  • Masked Graph Modeling for Molecule Generation ✉ Omar Mahmood 1, Elman Mansimov2, Richard Bonneau 3 & Kyunghyun Cho 2
    ARTICLE https://doi.org/10.1038/s41467-021-23415-2 OPEN Masked graph modeling for molecule generation ✉ Omar Mahmood 1, Elman Mansimov2, Richard Bonneau 3 & Kyunghyun Cho 2 De novo, in-silico design of molecules is a challenging problem with applications in drug discovery and material design. We introduce a masked graph model, which learns a dis- tribution over graphs by capturing conditional distributions over unobserved nodes (atoms) and edges (bonds) given observed ones. We train and then sample from our model by iteratively masking and replacing different parts of initialized graphs. We evaluate our 1234567890():,; approach on the QM9 and ChEMBL datasets using the GuacaMol distribution-learning benchmark. We find that validity, KL-divergence and Fréchet ChemNet Distance scores are anti-correlated with novelty, and that we can trade off between these metrics more effec- tively than existing models. On distributional metrics, our model outperforms previously proposed graph-based approaches and is competitive with SMILES-based approaches. Finally, we show our model generates molecules with desired values of specified properties while maintaining physiochemical similarity to the training distribution. 1 Center for Data Science, New York University, New York, NY, USA. 2 Department of Computer Science, Courant Institute of Mathematical Sciences, New ✉ York, NY, USA. 3 Center for Genomics and Systems Biology, New York University, New York, NY, USA. email: [email protected] NATURE COMMUNICATIONS | (2021) 12:3156 | https://doi.org/10.1038/s41467-021-23415-2 | www.nature.com/naturecommunications 1 ARTICLE NATURE COMMUNICATIONS | https://doi.org/10.1038/s41467-021-23415-2 he design of de novo molecules in-silico with desired prop- enable more informative comparisons between models that use Terties is an essential part of drug discovery and materials different molecular representations.

  • Operational Semantics with Hierarchical Abstract Syntax Graphs*
    Operational Semantics with Hierarchical Abstract Syntax Graphs* Dan R. Ghica Huawei Research, Edinburgh University of Birmingham, UK This is a motivating tutorial introduction to a semantic analysis of programming languages using a graphical language as the representation of terms, and graph rewriting as a representation of reduc- tion rules. We show how the graphical language automatically incorporates desirable features, such as a-equivalence and how it can describe pure computation, imperative store, and control features in a uniform framework. The graph semantics combines some of the best features of structural oper- ational semantics and abstract machines, while offering powerful new methods for reasoning about contextual equivalence. All technical details are available in an extended technical report by Muroya and the author [11] and in Muroya’s doctoral dissertation [21]. 1 Hierarchical abstract syntax graphs Before proceeding with the business of analysing and transforming the source code of a program, a com- piler first parses the input text into a sequence of atoms, the lexemes, and then assembles them into a tree, the Abstract Syntax Tree (AST), which corresponds to its grammatical structure. The reason for preferring the AST to raw text or a sequence of lexemes is quite obvious. The structure of the AST incor- porates most of the information needed for the following stage of compilation, in particular identifying operations as nodes in the tree and operands as their branches. This makes the AST algorithmically well suited for its purpose. Conversely, the AST excludes irrelevant lexemes, such as separators (white-space, commas, semicolons) and aggregators (brackets, braces), by making them implicit in the tree-like struc- ture.

Knowledge graphs (KGs) have become the preferred tech- nology for representing, sharing and adding knowledge to modern AI applications. While KGs have become a mainstream technology, the RDF/SPARQL-centric toolset for operating with them at scale is hetero- geneous, difficult to integrate and only covers a subset of the operations that are commonly needed in data science applications. In this paper we present KGTK, a data science-centric toolkit designed to represent, cre- ate, transform, enhance and analyze KGs. KGTK represents graphs in tables and leverages popular libraries developed for data science applica- tions, enabling a wide audience of developers to easily construct knowl- edge graph pipelines for their applications. We illustrate the framework with real-world scenarios where we have used KGTK to integrate and manipulate large KGs, such as Wikidata, DBpedia and ConceptNet.
