๐ ๏ธ Technical Deep Dive
- Data Sources: SciAtlas primarily extracts different entity types and preserves key attributes from OpenAlex.
- Schema: It features a sophisticated schema encompassing 9 categories of entity nodes, including papers, authors, institutions, keywords, and research fields. Each node type is endowed with comprehensive attribute information, such as paper abstracts, PDF URLs, and author citations.
- Relational Edges: The graph includes 12 categories of relational edges, such as citations, authorship, co-authorship, and keyword co-occurrence.
- Neuro-symbolic Retrieval Algorithm: The core retrieval mechanism employs a neuro-symbolic approach featuring 'tri-path collaborative recall and graph reranking.' This algorithm is designed to transition from simple semantic matching to deterministic association discovery, leveraging both neural networks and symbolic reasoning for enhanced interpretability and generalization.
- Public Availability: Interfaces for knowledge graph retrieval and various downstream tasks are provided via a GitHub repository.
