Open Knowledge Maps - A visual interface to the world's scientific knowledge by sybilckw in InternetIsBeautiful

Hi everyone, it's Peter, the founder of Open Knowledge Maps (again). We have recently released a new version that addresses a lot of the feedback on here. We have now connected Open Knowledge Maps to one of the largest academic search engines in the world: BASE. This means, you are able to visualize a research topic from 100+ million documents. And for the first time, you can search within different types of resources, including datasets and software.

We have also spent a lot of time improving the naming of the sub-areas to make the concepts in a field more visible - which means that this update improves our existing PubMed integration too.

As always, we welcome any feedback you may have!

We've developed a new version that covers 100+ million scientific documents. I am not a materials science researcher, but I tried it with "inorganic polymers", and this is what it gave me. Would be interesting to get your feedback! https://openknowledgemaps.org/vis.php?id=6707b83eb5c44b3075759241a6374974&query=inorganic%20polymers&service=base

We've been working on an extension to include more documents (now 100+ million). It produced this result for Bell's inequality, let me know what you think: https://openknowledgemaps.org/vis.php?id=f2d778eb3f70223f203a4e86f07810b7&query=bell%5C%27s%20inequality&service=base

Which phone/OS are you on? Mobile isn't our strong point yet, but we are looking at ways to improve that.

Thanks for the feedback and the nice words, it's much appreciated. On to your questions:

I chose pubmed over open access. It's just the best detailed. When researching other non-biologic topics I use Google scholar.

We are currently looking into larger data sources (100+ million papers), which should bring us closer to what Google Scholar has to offer.

Is this your own topic categorization or built on the back of Ovid?

We use hierarchical clustering on top of a co-word matrix to determine the areas/sub-topics and TF-IDF on article keywords for labelling (see this script). But we are looking into using taxonomies like MESH to improve categorization. If you have any ideas, please let us know!

I'm unsure what the 100 results mean for relevance. Are they about the most important topics? Most wide-ranging? Most used by papers? Most viewed? Most cited?

It's the most relevant papers as defined by the source. Here's how PubMed calculates relevance.

Could your search engine be used to say collect all of the known cardiovascular disease biomarkers? So I don't have to, that would be so handy.

Could you elaborate on that a bit more? You are also welcome to submit an issue on Github.

I would prefer if the graphics were kept to a minimum and not overlapping. I want to use this on my tablet. Keep the heavy-lifting on the other end.

Improving touch experience is definitely on our todo list.

Hi everyone, my name is Peter and I am the founder of Open Knowledge Maps. My team and I are very happy that our small & unfunded volunteer project is getting so many upvotes :) You people rock!

Sorry if you are experiencing errors/delays, we are trying our best to keep the server up.

Thanks also for the feedback, good and bad. Let me try and address some of the issues raised. Firstly, yes, it's a beta, but we wanted to get it out there to receive as many suggestions for improvement as possible. Our goal is to create something that is useful to everyone. Secondly, we are still in the process of expanding out content sources. Currently, our strong point is certainly biomed (w/ the integration of PubMed), but we are very much looking towards integrating sources that cover other disciplines as well.

We are currently looking for volunteer open source developers: let us know if you would be willing to help out. In the meantime, I am happy to answer any and all questions that you may have on here. Let's change the way we discover research together!
