UK Educational Institution Case Study

Empowering an Educational Institution in the UK with Precise Data Annotation Solutions

Client’s Background

The client is a distinguished educational institution based in the United Kingdom with a strong commitment to sustainability and research in this domain. Their focus is on reading and analyzing corporate sustainability reports, extracting relevant initiatives, and categorizing them according to a proprietary methodology. Mobilunity-BPO was engaged to provide a customized solution for their specific needs.


Client’s Problem

The client of Mobilunity-BPO, an educational institution based in the UK, sought data annotators with a strong interest in sustainable development and business. The project involved reading content from annual corporate sustainability reports, extracting information about sustainability initiatives, and categorizing them using an internal methodology. With a monthly volume of around 1 million words, the project necessitated the participation of four part-time annotators.


Project Challenge

The main challenge in this project stemmed from the ambiguity of the test task, which could lead to varying interpretations of the text. As a result, only 16% of the initially selected candidates met the criteria, resulting in a relatively low success rate for tasks of this nature. Nonetheless, our extensive pool of pre-screened annotators enabled us to adjust and provide the required number of specialists with the necessary skills.

Precise Annotator Selection

Our process began with a thorough pre-selection of 50 annotators, all of whom had a solid background in text annotation and an upper-intermediate level of English proficiency. This step was instrumental in ensuring our team possessed the necessary skills for the project.

Test Task Evaluation

Each annotator received a test task detailed by the client, and based on their performance, we shortlisted eight final candidates. However, given the task's inherent ambiguity, we recognized the need for a new approach.
