The power to uncover hidden connections

Research data is booming.  The opportunity to reveal meaningful linkages–between past and current research, between collaborators, between funding and research impact–is huge, as long as you start with the right data. With Web of Science, over 7,000 academic and research institutions, national governments, funding organizations, and publishing organizations around the world are finding new connections in research every day.


“Among many other things, we help people find research collaborators from other disciplines, locate evidence of emerging and ‘hot’ research topics, provide resources and guidance on potential funding sources, and support proposal preparation through bibliographic and data management planning services. Understanding where excellence is happening and then being able to help people make the right connections is really powerful.”

Beth Ten Have, Director of Library Academic Partnerships, Drexel University

What makes Web of Science different?

Quality and quantity

Web of Science is a comprehensive research platform. Journal articles, patents, websites, conference proceedings, Open Access material—all can be accessed through one interface, using a variety of powerful search and analysis tools. Web of Science Core Collection is a painstakingly selected, actively curated database of the journals that researchers themselves have judged to be the most important and useful in their fields. However, add-in our Emerging Sources Citation Index and the other indexes we provide, and you get over 25% more coverage from the nearest competitor.


When we index a journal, we mean the whole thing

That may seem obvious, but it’s not. Some citation databases don’t index all papers covered in a journal, meaning you can’t be sure that you’ve uncovered all of the research relevant to your work. We index every journal cover-to-cover: every paper published, and every author and institution listed. You can’t get much more complete than that.


You need to understand the past-it informs the future

With the full Web of Science archive, you can search across papers, books, conference proceedings, data sets and patents all the way back to 1900. But there’s more. The captured citations across all this work create a unique network of 1 billion connections between ideas, people and institutions. Use this to trace scientific work backwards in time to reveal early thinking, and not miss anything even when terminology is changing rapidly.


Unbiased journal impact

We are not a publisher. We are transparent with our methodology for measuring journal impact. That’s why our Journal Impact Factors and Journal Citation Reports are trusted as the industry standard.


“One of the reasons for choosing Clarivate Analytics is their long-standing expertise in bibliometric analysis. We needed a partner whose reputation would provide reassurance that the analysis of research outputs is independent, of the highest quality and that the numbers are reliable.”

Magda Gunn, Scientific Project Manager Responsible Strategic Area Diabetes & Metabolic Disorders, Innovative Medicines Initiative.


It's our job

Our editorial team works full-time on evaluations and collection management and has done so for many decades, day-in and day-out with no other professional commitments or conflicts of interest.


Authors are important…

Unlike our competitors, we capture full names for 100% of authors on every paper, and associate these with their address and affiliation in a database, which we maintain. So it doesn’t matter if you’re author number 1 or 200, you’re covered.

…and so are institutions

In order to measure impact, you need to be able to accurately associate citations to papers, to people, and to institutions. We capture 100% of the authors, affiliations and citations for every paper, and we apply human developed rules and proactive validation with institutions, meaning that you can accurately measure and compare research performance.


Ability to link output to impact

In research, citations are critical. But other types of data are important too. That’s why Web of Science offers funding acknowledgement data and content from the Derwent Patent Citation Index. This makes it easier to link funding with research output and impact.

“Clarivate Analytics provides us with the data we need to understand the impact of the research community in their own disciplines and on the broader world, and to identify our collaborative success stories across thousands of researchers affiliated with the university.”

Director of Research and Analysis, Office of the Provost
