In this section, we will tell you about successful projects implemented on the Toloka platform.
Collecting a dataset
The benefit of the Toloka crowdsourcing platform is that the requester can collect a dataset while spending a minimum amount of time and money.
- Protecting biometric data
The company ID R&D collected a dataset that let them build algorithms to protect their data from malicious attacks.
SMS, passwords, and codes don't guarantee 100% protection against attackers. ID R&D develops security systems based on voice, facial, and behavioral recognition. Using Toloka, the company collected a dataset of 112,000 sample photos and videos with people's faces.
- Dataset in five weeks
Roman Kutsev, the founder of Trainingdata.ru, created a dataset of more than 10,000 images using a chatbot and Toloka.
The dataset is based on photos of users and their description by the chatbot. This dataset might be useful for online dating platforms, because it lets the algorithms select suitable matches for specific users more accurately.
How it works:
- The user uploads their photo to the chatbot.
- After a while, the bot gives the user a detailed review.
The owners of the bot transmit the image to Toloka, where performers describe the characteristics of the person. Within five weeks, Roman managed to collect a dataset of more than 10,000 images.
- How to train artificial intelligence to understand the interlocutor
Sberbank trained the Event2Mind model to recognize the Russian language. After collecting the data for labeling, the Sberbank team used Toloka to create a dataset. This dataset was used for training the Event2Mind model.
- Dataset for 75 dollars
Neatsy's team was developing an app for ordering shoes online. The team collected and labeled 50,000 photos of feet of different sizes to teach the algorithm to automatically build a 3D model of a human foot and determine its size.
For this purpose, the company used Toloka. By using task decomposition, the team collected a dataset in five days, spending $75.
Tens of thousands of performers are active in Toloka every day. Requesters can quickly run mass surveys with a minimal budget.
- Crowdsourcing and logo changes
The “Zenith” bank demonstrated an example of successful logo change. Using a focus group, the bank created two versions of their logo.
To make their final conclusions, they decided to run a survey among their target audience. With Toloka, they managed to collect the necessary number of filled out forms within just a few hours. Based on the data from the forms, the bank chose the logo that was more memorable for the audience.
- How to update an app icon
Yandex showed an example of how to update an app icon without losing its recognizability.
Using Toloka, the company compared how long it took performers to find the classic icon and the new icon on their phone screens. The performers needed more time to find the new icon.
This prompted the company to implement the changes gradually, only slightly changing the icon at different project stages. With such an approach, they managed to achieve a similar result.
- Which supermarkets people like
Digital Guru analyzed which supermarkets are preferred by people. For this purpose, the company identified the most popular subjects in user reviews. They analyzed more than 75,000 reviews.
To analyze such a huge number of reviews, they decided to use Toloka. Several thousand performers analyzed the reviews. As a result of the analysis, two categories were identified. Based on the categories, the company created a table of the “best” and “worst” supermarkets.
In our blog, we regularly publish successful projects from our requesters, post useful tutorials, and inform you about new features in Toloka.
