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.
Converting contract provisions into multi-dimensional risk representations and extracting negatively correlated clause clusters for automated risk assessment
Enterprise contract review is still heavily manual in many organizations. We present a mathematical framework that transforms legal clauses into dense risk vectors `r_i in R^d`, builds inter-clause correlation matrices, and extracts negatively correlated clause clusters associated with adversarial or misaligned provisions. In evaluated M&A due-diligence workflows, the approach reduced review time by 73%, identified 94.2% of material risk clauses flagged by human reviewers, and surfaced 31% more cross-clause risk interactions than baseline review processes.
