Simplified Data Wrangling with ir_datasets [article]

Sean MacAvaney, Andrew Yates, Sergey Feldman, Doug Downey, Arman Cohan, Nazli Goharian
2021 arXiv   pre-print
Integrations with popular IR indexing and experimentation toolkits demonstrate the tool's utility.  ...  Dataset documentation is scattered across the Internet and once one obtains a copy of the data, there are numerous different data formats to work with.  ...  Since experiments in neural IR frequently only work with a small subset of documents, this is very beneficial for these pipelines.  ...

Pretrained Transformers for Text Ranking: BERT and Beyond [article]

Jimmy Lin, Rodrigo Nogueira, Andrew Yates
2021 arXiv   pre-print
This survey provides an overview of text ranking with neural network architectures known as transformers, of which BERT is the best-known example.  ...  The combination of transformers and self-supervised pretraining has been responsible for a paradigm shift in natural language processing (NLP), information retrieval (IR), and beyond.  ...  To better understand the reproduction difficulties with the CEDR codebase, we replicated some of the important model configurations using the Capreolus toolkit ] to obtain new results with the different  ...

Development of Software Platforms for Annotation and Dereplication of Peptidic Natural Products

2020
The annotated peaks are not always the same as the scored peaks because some peaks with unusual neutral losses or adducts are not used for the scoring.  ...  Secondly, working with relational databases requires defining schemes that strictly fit with the data, reducing the flexibility and not allowing the introduction of unstructured data, as needed in our  ...  For the deployment of my tools I used Apache Tomcat, which benefits from a light footprint and high flexibility.  ...
