So far we basically just provide a very rule-based approach and try not use LLMs as much as possible. So we extract and parse the citations using various ML and rule-based approaches, and carry out a bunch of predetermined queries and do various fuzzy matching approaches on the metadata components, and have a bunch of rules around risk levels of things we should have found/matched based on what type of source it is, which venue we should have found it in, etc.

So there are absolutely a bunch of tasks that could be evaled/benchmarked, but "hallucination rate" isn't particularly applicable/interesting as a metric of how good the tool is

that said, we do use various LLMs (mostly local, fine-tuned, small, for things like NER/parsing/metadata comparison, etc.). and they can and do hallucinate, but we have very hard constraints on the validation, so any extraction results that don't match 1:1 back to the input text are discarded for example. so again, rather than hallucination risk we prefer hard constraints

Nick Morley from Grounded AI here (https://groundedai.company)

We collaborated with Nature here to study the extent of fake/frankenstein citations in scholarly literature (from top 5 publishers - Springer, Elsevier, Wiley, Sage, Taylor & Francis)

We're estimating hundreds of thousands of papers affected in 2025 with hallucinated citation issues

As part of the work we analysed 20k papers generated with ChatGPT API to figure out which citation errors are characteristic of gen AI use and use that classify the errors we saw in the wild.

The world's gone mad, publishing is in a nuts state, the training data is poisoned!

yeah this makes sense. we run a citation verification service and provide publishers with data of hey this citation could be fake etc. but we don't currently capture any "action" or "measured result" so i guess that's what we need to expand to next

Trying to think about our best chance of making a lasting contribution (therefore actually surviving?) as a startup.

I'm a big fan of focusing on verification tools ("Verification is all you need"?) but who knows.

I'm sure I'm missing something in my perspective. Here to expand my aperture

That's basically what we're doing with app.studyrecon.ai.

What we've found is that vector similarity is often not the final solution. It is still only a crude proxy for the true goal of 'informativeness' or 'usefulness' with relation to the user goal/query. Works okay, but we're definitely seeing a need for more rigorous LLM-postprocessing to enrich the results set.

Which, yes, the time adds up quick!

Here's my attempt at a simple explanation of transformers. I would love feedback on whether I've got it right and how I could improve it. Cheers

I agree, it's currently very superficial. It would be great to recognise and show more about the specific nature of the relationships.

What kind of thing would you hope to see here? A textual summary of the relationship? Or perhaps there is more that can be done with shapes and colours in this area?

One of the creators here.

The keywords are grouped such that keywords that occur together often are in the same group. The colour represents this grouping.

There may be more useful groupings we could give or allow the user to choose between. We would be interested to hear any ideas for that

Really like the idea of trying to improve things that are so widely adopted and entrenched that most (me, at least) don't think to change.

We face the problem that people differ in what they think the features should be though. Ideally we would have a method to deduce what's the best symbolism for maximising input/output speed to human's minds. Some kind of scientific voodoo.

Beyond me what that might be.

There are philosophical differences and practical differences. They are trying to build an AI scientist ground-up (love it). I would like to optimise for front-line use cases in a lean, user-driven manner. The common denominator technologically is knowledge extraction (text to subject-predicate-object triples), ontological mapping (e.g, these relationships express the same thing, these references are synonyms of this compound, etc.), and reasoning (comes free once you have information properly extracted and mapped with a schema in place thanks to knowledge graph implementations such as GraKn).

Practically speaking: Aristo takes questions in unstructured text, and answers in unstructured text. I'm interested in providing mechanistic queries and comprehensive, highly-structured result sets.

For a question such as, "what are the biological consequences of increasing the activity of molecule A", I want tabular and filterable results (where the number of rows depends on the volume of underlying data and the degrees of separation you carry the inference to). For this reason (alongside their current limitation to elementary science) I argue that Aristo is not currently a relevant resource for researchers and students looking to query and survey biomedical relationships.

The solution I'm aiming at takes a structured query and returns structured results. E.g, a query: [entity: molecule A, direction: increase] generates a list of direct and inferred consequences. It is more like a logic-driven search engine over structured information than it is a question answering system.
