normalize_company_name() previously applied German
conventions only. It now covers German, French, Italian and
English, which is what multilingual registers such as the Swiss
one require.
lang argument on
normalize_company_name() and
match_companies(), accepting any of "de",
"fr", "it", "en". Defaults to all
four; narrow it for single-language data to strip fewer tokens.
The default therefore strips more than in 0.1.x — pass
lang = "de" for the old scope.sarl, sasu, eurl,
societe, srl, snc,
scarl, societa, llp,
incorporated, succursale,
niederlassung, …).company_name_stopwords() returns exactly which
tokens are stripped for a given set of languages, so the normalizer can
be audited.Société and Sàrl were previously never
recognised on the first pass, because the patterns were matched against
the still-accented string.normalize_company_name() is now
idempotent — applying it to its own output is a no-op, so one
pass always suffices. This follows from the ordering fix above:
previously Nestlé Sàrl became nestle sarl on
the first pass and only lost sarl on the second, so callers
had to re-normalize in a loop until the result stopped changing.
Such loops can now be replaced by a single call. A
regression test locks the property in.S.A.R.L. becomes sarl (and is stripped)
instead of four stray letters s a r l. Dots after
multi-letter tokens still act as separators, so Co. KG is
unaffected.L'Oréal and
Loreal both normalize to loreal, and
McDonald's gives mcdonalds rather than
mcdonald s.Deutsche Bank still normalizes to
deutsche bank, not bank.deutschland and germany). They identify a firm
as often as they pad it: removing them turned Credit Suisse
into credit and Air France into
air, either of which can then exact-match an unrelated
company. Since a spurious exact match is trusted and never reaches the
fuzzy stages or the LLM validator, keeping them is the safer default.
Structural branch markers (Niederlassung,
Succursale, Filiale, Standort)
are still removed.extra_stopwords argument on
normalize_company_name() and match_companies()
for corpus-specific filler — use it to strip geography anyway,
e.g. extra_stopwords = c("deutschland", "schweiz").normalize_company_name() is lossy by design:
"Meier GmbH" and "Meier AG" both become
"meier". Previously match_companies() aborted
whenever normalization produced duplicate dictionary names, which made
it unusable on real dictionaries without hand-written pre-cleaning.
match_companies() now collapses
duplicate normalized names instead of aborting. Each group is matched
once against a representative row, and no original row is lost:
dict_id in the result is the representative (first) id
of the group.dict_id_all column lists every id in the group,
separated by "|".n_dict_ids column reports the group size
(1 when unambiguous).dict_crosswalk() returns the mapping from every
original dictionary row to its representative, so collapsed entries
always remain traceable.expand_matches() expands a result to one row per
original dictionary row, recovering the source strings behind a
collapsed group.on_duplicate argument. The default
"collapse" is the behaviour above; "error"
restores the previous strict abort.NA after normalization are
now dropped with a warning. Previously an empty string could “exactly
match” every other empty string, producing spurious matches.dict_norm and query_norm arguments let
you skip normalization on either side when the input is already
clean.match_companies() now returns query_name
and dict_name alongside the ids, so the result is readable
(and ready for validate_matches_llm()) without joining the
inputs back on. The set of returned columns has changed; code
that relied on the previous three-column output may need
updating.match_type column was referenced before it was created).
All engines now return a consistently typed empty result.block, fts_q) to their inputs by
reference.LazyData from DESCRIPTION (the
package ships no data/ directory); added URL
and BugReports. Fixed a dead reference URL and retitled the
package, which is no longer German-only.validate_matches_llm enabling it to connect to local LLM
instances (like Ollama or LM Studio).engine argument allowing choice between
"azure", "openai", or
"local".validate_matches_llm writes to
tempdir() by default.These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
