New software package by our lab that can boost record linkage performance using language models - in one line of code, for free - all possible within a colab notebook! Do share any feedback!
#Econtwitter
Introducing LinkTransformer: LT brings the advantages of AI to standard data frame manipulation tasks like merges, deduplication, and clustering, making it easy to use large language models in a standard data wrangling workflow.

Our multimodal approach to record linkage goes beyond the use of corruption-prone OCR text for matching records and utilises information in the source image coupled with the 'language' in the text. We beat edit distance by over 20-30%! We'll actively develop the public codebase
Also multimodal methods for record linkage (), which avoid the OCR information bottleneck and leverage the power of a large language model. (7/8)
