Data Collection Methods
Rendering synthetic data
Creating data based on specific parameters to model non-existent scenarios and train models without the risk of violating personal data handling rules.
Parsing and web scraping
An automated process for collecting and sorting data with specific parameters and defined attributes. This involves finding the necessary data on websites, forums, portals, online stores, etc., using parsers developed by us.
Crowdsourcing
Collection of data from a wide audience. Allows for obtaining diverse and up-to-date data for training models
Selecting open source datasets
Searching, filtering, and preparing data from open sources and data marketplaces according to technical specifications.
Data Collection Stages
Collection
Selecting appropriate tools and methods for data search according to the technical specifications and business goals.
Cleaning
Structuring and classifying the data by specified attributes to create a high-quality dataset and train the neural network on clean data.
Preparation
Preparing the dataset and metadata in the requested format. Transferring exclusive usage rights and signing all closing documents.
Augmentation
Generating data based on existing datasets using various distortion techniques (shape, color, tilt, etc.), and adding or mixing objects.
Types of Data
Text
We collect text data from various sources, including social networks, blogs, and crowdsourcing platforms. Collecting texts in different languages allows us to cover a wide range of topics and stylistic directions.
Images
Collecting images from open sources and through crowdsourcing platforms. We engage users to create unique images, which helps address a wide range of tasks effectively.
Video
Obtaining unique video recordings needed for specialized projects such as motion analysis, object tracking, or other complex tasks requiring detailed video surveillance.
Lidar
Collecting images from open sources and through crowdsourcing platforms. We engage users to create unique images, which helps address a wide range of tasks effectively.
