The Theory of Index Nodes: Distributed Gateways Governing the Activation Direction of Semantic Clusters

This record contains the English and Japanese versions of the same conceptual essay. The paper proposes the concept of the “index node” as a foundational extension of Semantic Cluster Theory. It argues that human meaning-understanding, association, context formation, creativity, social asymmetry, and identity are not generated directly from isolated words or dictionary definitions, but from distributed index nodes formed through bodily experience, life history, social position, institutional pressure, and environmental contact. An index node is defined as a distributed gateway structure that governs the activation direction of semantic clusters. The paper distinguishes index nodes from ordinary central nodes within semantic clusters, treating them instead as bodily, procedural, and life-historical structures that precede and guide later linguistic or conceptual activation. The essay further examines life-stage resegmentation, institutional stabilization and closure, environmental index transfer through leisure and walking, and the limits of LLM personalization. It argues that LLM personas are not subject-specific histories, but local biases in distributions constructed in response to input context. The paper also analyzes why multi-instance LLM verification requires differentiated index-node configurations rather than merely repeated computation. The Japanese file is included as a parallel-language version of the same work, not as a separate publication. 本レコードには、同一論文の英語版および日本語版を収録している。日本語版は別論文ではなく、同一内容の並行言語版として含まれている。
