Paragraphs

Now you can label structured text in simple json format. Introducing Paragraphs!
It requires array of phrases, defined as object with two required fields:
first one for author (set by nameKey, "author" by default) and second one for text itself
(set by textKey, "text" by default). For better appearance use layout="dialogue".

Audio pre-listening

Also you can attach audio for these phrases by audioUrl.
It uses optional fields in phrases' objects: start and end/duration in seconds,
linking phrases with according part of audio.

Taxonomy

<Taxonomy> is a new control tag wrapper that allows you to build a nested choices structure - a multi-class classification tree. The usage is quite intuitive:

  <Taxonomy name="" toName="text">
    <Choice value="Archaea" />
    <Choice value="Bacteria" />
    <Choice value="Eukarya">
      <Choice value="Human" />
      <Choice value="Oppossum" />
      <Choice value="Extraterrestial" />
    </Choice>
  </Taxonomy>

Learn more by playing with Text taxonomy template on Setup page!

Undo/Redo/Reset

Now you can see the current state of your actions history — is it possible to undo/redo.
Also reset can be undone.
Both cmd+z and ctrl+z are working now.

TextArea regions

Improve text comments, especially multiline ones — they appears much better than before,
you can add them by shift+enter or cancel editing by escape.
Also you can delete classification comments with trash bin icon next to it.
And they will back to Regions list soon.

• Docs updates

Release 0.7.5.post0

We put a big effort to rewrite some parts of the labeling engine for easier and better work with results, deserialization, an inner structure and so on. That led us to faster initialization (but we have a lot of space for improvements), more predictable regions operations, more stable per-region labeling, non-breaking region removal.

Features

• Relations visualizations
• Nested labeling improvements
• Granularity fixes - now you can enable granularity per label
• New deserialization mechanics for LSF
• LSF faster initialization,
• More predictable regions operations
• More stable per-region labeling
• Non-breaking region removal

Improvements

• Show errors about content loading and CORS problems
• Detailed logs from ML backend on ML page
• Task navigation improvements with hotkeys on the tasks page
• Minimum formatting of completed_at (@TTouka)
• Maintain ordering in source.json and task.json for sequential sampling (@theconsummatedhruv)
• Move external fonts to LS
• Improving documentation clarity and readability
• Add ML predictions on the tasks page
• Table tag support on import and its example
• Previews for audio and texts on the tasks page
• Don't keep premade predictions in completion + Keep premade predictions if we can't get fresh (@hepaajan)
• Support hostname environment variable to docker
• COCO export support for segmentation (@vkhizanov)

Fixes

• Fixed dates in non-Chromium browsers
• Don't stretch out text object with long lines
• Don't save broken regions (polygons, brushes)
• Fixed per-region audio labeling with predictions
• Update s3 signature version to s3v4 to support more AWS regions (@wdvr)
• Fixes for task validation in cloud storages
• Update pip and six packages to avoid fails while LS install
• Fix storage paths with trailing slashes
• Fix Project.next_task to sort task IDs for "sequential" sampling (@k4200)

Release 0.7.4

Features

• quickview for task page
• WSGIServer support by @k4200
• https with ssl support by @abduhbm
• project setup api added
• brush RLE converter for export (label-studio-converters module)

Improvements

• significant speed up of task importing with @lightforever
• significant speed up of next task & tasks page

Fixes

• correct ordering for skip
• relative url links for pages and api
• encoding fixes
• allow one label in labeling config validation
• misspelling errors fixes by @Necmttn
• ML backend loads previously trained model before starting the new one

Label Studio Frontend

• we released BrushLabels a while ago, but they were not ready for production use and had some harmful problems. So now they are all fixed. Now they are stable after submit or resize and won't lose your labeling.
• fixed problems with completions created from predictions — they won't break the app from now.
• clickable href links
• previously we used to disable all links in your HyperText documents to protect you from leaving the labeling suddenly. But now if you really need to follow these links you can use . Anyway all links will open by ctrl/cmd+click.
• now you can hide regions for easier labeling if you have them a lot. Just use the eye button in regions list. Works only for images.
• other minor bugs
