| 1 | 12 | h1. Text annotation |
|
|---|---|---|---|
| 2 | |||
| 3 | Issue #2079 |
||
| 4 | |||
| 5 | Text annotation has been on our radar for some time now so I created an issues to discuss how we can proceed. |
||
| 6 | Basically it's about linking entities (actors, places, ...) to specific parts of a text, instead of just linking them to the whole text like it is possible currently. |
||
| 7 | |||
| 8 | h2. Scope (for the first version) |
||
| 9 | |||
| 10 | * It would be used at *Source* (E33) and their translations |
||
| 11 | * Only already linked entities are offered |
||
| 12 | * No overlapping annotations |
||
| 13 | |||
| 14 | h2. User interface |
||
| 15 | |||
| 16 | We need a tool for users to annotate. Although difficult, text changes and annotations should be doable in one form element. |
||
| 17 | |||
| 18 | *Advantages* |
||
| 19 | * Easy to use |
||
| 20 | * It's not possible for users to "break" things |
||
| 21 | * Concurrent changes can be avoided with already implemented functionality |
||
| 22 | * Maybe take a look at APIS implementation: https://github.com/acdh-oeaw/apis-highlighter-ng |
||
| 23 | |||
| 24 | h2. Information storing |
||
| 25 | |||
| 26 | We will save the information in an extra database table. Draft for fields: |
||
| 27 | |||
| 28 | * *id* (int, required) generic internal database identifier |
||
| 29 | * *source_id* (int, required) |
||
| 30 | * *entity_id* - (int, required) the entity is linked in the annotation, e.g. actor, place, artifact, ... |
||
| 31 | * *link_start* (int, required) |
||
| 32 | * *link_end* - (int, required) or maybe the length? |
||
| 33 | * *user_id* - (int, not required) to track who added it |
||
| 34 | * *text* - (text, not required) a kind of description field for text information, maybe think about the name, e.g. annotation, description, text, ... |
||
| 35 | |||
| 36 | *Advantages* |
||
| 37 | * We can guarantee that there are no orphaned links |
||
| 38 | * It can than be used to e.g. be presented as HTML, TEI, "Web Annotation Data Model":https://www.w3.org/TR/annotation-model/, ... |
||
| 39 | |||
| 40 | h2. Topics to discuss |
||
| 41 | |||
| 42 | * How to deal with text changes in already annotated text |
||
| 43 | * How to remove text annotations (maybe showing a list with delete buttons)? |
||
| 44 | |||
| 45 | h2. Time frame |
||
| 46 | |||
| 47 | Ideally we have a working basic version at the end of 2024 and can refine it in 2025. |
||
| 48 | |||
| 49 | h2. Ideas for future versions |
||
| 50 | |||
| 51 | * Offer links to external reference systems (e.g. GeoNames) which we would use to create new entities on the fly (using available meta information, creating links to reference system, ...). Interesting but a lot of work. |
||
| 52 | * A tool to find possible annotation candidates providing a result list to annotate multiple occurrences in one go |
