Neural-based Completion of a Global Point-of-Interest Database - Naver Labs Europe
    30 August 2019
    Meylan, France
    Job Type
    Start date
    February 2019 - earlier starting date is also possible.
    5-6 months


    Applications that process Point-of-Interest (POI) data, such as recommender systems, trip planners, or artificial intelligence (AI) based personal assistants, are omni-present nowadays. However, the success of such applications critically depends on the quality of the ingested data, and most importantly the completeness of supporting databases [1, 2]. Existing work on automatic data completion approaches has only recently partially considered the task for Points-of-Interest [3]. Such entities have a number of distinctive properties - notably multiscript names, geo-spatial identity, and temporally defined context -, which make the task more challenging.


    The successful candidate will work on neural-based data completion techniques, applied to a global database of Points-of-Interest. Possible axes of work include identifying appropriate representations for spatial and temporal information, exploring the effect of multi-script and multi-language information, and experimenting with corresponding models.
