One of the keys to the success of the Thousands of Problems for Theorem Provers (TPTP) problem library and related infrastructure is the consistent use of the TPTP language. This paper introduces the core of the TPTP language for higher-order logic – THF0, based on Church's simple type theory. THF0 is a syntactically conservative extension of the untyped(More)
There is a well established infrastructure that supports research , development, and deployment of first-order Automated Theorem Proving (ATP) systems, stemming from the Thousands of Problems for Theorem Provers (TPTP) problem library. One of the keys to the success of the TPTP and related infrastructure is the consistent use of the TPTP language. This(More)
Notations are central for understanding mathematical discourse. Readers would like to read notations that transport the meaning well and prefer notations that are familiar to them. Therefore, authors optimize the choice of notations with respect to these two criteria, while at the same time trying to remain consistent over the document and their own prior(More)
Interactive documents is an increasingly popular idea in todays world. The envision of an (inter)active document is that a reader should also be given the chance to adapt the document to his/her own preferences and needs apart from just reading it. This adaptation is not only in terms of customizing the display in the browser but also changing the content,(More)
Module systems for proof assistants provide administrative support for large developments when mechanizing the meta-theory of programming languages and logics. We describe a module system for the logical framework LF that is based on two main primitives: signatures and signature morphisms. Signatures are defined as collections of constant declarations, and(More)
We mark up a corpus of L A T E X lecture notes semantically and expose them as Linked Data in XHTML+MathML+RDFa. Our application makes the resulting documents interactively browsable for students. Our ontology helps to answer queries from students and lecturers, and paves the path towards an integration of our corpus with external sites. Over the last seven(More)
LATIN aims at developing methods, techniques, and tools for interfacing logics and related formal systems. These systems are at the core of mathematics and computer science and are implemented in systems like (semi-)automated theorem provers, model checkers, computer algebra systems, constraint solvers, or concept classifiers. Unfortunately, these systems(More)
Symbolic and logic computation systems ranging from computer algebra systems to theorem provers are finding their way into science, technology, mathematics and engineering. But such systems rely on explicitly or implicitly represented mathematical knowledge that needs to be managed to use such systems effectively. While mathematical knowledge management(More)
LF is a meta-logical framework that has become a standard tool for representing logics and studying their properties. Its focus is proof theoretic, employing the Curry-Howard isomorphism: propositions are represented as types, and proofs as terms. Hets is an integration tool for logics, logic translations and provers, with a model theoretic focus, based on(More)
