For models trained using [Universal +Dependencies](https://universaldependencies.org) corpora, the training data has +been updated to UD v2.5 (v2.6 for Japanese, v2.3 for Polish) and Dutch has been +extended to include both UD Dutch Alpino and LassySmall. + + + +**Models:** [Models directory](/models) **Benchmarks: ** +[Release notes](https://github.com/explosion/spaCy/releases/tag/v2.3.0) + + + +### Chinese {#chinese} + +> #### Example +> ```python +> from spacy.lang.zh import Chinese +> +> # Load with "default" model provided by pkuseg +> cfg = {"pkuseg_model": "default", "require_pkuseg": True} +> nlp = Chinese(meta={"tokenizer": {"config": cfg}}) +> +> # Append words to user dict +> nlp.tokenizer.pkuseg_update_user_dict(["中国", "ABC"]) + +This release adds support for +[pkuseg](https://github.com/lancopku/pkuseg-python) for word segmentation and +the new Chinese models ship with a custom pkuseg model trained on OntoNotes. +The Chinese tokenizer can be initialized with both `pkuseg` and custom models +and the `pkuseg` user dictionary is easy to customize. + + + +**Chinese:** [Chinese tokenizer usage](/usage/models#chinese) + + + +### Japanese {#japanese} + +The updated Japanese language class switches to +[SudachiPy](https://github.com/WorksApplications/SudachiPy) for word +segmentation and part-of-speech tagging. Using `sudachipy` greatly simplifies +installing spaCy for Japanese, which is now possible with a single command: +`pip install spacy[ja]`. + + + +**Japanese:** [Japanese tokenizer usage](/usage/models#japanese) + + + +### Small CLI updates + +- `spacy debug-data` provides the coverage of the vectors in a base model with + `spacy debug-data lang train dev -b base_model` +- `spacy evaluate` supports `blank:lg` (e.g. `spacy evaluate blank:en + dev.json`) to evaluate the tokenization accuracy without loading a model +- `spacy train` on GPU restricts the CPU timing evaluation to the first + iteration + +## Backwards incompatibilities {#incompat} + + + +If you've been training **your own models**, you'll need to **retrain** them +with the new version. Also don't forget to upgrade all models to the latest +versions. Models for earlier v2 releases (v2.0, v2.1, v2.2) aren't compatible +with models for v2.3. To check if all of your models are up to date, you can +run the [`spacy validate`](/api/cli#validate) command. + + + +> #### Install with lookups data +> +> ```bash +> $ pip install spacy[lookups] +> ``` +> +> You can also install +> [`spacy-lookups-data`](https://github.com/explosion/spacy-lookups-data) +> directly. + +- If you're training new models, you'll want to install the package + [`spacy-lookups-data`](https://github.com/explosion/spacy-lookups-data), + which now includes both the lemmatization tables (as in v2.2) and the + normalization tables (new in v2.3). If you're using pretrained models, + **nothing changes**, because the relevant tables are included in the model + packages. +- Due to the updated Universal Dependencies training data, the fine-grained + part-of-speech tags will change for many provided language models. The + coarse-grained part-of-speech tagset remains the same, but the mapping from + particular fine-grained to coarse-grained tags may show minor differences. +- For French, Italian, Portuguese and Spanish, the fine-grained part-of-speech + tagsets contain new merged tags related to contracted forms, such as + `ADP_DET` for French `"au"`, which maps to UPOS `ADP` based on the head + `"à"`. This increases the accuracy of the models by improving the alignment + between spaCy's tokenization and Universal Dependencies multi-word tokens + used for contractions. + +### Migrating from spaCy 2.2 {#migrating} + +#### Tokenizer settings + +In spaCy v2.2.2-v2.2.4, there was a change to the precedence of `token_match` +that gave prefixes and suffixes priority over `token_match`, which caused +problems for many custom tokenizer configurations. This has been reverted in +v2.3 so that `token_match` has priority over prefixes and suffixes as in v2.2.1 +and earlier versions. + +A new tokenizer setting `url_match` has been introduced in v2.3.0 to handle +cases like URLs where the tokenizer should remove prefixes and suffixes (e.g., +a comma at the end of a URL) before applying the match. See the full [tokenizer +documentation](/usage/linguistic-features#tokenization) and try out +[`nlp.tokenizer.explain()`](/usage/linguistic-features#tokenizer-debug) when +debugging your tokenizer configuration. + +#### Warnings configuration + +spaCy's custom warnings have been replaced with native python +[`warnings`](https://docs.python.org/3/library/warnings.html). Instead of +setting `SPACY_WARNING_IGNORE`, use the [warnings +filters](https://docs.python.org/3/library/warnings.html#the-warnings-filter) +to manage warnings. + +#### Normalization tables + +The normalization tables have moved from the language data in +[`spacy/lang`](https://github.com/explosion/spaCy/tree/master/spacy/lang) to +the package +[`spacy-lookups-data`](https://github.com/explosion/spacy-lookups-data). If +you're adding data for a new language, the normalization table should be added +to `spacy-lookups-data`. See [adding norm +exceptions](/usage/adding-languages#norm-exceptions). + +#### Probability and cluster features + +> #### Load and save extra prob lookups table +> +> ```python +> from spacy.lang.en import English +> nlp = English() +> doc = nlp("the") +> print(doc[0].prob) # lazily loads extra prob table +> nlp.to_disk("/path/to/model") # includes prob table +> ``` + +The `Token.prob` and `Token.cluster` features, which are no longer used by the +core pipeline components as of spaCy v2, are no longer provided in the +pretrained models to reduce the model size. To keep these features available +for users relying on them, the `prob` and `cluster` features for the most +frequent 1M tokens have been moved to +[`spacy-lookups-data`](https://github.com/explosion/spacy-lookups-data) as +`extra` features for the relevant languages (English, German, Greek and +Spanish). + +The extra tables are loaded lazily, so if you have `spacy-lookups-data` +installed and your code accesses `Token.prob`, the full table is loaded into +the model vocab, which will take a few seconds on initial loading. When you +save this model after loading the `prob` table, the full `prob` table will be +saved as part of the model vocab. + +If you'd like to include custom `cluster`, `prob`, or `sentiment` tables as +part of a new model, add the data to +[`spacy-lookups-data`](https://github.com/explosion/spacy-lookups-data) under +the entry point `lg_extra`, e.g. `en_extra` for English. Alternatively, you can +initialize your [`Vocab`](/api/vocab) with the `lookups_extra` argument with a +[`Lookups`](/api/lookups) object that includes the tables `lexeme_cluster`, +`lexeme_prob`, `lexeme_sentiment` or `lexeme_settings`. `lexeme_settings` is +currently only used to provide a custom `oov_prob`. See examples in the [`data` +directory](https://github.com/explosion/spacy-lookups-data/tree/master/spacy_lookups_data/data) +in `spacy-lookups-data`. + +#### Initializing new models without extra lookups tables + +When you initialize a new model with [`spacy init-model`](/api/cli#init-model), +the `prob` table from `spacy-lookups-data` may be loaded as part of the +initialization. If you'd like to omit this extra data as in spaCy's provided +v2.3 models, use the new flag `--omit-extra-lookups`. diff --git a/website/meta/languages.json b/website/meta/languages.json index 41c1bce7f..facfc3541 100644 --- a/website/meta/languages.json +++ b/website/meta/languages.json @@ -1,5 +1,35 @@ { "languages": [ + { + "code": "zh", + "name": "Chinese", + "models": ["zh_core_web_sm", "zh_core_web_md", "zh_core_web_lg"], + "dependencies": [ + { + "name": "Jieba", + "url": "https://github.com/fxsjy/jieba" + }, + { + "name": "PKUSeg", + "url": "https://github.com/lancopku/PKUSeg-python" + } + ], + "has_examples": true + }, + { + "code": "da", + "name": "Danish", + "example": "Dette er en sætning.", + "has_examples": true, + "models": ["da_core_news_sm", "da_core_news_md", "da_core_news_lg"] + }, + { + "code": "nl", + "name": "Dutch", + "models": ["nl_core_news_sm", "nl_core_news_md", "nl_core_news_lg"], + "example": "Dit is een zin.", + "has_examples": true + }, { "code": "en", "name": "English", @@ -14,68 +44,91 @@ "example": "This is a sentence.", "has_examples": true }, + { + "code": "fr", + "name": "French", + "models": ["fr_core_news_sm", "fr_core_news_md", "fr_core_news_lg"], + "example": "C'est une phrase.", + "has_examples": true + }, { "code": "de", "name": "German", -
