A construction of knowledge graph from open data

online

Since the open data movement was initiated in Taiwan, datasets are available in the open data platform. There exists a big challenge of data integration with having the huge amount of datasets. Take 'trail' datasets as an example. The Forest Bureau only concerns geospatial locations on the maps, while Tourism Bureau only concerns tourism information for a trial and Ministry of Health and Welfare only takes care about the consumption of calories as people walk on a trail. Each governmental department only concerns the affairs they charge of. Data management is often limited in the authority of a governmental department. There lacks a framework for integration of open data for making it to operable knowledge. This presentation is going to introduce how to utilize linked data technology for transferring agricultural traceable product data and civic IoT data to knowledge graphs and their applications.
