There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

The author systematically examines one of the important issues of information — establishing the market price. He introduces the concept of «search» — where a buyer wanting to get a better price, is forced to question sellers. The article deals with various aspects of finding the necessary information.

Generative artificial intelligence (AI) is a form of AI that can autonomously generate new content, such as text, images, audio, and video. Generative AI provides innovative approaches for content production in the metaverse, filling gaps in the development of the metaverse. Products such as ChatGPT have the potential to enhance the search experience, reshape information generation and presentation methods, and become new entry points for online traffic. This is expected to significantly impact traditional search engine products, accelerating industry innovation and upgrading. This paper presents an overview of the technologies and prospective applications of generative AI in the breakthrough of metaverse technology and offers insights for increasing the effectiveness of generative AI in creating creative content.

This is the preprint version of our paper on ICONIP2015. The proposed platform supports the integrated VRGIS functions including 3D spatial analysis functions, 3D visualization for spatial process and serves for 3D globe and digital city. The 3D analysis and visualization of the concerned city massive information are conducted in the platform. The amount of information that can be visualized with this platform is overwhelming, and the GIS based navigational scheme allows to have great flexibility to access the different available data sources.

In online learning systems, tagging knowledge points for questions is a fundamental task. Automatic tagging technology uses intelligent algorithms to automatically tag knowledge points for questions to reduce manpower and time costs. However, the current knowledge point tagging technology cannot satisfy the situation that mathematics questions often involve a variable number of knowledge points, lacks the consideration of the characteristics of the mathematics field, and ignores the internal connection between knowledge points. To address the above issues, we propose a Sequence Generation Model Integrating Domain Ontology for Mathematical question tagging (SOMPT). SOMPT performs data augmentation for text and then obtains intermediate text based on domain ontology replacement to facilitate deep learning model to understand mathematical question text. SOMPT is able to obtain dynamic word vector embedding to optimize the textual representation for math questions. What’s more, our model can capture the relationship between tags to generate knowledge points more accurately in the way of sequence generation. The comparative experimental results show that our proposed model has an excellent tagging ability for mathematical questions. Moreover, the sequence generation module in SOMPT can be applied on other multi-label classification tasks and be on par with the state-of-the-art performance models.

Sequence Generation Model Integrating Domain Ontology for Mathematical question tagging

When Facebook changed its name to Meta, the upsurge of the metaverse was violently set off. Every company starts claiming they're working on the Metaverse, and everybody talks about the Metaverse. There isn't any formal definition of the Metaverse. This article first introduces the relationship between human beings and the universe, then uses philosophical methods to explore the definitions of the universe and the metaverse, and then tells several philosophical stories related to the metaverse to map the definition of the metaverse.
