Sebo世譜 세보BETA]
Medieval and Early Modern Korean Kinship Workbench. Node and edge tables mapped back to the passage each was read from. Every identification carries its agent and its date; corrections are appended to a ledger and retired identifiers are never reissued.
The Andong Kwŏn Genealogy of 1476安東權氏成化譜 안동권씨 성화보]
A digital critical edition. The oldest extant comprehensive Korean genealogy, edited from the Academy of Korean Studies facsimile, with an inspection apparatus that checks the structured data against the original leaf by leaf.
Koryŏ Epitaphs高麗墓誌銘 고려묘지명BETA]
A structured corpus in five parallel layers. From the reading of the stone to the extracted relations, with a non-destructive overlay: no layer above may alter the layer beneath it, and the reading of the stone is never rewritten.
Closure通婚圈 통혼권ALPHA]
A computational experiment on marriage-circle closure. Whether tightly closed in-group marriage gave way to more diffusely embedded ties, tested against the Sŏnghwabo edition. The first run did not support the hypothesis and is published as it stands.
Sources
The historical corpora these works are made from, and what each contributes. The meter is that source's share of all 35,036 records in Samhan — one tally per ten per cent — so the weight of the Sŏnghwabo against the rest is visible rather than asserted. 13 corpora are configured; the 6 that currently contribute records are below.
