| Zusammenfassung: | Abstract: "This paper describes a knowledge representation scheme for knowledge about the contents of data (for example, 'text') and abstracted information of data. In the proposed scheme, the contents of data are initially represented by a kind of semantic network in which the case frame structure of the data is expressed explicitly, and abstracted information of the data which is extracted from the semantic network is also represented in the form of a semantic network. By step-by-step abstraction, abstractive layers of knowledge about the data are formed, the components of which are eventually linked with corresponding data The objective of the proposed scheme is to offer a general view of the contents of the data stored in an information retrieval system. In an interactive environment, it allows users to move as they wish from the general to the particular as well as to change the viewpoint of retrieval. Stored knowledge about the data serves as a phrase index for retrieval which is more desirable than a single keyword index as far as precision of retrieval is concerned. Since items of abstracted information which are common among the information of lower layers can be related to each other, some identification based on the relation makes it possible to locate information similar to the specified data. |
