Abstract

ULKB Logic is an open-source framework written in Python for reasoning over knowledge graphs. It provides an interactive theorem prover-like environment equipped with a higher-order language similar to the one used by HOL Light. The main goal of ULKB Logic is to ease the construction of applications that combine state-of-the-art computational logic tools with the knowledge available in knowledge graphs, such as Wikidata. To this end, the framework provides APIs for fetching statements from SPARQL endpoints and operating over the constructed theories using automated theorem provers and SMT solvers (such as the E prover and Z3). In this paper, we describe the design and implementation of ULKB Logic, present its interfaces for querying knowledge graphs and for calling external provers, and discuss a use case of commonsense reasoning in which ULKB Logic is used as the target logic for representing the semantics of English sentences.

期刊介绍: Science of Computer Programming is dedicated to the distribution of research results in the areas of software systems development, use and maintenance, including the software aspects of hardware design. The journal has a wide scope ranging from the many facets of methodological foundations to the details of technical issues andthe aspects of industrial practice. The subjects of interest to SCP cover the entire spectrum of methods for the entire life cycle of software systems, including • Requirements, specification, design, validation, verification, coding, testing, maintenance, metrics and renovation of software; • Design, implementation and evaluation of programming languages; • Programming environments, development tools, visualisation and animation; • Management of the development process; • Human factors in software, software for social interaction, software for social computing; • Cyber physical systems, and software for the interaction between the physical and the machine; • Software aspects of infrastructure services, system administration, and network management.
