This post is evolving from a reading list to a review of the academic papers published that are either about or use the Biological Expression Language (BEL). It’s divided into the categories of software/visualization tools, algorithms/analytical frameworks, data integration, natural language processing, curation workflows, and downstream applications.

In my history of BEL, I imposed some quality and impact standards. Without getting into a debate about how peer review is broken because it’s missing these standards, this list is more inclusive to papers whether they are likely to be reproducible or useful to the community, or not.

Some of the papers in this list were tricky to find - many of the PMI papers do not mention BEL in the abstract and the journals in which their papers were published don’t seem to index properly in MEDLINE. You’re welcome to use my search on PubMed and my search on Europe PubMed Central to see for yourself. I also looked through the publication lists of some of the key authors from Selventa and PMI over the last 10 years to find several other application papers. As always, this list is incomplete due to the lack of findability/accessibility of papers, my lack of knowledge of everything, and lack of time to deeply read through all authors’ histories. If you know of a search tool that might be helpful for improving this list, please let me know. I’ve been meaning to check out CoCites:

As always, improvements are welcome. Check my contact info at the bottom of this post. I’ll be making a major update to this post later to be more like a review as I’m putting together the new BEL reference paper.
