Regional web search engines provide users with spatially restricted web contents. We propose a time-specific regional web search engine, where users can retrieve both spatially and temporally restricted information from the Web, i.e. a description of a shop available at certain time in a certain region. Because there are many web pages containing descriptions of more than one geographic entity, a matching mechanism of spatial and temporal attributes is required. We used HTML tag structures to make matches between addresses and temporal interval expressions. Based on the extracted result, map-based visual interface was implemented. © Springer-Verlag Berlin Heidelberg 2005.
