The implementation of TransE [1], TransH [2], TransR [3], TransD [4] for knowledge representation learning (KRL). The overall framework is based on TensorFlow. We use C++ to implement some underlying operations such as data preprocessing and negative sampling. For each specific model, it is implemented by TensorFlow with Python interfaces so that there is a convenient platform to run models on GPUs.

These codes will be gradually integrated into the new framework [OpenKE].

If you have a new idea and need to implement its code, you just need to change Python interfaces for your customized model. Read these codes, you will find that to change the class TransXModel will meet your needs.

More results about models can be found in ("https://github.com/thunlp/KB2E").

Datasets are required in the following format, containing three files:

triple2id.txt: training file, the first line is the number of triples for training. Then the follow lines are all in the format (e1, e2, rel).

entity2id.txt: all entities and corresponding ids, one per line. The first line is the number of entities.

relation2id.txt: all relations and corresponding ids, one per line. The first line is the number of relations.

You can download FB15K and WN18 from [Download], and the more datasets can also be found in ("https://github.com/thunlp/KB2E").

bash make.sh

To train models based on random initialization:

1. Change class Config in transX.py

    class Config(object):
   
    	def __init__(self):
    		...
    		lib.setInPath("your training data path...")
    		self.testFlag = False
    		self.loadFromData = False
    		...
   

2. python transX.py

To train models based on pretrained results:

1. Change class Config in transX.py

    class Config(object):
   
    	def __init__(self):
    		...
    		lib.setInPath("your training data path...")
    		self.testFlag = False
    		self.loadFromData = True
    		...
   

2. python transX.py

To test your models:

1. Change class Config in transX.py

    class Config(object):
   
    	def __init__(self):
    		...
    		test_lib.setInPath("your testing data path...")
    		self.testFlag = True
    		self.loadFromData = True
    		...
   

2. python transX.py
