    SELFIES and the future of molecular string representations

    Get PDF
    Artificial intelligence (AI) and machine learning (ML) are expanding in popularity for broad applications to challenging tasks in chemistry and materials science. Examples include the prediction of properties, the discovery of new reaction pathways, or the design of new molecules. The machine needs to read and write fluently in a chemical language for each of these tasks. Strings are a common tool to represent molecular graphs, and the most popular molecular string representation, SMILES, has powered cheminformatics since the late 1980s. However, in the context of AI and ML in chemistry, SMILES has several shortcomings -- most pertinently, most combinations of symbols lead to invalid results with no valid chemical interpretation. To overcome this issue, a new language for molecules was introduced in 2020 that guarantees 100\% robustness: SELFIES (SELF-referencIng Embedded Strings). SELFIES has since simplified and enabled numerous new applications in chemistry. In this manuscript, we look to the future and discuss molecular string representations, along with their respective opportunities and challenges. We propose 16 concrete Future Projects for robust molecular representations. These involve the extension toward new chemical domains, exciting questions at the interface of AI and robust languages and interpretability for both humans and machines. We hope that these proposals will inspire several follow-up works exploiting the full potential of molecular string representations for the future of AI in chemistry and materials science

    Tax administration reform in transition: the case of Croatia

    Get PDF
    This Occasional Paper reports the research results of a project on the tax administration in Croatia conducted by the Institute of Public Finance in Zagreb for the Croatian Tax Administration. The project team report was finalised in summer 1997 and it includes ten papers which are published in Croatian in the Institute’s journal “Financijska praksa”, Volume 22 , Number 1-2 (April 1998). This paper is the summary of the project written by Katarina Ott (Institute of Public Finance)
