How to find new Papers |

A couple of people who are just participating in their first seminar might ask themselves how you can find interesting new publications (papers). I would like to shed some light on it.
The hardest part is when you're new to a field. You don't know which journals are the important ones, which authors are most respected in the field, which terms are used.
Automated journal rankings like the h5-index used by Google Scholar (see metrics, Wikipedia) is one way to deal with the lack of domain knowledge. Google Scholar even publishes a list of journals per field (see Top publications in Computer Vision and Pattern Recognition).

I've never tried it (on purpose), but the idea just came to my head: Use a random walk. You start with some paper of which you don't really know if it is good. Look at the references and try to weild out the ones which are obviously not work trying (e.g. because they are websites). Now take a random one to continue with. Do this a couple of times.
The idea is that papers which are more important are much more often cited. So you can hope to get to more important papers over time.
Search for papers via Google. Look at the references. Search for papers in the reference. Get a feeling for the language being used.
When you have a little bit of domain knowledge (or a starting paper given to you by your supervisor) everything gets a lot easier.
There are a couple of key strategies:
- Looking at the references of a paper
- Looking at what else the same author published
- Looking for similar titles
- Reading Journals
For all three of them, I can highly recommend Google Scholar. They also offer a nice overview / statistics about authors so that you can get a feeling for their scientific activity. But don't let you fool you by those numbers: It is possible to fake them.
The other nice thing is that Google Scholar makes citing publications incredibly easy:

The arXiv can be seen as THE "modern way" journal. Depending on the field, it has a VERY high reputation.
For Pattern Recognition the reputation of the arXiv is amongst the highest ten journals, but it there are some fields like physics where it is THE top journal in several subfields like cosmology or high energy physics.
What makes the arXiv stand out is the fact that you can read new papers every day. I like to have a view at cs.CV/recent to keep myself informed about new stuff. There are about 20 new publications per day. On some days, there is nothing interesting, on other days like today quite a bit:
- The MegaFace Benchmark: 1 Million Faces for Recognition at Scale
- Rethinking the Inception Architecture for Computer Vision
- Labeling the Features Not the Samples: Efficient Video Classification with Minimal Supervision
- Attribute2Image: Conditional Image Generation from Visual Attributes

I filter publications like this:
- First, I look at the title. If that doesn't look interesting, I skip it. The more exact the title is, the better. If it is too vague, I sometimes skip it too because the authors seem not to be familiar with the scientific style of writing and thus are probably not able to write an interesting paper.
- Then I read the abstract. I expect to get to know what the paper is about.
- Then I look at images / tables (depending on the subject)
- I read the conclusion / last part
- I read the end of the introduction where it often says "the paper is structured as follows"
I guess many researchers filter like this. This is important to know when you write a paper.
