Big Data and AI in the E-commerce Industry

In today's digital age, the importance of leveraging big data and AI technologies cannot be understated. As an e-commerce giant, Alibaba has been at the forefront of utilizing these technologies to enhance its operations and provide better services to its customers. In this article, we will delve into two specific cases that highlight how big data and AI are being utilized in the e-commerce industry: the micro loan case and AI-powered image search.

2.1. The Micro Loan Case

One of the biggest challenges faced by banks when issuing loans to small and medium-sized enterprises (SMEs) is the lack of information about their operation status and creditworthiness. Traditionally, banks require guarantees such as property ownership to issue loans. However, most SMEs, especially those operating solely online, do not have physical assets to provide as collateral.

To tackle this problem, Alibaba's finance arm, Ant Financial, devised a solution using big data. As SMEs conduct their business transactions on Alibaba's platform, they generate a vast amount of data. Ant Financial leverages this data to assess the risk of issuing loans to SMEs. They developed the "3-1-0 Rule" — it takes three minutes to fill the loan application form, one Second for the system to approve or reject the application, with zero human interventions throughout the process.

With this data-driven approach, Ant Financial is able to process loan applications quickly and efficiently. The smallest loan amount processed is approximately $1,000, and the average cost to process a loan application is around $4. The default rate is less than 1%, showcasing the effectiveness of using big data for risk assessment in the micro loan case.

2.2. Leveraging Data for Risk Assessment

The core of Ant Financial's micro loan service application lies in its Big Data Platform, called MaxCompute. This platform acts as the central hub for processing and analyzing massive amounts of data. With over 3,000 data sources, both internal and external, MaxCompute enables the integration of diverse datasets.

Data scientists at Ant Financial deploy models and run compute jobs to process the huge amount of data, which amounts to approximately 20 petabytes per day. These models generate credit scores for every seller, allowing for accurate risk evaluation. The frontend system utilizes these credit scores to evaluate the risk associated with each seller.

The key advantage of MaxCompute lies in its scalability and cost-effectiveness. With its enormous computation power, MaxCompute can handle the large volume of data and perform complex computations efficiently. Additionally, it ensures data security, making it a robust and reliable platform for data processing.

AI and Image Search

Image search is a challenging problem for e-commerce platforms. Traditional keyword-based search often returns numerous results, making it difficult for consumers to find the exact product they are looking for. To overcome this issue, Alibaba's data scientists proposed an AI-powered solution: image search.

3.1. Challenges of Keyword-based Product Search

When users enter keywords into the search box, it often leads to an overwhelming number of results. Describing certain products accurately with words can be challenging. For example, it is difficult to describe a specific dress or a unique design flawlessly. This is where image search comes into play.

By allowing consumers to upload images of the desired product, Alibaba's image search system can accurately search for similar products. This approach is more intuitive and user-friendly, as a picture is worth a thousand words. However, building an image search system at Alibaba's Scale is no simple feat.

3.2. Implementing Image Search

Alibaba's image search solution utilizes its robust big data platform, MaxCompute, to process and analyze the vast image database. With over 1 billion images in its inventory and millions of new images uploaded daily, the Search Engine must handle a massive volume of data and produce accurate results within 100 milliseconds.

The architecture of the image search system follows a similar design to Alibaba's other big data projects. Data from various sources, including CCTV cameras and traffic lights control systems, is processed and integrated in MaxCompute. AI models are built on top of this platform, continuously improving the accuracy of the search results.

By leveraging the power of AI and big data, Alibaba's image search system provides an efficient and accurate way for consumers to find products that match their visual preferences. This technology has been adopted by reputable companies such as iconic to enhance their e-commerce platforms.

Alibaba Cloud's Design Principles

Alibaba Cloud follows a set of design principles to ensure the success of big data and AI projects. These principles cover the entire data lifecycle, from data injection to data visualization. By adhering to these principles, Alibaba Cloud has developed various solutions tailored to different vertical industries.

4.1. The Four Stages of Data Management

Alibaba Cloud's approach to big data and AI projects revolves around four stages of data management: data injection, data processing, data modeling, and application services.

The data injection stage involves collecting data from various sources, including internal Alibaba ecosystem data and third-party data. Alibaba Cloud's data integration capabilities ensure a seamless flow of data into the system, enabling efficient processing and analysis.

The data processing stage takes place in MaxCompute, Alibaba Cloud's Big Data Platform. Here, data scientists deploy models and run compute jobs to process and analyze the massive amount of data. MaxCompute's scalability and cost-effectiveness make it an ideal platform for handling the volume and complexity of big data.

Data modeling refers to the development and improvement of AI models. By continuously refining these models, Alibaba Cloud ensures that the results generated are accurate and up-to-date. This process is crucial for applications such as risk assessment, image search, and optimization algorithms.

Application services utilize the insights gained from data modeling to provide valuable services to external parties. Whether it is optimizing traffic flow, detecting incidents, or improving public transport routes, Alibaba Cloud's solutions leverage AI and big data to enhance various aspects of urban life.

4.2. Vertical Industry Solutions

Alibaba Cloud has developed specific solutions for different vertical industries, including finance, agriculture, and aviation. These solutions, known as "E-T Brains," address industry-specific challenges by utilizing big data and AI technologies.

One notable E-T Brain solution is City Brain, which focuses on addressing city management problems. City Brain utilizes data from multiple sources, including GPS data from taxis and buses, CCTV cameras, and traffic light control systems. By integrating and analyzing this data, City Brain provides holistic optimization in areas such as traffic Perception and optimization, incident detection and response, hazardous and special purpose vehicle tracking, and public transport optimization.

City Brain has been successfully implemented in multiple cities, both in China and beyond. Cities such as Macau have witnessed significant improvements in congestion rates, travel time, and public transport efficiency.

Conclusion

The effective utilization of big data and AI technologies is revolutionizing the e-commerce industry. Alibaba's success in leveraging these technologies is evident in its micro loan case and image search system. By using data-driven approaches and powerful platforms like MaxCompute, Alibaba Cloud has been able to address complex challenges and deliver innovative solutions.

Furthermore, Alibaba Cloud's design principles, focusing on the four stages of data management and developing industry-specific solutions, ensure the scalability, efficiency, and accuracy of its big data and AI projects.

As Alibaba Cloud continues to innovate and expand its offerings, more industries will benefit from the power of big data and AI. From finance to agriculture, Alibaba Cloud's solutions are reshaping various sectors, fueling the growth of a data-driven economy.
