| Abstract(in English) | In this paper, a new logical model for structured documents enriched with OIDs and atomic value literals is presented. Such enriched text is named as "paratext". Paratexts are logically viewed as consisting of two parallel layers. On the "upper" layer, ordinary text (i.e. a linear sequence of character strings) is placed, while the "lower" layer holds an array of OIDs and literals. Each OID or literal on the lower layer is associated with a contiguous substring of the upper layer text, and represents the semantics of the associated substring. We have also designed domain-specific functions for this document model. Using the functions, we can express queries which go back and forth between the two text layers. For example, a query language with those functions can express a query such as "Retrieve news articles which mention Japanese companies in its body." |
