Source: R/causal_corpus.R
causal_corpus_scielo.Rd

Calls the SciELO ArticleMeta REST API (no account needed) and returns a tidy data frame of abstracts ready for LLM extraction via causal_llm_ingest_corpus(). Results are deduplicated by DOI / title and filtered to articles that expose an abstract.

Usage

causal_corpus_scielo(
  query,
  max_results = 50L,
  from_year = NULL,
  to_year = NULL,
  host = "articlemeta.scielo.org",
  timeout_sec = 120
)

Arguments

query

Character search string passed to the ArticleMeta full-text search (q=).

max_results

Integer cap on the number of articles fetched.

from_year, to_year

Optional integer year filters (inclusive).

host

Endpoint host (default "articlemeta.scielo.org"; override for mirror testing).

timeout_sec

Request timeout (seconds).

Value

A data frame with columns source, title, abstract, year, doi, url.

Examples

  cerrado <- causal_corpus_scielo("Cerrado soil organic carbon",
                                   max_results = 20)
  head(cerrado[, c("source", "title", "year")])
} # }
