Document-driven investigative tools

This is a collection of tools for ingesting, normalizing, indexing and tagging documents in the context of a journalistic investigation.

These tools are intended to be complementary to existing platforms such as DocumentCloud and analice.me.

Use cases

  • As a journalist, I want to store a list of documents that mention a person/org/topic so that I can sift through the documents.
  • As a journalist, I want to intersect sets of documents that mention people/orgs/topics so that I can drill down on the relationships between them.
  • As a journalist, I want to combine different types of facets which represent document and entity metadata.
  • As a data importer, I want to routinely crawl and import documents from a data source.
  • As a data importer, I want to associate metadata with documents and entities to allow advanced facets.

Basic ideas

  • An entity (such as a person, organisation, or topic) is always a search query; each entity can have multiple actual queries associated with it by means of aliases (tags?).
  • Documents can be anything, and there is no guarantee that dit will be able to display it - just index it. Document display is handled by DocumentCloud etc.
  • Documents matching an entity after that entity has been created yield notifications if a user is subscribed.

Existing tools

Installation

dit uses textract, which has external (i.e. non-Python) dependencies. See the install guide.
