Integrating tagtog and spaCy: a simple example

This tutorial uses the spaCy library to automatically generate NER (Named-Entity Recognition) annotations and display these annotations directly in tagtog.

Build powerful annotation layouts with tagtog blocks

As part of the flavored Markdown used in tagtog, you can create blocks with custom styles/layout. As we all know, annotating data can be a tedious task, and a more attractive content can be key to keep your team engaged. Using Markdown you can use the new tagtog blocks to build a customized annotation layout for your project! E.g. question answering datasets, chatbot training, tweets, etc.

The adjudication process in collaborative annotation

If multiple annotators work on the same data, as a result, there are multiple annotation versions. We define adjudication as the process to resolve inconsistencies among these versions before a version is promoted to the gold standard. This process is manual, semi-automatic or automatic. Learn the differences and when to use each of them.

Poor Inter-Annotator Agreement: what to do?

There may be several reasons why your annotators do not agree on the annotation tasks. It is important to mitigate these risks as soon as possible by identifying the causes. Discover how to prevent a low Inter-Annotator Agreement.

Automatic adjudication based on the inter-annotator agreement

When multiple annotators produce annotations for the same data, tagtog chooses the annotations from the available-best annotator for each annotation task. Check out step by step how to setup this process.

How to rank & review your annotators

Some useful tips and suggestions that may be useful for anyone who is managing a team of annotators. tagtog allows users to filter documents based on whether a given user has confirmed them (or any user has confirmed them). This feature, despite it may not look like such a big deal, it can be used for many different things. In this post we discuss some of the applications 🚀.
