Abstract : This article presents a theoretical study of an information retrieval model based on conceptual graphs. A conceptual graph oriented system (Elen) is chosen due to its close relation with information inference. A conceptual graph is a representative of the information inherent in the document and query. Graph operators can be used to determine whether a graph is a generalization of another graph; in which case the information carried by the graph is said to be about the information carried by the generalization of the graph. The retrieval mechanism of Elen is based on this sort of decisions. The retrieval mechanism is first mapped to a situated logic framework. Within this framework, the axioms that drive the retrieval process can be filtered out. The retrieval mechanism can then be compared with other approaches according to which axioms they are governed by. Using this method we can show that graph projection rules are indeed closely related to aboutness decisions. So, the effectiveness of the model can be examined, not by running experminents, but by mapping it appropriately into the framework.
