Ask HN: How do you annotate your data?

Post by buckhx » Thu, Aug 01, 2019, 2:21 PM UTC

Hey HN,

I'm curious how folks annotate their data to be used in ML pipelines (NLP/Vision) and what their experiences have been. Production/applied examples with teams of annotators would be great.

From folks I've spoken with these seem to be the most common ways:

* Custom Solution * Prodigy * Dataturks * Lighttag

I'm curious if there are more latent examples leveraging your users such as Google's image captcha.

I built 2 annotation tools for the company I work for.

one is web based,

the other is a c++ app that can directly annotate videos.

the web based one is abandoned, because I found it is difficult to do frame level navigation.

Is there a reason you chose to build your own instead of using an off the shelf solution?
