Knowledge base

Connect the knowledge in a book.

PDF Craft desktop uses Wiki Graph Core to index PDF and EPUB text for search with links back to the source. For public entities, relationships, and summaries, take prepared text further with the standalone wg CLI.

From source material to a knowledge base

Preparation and indexing serve different purposes. You can inspect the text and the knowledge built from it.

  1. Prepare readable text

    Prepare PDF and EPUB text in PDF Craft. Other source formats can be converted to plain text with external tools before using wg; review complex extraction results against the original.

  2. Build the index

    In PDF Craft desktop, create a .wikg text index for a PDF or EPUB. The standalone wg CLI can also extract public entities, relationships, and evidence from prepared text.

  3. Explore and check

    Search across indexed documents and jump back to the source in PDF Craft. Use the CLI to explore entities and the passages supporting their relationships.

Go beyond a matching paragraph

A long document can mention the same subject in many places. Bring those clues together without losing the source.

Find a subject
Search the source text or find an entity mentioned in the document.
Follow connections
In the standalone Wiki Graph CLI, see how people, places, organizations, and concepts relate across chapters.
Check the evidence
Open the source passages behind an entity or relationship before relying on it.

Search in PDF Craft. Explore relationships with wg.

PDF Craft desktop

Build an index for PDFs and EPUBs, search across documents, and open the matching source location.

Standalone Wiki Graph CLI

Use wg to generate public entities, relationships, evidence, and summaries from prepared text, then explore their connections.

What to expect

PDF Craft desktop currently provides basic full-text indexing and source navigation. Entity relationships and summaries require the standalone wg CLI. Entity extraction focuses on public concepts that can be matched to Wikipedia or Wikidata; private names may be missed. Check important claims against the source. SDPUB's chapter reading graph is a separate reading experience.
