SemIndex+: A semantic indexing scheme for structured, unstructured, and partly structured data

作者:

Highlights:

• Search, select and rank unstructured, structured (relational) and partly structured (NoSQL) data.

• Maps a textual data collection and a semantic knowledge base into a tightly-coupled semantic graph.

• Involves users during semantic index creation, initial query formulation and query refinement.

• Parallelized query processing, with a dedicated model for answer weighting and relevance scoring.

• Comparative experiments with legacy methods highlight solution’s flexibility & effectiveness.
