Article Introduction：Graph Retrieval Enhanced Generation (GraphRAG) is gradually becoming popular and has become a powerful complement to traditional vector search methods. This method takes advantage of the structural characteristics of graph databases to organize data in the form of nodes and relationships, thereby enhancing the depth and contextual relevance of retrieved information. Graphs have natural advantages in representing and storing diverse and interrelated information, and can easily capture complex relationships and properties between different data types. Vector databases are unable to handle this type of structured information, and they focus more on processing unstructured data represented by high-dimensional vectors. In RAG applications, combining structured graph data and unstructured text vector search allows us to enjoy the advantages of both at the same time, which is what this article will discuss. structure

Article Introduction：Horizontally scrollable sections are a common web design pattern used to display content that exceeds the width of the viewport. This design pattern allows users to scroll horizontally, providing a unique and engaging way to display large images, galleries, timelines, maps, and other content. This is achieved by using CSS properties such as overflow−x:auto or overflow−x:scroll. This uses native browser functionality for horizontal scrolling and is responsive across devices. Allows easy navigation and exploration of content. It does not require any additional libraries or plugins. The algorithm uses the "container" class to define container elements. Set the container's "overflow−x" property to "auto" to enable horizontal scrolling. container

Article Introduction：In natural language processing, vector modeling is to represent text into vector form to facilitate computer processing. This method treats text as points in a high-dimensional vector space and measures similarity by calculating the distance or angle between them. Vector modeling has become an important technology in the field of natural language processing and is widely used in tasks such as text classification, text clustering, information retrieval and machine translation. The basic idea of ​​vector modeling is to represent words in text as vectors, and represent the entire text as a weighted sum of these vectors. The purpose of this is to capture the semantic and grammatical relationships between words. The word embedding model is trained by using techniques such as neural networks and matrix decomposition to generate a low-dimensional vector representation of each word. These vectors typically have hundreds to thousands of dimensions
