Prerequisites

scikit-learn==0.24.1
nltk==3.5

Example

1. Put the data folder under the project directory which contains the source code and dependencies. Run all probing experiments from the project directory and perform analysis using the following command. BERT embeddings for pairs in all datasets are pre-stored as vector files in the data folder for direct usages.

bash run_exp.sh

2. Results are saved in files, which can be found under ./data/fullprobe/full-test/test-3996

3. The original datasets used in experiments are located under ./data/raw_datasets/full

   Each line is an entry for a pair, consisting of context-1, context-2, word-1, word-2, sense-1, sense-2, details (the path that a IS-A pair is sampled from, offsets from leaf, number of hops of the pair, starting depth is not used), label. Label 1 denotes the IS-A relation, and 0 denotes not IS-A relation.

   An example data instance is as follows. we took a turn in the park he enjoyed selling but he hated the travel turn travel Lemma('turn.n.12.turn') Lemma('travel.n.01.travel') {'path': "[Synset('turn.n.12'), Synset('walk.n.04'), Synset('travel.n.01'), Synset('motion.n.06'), Synset('change.n.03'), Synset('action.n.01'), Synset('act.n.02'), Synset('event.n.01'), Synset('psychological_feature.n.01'), Synset('abstraction.n.06'), Synset('entity.n.01')]", 'offset': (0, 2), 'hops': 2, 'starting_depth_in_path': 0} 1
