The TEI converter is still in active development. If you need the latest version, clone the Text-Fabric repo and in its top-level directory run the command:

pip install -e .

12.0

12.1 (upcoming)

2023-09-??

New stuff

• In tf.convert.addnlp we can now extract more NLP information besides tokens and sentences: part-of-speech, morphological tagging, lemmatisation, named entity recognititon

• In the Text-Fabric browser there will be a new tab in the vertical sidebar: Annotate, which will give access to manual annotation tools. I'm developing the first one, a tool to annotate named entities efficiently.

  These tools will let you save your work as files on your own computer, maybe even feature files, so that you can explore the result by means of queries in the text-fabric browser as you go.

Fixes

• in the TEI converter.

12.0.6,7

2023-09-13

Trivial fix in code that exports the data from a job in the Text-Fabric browser. In the meanwhile there is unfinished business in the Annotate tab in the TF-browser, that will come into production in the upcoming 12.1 release.

The Chrome browser has an attractive feature that other browsers such as Safari lack: It supports the CSS property content-visibility. With this property you can prevent the browser to do the expensive rendering of content that is not visible on the screen. That makes it possible to load a lot of content in a single page without tripping up the browser. You also need the [IntersectionObserver API])https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API), but that is generally supported by browsers. With the help of that API you can restrict the binding of event listeners to elements that are visible on the screen.

So, you can open the Text-Fabric browser in Chrome by passing the option --chrome. But if Chrome is not installed, it will open in the default browser anyway. Also, when the opening of the browser fails somehow, the webserver is stopped.

12.0.5

2023-07-10

Fixed references to static files that still went to /server instead of /browser. This has to do with the new approach to the Text-Fabric browser.

12.0.0-4

2023-07-05

Simplification

• The Text-Fabric browser no longer works with a separate process that holds the TF corpus data. Instead, the webserver (flask) loads the corpus itself. This will restrict the usage of the TF browser to local-single-user scenarios.

• Text-Fabric no longer exposes the installation options [browser, pandas]

  pip install 'text-fabric[browser]' pip install 'text-fabric[pandas]'

  If you work with Pandas (like exporting to Pandas) you have to install it yourself:

  pip install pandas pyarrow

  The TF browser is always supported.

  The reason to have these distinct capabilities was that there are python libraries involved that do not install on the iPad. The simplification of the TF browser makes it possible to be no longer dependent on these modules.

  Hence, TF can be installed on the iPad, although the TF browser works is not working there yet. But the autoloading of data from GitHub/GitLab works.

Minor things

• Header. After loading a dataset, a header is shown with shows all kinds of information about the corpus. But so far, it did not show the TF app settings. Now they are included in the header. There are two kinds: the explicitly given settings and the derived and computed settings. The latter ones will be suppressed when loading a dataset in a Jupyter notebook, because these settings can become quite big. You can still get them with A.showContext(). In the TF browser they will be always included, you find it in the Corpus tab.
