Enron Concepts

An example extraction of concepts, themes, entities, and relationships from a sample of the full Dossier Space corpus, linking each finding to its source and distinguishing explicit statements from inferred concepts. This test used approximately 20 emails, producing a concept list with definitions, supporting excerpts, and a few examples of ambiguous classifications. This required reading message text, beyond the metadata-only scope, leaving attachments excluded.

Nodes are analyst-defined concepts; arrows are labelled relationships supported by the cited records. A connection is not proof of causation. C09, C10 and C11 remain separate rather than forcing a connection unsupported by this sample.

Four inherited records were selected because S23 found substantive text. The new records are therefore an extension sample, not a new probability sample. All 19 lack exact normalized-body duplicates and repeated sampled Message-ID values. That does not establish semantic independence: B05/B10/N05/N06/N07/N08/N11/N15 include quoted or forwarded correspondence.

Shared themes across records are not corroboration of the same event. No thread expansion was performed.

Dossier Concept Simulator is available to signed-in administrators.

Exploring the simulator

  • Map: click a concept card for definitions and support. Click a relationship number or use the relationship list to see the typed link and its interpretation limit.
  • Evidence: inspect the currently visible excerpts, statement types and source locators.
  • Sample simulator: switch to the original four records, restore all 19, or include/exclude records individually. Selected records may still be hidden by the mailbox filter.
  • Find a concept: matches concept labels and definitions, not full email contents.
  • Mailbox: restrict support to Bailey, Rapp or Pereira.
  • Records per concept: require more distinct sampled records before a concept appears.
  • Hide forecast / possibility excerpts: removes excerpts explicitly typed as forecasts or possibilities; other types, including questions and uncertainty, remain visible.
  • Restore all: resets the sample and filters. Browser refresh also resets them.

Concept definitions and sample support

ConceptDefinition / boundaryRecords
Agreement lifecycleDrafting, revising, signing or assessing permissions under an agreement; distinguish a proposed action from completion.B05, N01, N07, N08, N10
Document availability and completenessWhether required copies or document sets are available; absence of a copy is not absence of an agreement.B05, B10
Follow-up and handoverRequests, reminders, responsibility assignment and onward document delivery; intentions are not completed transfers.B05, B10, N01, N05, N10
Identity and communication routingResolving recipients or asking which communication route to use; a routing question is not an established rule.B10, N13
Trade and volume reconciliationReviewing trades, deal status, pricing or scheduled versus allocated volumes; underlying records remain unverified.B02, N05, N11
Regulatory response and filingPreparing a response or discussing which contracts should be filed; these are participants’ positions, not legal determinations.N06, N07
Scheduling and coordinationArranging, postponing or cancelling calls, meetings or activities; tentative timings remain tentative.N03, N04, N06, N07, N12, N14
Employee learningInvitations to structured learning; an invitation does not establish attendance or case-specific advice.N04
Distress expectationsStatements forecasting bankruptcy, default or employment consequences; preserve uncertainty and prediction time.N15
Third-party newsExternally authored news circulated in a mailbox; receipt does not establish the recipient’s belief or independent corroboration.N09
Time-exception reportingA report about exceptions for a reporting period, including explicit reports of none.B28
Personal and civic communicationSocial, leisure or community communications; do not force these into a business-risk interpretation.N02, N12, N13, N14

Where meaning would be lost by keyword-only coding

  • N08: a question about contractual control is answered “No, unfortunately not.” Coding only the question would reverse the meaning.
  • B05: a missing executed copy is not proof that the agreement was unexecuted.
  • N05: a quoted list says a trade may be booked incorrectly. This remains an unverified possibility.
  • N15: bankruptcy and defaults are forecasts by the sender, not verified events. No attempt was made to validate historical outcomes.
  • N09: a newsletter is third-party reportage. Its presence does not prove that the recipient read it or shared its claims. It is coded at the news-provenance level; all newsletter subtopics have not been exhaustively mapped.
  • N14: timing is tentative and pending approval. B28 explicitly reports no time exceptions.
  • N01: the outer sender fields are blank; Wendy is a body signature. Identity has not been resolved beyond that.

Limits and reproduction

This is convenience selection across three small archives, followed by deterministic ranking and recorded body screening. It is neither random sampling of the whole corpus nor a saturation or accuracy study. The text threshold favors longer messages and may exclude meaningful short ones. Personal messages and a newsletter were retained rather than replaced for business relevance. The concepts are not exhaustive.
