What is recorded here?
Mapped query and document-title letter-n-gram features through deep nonlinear projections and trained cosine-similarity ranking from clicked-versus-sampled document pairs.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
Inherits latent semantic retrieval and discriminative click models; word hashing has collisions and click supervision is a relevance proxy, not semantic truth. Original evaluation ranks document titles, not guaranteed full-document understanding.
