Journal of Cheminformatics is an open-access journal publishing original peer-reviewed research in all aspects of cheminformatics and molecular modelling.
Featured article - Learning chemistry: exploring the suitability of machine learning for the task of structure-based chemical ontology classification
Chemical data is increasingly openly available in databases such as PubChem, which contains approximately 110 million compound entries as of February 2021. With the availability of data at such scale, the burden has shifted to organisation, analysis and interpretation. Chemical ontologies provide structured classifications of chemical entities that can be used for navigation and filtering of the large chemical space. ChEBI is a prominent example of a chemical ontology, widely used in life science contexts. However, ChEBI is manually maintained and as such cannot easily scale to the full scope of public chemical data. There is a need for tools that are able to automatically classify chemical data into chemical ontologies, which can be framed as a hierarchical multi-class classification problem. In this paper, the authors evaluate machine learning approaches for this task, comparing different learning frameworks including logistic regression, decision trees and long short-term memory artificial neural networks, and different encoding approaches for the chemical structures, including cheminformatics fingerprints and character-based encoding from chemical line notation representations.
Featured Collection - In Silico Structure Generation: Recent Developments, Applications, and Challenges
This special collection showcases recent advances, applications, challenges in the enumeration of chemical structures: from the design to the analysis and use of either small, focused data sets, to large compound libraries. Analysis and handling of the newly constructed chemical structures include the storage, mining, integration of the constructed structures with other existing data sets, and curation.

The increasing volume of biomedical data in chemistry and life sciences requires the development of new methodologies and approaches for their analysis. Artificial intelligence (AI) and machine learning, especially neural networks, are increasingly used in the chemical industry, in particular with respect to big data. The collection presents progress and exemplifies the current needs, trends and requirements for machine learning in chemical data analysis.
The Journal of Cheminformatics is piloting use of the Citation Typing Ontology (CiTO) in its papers. Any author wishing to submit to the journal is free to participate in the pilot. To learn more about how, please click through to our dedicated page on the CiTO pilot and to see published papers already participating in the pilot.
COVID-19 and peer review
As a result of the significant disruption that is being caused by the COVID-19 pandemic we are very aware that many researchers will have difficulty in meeting the timelines associated with our peer review process during normal times. Please do let us know if you need additional time. Our systems will continue to remind you of the original timelines but we intend to be highly flexible at this time.
Benefit from our free funding service
We offer a free open access support service to make it easier for you to discover and apply for article-processing charge (APC) funding.
