Entity Matching using Large Language Models

1 code implementation17 Oct 2023 Ralph Peeters, Christian Bizer

We show that for use cases that do not allow data to be shared with third parties, open-source LLMs can be a viable alternative to hosted LLMs given that a small amount of training data or matching knowledge...

Using ChatGPT for Entity Matching

1 code implementation5 May 2023 Ralph Peeters, Christian Bizer

Always using the same set of 10 handpicked demonstrations leads to an improvement of 4. 92% over the zero-shot performance.

Supervised Contrastive Learning for Product Matching

1 code implementation4 Feb 2022 Ralph Peeters, Christian Bizer

We thus conclude that contrastive pre-training has a high potential for product matching use cases in which explicit supervision is available.

Cross-Language Learning for Entity Matching

1 code implementation7 Oct 2021 Ralph Peeters, Christian Bizer

This poster explores along the use case of matching product offers from different e-shops to which extent it is possible to improve the performance of Transformer-based matchers by complementing a small set of training pairs in the target language, German in our case, with a larger set of English-language training pairs.

Cross-Lingual Transfer Entity Resolution

Dual-Objective Fine-Tuning of BERT for Entity Matching

1 code implementation Proceedings of the VLDB Endowment 2021 Ralph Peeters, Christian Bizer

The task can be approached by learning a binary classifier which distinguishes pairs of entity descriptions for the same real-world entity from descriptions of different entities.

Intermediate Training of BERT for Product Matching

2 code implementations DI2KG: International Workshop on Challenges and Experiences from Data Integration to Knowledge Graphs @ VLDB 2020 2020 Ralph Peeters, Christian Bizer, Goran Glavas

Adding the masked language modeling objective in the intermediate training step in order to further adapt the language model to the application domain leads to an additional increase of up to 3% F1.
