Build a master skills list with metadata and diffusion classification

Aggregates skill metadata (reuse type, flag columns) and merges with diffusion scores. The ESCO reuse type labels are translated to Italian.

Usage

build_skillist(skills, diffusion)

Arguments

skills

A data.table of skill occurrences with required columns escoskill_level_3, esco_v0101_reusetype, esco_v0101_green, esco_v0101_language, and the optional columns pillar_softskills and esco_v0101_ict.

diffusion

A data.table as returned by compute_skill_diffusion(), with columns escoskill_level_3, N, tf, idf, diffusione.

Value

A data.table with one row per unique skill, including metadata columns, the Italian type label (tipo), and diffusion scores. The columns pillar_softskills and esco_v0101_ict are always present, and are NA_integer_ when absent from skills.

Details

The tipo classification derives from esco_v0101_reusetype alone; pillar_softskills and esco_v0101_ict are descriptive pass-through flags. They are optional because the Lightcast data_v2 delivery consumed through itaposts no longer supplies them: data read with read_oja_itaposts() yields NA in both columns, while legacy sources that still carry the flags pass them through unchanged.
