For high-precision tasks, such as medical development and natural language processing, entrust difficult annotations to Human Science.

Human Science has been involved in AI development projects for many companies, including GAFAM.
Our annotation services have been utilized in various fields, such as natural language processing, medical support, autonomous driving development, and architecture.
We can meet the challenges faced by our customers through various operation methods: remote, on-site, resident stationing at the customer's environment, or whatever the project needs.
We implement thorough security measures through the selection of tools, education of workers, and build-out of work environments.

Translation, Documentation, and Annotation Achievements

Strengths of Human ScienceFeatures

  • Trained project managers educate annotators.
    That's how we create high-quality teaching data.
    When starting a project using our annotation outsourcing service, the project manager first familiarizes themself with the work requirements. By having an experienced project manager educate the annotators before starting the work, we enable high-precision annotation. In cases where online familiarization is deemed difficult based on the nature of the work, we also provide support by stationing the project manager at the customer's location for training and other needs.
  • Annotation tools with top-notch security
    used by the largest domestic automakers.
    One of the annotation tools we use is AnnoFab. This tool has also been adopted by Japan's top automobile manufacturers and has excellent security. It supports AWS and other customer-side cloud services and puts restrictions on IP addresses, ensuring a robust security system.
  • Resource management without crowdsourcing.
    We can also provide options like the use of our secure rooms and resident support at customer locations.
    For customers who want to avoid using crowdsourcing for security reasons, please rest assured. At Human Science, reliable annotators contracted directly by our company will handle the work. For on-site projects, we can also provide the use of our secure rooms with ISMS certification or resident support at the customer's location.
  • Reduce communication costs with direct support in English.
    Do you need communication in English? Don't worry. We can provide direct support. Compared to translation or interpretation orders from other companies, you can expect significant cost advantages.
  • Achieve excellent cost performance with an offshore system.
    Our company conducts offshore annotation services in Vietnam. By utilizing overseas resources under our contract, we provide high-quality annotation services comparable to other domestic offerings, but at a lower cost. Even for offshore projects, we still handle management tasks, such as customer interfacing and quality control, in Japan.
