Methodology and metrics

All figures are computed automatically from the official records. The definitions and rules are set out here.

Principles

There are no scores, rankings or “ratings” of MPs. The number of bills submitted or speeches made does not measure the quality of the work.
Every metric has a definition and a coverage status: complete, partial, not imported, no structured data. A zero with complete data is a verified zero.
We distinguish official links (stated by the source) from inferred ones (e.g. a vote linked to a bill from the text of its topic). Inferred links are marked in the interface.
The sponsors of a bill are not necessarily the authors of any particular text in the law; a proposal adopted in committee may not make it into the final text.
Historical affiliation (group, position) is determined from dated memberships as of the date of the event.

Identity of persons

parliament.bg issues a new identifier for each term of office. Terms are merged into one person by full name and date of birth. Roll-call votes are matched by full name within a National Assembly; speeches by first name and surname, only when the match is unambiguous.

Votes

For each MP the roll-call files contain “+” (for), “−” (against), “=” (abstain) or “0” (did not vote), and at registration “П” (present) / “О” (absent). “Did not vote” does not necessarily mean absent. The “adopted/not adopted” result is computed by a simple majority of those voting; special majorities are not modelled. The stage (first/second reading, procedure…) is determined from the topic. Procedural motions (e.g. for live broadcast) are not counted as proposals on bills. The registration code “Р” is not explained by the source; since those marked “Р” go on to vote, it is counted as present. The date and content of every file are checked against the sitting: when a file from another day or of another kind is attached to a sitting, the CSV version is used if it is correct; otherwise the roll-call results are not imported and the sitting is flagged with a data-quality note.

Absences

The National Assembly publishes a register of unexcused absences: from a plenary sitting or from a meeting of a particular committee. Absences for valid reasons are not recorded, so the lack of a record means “no unexcused absence recorded”, not necessarily presence. Records are shown in the timeline and in the calendar tooltips, but are not counted as activity. The source returns at most 100 records per request, so on the few days with more records (whole groups absent) the list is incomplete; the count is then a lower bound (“≥ N”) and the metric is marked as partial.

Declarations of assets and interests

The declarations come from the public register of the Anti-Corruption Commission and are shown by year, as filed, without corrections, currency conversion or summing across years. We do not reproduce spouses' income, the names of other persons or the exact addresses of properties (the municipality remains). The original file is linked to each declaration. MPs' pay is not published separately: it is set by the Rules of Procedure and is the same for everyone; the declarations state the annual tax base from employment income.

Council of Ministers

Posts come from the acts in the State Gazette: the National Assembly's decisions electing a cabinet or making personnel changes, and the President's decrees for caretaker cabinets. A post starts on the day of the act (or on the date of entry into force, if the decree gives one) and ends with the release or when the next cabinet takes office. The post is named as in the act.
Questions and interpellations name the addressee by first and last name only, and transcripts give the speaker's post and name. They are linked to the member of the cabinet with that name who was in post on the day, and only when there is exactly one. These links are inferred and marked as such.
The link to an MP profile is by full name (all three names) and is also inferred.
Pay is a calculation: a minister's salary equals that of the chair of a standing committee of the National Assembly (according to the Administration of the Council of Ministers). For the Prime Minister and the deputy prime ministers the amount is not published and is not calculated.

Cohesion, agreement and co-sponsorship

Group majority in a vote is the most common of “for”, “against” and “abstain” among the group's members who voted (from the official result by group). In a tie the group has no majority. Independents are not a group.
Cohesion = members voting with the majority / members voting. Only votes with at least 3 voting members are counted; “did not vote” is not a position.
Agreement between two groups = share of votes in which both have a majority and it is the same.
With the group majority (in the profile) = share of the MP's votes as a group member that match the group majority in the same vote; the MP's own vote is part of that majority.
Co-sponsorship: two MPs are linked if they are among the sponsors of the same bill. The network layout is automatic, and how close the dots are has no meaning of its own.

These are descriptive shares and counts, not an assessment of “loyalty” or of work; procedural votes count the same as all others.

Positions from speeches

This is a language model's estimate (Claude Sonnet 5.5), not a fact. For each MP and National Assembly the model reads a sample of their plenary speeches (at least 40 words each, spread evenly over time, up to 20,000 words) without knowing their name or party.
Three axes from 0 to 10, modelled on the Chapel Hill expert survey: economy (more state ↔ more market), values (liberal ↔ conservative) and foreign orientation (EU and NATO ↔ Russia, euroscepticism). When the speeches show no position, there is no score.
Each score has a confidence, a one-sentence explanation and up to two quotes. Every quote is checked word for word against the speech it comes from and links to it; quotes that cannot be confirmed are removed.
Topics and tone (on substance, confrontational, procedural) are shares of the speeches. The results are not ordered into a ranking.

Search

Search is full-text: every word entered must appear, and it is also matched as the start of a word („бюджет“ also finds „бюджета“, „бюджетът“), regardless of case. Transcript results are ordered from newest to oldest; speeches by the presiding officer are not indexed.

Deduplication

A bill with many sponsors counts once for each of them, and only once per sponsor, however many documents or stages it appears in. Proposals between first and second reading are counted by registration number.
