Looking for answers? Here are the frequently asked questions we received from curious users just like you.

There may be multiple reasons for this. We found the following to be most likely:
  • Your publication is too recent. Although we constantly update our database, we have to rely on the publisher of your article to inform the world about your contribution.
  • Your publication has no DOI assigned to it. If it has, please email the DOI to us.
  • Your publication is listed in a repository we are not aware yet. Send us a notice where we can find this repository.
There may be multiple reasons for this. We found the following to be most likely:
  • The given summary is written like a review. Please try to be more specific describing the background, the methods, the central research question, the context and the underlying research topic.
  • The provided abstract sounds like a political speech. Fair enough politicians talk the way they talk ... often without saying much. Our suggestion is to use more specific language in you input.
  • Your input seems to vague. Do you recognise what the following text is about: "This paper is about new findings of recent research we conduncted in our laboratory. Altough latest methods have been used it was quite difficult to get to the results." You can do much better than that. Be more precise.
These are placeholder strings and values for information that is not initially provided by the publishers. You will most likely find the missing details on the original source.
We believe that context matters. Especially in science and scientific publications. In order to account for that we created a model to represent context of words, word groups, sentences, and paragraphs. Processing keywords without context would just generate nonsense results. Therefore we require you to provide at least 200 characters to add meaning to you input. Just imagine the word AIR. Depending on the context the word air is used in it may mean 1) a mixture of gasses, 2) the region above the ground, or 3) the medium for radio broadcast ... and probably even more. To avoid ambiguity and the typical time consuming iterative search with keywords, we search with context and provide you the relvant results on the first attempt.
"Poor English" is the language of science. Sorry for the joke. However, the overwhelming majority of publications is in English or contains English translations of title and/or abstract. Thats why we decided to use English as our processing language. When you take a look at our changelog, we are planning to add a feature for auto-translation on non-english input. So we might get more flexible with other languages in the future.
Good point. We have this on the list as you can see in our changelog. Until this feature is available, we recommend the following short-cut: list all publications and do CTRL+F to use the search functionality of your browser.
This happens every now and then. This has to do with the way publishers submit information. For some reason the publiaction appears under two different digital object identifiers (DOI) in the repositories. In other cases, a publication and its supplements are registerred under the same title but different DOI. This is out of our hands. It is not a duplicate in our database. When you see such a situation take a look at the publishers website to find out why this happens.
