Biographical Timeline Generation
Popular entities often possess hundreds of temporal relations within large-scale multilingual knowledge graphs.
We tackle the problem of providing an overview of relevant temporal information for an entity of user interest by the generation of biographical timelines using distant supervision methods.
EventKG+BT
EventKG+BT - Person Biography TimelinesBenchmark Description and Example
We adopted an automatic approach to generate our benchmark for biographical timelines. We have extracted entities and temporal relations contained in two biographical sources (Biographies: thefamouspeople.com and biography.com, and Wikipedia abstracts) and mapped them to the temporal relations in EventKG using an automatic procedure involving source-specific heuristics. Temporal relations extracted from the biographical sources are considered relevant. More details about the benchmark and its generation can be found in our paper.
In our benchmark which can be downloaded below, each entry shows an entity, a relation and the relevance label per biographical source. In the following example, the fact that Sarah Paulson starred in "Jack & Jill" between 1999 and 2001 was rated as relevant timeline entry for Sarah Paulson extracted from biography websites.
| Attribute | Description | Example Value |
|---|---|---|
| entity_label | Label of the timeline entity in the English Wikipedia | Sarah_Paulson |

| connected_entity_label | Label of the connected entity in the English Wikipedia | Jack & Jill |
| connected_entity_id | Label of the connected entity in the English Wikipedia | entity_5536831 |
| start_date | Start date of the temporal relation | 1999-09-26 |
| end_date | End date of the temporal relation | 2001-04-15 |
