TextLab uses its technology to dynamically profile users within various contexts in order to identify which users are the most likely to respond to particular textual variants. The company uses machine-learning algorithms based on neural networks and closed-feedback-loop technology to continuously fine tune user profiles to better target users with the most effective text. TextLab uses a multistage personalization engine to create an exclusive textual profile of each user. Its technology automatically extracts textual and linguistic features based on the website or advertised content. With its ANN platform, TextLab creates a unique, dynamic profile for every user. Users are then grouped into clusters based on the proximity of their profiles within a specific context. TextLab is developed by TextArt Labs.
