Question: When developing a dating app, how can we design a matching algorithm so that users of a certain gender receive matching suggestions first?
Answer: When designing the matching algorithm of a dating app, to give priority to users of a certain gender to obtain matching suggestions, you can consider the following aspects:
### Data collection and analysis
1. **User profile information**
-Collect user data in multiple dimensions, including basic information (age, gender, location), hobbies (such as music type, sports, movie preferences, etc.), lifestyle (whether you like to socialize, whether you travel frequently, etc.), personality characteristics (through simple personality test questionnaire results), etc.
-For example, hobbies can be refined to specific genres or activities, such as heavy metal genres in rock music, single-day short-distance routes in hiking, etc.
2. **Behavioral data**
-Record user behavior, such as login frequency, number of visits to other user information, residence time for different types of user information, behavior of sending and replying to messages, etc.
-For example, if a user often logs in to the app from 9pm to 11pm and browses a large number of user data of the same gender and similar age, this can be used as a basis for analyzing their preferences.
3. **Preference data**
-Users can set their own preferences, such as the gender, age range, distance range, etc. that they expect to match. These clear preferences are an important source of data.
-For example, a male user sets the expected matching female to be between the ages of 22 and 28, and the distance is within 10 kilometers, which provides a clear filter for the matching algorithm.
### Core design of matching algorithm
1. **Preliminary screening based on preference**
-For the gender (assuming male) that wants to give priority to matching suggestions, first conduct a preliminary screening based on their set preferences.
-For example, if male user A sets the expected matching female to be 20-25 years old and located within 5 kilometers, then the algorithm first filters out a list of users who are 20-25 years old and within 5 kilometers of User A's location from all female users.
2. **Calculation of matching interests and hobbies**
-Calculate the matching degree of users in terms of interests and hobbies after filtering. Each hobby dimension can be given a certain weight.
-For example, user A likes football and reading science fiction, user B likes basketball and reading science fiction, and User C likes badminton but not science fiction. Suppose the weight of football is 0.4, the weight of basketball is 0.3, the weight of badminton is 0.3, and the weight of basketball is 0.5. Then the degree of matching between user A and user B in terms of interests and hobbies is (0.4 + 0.5) = 0.9, and the degree of matching between user A and user C in terms of interests and hobbies is (0.4 + 0.5) = 0.9.(0.4 + 0.3 + 0.5 * 0) = 0.7。
- Sort the female users after the preliminary screening from high to low according to the matching degree of interests and hobbies.
3. **Behavioral data weighting**
-Weighted based on behavioral data. If a male user often browses a certain type of female user information, it means that he may have a higher interest in such women.
-For example, male user A has frequently browsed the profiles of female users who are 22-24 years old and like to travel in the last week, so for such female users, the weight can be appropriately increased when calculating the matching degree. Assuming that the normal interest matching degree is the basic value, for such women who are particularly concerned by User A, the interest matching degree can be multiplied by a coefficient of 1.2.
4. **Matching personality traits and values**
-Consider the matching of personality traits and values. Although it is relatively difficult to obtain data in this regard, a general assessment can be made through a simple personality test questionnaire filled out by the user.
-For example, suppose that the personality test divides personality into extroverted, introverted, optimistic, pessimistic and other dimensions. If male user A is extroverted and optimistic, then female users who are extroverted and optimistic will be given priority when matching. You can set a certain threshold for personality matching, and only female users who reach this threshold will enter the higher matching suggestion list.
5. **Comprehensive matching score calculation**
-Combining the above factors to calculate the comprehensive matching score of each female user and male user A.
- For example, comprehensive matching score = interest matching score * 0.6 + behavioral data weighted score * 0.3 + personality characteristics and values matching score * 0.1.
-Sort female users according to the comprehensive matching score, and the higher the score, the higher the ranking of female users, so as to provide priority matching suggestions for male users.
### Dynamic adjustment and optimization
1. **Real-time feedback and data updates**
-The application should be able to collect user feedback on the matching results in real time, such as whether it is interested in the matching object, whether it is willing to communicate further, etc.
-Based on user feedback, update the user's behavior data in a timely manner. For example, if a male user does not reply to a matching female, the message will be updated.
