Behind the Curtains
How Does it Work
Depending on the indexing task, a tailored pipeline is applied.
- For large authority files used in archival and bibliographic indexing, vocabularies are transformed into mathematical representations of their semantic meaning using embeddings, enriched by the hierarchical relationships between terms. Each text fragment is analyzed, and the most relevant terms from the vocabulary are retrieved and ranked.
- For subject headings used in book indexing, a graph-based structure captures the hierarchy of terms. Large language models extract information from the text and navigate the vocabulary iteratively, identifying the most relevant nodes.
- Generative language models are optimised to capture the meaning of textual sources and summarise it in a compact text.
