Metadata Harmonization and Semantic Search for ArcGIS Online
Track: Education and Training
Authors: Yingjie Hu
This research addresses two challenges in geoportals, namely the topic heterogeneity brought by multiple metadata standards as well as the lack of established semantic search in Linked-Data-driven geoportals. We propose a workflow which combines natural language processing and semantic web technologies. To demonstrate our result, we implement a prototypical geoportal using a sample dataset from Esri's ArcGIS Online.
