Why HN links it

HN readers link Label Studio, an open-source data labelling tool with a playground, for annotating training data for NLP and machine learning projects. The comments are mostly about the tool itself.

Summarised by Claude from a sample of 5 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

Multi-modal data labeling and annotation platform for agent traces, LLM evals, RLHF, computer vision, document AI, NLP, audio transcription, and more.

  1. Heartex / Label Studio | Senior FrontEnd Engineer / FullStack Engineer | Full-Time | Remote Hey there, Michael here, one of the founders. We're building a data management platform for Machine Learning. As a part of the core engineering team, you'll be working on our open-source data labeling tool https://labelstud.io/ as well as a commercial offering. There is a lot of exciting work! I'd say that this is nowadays a…

  3. Thanks! Comparison between news outlets is on the radar, once I improve the tool based on feedback from this Show HN. My backend uses spaCy (NER/NLP), textacy [1] for extracting subject-verb-object triples, and coreferee [2] for coreference resolution. I did build a custom spaCy model for which I manually annotated over 700 crash-related news articles in Label Studio [3]. This custom model identifies counterfactuals…

  5. This reminded me of a great OSS tool I discovered the other data for data labelling. It is called Label Studio ( https://labelstud.io/playground/ ) and support quite a variety of different task formats. Works well Disclaimer: No affiliation, only sharing for those who are curious

  9. We recently open sourced an agent framework [1] for automating data processing and labeling where the agent's prompt is refined trough iterations with the environment and then asking to an LLM to revise the prompt according to its performance (i.e. automatic prompt tuning). We tested it on the Math reasoning dataset GSM8k and where able to improve the baseline accuracy (GPT4) by 45% -> 74% using 25 labeled examples…

  11. I’ve had good results in the past by fine tuning YOLO for image classification and object detection within images, you can find a rough guide here on how to create a good training dataset and such [0] [1] YMMV though, ultimately accuracy is going to depend on the quality of the labelled data and your use case There might be models better suited to your specific needs too, but ultimately you’re always going to need t…

  13. Huh? I wrote my own system for classifying a stream of texts in Python, I might Open Source it one of these days but I have to get it to the point where it is modular enough that I can customize it to do the particular things I want without subjecting people to my whims... I use it every day and I'm not afraid to demo it because it is rock solid. My understanding is that my system would not be hard to adapt to work…
