A unified context-aware content archive system allows enterprises to manage, enforce, monitor, moderate, and review business records associated with a variety of communication modalities. The system may store an information infoset derived or inferred from one or more documents representing communications according to the variety of communication modalities as interaction transcripts. An interaction transcript represents interactions between participants through the documents rather than the documents themselves allowing for derivation or inference of communication events, chronologies, and mappings to be stored in a common data structure. In one aspect, events correlation is provided between participants of communications that can be established by general time series analysis for the purposes of extracting meaningful statistics and interaction contexts and other characteristics of data. In another aspect, chronological mappings are provided of conversations between an established start and end time frame.
