## Package naming conventions {id="conventions"}
In general, spaCy expects all pipeline packages to follow the naming convention
of `[lang]\_[name]`. For spaCy's pipelines, we also chose to divide the name
into three components:
of `[lang]_[name]`. For spaCy's pipelines, we also chose to divide the name into

`textcat` or `textcat_multilabel` model - ensure that values are `0.0` or `1.0`
as explained in the [docs](/api/textcategorizer#assigned-attributes).
### Using the default knowledge base
As `KnowledgeBase` is now an abstract class, you should call the constructor of
the new `InMemoryLookupKB` instead when you want to use spaCy's default KB
implementation:
```diff
- kb = KnowledgeBase()
+ kb = InMemoryLookupKB()
```
If you've written a custom KB that inherits from `KnowledgeBase`, you'll need to
implement its abstract methods, or alternatively inherit from `InMemoryLookupKB`
instead.
