Today we are going to talk about user portraits.

What is a user portrait?

A passage from Baidu Baike

User portrait, also known as user role, has been widely used in various fields as an effective tool for drawing target users, connecting users' demands and design direction.

I think that might be a little ill-organized.

User roles

User Role (User roles) are more likely to describe the Role of users in various systems, such as oa, the Role of each person is different, have the menu, fuck do, such as page access is different also, think of a trill on jokes, say not to use Meituan take-away, became a rider registration for half an hour, for delivery system, Shop, rider, and consumer are three different roles, each of which has different business, sees different things and performs different operations when entering the system. Therefore, user-role focuses on solving the problem that different business scenarios and permissions of different users in the business system are different.

User Profile

User-profile, on the other hand, tends to describe the same type of users from different dimensions. Take take-out as an example. Take-out system subdivides and imagizes consumer users by taking advantage of consumers' hobbies and consumption level, designs crowd portraits, makes some recommendations and data analysis, etc. For example, for consumers who love hot pot, put hot pot take-out in front of the list on the home page, and make a member points system through consumption data. However, comparing different types of users does not have much business significance. For example, consumers and riders are rarely compared. Therefore, user-profile focuses on describing the same type of users from different dimensions.

Endorsement, pick a paragraph from the book said better

User portrait is a kind of carrier which can combine qualitative and quantitative methods.

Qualitative method, through the user's life situation, use of the scene, the user's mind to analyze the nature and characteristics of the user to make abstract and summary; Quantization can make precise statistical analysis and calculation of features to obtain a more accurate understanding of users, which is convenient to realize the discovery and burst of core users on the basis of numerical ranking.

Conclusion under

User profiles are used to help us get to know our users. ### The data flow to build user portraits or take the takeout system as an example, what is the general data flow to build consumer user portraits like

Notice the two words qualitative and quantitative mentioned above


Qualitative can also commonly called dimensions, that is, we go to describe a user's point of view, dimension is our designer, what dimensions are used to describe the user, the first may be the factors such as our experience, rational analysis, intuitive let us decide what kind of dimension, how many dimensions to describe the user, to build the user portraits, portraits the user to the computer, We designers play a very important role in the process of making computers read users' images and use them to solve some business problems, and iterating our designs through the results (this is also one of the reasons why I think our work will not be replaced by AI).


On the basis of determining the dimensions, we can do fine statistical analysis and calculation of features, such work is called the computer to do, to use effect oriented, to guide quantization.

Application domain of user portrait

User profiles are generally used in the following areas

The user portrait here gives you a simple chat, in the back will talk about the specific construction of the scheme, welcome everyone to exchange, point out some mistakes in the article, let me deepen my understanding, I wish you no bugs, thank you!
