dict_file format

[KoichiYasuoka]

Now I'm trying to train with nagisa.fit by UD_Classical_Chinese-Kyoto (漢文) under 4-level classified-POS-system (4階層品詞). See my blog what I tried. I found dict_file parameter in nagisa.fit and I guessed it an outer dictionary (外部辞書). But I could not find any explanation or usage of the dict_file in your document. How do I use dict_file? Does it (and train_file) support classified-POS-system?

Thank you for using nagisa. The dict_file parameter is used as an outer dictionary, as you guessed. I'm sorry I didn't fill out the details in my document.

Could you refer to sample.dict in sample_datasets. The dict_file is consists of tab delimiters (word\tpostag) and it will be effective for classifying POS tags.

I saw your blog and ran a program to train UD_Classical_Chinese-Kyoto. By tuning the hyperparameters, I was able to obtain even better the test POS-tagging f1-score. If you are interested in it, please run the program below.

nagisa.fit(train_file="lzh_kyoto-ud-train.txt",dev_file="lzh_kyoto-ud-dev.txt",test_file="lzh_kyoto-ud-test.txt",dict_file="lzh_udkanbun-dict.txt",model_name="lzh_kyoto-nagisa", dim_tagemb=32, decay=3)
