Construction of Linked Data Platform Implementing Feedback Data Model of Usage Records

摘要

Linked Open Data (LOD) is one of the methods that enables publishing and sharing of data on the Web, and makes data available for many applications. Maintaining the volume and quality of data in LOD requires to keep on engaging people in inputting data. One of the solutions is motivating data producers to input data by giving incentives. However, LOD does not track how data has been used by which applications. In order to track records, data of LOD need to be instantiated to represent who produced it and which applications used it. This paper proposes resource representation by hash value in order to realize instantiation of triple data efficiently according to the concept of RDF which uniquely express instance by URI. This paper also proposes data processing by utilizing the standard SPARQL query to instantiate triple data and feed back usage records to data producers. This paper contributes to showing feasibility of feedback model by building data platform and developing an application enabling people to entry information about spots in town, and by conducting a workshop with people living in Nagasaki city.
