from ckip_transformers.nlp import CkipWordSegmenter, CkipPosTagger, CkipNerChunker

Load models """"""""""""""

| We provide several pretrained models for the NLP tools. | 我們提供了一些適用於自然語言工具的預訓練的模型。

.. code-block:: python

Initialize drivers

ws_driver = CkipWordSegmenter(model="bert-base") pos_driver = CkipPosTagger(model="bert-base") ner_driver = CkipNerChunker(model="bert-base")

| One may also load their own checkpoints using our drivers. | 也可以運用我們的工具於自己訓練的模型上。

.. code-block:: python

Initialize drivers with custom checkpoints

ws_driver = CkipWordSegmenter(model_name="path_to_your_model") pos_driver = CkipPosTagger(model_name="path_to_your_model") ner_driver = CkipNerChunker(model_name="path_to_your_model")

| To use GPU, one may specify device ID while initialize the drivers. Set to -1 (default) to disable GPU. | 可於宣告斷詞等工具時指定 device 以使用 GPU，設為 -1 （預設值）代表不使用 GPU。

.. code-block:: python

Use CPU

ws_driver = CkipWordSegmenter(device=-1)

Use GPU:0

ws_driver = CkipWordSegmenter(device=0)

Run pipeline """""""""""""""

| The input for word segmentation and named-entity recognition must be a list of sentences. | The input for part-of-speech tagging must be a list of list of words (the output of word segmentation). | 斷詞與實體辨識的輸入必須是 list of sentences。 | 詞性標記的輸入必須是 list of list of words。

.. code-block:: python

Input text

text = [ "傅達仁今將執行安樂死，卻突然爆出自己20年前遭緯來體育台封殺，他不懂自己哪裡得罪到電視台。", "美國參議院針對今天總統布什所提名的勞工部長趙小蘭展開認可聽證會，預料她將會很順利通過參議院支持，成為該國有史以來第一位的華裔女性內閣成員。", "空白也是可以的～", ]

Run pipeline

ws = ws_driver(text) pos = pos_driver(ws) ner = ner_driver(text)

| The POS driver will automatically segment the sentence internally using there characters '，,。：:；;！!？?' while running the model. (The output sentences will be concatenated back.) You may set delim_set to any characters you want. | You may set use_delim=False to disable this feature, or set use_delim=True in WS and NER driver to enable this feature. | 詞性標記工具會自動用 '，,。：:；;！!？?' 等字元在執行模型前切割句子（輸出的句子會自動接回）。可設定 delim_set 參數使用別的字元做切割。 | 另外可指定 use_delim=False 已停用此功能，或於斷詞、實體辨識時指定 use_delim=True 已啟用此功能。

.. code-block:: python

Enable sentence segmentation

ws = ws_driver(text, use_delim=True) ner = ner_driver(text, use_delim=True)

Disable sentence segmentation

pos = pos_driver(ws, use_delim=False)

Use new line characters and tabs for sentence segmentation

pos = pos_driver(ws, delim_set='\n\t')

| You may specify batch_size and max_length to better utilize you machine resources. | 您亦可設置 batch_size 與 max_length 以更完美的利用您的機器資源。

.. code-block:: python

Sets the batch size and maximum sentence length

ws = ws_driver(text, batch_size=256, max_length=128)
