This repository is a subproject of THU-OpenSK, and all subprojects of THU-OpenSK are as follows.
An extremely fast implementation of TransE [1], TransH [2], TransR [3], TransD [4], TranSparse [5] for knowledge representation learning (KRL) based on our previous pakcage KB2E ("https://github.com/thunlp/KB2E") for KRL. The overall framework is similar to KB2E, with some underlying design changes for acceleration. This implementation also supports multi-threaded training to save time.
These codes will be gradually integrated into the new framework [OpenKE].
Because the overall framework is similar, we just list the result of transE(previous model) and new implemented models in datesets FB15k and WN18.
CPU : Intel Core i7-6700k 4.00GHz.

| Fast-TransD (n = 100, threads = 8, rounds = 1000) | 309 | 297 | 78.5 | 91.9 | 201s |
More results can be found in ("https://github.com/thunlp/KB2E").
Datasets are required in the following format, containing three files:
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.
train2id.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). Note that train2id.txt contains ids from entitiy2id.txt and relation2id.txt instead of the names of the entities and relations.
We provide FB15K and WN18, and more datasets can be found in ("https://github.com/thunlp/KB2E"). If you use your own datasets, please check the format of your training file. Files in the wrong format may cause segmentation fault. Datasets in KB2E also need to change their formats before training.
