Customer Cases | Zilliz Cloud Powers AI Online Education: The Innovation Road of Smart Tree

[Live broadcast preview] Will large models replace programmers? "

Today, with the rapid development of information technology, the education industry is undergoing a profound change. Wisdom Tree, as the world's leading credit course operation service platform, has always been at the forefront of educational innovation.

In order to further improve the quality and efficiency of education, Wisdom Tree has joined hands with Zilliz Cloud to embark on a journey of deep integration of education and technology. Through Zilliz Cloud's efficient and intelligent vector database service, it not only optimizes the online learning experience, but also paints a blueprint full of possibilities for the future of education.

01. Wisdom Tree: The leader of online education

Wisdom Tree is not only an online education platform, it is also a bridge connecting teachers, students and educational institutions. By providing a variety of online video content such as live broadcasts, university shared classes, virtual experimental classes, and social practice classes, it provides a rich and diverse library of learning resources for users. At the same time, Wisdom Tree also provides a series of educational management, teaching and learning tools for school institutions, teachers and students, which greatly promotes the sharing and optimal allocation of educational resources. In the current era of profound changes in the education industry, Wisdom Tree has been committed to improving the quality and efficiency of education through technological innovation.

02.Zilliz Cloud: Helps smart trees easily cope with three core scenarios

As early as June 2021, Wisdom Tree chose Milvus when selecting a vector database. However, due to various reasons at that time, the deployed Milvus would go down about once a month on average, affecting online business. Subsequently, Zilliz launched Zilliz Cloud. After the Smart Tree was connected, it was found that its stability was greatly improved. Except for one time when an alarm was triggered due to insufficient CU pre-evaluation, it has always been running normally.

It can be said that the introduction of Zilliz Cloud has brought more convenience to the technological innovation of Smart Tree. As a fully managed cloud service, Zilliz Cloud not only provides high-performance vector search capabilities, but also greatly reduces operation and maintenance costs. Through Zilliz Cloud, Wisdom Tree can enjoy the support of a team of experts to quickly solve technical problems encountered in the business, ensuring the stable operation of the platform and the continued growth of the business.

Currently, the application scenarios of Zilliz Cloud in Wisdom Tree Company mainly include the following three:

Eliminate duplicate questions: improve question bank management efficiency by 50%

The question bank is one of the core resources of the online education platform. The question bank management of the Wisdom Tree platform faces a huge challenge: how to efficiently handle hundreds of millions of massive test questions and avoid data redundancy. Traditional text matching methods cannot meet this demand, and the text vectorization service based on Zilliz Cloud provides a brand new solution. Through AI algorithms, Wisdom Tree converts the question text into vectors, and then uses Zilliz Cloud to perform similarity retrieval, thereby achieving accurate test question deduplication. The application of this technology not only improves the efficiency of question bank management, but also saves teachers a lot of time and energy, allowing them to focus on the innovation and optimization of teaching content. For example, the original solution for the question bank deduplication business takes about 1 minute to deduplicate 100 questions uploaded by teachers, and after optimization, it takes about 30s.

Retrieval recommendation: enhance user experience, semantic recall response speed increased by 50%

Zilliz Cloud's semantic recall service provides powerful support for Wisdom Tree's retrieval recommendation system. By understanding the user's query intent, Zilliz Cloud can help Wisdom Tree more accurately match user needs and provide more relevant and high-quality search results. Its recall response speed is approximately 50% faster than the previous solution. This semantic-based search method greatly improves the user experience, allowing Wisdom Tree to maintain a competitive advantage in the fierce online education market.

Entity alignment: the key to building a knowledge graph, reducing time consumption by 72%

In the process of building a knowledge graph, entity alignment is a crucial step. Wisdom Tree uses Zilliz Cloud for persistence and similarity calculation of entity attribute vectors, which effectively solves the memory consumption problem in large-scale data processing and improves the efficiency of graph construction. Among them, the time consumption of the original solution in the process of aligning/disambiguating large-scale subject graphs with millions of nodes and tens of millions of edges has been reduced from about 3 days to 20 hours now, and the memory consumption of computing nodes has been reduced from the original 3 days to 20 hours. 100G, reduced to less than the current 32G. The application of this technology not only accelerates the construction process of the knowledge graph, but also provides the wisdom tree with richer and more accurate educational content associations, further enhancing the platform's educational service capabilities.

03.Customers say

Zhu Weibin, CTO of Wisdom Tree, said: "With the continuous advancement and application of AI technology, the cooperation between Wisdom Tree and Zilliz Cloud will not be limited to the above scenarios. We believe that AI technology will play a greater role in the education field in the future. To bring more innovation and change to online education, we will continue to use the power of technology to illuminate every learning dream.”
