Knowledge Representation for Natural Language Processing

The logic-based knowledge representation language L_LILOG, which is used to represent both the semantic background knowledge as well as the information extracted from German texts within the LILOG project, is discussed. L_LILOG integrates frame-like ...

This special issue presents the state-of-the-art in implemented, general-purpose Natural Language Processing (NLP) systems that use nontrivial Knowledge Representation and Reasoning (KRR). These systems use full-scale implementations of traditional KRR ...

This paper presents a survey of research in controlled natural languages that can be used as high-level knowledge representation languages. Over the past 10 years or so, a number of machine-oriented controlled natural languages have emerged that can be ...
