What is BLAST: a loosely schema-aware meta-blocking approach for entity resolution about?

Identifying records that refer to the same entity is a fundamental step for data integration. Since it is prohibitively expensive to compare every pair of records, blocking techniques are typically employed to reduce the complexity of this task. These techniques partition records into blocks and limit the comparison to records co-occurring in a block. Generally, to deal with highly heterogeneous and noisy data (e.g. semi-structured data of the Web), these techniques rely on redundancy to reduce the chance of missing matches. Meta-blocking is the task of restructuring blocks generated by redundancy-based blocking techniques, removing superfluous comparisons. Existing meta-blocking approaches rely exclusively on schema-agnostic features. In this paper, we demonstrate how "loose" schema information (i.e., statistics collected directly from the data) can be exploited to enhance the quality of the blocks in a holistic __loosely schema-aware__ (meta-)blocking approach that can be used to speed up your favorite Entity Resolution algorithm. We call it B last (Blocking with Loosely-Aware Schema Techniques). We show how B last can automatically extract this loose information by adopting a LS
