Figure 9
The figure shows six circles, each containing nodes marked with inverted triangles. All the nodes inside the circles are densely connected to each other with lines, forming an intricate web of interconnections that illustrate the relationship between different research areas. The largest circle among them is at the bottom left and includes numerous nodes related to computing, data processing, and quantum technology. The nodes in this circle are labeled as follows: “test method,” “big data,” “computer technology,” “cloud services,” “data processing,” “blockchain,” “field of cloud,” “management method,” “target data,” “storage medium,” “electronic device and medium,” “computer field,” “electronic device,” “storage media,” “processing method,” “computer program product,” “computer device,” “readable storage medium,” and “quantum technology.” The other five circles are of different sizes and are positioned toward the top of the image. Each of these circles contains eight nodes, which are interconnected, demonstrating how various methods, devices, and data types are related in Baidu’s patent landscape. Some of the nodes in these circles are labeled as follows: “search method,” “search term,” “search engine,” “display method,” “search results,” “text information,” “user input,” “web,” “information input,” “user experience,” “mobile terminal,” “interaction method,” “voice recognition,” “user information,” “terminal device,” “input method,” “control method,” “identification information,” “location information,” “speech recognition,” “recognition result,” “cloud server,” “target information,” “position information,” “electronic map,” “self-driving vehicle,” “point cloud data,” “vehicle driving,” “unmanned vehicle,” “map data,” “data collection,” “point cloud,” “detection method,” “lane line,” “neural network,” “points of interest,” “knowledge graph,” “prediction model,” “generation model,” “generation method,” “natural language,” “artificial intelligence,” “recognition model,” “recognition method,” “training data,” “classification model,” “model training,” “training samples,” “training method,” “feature vector,” “image recognition,” “feature extraction,”and so on.Network map of the most frequent topics in Baidu’s patents.
