InfoGather: Entity Augmentation and Attribute Discovery By Holistic Matching with Web Tables
Summary: InfoGather augments entities and discovers attributes from web tables via holistic matching, enabling entity augmentation by name or example and attribute discovery with high precision. Topic-sensitive PageRank enables indirect table matching and multi-table aggregation; MapReduce preprocessing delivers near-interactive latency and four orders of magnitude speedup on 573M web tables.
