PlentyOfFish = PlentyOfData (talk by Thomas Levi) — Feb 19

Thurs, Feb 19, 2:30–4 pm, Abby B121

Abstract: As the world’s largest free dating site, Plenty Of Fish would
like to be able to match with and allow users to search for people with
similar interests. However, we allow our users to enter their interests as
free text on their profiles. This presents a difficult problem in
clustering, search and machine learning if we want to move beyond simple
‘exact match’ solutions to a deeper archetypal user profiling and thematic
search system. Some of the common issues that arise are misspellings,
synonyms (e.g. biking, cycling and bicycling) and similar interests (e.g.
snowboarding and skiing) on a several million user scale. In this talk I
will demonstrate how we built a system utilizing topic modelling with
Latent Dirichlet Allocation (LDA) on a several hundred thousand word
vocabulary over ten million+ North American users and explore its
applications at POF.
