A Scalable, Non-Intrusive Method for Deriving a User's Circadian Typology Based on Personality Traits

The circadian typology of a user explains how that individual performs at certain moments of the day . For example, people of a morning typology are more alert at that time of the day, so it is better for such people to engage in tasks requiring concentration or attention to details early in the morning (the converse applies for persons of an evening typology). This information can be valuable in a variety of contexts, such as:

Managers delegating tasks to employees at times of the day that would be most productive
Marketing departments contacting customers at those times of the day when people are more receptive to product

offerings.

Human resources departments interviewing people for security-sensitive jobs

Although there is prior art in computing circadian typologies [5], such work exploits a correlation between physiological data and circadian rhythms; therefore, such approaches are not practical for the examples listed above (e.g., a marketing department cannot realistically ask for biometric data for an entire organization's customer base).

A practical, scalable, and non-intrusive circadian typology calculator is needed. In particular, a circadian calculator needs to be suitable for each of the examples outlined above, as well as for a variety of systems and scenarios that would benefit from knowing the circadian typology of a user in a non-intrusive manner. Such a circadian calculator can be useful for:

Human resources personnel selection for security-sensitive job positions (i.e., evening or overnight working hours)

Marketing departments devising effective direct marketing strategies Project planning and task assignment Scheduling tasks demanding a high level of mental effort to the most favorable time of the day for a user
Aggregating content by classifying content as dense (such as a mathematical article) or light (such as entertainment

  news), a content aggregator could organize what kind of material should be presented to a user at a given time of the day
Planning travel such that if an itinerary segment demands driving, it can be done when the traveler is the most alert

The novel contribution is a method for non-intrusively deriving the circadian typology of a given user. The method derives a user's circadian typology by exploiting the correlations between psychologicaldata (i.e., the Big Five personality profile) and circadian rhythms. The personality profile for a user can be derived by the existing cognitive services using textual data such as a user's social media feed(s). The proposed method is practical and scalable, and computes circadian typologies based solely on a user's

In a preferred implementation, the method derives the circadian profile of an individual by exploiting correlations between circadian typology and personality traits. The...
