How Asklaw Ensures 95% Citation Accuracy for Vietnamese Law

Quick Answer: Asklaw maintains a minimum 95% Article/Clause citation accuracy rate through a three-layer architecture: (1) daily synchronization of 166,000+ legal documents from vbpl.moj.gov.vn (the official Vietnamese Ministry of Justice database), (2) a mandatory P-E-V (Plan-Execute-Verify) pipeline that requires every answer to include a verifiable citation, and (3) a gold-50 benchmark of 50 reference questions with editor-validated answers. Every citation shown on Asklaw includes a direct link to the source document on vbpl.moj.gov.vn, allowing users to verify it in under 30 seconds.

1. Why citation accuracy matters

In legal research, a single wrong number — Article 138 instead of Article 139, Labor Code 2012 instead of 2019 — can produce real consequences. An employee relying on outdated provisions may lose maternity benefits; a company relying on the wrong clause may face administrative fines under labor enforcement decrees.

General-purpose large language models such as ChatGPT or Gemini suffer from a well-documented issue called hallucination: the model generates content that sounds confident but is not grounded in any source. For Vietnamese legal research, hallucinated citations are an unacceptable risk.

Asklaw is engineered to make hallucinated citations structurally impossible to surface. This is the core difference between Asklaw and a general legal chatbot.

2. Layer 1 — Official source from vbpl.moj.gov.vn

Asklaw's entire legal corpus is sourced from the National Legal Documents Database operated by the Vietnamese Ministry of Justice (vbpl.moj.gov.vn). This is the official source under the Law on Promulgation of Legal Documents 80/2015/QH13 (as amended by 63/2020/QH14).

The Asklaw system synchronizes 166,000+ legal normative documents (VBQPPL), including Laws, Codes, Decrees, Circulars, and central-level Decisions. Each document is stored with its original metadata:

• Official document number (e.g., 45/2019/QH14)
• Issuing authority
• Promulgation date and effective date
• Current status (In effect / Partially in effect / Expired)
• ItemID linking to the original page on vbpl.moj.gov.vn

Every citation Asklaw renders resolves to the original ItemID — no intermediary, no rewritten summary of the Article/Clause text. The document is displayed as officially promulgated.

3. Layer 2 — The P-E-V (Plan-Execute-Verify) pipeline

Instead of letting an LLM answer directly, Asklaw applies a mandatory three-step pipeline:

Plan: The system analyzes the question, identifies the legal domain involved (labor, land, business, etc.), and lists the documents that must be retrieved.

Execute: Articles/Clauses are retrieved from the corpus using vector search (BGE-m3, 1024 dimensions) combined with full-text search. This step returns candidate Articles with relevance scores.

Verify: Before the answer is displayed, the system cross-checks every citation against the source document in the corpus. If an Article/Clause is referenced but does not exist in the source, or has already expired, the system refuses to serve the answer and asks the user to rephrase.

This mechanism also aligns with the transparency obligations imposed on AI providers by the Vietnam AI Act 2026 — AI output must be traceable to its source data.

4. Layer 3 — The gold-50 benchmark

For objective measurement, the Asklaw editorial team maintains a gold-50 evaluation set: 50 reference questions across five topic clusters (labor, land, family, business, expat). Each question has a validated answer specifying the correct Article, Clause, Law, and vbpl.moj.gov.vn reference page.

Each time a new model or pipeline change is released, the full gold-50 set is rerun and four metrics are measured:

1. Citation accuracy — share of cited Articles/Clauses matching the reference answer
2. Coverage — share of questions answered rather than refused
3. Warning rate — share of answers issued with a warning (e.g., "this Article has been amended")
4. Refusal rate — share of refusals aligned with policy

The internal standard is citation accuracy >= 95%, coverage at 100%, and warning rate <= 5%. If a release drops any metric below threshold, the release is blocked by internal QA.

5. A concrete example — verify in 30 seconds

Suppose a user asks: "How long is maternity leave in Vietnam?"

Asklaw answers:

Under Clause 1, Article 139 of the Labor Code 2019 (Law No. 45/2019/QH14), a female employee is entitled to a total of 6 months of maternity leave before and after childbirth, with no more than 2 months taken before childbirth.

Source: Article 139, Labor Code 2019 — vbpl.moj.gov.vn

The user clicks the link. The vbpl.moj.gov.vn page opens to Article 139 in its original wording. Total verification time: under 30 seconds.

This is the core distinction: with Asklaw, the user does not need to trust the system internally. Every answer ships with an independent verification window pointing back to the official state source.

6. Why it matters in practice

A high citation-accuracy bar produces three concrete benefits:

For Vietnamese residents: Reduces the risk of applying outdated provisions and losing entitlements (maternity, severance, divorce, inheritance).

For SMEs: Reduces the risk of administrative fines caused by misreading labor, tax, or registration rules.

For expats: Provides verifiable source documents when interacting with state agencies on work permits, TRCs, or business setup — instead of relying on uncited summaries.

7. A transparent commitment

Asklaw does not promise 100% accuracy — no AI tool should. Asklaw does commit to transparency on three points:

• The gold-50 benchmark numbers are published on the /transparency page
• Every citation links back to the original document on vbpl.moj.gov.vn
• When a document has expired or been amended, the system surfaces a clear warning

Users can independently audit Asklaw's reliability by verifying any citation in under a minute.
