PHP Real-time Personalized Recommendation Technology Implementation

With the continuous development of e-commerce, more and more companies are beginning to pay attention to user experience, and personalized recommendations have begun to become what major e-commerce platforms are competing to study. One of the technologies. Personalized recommendations can improve user satisfaction, increase product sales, and also save platform promotion costs. Therefore, major e-commerce platforms are actively trying personalized recommendation technology and have achieved certain results.

This article will introduce how to use PHP to implement real-time personalized recommendation technology, thereby improving user satisfaction and platform marketing effects.

1. The concept and function of personalized recommendation

Personalized recommendation is to recommend relevant content to users based on their behavior, interests, history and other personalized information. Its core idea is to put users at the center and provide products and services that match users' interests by exploring their needs.

In e-commerce platforms, personalized recommendations can provide users with products and services that are more relevant to their interests, increasing users’ shopping experience and satisfaction; at the same time, it can also increase the platform’s sales volume and conversion rate. , increase user stickiness and platform competitiveness.

2. The principle of PHP to implement personalized recommendations

The main steps of PHP to implement personalized recommendations are as follows:

1. Data collection and processing

In e-commerce platforms, data such as user behavior, interests, and historical records are very important information, and these data need to be collected and processed. Commonly used collection methods include log collection, data capture, etc., and processing methods include data cleaning, filtering, and sorting.

2. Feature Engineering and Modeling

Feature engineering mainly extracts and processes features of the collected data to obtain feature vectors that can reflect user behavior and interests. Modeling is to establish a personalized recommendation algorithm model based on information such as feature vectors and user historical behaviors to recommend users.

3. Recommended data storage and update

Users’ interests and needs are constantly changing, so the storage and update of recommended data is also a very critical step. Commonly used storage methods include cache storage, database storage, etc., and update methods include scheduled update and real-time update.

4. Recommended results display

The display of recommended results is the last step of personalized recommendations. The quality of the display effect will directly affect user satisfaction. Commonly used display methods include page recommendations, email recommendations, SMS recommendations, etc. The design and optimization of the display interface is one of the important factors in improving user satisfaction.

3. Commonly used personalized recommendation algorithms

1. Collaborative filtering algorithm

The collaborative filtering algorithm is the most commonly used algorithm in personalized recommendations. The main idea is to use behavioral similarities between users to recommend target users. Commonly used collaborative filtering algorithms include user-based collaborative filtering algorithm and item-based collaborative filtering algorithm.

2. Content-based recommendation algorithm

The content-based recommendation algorithm makes personalized recommendations to users based on the attributes and characteristics of items. For two items, if their attributes and characteristics are similar, there is similarity between them and recommendations can be made based on the similarity.

3. Hybrid recommendation algorithm

The hybrid recommendation algorithm combines multiple algorithms to obtain more accurate and comprehensive recommendation results. For example, combining the collaborative filtering algorithm with the content-based recommendation algorithm can make full use of the advantages of the two algorithms and avoid their shortcomings.

4. Things to note when implementing personalized recommendations

1. High data quality requirements

The effect of personalized recommendations is directly affected by the quality of the collected data quality. Therefore, when making personalized recommendations, you need to pay attention to the quality of the data to prevent the occurrence of noisy data or erroneous data, which will affect the recommendation effect.

2. Selection and optimization of algorithms

According to different user groups and business scenarios, it is necessary to select appropriate personalized recommendation algorithms, optimize and adjust the algorithms, and improve Recommended for accuracy and effectiveness.

3. User experience of recommendation display

The ultimate goal of personalized recommendation is to improve user experience and satisfaction, so when recommending display, you need to pay attention to the user’s experience and habits. Provide concise and clear recommendation results to avoid interfering with users' browsing and shopping experience.

5. Summary

Personalized recommendation technology is a very important technology in e-commerce platforms, which can effectively improve user satisfaction and platform marketing effects. Using PHP to implement personalized recommendation technology can improve the recommendation effect and user experience, and increase the competitiveness and market share of the platform through good data collection, algorithm modeling and recommendation result display.
