Telecom Knowledge Base

Knowledge graph for the telecommunications industry — wikidata entities + SDO standards catalogs, in flat tabular form (one row per subject/statement/qualifier triple).

At a glance

  • 4,679,018 rows, 301,949 distinct subjects, 16 columns
  • 162 MB parquet (zstd)
  • File ordered to put leading telcos (Vodafone, Deutsche Telekom, Verizon, Orange, BT…), then equipment vendors (Nokia, Ericsson, Huawei, Cisco, Qualcomm…), then headline 3GPP specs (TS 38.211, 23.501, 24.501…), then famous IETF RFCs (RFC 791 IP, RFC 793 TCP, RFC 9000 QUIC…), then telecom patents — at the very top of the file. The rest follows by source then numeric Q-ID.

Schema (16 columns)

column meaning
statement_id wikidata statement ID; synthetic md5 for non-wikidata sources
source wikidata / IETF / 3GPP / ITU-T / Bluetooth / CableLabs
subject_id wikidata Q-ID or STD:<SDO>:<id>
subject_label canonical English label
subject_description English description
subject_instance_of_ids pipe-separated P31 Q-IDs
subject_instance_of_labels pipe-separated P31 labels
property_id P-ID (P31, P50, P577, P1476, …)
property_label property label
value_id Q-ID or string value
value_label value label
value_type wikibase-entityid / string / time / monolingualtext / url
qualifier_property_id qualifier P-ID (may be empty)
qualifier_property_label qualifier label
qualifier_value_id qualifier value
qualifier_value_label qualifier value label

A statement with N qualifiers becomes N rows sharing the same statement_id; a statement with no qualifier is one row with empty qualifier fields.

Wikidata side

All wikidata properties of every kept subject are preserved — no property selection. The pipeline filters out entities (e.g. radio-personality humans, ships, off-topic content stubs) but never drops individual statements from a kept entity.

Build summary: 75 hand-curated telecom anchor classes → P279 BFS walk → 6,448 classes → P31 entity scan → property-based expansion (P452 / P101 / P106 / P921 / P136 / P1056) → anchor cascade (P108 / P127 / P137 / P749 / P176 / P361 / P488 / P169 / P3320 / P710) → concept-anchor patch (MIMO, OFDM, RSRP, IEEE 802.11n/ac/ax, Shannon-Hartley, AWGN, Friis, …) → weak-area patch (pioneers, ITU-T codecs, country regulators, SDN/NFV, mobile OS) → cleanup filters → 287,535 wikidata subjects.

Standards side

SDO Source Notes
IETF rfc-editor.org/rfc-index.xml full metadata: title, authors, year/month, status, abstract, obsoletes/-by, keywords
3GPP 3gpp.org/ftp/Specs/archive/ + 3gpp.org/dynareport 91 % titles + last_modified + per-version date
ITU-T itu.int/itu-t/recommendations per series std_id + series
Bluetooth SIG bluetooth.com/specifications/specs/ title + url
CableLabs / DOCSIS cablelabs.com/specifications title + url

Standards rows use a 13-property wikidata-aligned subset (P31, P1476 title, P577 date, P361 part-of, P953 URL, P50 author, P155/P156 follows/-by, P393 edition, P348 version, P407 language, P5008 status, P1683 abstract) — a deliberate schema alignment to make standards joinable against the wikidata rows. Native per-SDO catalog parquets with all original fields are preserved upstream.

Not ingested (JS-rendered SDO catalogs): ETSI, GSMA, IEEE Get Program.

Subject-ID convention

  • Q… — wikidata entity
  • STD:IETF:RFC0791, STD:3GPP:TS_38.211, STD:ITU-T:G.711, STD:Bluetooth:…, STD:CableLabs:… — standards

Synthetic instance-of classes for SDO docs without wikidata Q-ID counterparts: SYN:3GPP-TS, SYN:3GPP-TR, SYN:BT-SPEC, SYN:DOCSIS.

Loading 

import pyarrow.parquet as pq, pyarrow.compute as pc

# stream
pf = pq.ParquetFile("telecom_kb_v15.parquet")
for batch in pf.iter_batches(batch_size=50_000):
    for row in batch.to_pylist():
        pass

# filter examples
t = pq.read_table("telecom_kb_v15.parquet")
verizon = t.filter(pc.equal(t["subject_id"], "Q467752"))
ietf    = t.filter(pc.equal(t["source"],     "IETF"))

Reconstruct a per-entity view by grouping on subject_id (+ statement_id).

Caveats

  • Wikidata side reflects a 2026-Q1 dump; later additions are absent.
  • Standards side is metadata only (titles / dates / versions / URLs / authors / obsoletes-chains), not full spec text.
  • Wikidata coverage of individual standards documents is sparse: 0 3GPP TS docs by exact label, ~95 RFCs by exact RFC NNN label (plus ~1,700 by content-title via Q212971 RFC class), ~572 ITU-T recommendations. The standards-side rows are largely net-new vs wikidata.
  • Some cascade noise remains (non-telecom patents owned by Samsung / Qualcomm etc.) — documented in audits but kept per scope.
