Project Struct

• datas: to store corpus
• models: to store item vectors for movies
• utils: a collection of tool functions

Usage

0. Compile fasttext under root of the project

1. Process corpus, the data file would be generated under ./datas/.

$ cd datas && tar -xzvf corpus.tar.gz
$ cd ..
$ python utils/process.py

2. Train model by running fasttext. Please refer to ./run.sh for other configuration.

$ ./fasttext skipgram -input ./datas/doulist_0804_09.movie_id -output ./models/fasttext_model_0804_09_skipgram -minCount 5 -epoch 50 -neg 100

3. Here's a result from the default configuration.

$ python utils/eval.py
movie_name_id_dict is 130206 from [./datas/doulist_0804_09.json]
movie_name_id_dict is 130206 from [./datas/doulist_0804_09.json]
movie_id_name_dict is 130206 from [./datas/doulist_0804_09.json]

MovieTaster-Open

使用Item2Vec做电影推荐

参考:

• Barkan, Oren, and Noam Koenigstein. "Item2vec: neural item embedding for collaborative filtering." Machine Learning for Signal Processing (MLSP), 2016 IEEE 26th International Workshop on. IEEE, 2016.
• JayveeHe, https://github.com/JayveeHe/MusicTaster. Github.

Demo>

原理详情请参考>

目录结构

• datas: 存放语料
• models: 存放电影向量
• utils: 工具类，包括生成推荐电影列表等

使用说明

0. 在根目录下载并编译fasttext

1. 处理语料。结束后将在./datas/下生成fasttext所需要的格式

$ cd datas && tar -xzvf corpus.tar.gz
$ cd ..
$ python utils/process.py

2. 参考./run.sh中生成词向量的参数配置，任选一个。

$ ./fasttext skipgram -input ./datas/doulist_0804_09.movie_id -output ./models/fasttext_model_0804_09_skipgram -minCount 5 -epoch 50 -neg 100

3. 查看模型效果

$ python utils/eval.py
movie_name_id_dict is 130206 from [./datas/doulist_0804_09.json]
movie_name_id_dict is 130206 from [./datas/doulist_0804_09.json]
movie_id_name_dict is 130206 from [./datas/doulist_0804_09.json]
