# JarKA
**JarKA** tackles the attribute heterogeneity problem by the interaction-based matching model when aligning cross-lingual knowledge graphs, and also further incorporates structure information by a jointly-trained framework. To alleviate the conflicts generated by the two modules, three merge strategies are adopted such that the most confident seeds can be selected appropriately.
## Whole Framework
## Dependencies
* Python 3.6+
* Pytorch "1.1.0"+
* CPU/GPU
* Jieba
* MeCab
* ...
## How to run
+ Directory *dbp_15k*: stores three datasets, zh_en, fr_en, and ja_en. You can download from [here](https://pan.baidu.com/s/1eJjlpxo1oLPlqbJJvuEHeg) with password:r9a7 ;
+ Directoty *model*: saves JarKA code.
Taking, *zh_en* dataset, for example, we demostrate how to run JarKA model:
### 1. Preprocess the data
+ You need first download *dbp15k* dataset, and then go to the dirs *./dbp15k/zh_en/*, run the following code sequentially to generate essential data files:
+ *build_vocab_dict.py*: to build vocabulary dict (*whole_vocab_split*) and the corpus for pretraining the NMT (*zh_en_des*);
+ *filter_att.py*: to filter the popular attributes which appear at least 50 times in all attribute triplets, and then match each attribute to an id. (*att2id_fre.p*);
+ *generate_popular_attrs.py*: filter and sort the attributes by popularity and seclect top-20 attribute triplets for each entity (*filter_sort_zh/en_lan_att_filter.p*)
### 2. Pretrain the NMT model.
Go the dirs *model/*
+ Copy all the files in the dir *./dbp15k/zh_en/* to *./data/*
+ Run translate.py, and save the checkpoints.
### 3. Run the JarKA model.
`python jarka_main.py --merge {merge_strategy}`
Where `{merge_strategy} contains ['multi_view', 'score_based', 'rank_based'] `
## Extensive Experiments
### Dataset discription
We evaluate the proposed model on three datasets. One is a well-adopted public dataset named DBP15K, the other two, named DBP15K-1 and DBP15K-2, modify DBP15K. DBP15K-1 loosens the constraint as 2 self-contained relationship triplets, and DBP15K-2 further removes the self-contained constraint. Thus, the clustering of the three datasets is different. Table 1 shows the statistics of the datasets.
The *dbp15k-1* dataset is also avaliable [online](https://pan.baidu.com/s/1wdGV49pscjYcluEXO14o_g).(password: aclg)
### Overall experiment results
### Sensitivity to Graph Clustering
We compare JarKA and BootEA on three ZH-EN datasets, which shows that both of them perform poorer when the clustering coefficient (cc) of the dataset is smaller. But their performance gap increases with the decrease of cc, indicating BootEA is more sensitive to the clustering characteristics of the graph than JarKA, as BootEA only models the structures.
