien, the clear differences we can see between a cat and a dog, are not as clear without the same frame of reference.
The notion of similarity or likeness underlies most approaches used in the design of bibliographic classification systems. In its simplest sense, classification is the arranging of things according to likeness and unlikeness.
The presentation now goes into the different classification systems and theories, discussing the differences between the theories, and the drawbacks of each.
She has been researching better ways of applying attributes to Folksonomy by using facets that are salient to the end users. These facets would be related to the original tags, not a predetermined set of tags. This was the most interesting and applicable point in the presentation, and it came as a off handed comment without any further detail.
