This is our PyTorch implementation for the paper:
Xiang Wang, Tinglin Huang, Dingxian Wang, Yancheng Yuan, Zhenguang Liu, Xiangnan He and Tat-Seng Chua (2021). Learning Intents behind Interactions with Knowledge Graph for Recommendation. Paper in arXiv. In WWW'2021, Ljubljana, Slovenia, April 19-23, 2021.
Knowledge Graph-based Intent Network (KGIN) is a recommendation framework, which consists of three components: (1)user Intent modeling, (2)relational path-aware aggregation, (3)indepedence modeling.

The code has been tested running under Python 3.6.5. The required packages are as follows:
- pytorch == 1.5.0
- numpy == 1.15.4
- scipy == 1.1.0
- sklearn == 0.20.0
- torch_scatter == 2.0.5
- networkx == 2.5
To demonstrate the reproducibility of the best performance reported in our paper and faciliate researchers to track whether the model status is consistent with ours, we provide the best parameter settings (might be different for the custormized datasets) in the scripts, and provide the log for our trainings.
The instruction of commands has been clearly stated in the codes (see the parser function in utils/parser.py).

- Amazon-book dataset
python main.py --dataset amazon-book --dim 64 --lr 0.0001 --sim_regularity 0.00001 --batch_size 1024 --node_dropout True --node_dropout_rate 0.5 --mess_dropout True --mess_dropout_rate 0.1 --gpu_id 0 --context_hops 3
- Alibaba-iFashion dataset
python main.py --dataset alibaba-fashion --dim 64 --lr 0.0001 --sim_regularity 0.0001 --batch_size 1024 --node_dropout True --node_dropout_rate 0.5 --mess_dropout True --mess_dropout_rate 0.1 --gpu_id 0 --context_hops 3
Important argument:
sim_regularity- It indicates the weight to control the independence loss.
- 1e-4(by default), which uses 0.0001 to control the strengths of correlation.
We provide three processed datasets: Amazon-book, Last-FM, and Alibaba-iFashion.
- You can find the full version of recommendation datasets via Amazon-book, Last-FM, and Alibaba-iFashion.
- We follow KB4Rec to preprocess Amazon-book and Last-FM datasets, mapping items into Freebase entities via title matching if there is a mapping available.

train.txt- Train file.
- Each line is a user with her/his positive interactions with items: (
userIDanda list of itemID).
test.txt- Test file (positive instances).
- Each line is a user with her/his positive interactions with items: (
userIDanda list of itemID). - Note that here we treat all unobserved interactions as the negative instances when reporting performance.
user_list.txt- User file.
- Each line is a triplet (
org_id,remap_id) for one user, whereorg_idandremap_idrepresent the ID of such user in the original and our datasets, respectively.
item_list.txt- Item file.
- Each line is a triplet (
org_id,remap_id,freebase_id) for one item, whereorg_id,remap_id, andfreebase_idrepresent the ID of such item in the original, our datasets, and freebase, respectively.
entity_list.txt- Entity file.
- Each line is a triplet (
freebase_id,remap_id) for one entity in knowledge graph, wherefreebase_idandremap_idrepresent the ID of such entity in freebase and our datasets, respectively.
relation_list.txt- Relation file.
- Each line is a triplet (
freebase_id,remap_id) for one relation in knowledge graph, wherefreebase_idandremap_idrepresent the ID of such relation in freebase and our datasets, respectively.
