Abstract

Presents a new application for retrieving news from a large electronic bank of newspapers. Specifically, the application is intended to manage past issues of newspapers in such a way that users are able to draw up chronicles and trends about reported topics. Focuses on modelling the structure and temporal properties of newspapers. The resulting data model is object-oriented and uses metaclasses to cope with all the requirements of the application. The proposed system is then completed with both a Document Definition Language and a temporal Document Retrieval Language. The former allows the user to declare all the features supported by the data model. For the latter, outlines some query-processing strategies
