+## PwC4KPG dataset
+
+we extract the **fields, tasks, methods, datasets, metrics, titles and abstracts** from the raw corpus of PwC, provided that the paper has a full title and abstract.
+A total of 6,012 papers were extracted, of which 2,119 included all five categories of “keyphrases”, and the remaining 3,839 contained only some of them.
+Note that PwC does not contain the research fields as we define them, so we used the “main_collection” of methods as an alternative.
+
+**Train: 5,012 / Dev: 500 / Test: 500**  
+We randomly select 1,000 papers with full information,half of which are used for testing and the other half for validation. The remaining 5,012 served as the training set.
+
+**Paper: JASIST 2023, Generating keyphrases for readers: A controllable keyphrase generation framework.**
