A framework for creating web-based knowledge maps
Version 7 represents major progress in terms of future-proofing Head Start. It contains the result of a refactoring of the Head Start frontend in React and the introduction of a state-store based on Redux. The backend (data clients and machine learning pipeline) has been refactored into a microservice-architecture based on Docker containers, a Redis-queue and a Postgres database. In this release, knowledge map quality has been significantly improved by adding a default minimum-length for abstracts in BASE, improving the query sanitization and search behavior of data clients, as well as a range of metadata schema alignments, improved backward compatibility of the frontend, and various smaller bug fixes. The release also contains a new data client for Google Spreadsheets, which is the basis for CoVis. For more information on CoVis, please visit our projects page. Head Start has also been adapted to integrate with the new search-flow module resulting in a better search experience.

Version 5 also improves development, deployment, and maintenance of Headstart:
The Visual Project Explorer (VIPER) is a unique open science application created by Open Knowledge Maps that provides visual overviews of research projects indexed by OpenAIRE. It enables funders, institutions and researchers to systematically explore a project’s output, and to understand its impact in different areas. VIPER exploits a unique property of OpenAIRE data: the link between projects and publications and datasets.
To realize VIPER, we have adapted and extended Head Start. New features include:
VIPER also comes with a dedicated search interface for selecting projects for visualization as an example.
Version 4 is a milestone release focusing on usability, stability, design, and usefulness of Headstart.
Major improvements include:
As part of our mission of becoming ever more open, Headstart is now licensed under MIT 🎉
Version 3.5 introduces various new features and improvements both on the frontend and the backend, including
This release also includes a rewrite of the frontend with the following benefits:
Version 3 is our biggest release yet and represents a milestone for the project. It comprises of 347 individual commits.
Headstart 3 includes a wide variety of new and improved features:
Headstart 3 also represents a major step in terms of front-end design, development and deployment, including:
Version 2.9 is an interim release on the way to Headstart 3. It represents a first look at many of the improvements that we have scheduled for version 3. A major architectural upgrade is that the visualization components have been decoupled with the help of the mediator pattern. We have also implemented many improvements to the visualization interface, such as search highlighting and support for multiple languages. The PLOS search has been extentded to include a number of options, and more descriptive labels for research areas using a TF-IDF labelling algorithm.
This version will be used in the initial release of Open Knowledge Maps.
Version 2.7 integrates a persistence and versioning system based on SQLite. Pre-processing can now be handled by passing JSON strings instead of using CSV files. See search_plos.php for a prototypical implementation of this behaviour - it queries the PLOS API for the 100 most relevant results for a search term and creates a visualization on the fly.

Head Start is now part of the Open Knowledge Labs!
Version 2.6 mainly facilitates the integration of Head Start into other systems. A number of options have been introduced that make it easier to customize the visualization's behavior and appearance. By default, the screen real estate is now better utilized. In addition, several display issues have been fixed that occurred when the visualization was embedded in a existing website design. Finally, the system for academic evaluations introduced in v2.5 has been improved.
An adaptation of Head Start has been integrated in the conference scheduling system Conference Navigator 3 [registration required]. This version enables users to schedule papers directly from the visualization. Scheduled papers and recommended papers are highlighted.
