COLUMN

The column rule identifies a column in a table either by index or by containing evidence

Score calculation

Scores its given weight if all its children occur in a particular column

Evidence calculation

The evidence is the set of phrase ranges describing the columns (note these are typically disjoint phrase ranges - so the count of phraseranges does not equal the count of columns).

Attribute information

• any common attribute
• COLUMN - The index of the column (starting at 1)
• TABLE - The index of the containing table (starting at 1)

Children restrictions

Any rule other than those restricted to a specific parent

Example 1

The following rulebase fragment

<column>
    <text data="Shareholders" />
</column>

Would fire for any columns in a detected table which contain the text “Shareholders”

Example 2

<column column="2" table="1" />

Fires with evidence for the second column in the first table detected in document.

Example 3

<column column="2" table="2-5" ><text data="something" /></column>

Fires with evidence for the second column in tables 2 through to 5 if that column contains “something” in it.
