Global Heat map and learning to rank
Reverse geocoding is one of HERE Technologies most heavily used services and a huge amount of data is produced by its access logs. From this data geocodes can be extracted and then counted with respect to some cellulation of the earth creating a sparse heat map. For our Place & Address Search products we use such a heat map to define a notion of relative place importance useful to index and rank addresses and places. However, the large data size, sparsity, and variations in traffic from which different heat maps may be derived, makes faithful visualization and comparison a challenge.
In this talk I will focus on describe how we are able to collect, visualize and compare this information and how we make use of it, together with machine learning techniques, to improve our address autocompletion service.
