Semantic Organization at Logos

the letter Lthe letter Othe letter Gthe letter Othe letter S ... organizing the world's Biblical information

Why Topical Analysis?

The Logos Controlled Vocabulary (LCV)

LCV Example: Deceit

COULD USE A BETTER EXAMPLE HERE. Fill out with other relationships
This organizes knowledge about language and subjects in biblical studies

Newer LCV Features

Connecting different datasets

Connecting Concepts to Terms and References

Deriving term-concept connections
ConceptAn item from the LCV (a "topic")
BookTraditional container for content
ArticleSubject-oriented unit of prose from a book
TermA "word" from an article
ReferenceA Bible reference term

The LCV Corpus: Overview

Resources by term count and reference percentage
Here i've combined books in a series: elsewhere in the counts, they're considered separate books

Breadth of Article Sources for Concepts

Learning Importance: with 13k concepts, need a way to rank
Binned number of sources per concept
Zeros are either rare people or cases where we need to merge. There are no "true" zeros.
The large majority have < 10 sources
So one definition of "important" is "broad"

Distribution of Terms for Concepts

Number of terms per concept
Another definition of "important" is how much is written about it
I didn't freehand this! Gives some confidence that scale is helping here.
Other measures we don't yet have data for: popular (search, or topic guide), "significant" according to some other standard. But breadth and term count are good cross-book approximations.
