Introducing the Mendeley catalog search engine

Last Fall, we wrote about finding what is relevant to your research. We have a long way to go until we reach even half of our goals in helping you discover great content, but we are one tiny step closer as of today.

Today we launched a catalog search engine on the Mendeley Website. Moreover, we already have an advanced search that will be released in two weeks building on top of what you can use starting today. You can start using the basic search by going to the Research papers page.

What is different about Mendeley search compared to other literature search engines?
Two things standout: 1) Diversity of the literature and 2) ReaderRank

Diversity of the literature
Because Mendeley encompasses a broad range of academic disciplines, we have enormous diversity in our data set to draw results from. This is great, but also a challenge. The challenge comes from delivering results that are relevant to you and avoiding ambiguity with other disciplines. This WILL improve as we make tweaks and personalize the search experience. What’s great about this diversity though, is that inter-disciplinary content will surface if it is relevant.

ReaderRank
Relevant content is the strongest factor in the results you receive, but we wanted to take advantage of the knowledge of the crowds as well. With that in mind, we have developed an algorithm called ‘ReaderRank’ that will adjust results based on the level of readership for an article. This doesn’t mean the most read articles will always appear at the top, only that it is an additional measure in ranking your results. We have also taken care to prevent artificial enhancement of the results, i.e. gaming the readership. Over time, we hope to refine this algorithm by taking into account other measures of quality such as the reputation of who you trust and follow on Mendeley.

Once again, we will release an advanced search in two weeks that will let you refine search queries. We also want to encourage feedback. So, if you have any thoughts about the quality of results or what you might like to see in terms of search features, please let us know by going to our feedback forum.

Announcing the Mendeley Open API – Call for proposals

It’s almost here, the Mendeley Open API that third-party developers can use to create their own mashups. The API won’t be immediately available to everyone quite yet, but we would like to invite any developers interested in early access to submit a proposal of what you envision building.

The call for proposals is open until Friday, May 14th. Selected developers will be notified between now and May 21st.

For more information on how to submit your proposal please see the Open API page.

For more information about the API methods please see the API methods page.

If you take a look at our feedback page you will quickly see how many feature requests we are getting on a daily basis. We would love to implement all of them, but unfortunately that isn’t possible. Additionally, many researchers require niche-specific tools that are not suitable for inclusion in a general purpose tool such as Mendeley. The obvious solution to both of these problems is to open up the data and let creative developers and inspired academics create what they need on top of that data.

With the Open API, you will have access to both aggregated statistics and your own library. Developers can create applications to improve your research experience (for privacy reasons, you will need to authenticate yourself before third-party applications can access your data). Libraries and publishers can build simple Web apps to pull in article-level metrics to enhance what you see when visiting their websites.

We are extremely excited to see what the community and developers, who for years have not had access to this type of data, can create with the API tools. For far too long, this type of data has been siloed away from the general developer community; even worse, the end-user researchers. The richness of academic knowledge is finally in an accessible and open form, so that “Silicon Valley” and other creative developers around the world have a practical means to participate in scientific research. The world is now connected to academia.

Meet Tim Keitt – Integrative Biologist and Mendeley Power User

Tim Keitt is a researcher at the University of Texas at AustinDuring a recent trip to Texas for the Non-hematopoietic and mesenchymal stem cells meeting, I took a little side trip to the University of Texas at Austin to meet one of Mendeley’s power users. We talked about his research, new projects he is working on and how Mendeley helps him collaborate with his colleagues in South America.

How Dr. Keitt is using Mendeley in his research

Dr. Keitt finds a great deal of value in the collaborative aspects of Mendeley, allowing him to share papers with colleagues distributed around the globe, no matter what OS they use, but he also sees a lot of value in the development of a new citation infrastructure. One application he mentioned here was correction for “citation mutation”, the process wherein a citation gets repeated in successive papers slowly accumulating transcriptional errors until it no longer can be traced back to the original work.

Insights from Integrative Biology

It was really fascinating for me to hear him talk about ecosystem patterns because one of my earliest scientific fascinations was with fractals, a type of pattern found throughout nature. While much of his earlier research involved fieldwork, he’s started doing more molecular work with the advent of better molecular tools for studying and identifying species similarity.

In this respect, large scale biological datasets have become very important to him. One project, which may lead to the creation of a HapMap-style database for non-human species, has made him particularly aware of how idiosyncratic the metadata associated with database entries can be. While having access to larger-scale data has made some scientific questions more tractable, it has also raised its own set of challenges. He gave an example here which I think is instructive for many of the issues scientists are now facing as we put more and more data online and seek effective tools for facilitating collaborations.

In the early days of sequencing, each research group would have their own database with its own structure and that worked just fine, until confusion arose regarding how to refer to a specific sequence and people started to try to merge databases to prevent duplication. We now have the GenBank as a centralized repository for sequence information and sequences can be unambiguously identified by referring to their accession number, but we didn’t get there until editors started requiring that manuscripts reporting sequences contain the Genbank accession number.

Editors forced the issue in this case, but any effort to systematize the reporting of sequences initially would have faced challenges such as who controls the repository and why should a busy researcher bother submitting to it. Repeat that last sentence again, and if you’ve followed any of the discussion about online engagement of scientists with literature, it should sound very familiar.

From Molecules to Ecosystems

Dr. Keitt got his start working in the rainforests of the Amazon where he studied species variance in one of the most diverse ecosystems on planet. Later, he came to the University of Texas where he continues to work on the effect of ecosystem patterning on species diversity. While he no longer does a great deal of fieldwork, he still collaborates with colleagues in South America for ongoing projects. He’s done some work on the Bachman Sparrow in Texas and is really excited about a upcoming project studying coral in Micronesia.
