Evidence-Linked Meeting Minutes: Structured Extraction with Mandatory Citation Chains

Every decision must cite its source — how MARIA Meeting AI eliminates hallucinated minutes through segment-level evidence linking

Traditional meeting minutes suffer from a fundamental trust problem: the reader cannot verify whether a recorded decision actually occurred in the meeting or was interpolated by the note-taker. MARIA Meeting AI solves this by enforcing mandatory evidence linking — every decision, action item, and summary section must reference specific transcript segments as evidence. This paper formalizes the evidence-linking constraint, presents the incremental summarization algorithm that generates minutes every 15 seconds during live meetings, and proves that the citation coverage metric converges to completeness as transcript length increases. In evaluated Japanese business meetings, the system achieved 94% citation coverage with zero hallucinated decisions.

契約リスクのベクトル化: 法務条項を計算可能なリスク表現へ変換する

条項を多次元リスク空間へ写像し、相関構造から見えにくい契約リスクを抽出する

契約レビューを条項単位の読解から、条項間関係を含む数理評価へ拡張する。リスクベクトルと相関行列を用いて、敵対的・非整合的な条項組み合わせを検出し、デューデリジェンスの優先順位付けを支援する。
