Deterministic communications analysis within e-discovery
QLCA: Quantitative Legal Communications Analytics
Within CloseVector's e-discovery workflow, QLCA turns communication timing, baselines, channel shifts, and response patterns into deterministic, reproducible, evidence-linked signals. It supports review and investigation without replacing professional judgment.

Communication timingMeasure intervals, response latency, silence, and event-linked changes.
BaselinesCompare observed patterns with the matter's own prior communication behavior.
Channel shiftsTrace movement among email, chat, SMS, voice, meetings, and attachments.
Response patternsConnect reproducible metrics to source records, timestamps, custodians, and run IDs.

Legal and E-discovery Applications
Deterministic communications analysis for review, investigation, and litigation

The Analytical Paradigm
Evidence-linked signals for review, investigation, and litigation
Signal-first
measure first, interpret second
Baseline comparisons
what changed, relative to what
Time-first
when did the shift start, how sharp was the break
Multi-channel telemetry
email, chat, SMS, voice, transcripts, attachments
The goal is not to replace professional judgment. The goal is to make behavioral patterns measurable and defensible.

A variance change can identify a review window; interpretation remains matter-specific and requires professional judgment.

Analytical Studies
16 buildable modules with hypotheses and outputs
Each study is a standardized analysis module that consumes canonical records and emits deterministic metrics, plots, evidence pointers, and run-stamped findings. Evidence pointers map each metric to record IDs (message IDs, recording IDs, transcript spans), timestamps, custodians, and extraction provenance, or to time-bounded void intervals when absence of communication is the signal. Narrative is optional and must anchor to evidence.
Deterministic means: given the same source records, configuration, and pinned tool/model versions, the pipeline reproduces identical metrics and evidence pointers. Narrative (if enabled) is generated separately (non-deterministic), labeled non-evidentiary commentary, and source-checked back to underlying records (citations to record IDs). Default is OFF.
NarrativeOptional: local narrative summarization (air-gapped; non-evidentiary; source-checked)OFF by default • source-checked to record IDs when enabled
