Bilingual Lexical and Conceptual Memory
Bibliographic record
Abstract
Because the majority of the world’s population speaks more than one language, in this chapter we consider that a “bilingual mental lexicon” can be viewed as the default, which may be a more accurate way of exploring lexical and conceptual memory. We transition to examine how concepts and words are represented in the mind, with a particular emphasis on the dynamic, developmental nature of word-to-concept mapping and the distributed, overlapping characteristics of semantic representations. Against this background, we review several theoretical models of word processing – including word recognition, production, and translation. The first set of models includes the Word Association Model and the Concept Mediation Model. We then discuss another set of models that offer a more detailed account of the conceptual system by emphasizing the degree of overlap that exists between conceptual representations in the two languages. In the last section of the chapter, we review two localist-connectionist models: the BIA/BIA+/BIA-d and the Multilink Models.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
