Quality assurance FAQ

What is the difference between consensus and benchmark?

The Auto consensus tool is allows you to compare one the label of one member against the labels of other members to automatically calculate the overall consensus. You can configure the percentage of your dataset in a project that will be selected to be labeled more than once by distinct members. Because this calculation compares a labelers work to that of their peers, you can see which labelers are producing labels that tend not to agree with the majority. You can also track the consensus of your labeled dataset against entire labeling team to ensure high label quality. Poor consensus may also be an indicator for a need to clarify the ontology or classification questions in order to boost the consensus scores.

The Benchmark tool allows you to set a “gold standard” annotation and compare your labelers annotations against it. The benchmark tool works by interspersing data to be labeled, for which there is a benchmark label, to each person labeling. The accuracy score for each label is calculated based on its comparison to its respective benchmark.

Will other labelers see the data that I’m labeling?

If Auto Consensus is turned on and configured, yes. Otherwise, no.

Can I compare model-assisted predictions against human-made labels?

With Labelbox you can connect your machine learning model and compare your model’s performance against your team of labelers. To learn how to import model predictions to your project, click here.

Developer FAQ

Does Labelbox have an API?

Yes. All of the functionality offered in our application interface can also be programmatically configured with our GraphQL API. Access to the Labelbox API is included in the Pro and Enterprise tiers.

Labelbox also offers a Python API for those wishing to work with the API by using Python instead of by writing GraphQL queries.

If you are interested in learning more about API access and functionality, please contact sales at https://labelbox.com/sales.

How do I create an API key?

API Keys can only be created by Organization administrators. To read our documentation for setting up API keys, click here.

Importing & exporting data FAQ

I already have training data. Can I import it into Labelbox?

Whether you are uploading model-assisted predictions or human-labeled data, you can import your data with the “Import predictions” function of our API. To explore this functionality, please visit our docs page here.

Which label export formats does Labelbox support?

Your labeled data can be exported in JSON or CSV format, which should allow you to import it into any standard machine learning framework. Labelbox does not offer any direct export options for COCO or PASCAL VOC. Users may use the conversion scripts in this open source package to convert a JSON format to COCO or VOC format, however, the scripts in that open source package are no longer being actively maintained by Labelbox.

Does Labelbox work with on-premises data?

Labelbox works with source data hosted on-premises or on a private cloud. The source data is accessed directly from the client computer and is never shared by (or accessible to) Labelbox. Check out our on-premises documentation here.

Does Labelbox work with Cloud buckets data such as Amazon S3 or Google Cloud Storage?

Yes. To learn how to upload your data from these cloud sources, read through our documentation here.

Accessibility FAQ

Does Labelbox work in all countries?

Yes, unless your network has a restrictive firewall or you have internet connectivity issues. We currently only support the English language on our platform.

Do I need internet connection to use labelbox?

You must have internet connection to use Labelbox. We recommend either Google Chrome or Firefox as a web browser. Due to known compatibility issues, we do not recommend Internet Explorer or Safari.

Can I use Labelbox on a mobile device or iPad?

Privacy & security FAQ

How is data stored at rest?

Data is encrypted at rest using AES256.

What do we do with customer data?

We use each customer’s data to provide the services to that customer. We also use aggregated anonymized data that cannot be traced to any customer individually to improve our products and services.

How is data secured when outsourcing to the workforce?

The outsourced labeling team connects directly to a Labelbox project to label and review, but cannot access the data (including training data) directly. In addition, the workforce providers are Labelbox consultants bound by strict confidentiality provisions regarding your data.

What is the security practice of the labeling workforce?

Our Labelbox annotation services delivery center is SOC2 Type1 certified. All the work is done in a supervised environment by annotators who are employed by Labelbox’s labeling services consulting company. We don’t crowdsource and don’t work with any freelancers. We also don’t allow any remote logins from home.
