## Evolving Concept Co-occurrence Graph

It is the official **Evolving Concept Co-occurrence Graph** dataset of paper *Exploring and Verbalizing Academic Ideas by Concept Co-occurrence*.


To train our model for temporal link prediction, we first collect 240 essential and common queries from 19 disciplines and one special topic (COVID-19). Then, we enter these queries into the paper database to fetch the most relevant papers between 2000 and 2021 with Elasticsearch, a modern text retrieval engine that stores and retrieves papers. Afterward, we use information extraction tools including [AutoPhrase](https://github.com/shangjingbo1226/AutoPhrase) to identify concepts. Only high-quality concepts that appear in our database will be preserved. Finally, we construct 240 evolving concept co-occurrence graphs, each containing 22 snapshots according to the co-occurrence relationship. The statistics of the concept co-occurrence graphs are provided in Appendix I.
