Head Start is a web-based knowledge mapping software intended to give researchers a head start on their literature review (hence the name). It comes with a powerful backend that is is capable of automatically producing knowledge maps from a variety of data, including text, metadata and references.
To get started, clone this repository. Next, duplicate the file
config.example.js in the root folder and rename it to
Make sure to have
npm version 3.10.10 installed (it comes with Node.js 6.12.0, you can download installers here) and run the following two commands to build the Headstart client:
npm install npm run dev
We are using webpack to build our client-side application.
webpack is started in watch mode which means that changes to files are tracked and the created
headstart.js is automatically updated.
Now you can run a local dev server:
To run Headstart on a different server (e.g. Apache), you need to set the publicPath in
config.js to the URL of the
- Dev: specify the full path including protocol, e.g.
- Production: specify the full path excluding protocol, e.g.

If everything has worked out, you should see the visualization shown above.
See client configuration for details on adapting the client.
Also see visualization options.
- Interactive, web-based knowledge maps based on D3.js, following Shneiderman's principle of "overview first, zoom and filter, then details-on-demand"
- Synchronized list representation of documents complementing the knowledge map
- Integrated PDF viewer and annotation tool, courtesy of Hypothes.is
- Powerful server component written in PHP and R for the creation of knowledge maps, including algorithms for clustering, ordination and labelling
- Connectors to a number of academic search engines through rOpenSci, including BASE, PubMed, PLOS and DOAJ
- Persistence and versioning system based on SQLite
- Open Knowledge Maps: Creates a visualization on the fly based on a user's search in either BASE or PubMed.
- VIPER - The Visual Project Explorer: Provides overviews of research projects indexed by OpenAIRE.
- CRIS Vis: Enables the exploration of crowd-sourced research questions related to mental health.
- Overview of Educational Technology: A working prototype for the field of educational technology based on co-readership.
- OpenUP Dissemination Toolbox: A prototype showcasing an overview of innovative dissemination case studies.
- Conference Navigator 3 [registration required]: An adaptation of Head Start for the conference scheduling system CN3. This version enables users to schedule papers directly from the visualization. Scheduled papers and recommended papers are highlighted.
The visualization has been successfully tested with Chrome, Firefox, Safari and Microsoft Edge. Unfortunately, Internet Explorer is not supported due to the fact that it is not possible to insert HTML into a foreignObject.
