[AAAI 24 (oral)] TEILP: Time Prediction over Knowledge Graphs via Logical Reasoning

This repository contains the code for the paper TEILP: Time Prediction over Knowledge Graphs via Logical Reasoning.

Introduction

This is a follow-up work of TILP: Differentiable Learning of Temporal Logical Rules on Knowledge Graphs. We convert TKGs into a temporal event knowledge graph (TEKG) which equips us to develop a differentiable random walk approach. We also introduce conditional probability density functions, associated with the logical rules involving the query interval, using which we arrive at the time prediction.

Random walk:

# For wiki, YAGO:
python random_walk_for_interval_datasets.py --dataset {$dataset name}

# For icews14, icews05-15, gdelt100:
python random_walk_for_timestamp_datasets.py --dataset {$dataset name}

# Examples:
# python random_walk_for_interval_datasets.py --dataset wiki
# python random_walk_for_timestamp_datasets.py --dataset icews14

Rule learning:

python main.py --dataset {$dataset name} --train

# Examples:
# python main.py --dataset YAGO --train
# python main.py --dataset icews14 --train

Rule application:

python main.py --dataset {$dataset name} --test --from_model_ckpt {$path to saved model}

# Examples:
# python main.py --dataset YAGO --test --from_model_ckpt ../exps/YAGO_24-02-17-20-57/ckpt/model-30
# python main.py --dataset icews14 --test --from_model_ckpt ../exps/icews14_24-02-18-11-03/ckpt/model-30

Print rules:

# Find the rules and scores in output/{$dataset name}/rule_scores.
# Parameters:
# - rule_patterns: relations and temporal relations (Example in YAGO: query rel: 4, rule: 7 10 7 10 14 ukn af bf af bf; Translation: isMarriedTo(x, y, I_q) <- diedIn(x, e1, I1) and wasBornIn^{-1}(e1, e2, I2) and diedIn(e2, e3, I3) and wasBornIn^{-1}(e3, e4, I4) and isMarriedTo^{-1}(e4, y, I5) and unknown(I_q, I_1) and after(I_1, I_2) and before(I_2, I_3) and after(I_3, I_4) and before(I_4, I_5) and unknown(I_5, I_q))
# - rule_scores: score of the rules
# - refType_scores: score of reference types shared by all the rules (use which event in the body and its start time or end time)
