LingoAI constructs an AI x DePIN network that targets accessing low-resource language corpora necessary for AI development. LingoAI pioneered the fusion of Web3.0 and AI's MetaGraph technology stack from the ground up. MetaGraph merges large language models (LLM) with knowledge graphs, RAG, equipping LLMs to eradicate "hallucinations." LingoAI employs underlying semantic web layer to achieve the separation of data and applications through SOLID and MetaLife.Social protocol, the return of user data autonomy aims to form a global decentralized data trading market to address the prevalent AI data scarcity caused by Web2.0 data silos.
