For more than 50 years, the Leibniz Institute for Psychology (ZPID) has offered a wide range of resources for researchers and practitioners in the field of psychology. These include, for example, the PSYNDEX database with literature and test references PsychArchives with research materials such as full-text documents, datasets, preregistrations, and other resources; the Research Data Center, and the Open Test Archive with freely accessible testing instruments. In all of these services, digital resources are documented to a high standard, archived for the long term, and made discoverable.
"As a central, supraregional infrastructure for psychology in the German-speaking world, ZPID has now integrated access to many of its services in one place. The new PsychPorta search portal allows users to access curated information from psychological research at a single, centralized location. “Several ZPID data sources are consolidated for the search, so that the various pieces of information can be found and interlinked within a single system. What makes this unique is that it is based on a linked-open-data knowledge graph,” reports Product Coordinator Ina Dehnhard, research associate in the Information and Retrieval department. “By building a knowledge graph, the information is not only collected but also clearly structured and presented in a meaningful way. Knowledge graphs are considered a key component of modern search systems and AI applications because they make connections and context easier to grasp. For example, search engines such as Google also use knowledge graphs to improve their search results.”
Katja Trillitzsch, Head of Information and Retrieval Services at ZPID, adds: “PsychPorta makes a significant contribution to supporting open science, as it ensures the transparency, reusability, and interoperability of scientific information. In addition, PsychPorta makes open-science features more visible by providing references to existing preregistrations, research data, funding agencies, and more.”
