TEXT GRAPHS: ACCURATE CONCEPT MAPPING WITH WELL-DEFINED MEANING
Esko Nuutila, Seppo Törmä · 2004
Text graphs are special kind of concept maps that can be used in domains where accuracy and well-defined meaning are important. This sort of accuracy is often needed in technical domains like computer science, or whenever a detailed understanding of some complex structural constructions or causal interactions is required. Like traditional concept maps, text graphs are based on few primitive constructs and are thus easy to learn. Unlike traditional concept maps, text graphs allow accurate representation of non-binary relations and relational concepts as well as general propositional information. A text graph can be automatically translated to a set of natural language sentences that people can naturally attach a meaning. The set of sentences is called the text expansion of the graph. The propositional meaning of a text graph - i.e., what the graph asserts about the relationships of concepts - is the same as the meaning of its text expansion. To make text graphs a practical and usable notation, we have developed a text graph editing tool TGE. Category: Full Paper
