Label Efficiently with a Text Annotation Software

[1]

Label Efficiently with a Text Annotation Software

Leverage Kili Technology’s text annotation tools to create powerful text-based training datasets easily. Annotate all text-based assets (emails, transcripts, news articles, documentation, etc.) using intent classification, named entity recognition, and relation tasks. Use our powerful labeling queue to prioritize and assign text annotation tasks to specific labelers and reviewers and add validation rules to have their work automatically checked. Finally, run your custom model on the fresh dataset and generate model-based predictions to further accelerate labeling and boost quality.

Generate High Quality Text Annotation

[2]

Generate High Quality Text Annotation

Identify the right data to annotate to maximize your model's performance. Streamline collaboration between labelers, reviewers, and MLEs to quickly iterate on your text annotation projects. Minimize inconsistencies in dataset quality by providing continuous feedback. Use our advanced quality metrics to quantify quality and easily pinpoint assets or labelers with low metrics. Leverage our automated QA scripts to programmatically spot errors in your text annotation and use error detection models to improve overall performance.

Integrate Text Annotation in Your ML Stack

[3]

Integrate Text Annotation in Your ML Stack

Safely import data from remote storage (Amazon, Google, or Microsoft cloud storage), track changes to your data, version your projects, and then easily export your labeled text dataset to a preferred format (YOLO, Pascal VOC, Kili, etc.).

Easily manage the entire training data lifecycle of your ML project in Kili. Use  specific access levels for your organization members and assign predefined roles (admin, manager, reviewer, labeler) in labeling projects.

Leverage active learning to pre-generate labels. Create a feedback loop between your model and your text annotation project. Use Kili’s Python SDK and API to integrate with all machine learning stacks.

Frequent questions

How do you annotate text?
Annotating text on Kili Technology is simple. Upload your text asset and classify your text, use named entity recognition to identify objects, and label using bounding boxes.
What is a PDF annotation tool?
A PDF annotation tool, like Kili Technology, is a tool that allows the detection and extraction of key information in a PDF document.
What is an annotation tool?
Kili Technology is a global annotation tool that supports the PDF format, but can also help on image, video, audio and text annotation.
What are the applied use cases of text annotation.
Text annotation is an essential step in the training of your ML model, and can be used to build chatbots, bank statement, emails or invoices automatic processes. The goal is to automate existing low-value tasks, and allow workers to be more productive and focus on high-value tasks.
What are best programming tools to be used for text annotation (NLP)?
The best programming tools for NLP are Propagate for Named Entity Recognition (NER), Python for Regex, and Snorkel if you’re looking for open source.
How do I annotate text quickly?
xt, you can use rule based labeling, then manual labeling, then ML based labeling.
What is a good way to annotate text in a contract?
The best way to annotate text in a contract (text or pdf) is to extract important entities from the text with Named Entity Recognition (NER), and link entities that are connected to each other with Named Entity Linking (NEL). To label signatures, stamps, or logos, you can use bounding boxes. bbox for signature & stamps. To do this, use a labeling platform.
What are good annotation tools for chatbot data?
SAP, Google, IBM have solid chatbot building tools. Labeling tools like Kili Technology are also powerful options because of the management of rich text, classification for intent, named entity recognition (NER) and Named Entity Relation (NEL).
What are the most common text annotation formats?
For Named Entity Recognition, the most common format is IOB. For classification and relations, the best formats to use are binary or JSON.
