The role of alcohol outlet visits derived from mobile phone location data in enhancing domestic violence prediction at the neighborhood level

no code implementations26 Feb 2022 Ting Chang, Yingjie Hu, Dane Taylor, Brian M. Quigley

In this study, we propose to derive information about the alcohol outlet visits of the residents of different neighborhoods from anonymized mobile phone location data, and investigate whether the derived visits can help better predict DV at the neighborhood level.


A Review of Location Encoding for GeoAI: Methods and Applications

no code implementations7 Nov 2021 Gengchen Mai, Krzysztof Janowicz, Yingjie Hu, Song Gao, Bo Yan, Rui Zhu, Ling Cai, Ni Lao

A common need for artificial intelligence models in the broader geoscience is to represent and encode various types of spatial data, such as points (e. g., points of interest), polylines (e. g., trajectories), polygons (e. g., administrative regions), graphs (e. g., transportation networks), or rasters (e. g., remote sensing images), in a hidden embedding space so that they can be readily incorporated into deep learning models.

Aligning geographic entities from historical maps for building knowledge graphs

no code implementations5 Dec 2020 Kai Sun, Yingjie Hu, Jia Song, Yunqiang Zhu

Despite their valuable content, it is often challenging to access and use the information in historical maps, due to their forms of paper-based maps or scanned images.

An empirical study on the names of points of interest and their changes with geographic distance

1 code implementation21 Jun 2018 Yingjie Hu, Krzysztof Janowicz

While Points Of Interest (POIs), such as restaurants, hotels, and barber shops, are part of urban areas irrespective of their specific locations, the names of these POIs often reveal valuable information related to local culture, landmarks, influential families, figures, events, and so on.
