What is Siren?
Siren operates at the intersection of semantic search and large-scale data analytics. Originating as a spin-off from the Data Intensive Infrastructure research group at NUIG, the company leverages the SIREn (Semantic Information Retrieval ENgine) framework to process and interpret billions of edges within knowledge graphs. By utilizing markup standards such as schema.org, the platform enables enterprises to derive actionable intelligence from unstructured and semi-structured web data. Its market position is defined by its ability to bridge the gap between raw data crawling and high-level semantic understanding, providing a critical layer for organizations managing complex, interconnected datasets.
