StruBERT: Structure-aware BERT for Table Search and Matching

1 code implementation27 Mar 2022 Mohamed Trabelsi, Zhiyu Chen, Shuo Zhang, Brian D. Davison, Jeff Heflin

In this paper, we propose StruBERT, a structure-aware BERT model that fuses the textual and structural information of a data table to produce context-aware representations for both textual and tabular content of a data table.

Leveraging Schema Labels to Enhance Dataset Search

no code implementations27 Jan 2020 Zhiyu Chen, Haiyan Jia, Jeff Heflin, Brian D. Davison

We incorporate the generated schema labels into a mixed ranking model which not only considers the relevance between the query and dataset metadata but also the similarity between the query and generated schema labels.
