| 10 | +DKN is a deep knowledge-aware network that takes advantage of knowledge graph representation in news recommendation. |
| 11 | +The main components in DKN is a KCNN module and an attention module: |
| 12 | +- The KCNN module is to learn from semantic-level and knowledge-level representations of news jointly. |
| 13 | +The multiple channels and alignment of words and entities enable KCNN to combine information from heterogeneous sources. |
| 14 | +- The attention module is to model the different impacts of a user’s diverse historical interests on current candidate news. |

| 19 | +- `data/` |
| 20 | + - `kg/` |
| 21 | + - `Fast-TransX`: an efficient implementation of TransE and its extended models for Knowledge Graph Embedding (from https://github.com/thunlp/Fast-TransX); |
| 22 | + - `kg.txt`: knowledge graph file; |
| 23 | + - `kg_preprocess.py`: pre-process the knowledge graph and output knowledge embedding files for DKN; |
| 24 | + - `prepare_data_for_transx.py`: generate the required input files for Fast-TransX; |
| 25 | + - `news/` |
| 26 | + - `news_preprocess.py`: pre-process the news dataset; |
| 27 | + - `raw_test.txt`: raw test data file; |
| 28 | + - `raw_train.txt`: raw train data file; |
| 29 | +- `src/`: implementations of DKN. |
| 30 | + |
| 31 | +> Note: Due to the pricacy policies of Bing News and file size limits on Github, the released raw dataset and the knowledge graph in this repository is only a small sample of the original ones reported in the paper. |
| 32 | +
|
| 33 | + |
| 34 | +### Format of input files |
| 35 | +- **raw_train.txt** and **raw_test.txt**: |
| 36 | + `user_id[TAB]news_title[TAB]label[TAB]entity_info` |
| 37 | + for each line, where `news_title` is a list of words `w1 w2 ... wn`, and `entity_info` is a list of pairs of entity id and entity name: `entity_id_1:entity_name;entity_id_2:entity_name...` |
| 38 | +- **kg.txt**: |
| 39 | + `head[TAB]relation[TAB]tail` |
| 40 | + for each line, where `head` and `tail` are entity ids and `relation` is the relation id. |
| 41 | + |
| 42 | + |
| 43 | +### Required packages |
| 44 | +The code has been tested running under Python 3.6.5, with the following packages installed (along with their dependencies): |
| 45 | +- tensorflow-gpu == 1.4.0 |
| 46 | +- numpy == 1.14.5 |
| 47 | +- sklearn == 0.19.1 |
| 48 | +- pandas == 0.23.0 |
| 49 | +- gensim == 3.5.0 |
| 50 | + |
| 51 | + |
| 52 | +### Running the code |
| 53 | +``` |
| 54 | +$ cd data/news |
| 55 | +$ python news_preprocess.py |
| 56 | +$ cd ../kg |
| 57 | +$ python prepare_data_for_transx.py |
| 58 | +$ cd Fast-TransX/transE/ (note: you can also choose other KGE methods) |
| 59 | +$ g++ transE.cpp -o transE -pthread -O3 -march=native |
| 60 | +$ ./transE |
| 61 | +$ cd ../.. |
| 62 | +$ python kg_preprocess.py |
| 63 | +$ cd ../../src |
| 64 | +$ python main.py (note: use -h to check optional arguments) |
| 65 | +``` |
