Abstract

fetched live from OpenAlex

Entity Linking (EL) consists in linking mentions in a document to their referent entities in a Knowledge Base. Current approaches fall into two main categories: local approaches, in which mentions are linked independently of each other, and global approaches, in which all mentions are linked collectively. Local approaches often ignore the semantic relatedness of entities, and while global approaches incorporate the semantic relatedness, they tend to focus only on directly connected entities, ignoring indirect connections which might be useful. We present a global EL approach that unifies the representation of the semantics of entities and documents--the probability distribution of entities being visited during a random walk on an entity graph--that accounts for direct and indirect connections. An experimental evaluation shows that our method outperforms five state-of-the-art EL systems and two very strong baselines.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
