| Search Interfaces | |
| Name Entitie Extraction | |
| Combination of Search Interfaces | |
| Conclusion | |
| Search in classical Digital Library (DL): keyword, classification, metadata | |
| What if we want to search for photographs, maps, major historical events? | |
| Search DL using characterizing attribute | |
| Brings us to our topic… | |
| Digital library is a good source for information | |
| Problem: how to access? | |
| Classical IR models don’t work well with long documents and other types of information (e.g. maps) | |
| Keyword | |
| Navigational Classification Hierarchy | |
| Digital Library for Earth System Education | |
| (DLESE) | |
| Timeline | |
| Perseus Project | |
| Informative Map-interface | |
| Perseus Project |
| Navigational Map-interface | |
| Alexandria Digital Library (ADL) |
Combination of Search Interfaces
| map, classification, time period | |
| Map provides navigation and specifies constraints | |
| Visual information about categories | |
| NE extraction adds new dimensions (DATE, LOC, NAME etc.) | |
| Search interface should be intuitive | |
| Visual techniques show the content of very long documents with different types of information |
