The source code used for paper "Empower Entity Set Expansion via Language Model Probing", published in ACL 2020.

Data

You can download the Wiki and APR datasets from the following links:

https://www.dropbox.com/sh/7aejy7t1bi9cjdj/AABIK71EcGtI2YAU-IoikK0xa?dl=0

After downloading the dataset, put them under the folder "./data/"

Run

For Wiki dataset, run

python src/main.py -dataset data/wiki/ -m 2 -gen_thres 3

For APR dataset, run

python src/main.py -dataset data/apr/ -m 2 -gen_thres 1

Results for each query will be saved under "./data/[DATA]/results"

Pretrained Embedding

To get pre-trained embedding for your own dataset, you need to provide "entity2id.txt" and "sentences.json". Please refer to SetExpan and HiExpan for the preprocessing code.

After putting the required files in your dataset folder "./data/[DATA]", you can run the following command to get the pretrained embedding:

python src/PretrainedEmb.py -dataset data/[DATA]
