A dataset of knowledge graph construction for data applications in the open government data domain
Listed in ScienceDB
As China's open government data movement enters a new stage centered on "value release" from "data openness," data applications have become a key link in the development and utilization of public data.
Description
The "data applications" launched on open data platforms at all levels of government have increased year by year, but the prominent heterogeneity among platforms is not conducive to the formation and orderly development of a national "single ledger" of data resources and a unified market.
As a structured and semantic approach to knowledge organization, knowledge graph technology provides an effective solution for the unified cross-platform description, semantic retrieval, and intelligent recommendation of data applications. This dataset focuses on the "data applications" published on China's open government data platforms. It collects relevant data from each platform since its launch through April 2026.

After cleaning, organizing, and merging, it ultimately constructs a data application knowledge graph dataset containing eight types of entities—data platforms, data applications, datasets, data competitions, developers, application types, application scenarios, and developer types—and eight types of relationships.
