Assessing cognitive ability

A non-transitory computer-readable medium having instructions stored thereon, which when executed by a processing device, cause the processing device to perform operations comprising:

• receiving first cognitive ability levels for first persons, wherein the first cognitive ability levels represent assessments of the first persons within a model of cognitive abilities;
• receiving first user generated online data of the first persons;
• extracting first values for one or more types of features from the first user generated online data;
• comparing, by the processing device, the extracted first values to the received first cognitive ability levels to identify relationships between the types of features and the received first cognitive ability levels;
• and
• storing the relationships between the types of features and the received first cognitive ability levels in a storage device.

A system comprising:

• one or more interfaces to receive first cognitive ability levels and first user generated online data for first persons, wherein the first cognitive ability levels represent assessments of the first persons within a model of cognitive abilities;
• one or more processing devices to extract first values for one or more types of features from the first user generated online data, compare the extracted first values to the received first cognitive ability levels to identify relationships between the types of features and the received first cognitive ability levels;
• and
• one or more storage devices to store the relationships between the types of features and the received first cognitive ability levels.
