|

| Our popular dependency and named entity visualizers are now an official
|
||||
| part of the spaCy library! displaCy can run a simple web server, or
|
||||
| generate raw HTML markup or SVG files to be exported. You can pass in one
|
||||
| or more docs, and customise the style. displaCy also auto-detects whether
|
||||
| you're running #[+a("https://jupyter.org") Jupyter] and will render the
|
||||
| visualizations in your notebook.

|

| The improved #[code spacy.load] makes loading models easier and more
|

| transparent. You can load a model by supplying its
|

| #[+a("/docs/usage/models#usage") shortcut link], the name of an installed
|
||||
| #[+a("/docs/usage/saving-loading#generating") model package], a unicode
|

|

| argument in this order. The #[code path] keyword argument is now deprecated.

p
|
||||
| The #[code Language] class to initialise will be determined based on the
|

| model's settings. If no model is found, spaCy will let you know and won't
|

| just return an empty #[code Language] object anymore. If you want a blank
|
||||
| language, you can always import the class directly, e.g.
|
||||
| #[code from spacy.lang.en import English].

p
|
||||
| spaCy now supports simple lookup-based lemmatization. The data is stored
|
||||
| in a dictionary mapping a string to its lemma. To determine a token's
|
||||
| lemma, spaCy simply looks it up in the table. The lookup lemmatizer can
|
||||
| be imported from #[code spacy.lemmatizerlookup]. It's initialised with
|
||||
| the lookup table, and should be returned by the #[code create_lemmatizer]
|
||||
| classmethod of the language's defaults.

+h(3, "features-matcher") Revised matcher API

|
||||
[{LOWER: 'hello'}, {LOWER: 'world'}])
|
||||
|
||||
p
|
||||
| Patterns can now be added to the matcher by calling
|
||||
| #[+api("matcher-add") #[code matcher.add()]] with a match ID, an optional
|
||||
| callback function to be invoked on each match, and one or more patterns.
|
||||
| This allows you to write powerful, pattern-specific logic using only one
|
||||
| matcher. For example, you might only want to merge some entity types,
|
||||
| and set custom flags for other matched patterns.
