One of the challenges of today`s information §society §is to cope with the immense amount of digitally §stored texts. Progress in this area could be made §if §computers could somehow understand these texts or even §answer questions about their content.§This Master`s thesis describes a possible approach §to this challenge. It examines how computers could §answer common sense questions on a text by §combining §natural language processing, automated reasoning §and §ontological knowledge. A practical side describes a §prototypical system that applies a theorem prover §to §natural language and ontological knowledge. A §theoretical side is concerned with the §transformation of Higher Order Logic, which is used §in the ontology, to First Order Logic that can be §digested by theorem provers. Particular attention §is §paid to the efficient handling of equality and the §adequate representation of propositional predicates §in First Order Logic. These experiences and §analyses §could be first stepping stones towards opening the §world of natural language reasoning to computers.
