The theme of this paper is to produce a coherent interpretation of texts (newspaper articles) by making their argumentation structure explicit. The method applied is the recognition of certain patterns in the text. These patterns are essentially strings of words. That means the algorithm exploits certain features of the language used to produce cohesive texts (e.g., either/or constructions). These structures are taken as an explicit expression of the underlying argumentation. The proposed approach seems to be related to the work of Lehnert [1], but she is never mentioned.
Since work on text (as opposed to sentence) understanding is still in its infancy, the theme of the paper is a very interesting one. But one has to wait for an implementation of the proposal (plus extensive tests on newspaper texts) before an evaluation seems possible.
