Entity Options

This section contains information on options that affect the behavior of entity detection. You are able to set the type of entity detected and whether anaphora resolution is use.

Suggest Edits

Required Entities

If set, only entities of the specified type (comma-delimited list) will be returned. Possible values are: Company, Person, Place, Sports, Product, Job Title, List, Regex, Pattern, Quote, Custom

Min/Max range

N/A

Default value

None

C API

SalienceOption oOption;
oOption.nOption = SALIENCEOPTION_REQUIREDENTITIES;
oOption.acValue = ;
lxaSetSalienceOption(pSession,&oOption);

.NET

SalienceEngine.RequiredEntities = string value

Java

Salience.Options.Entities.setRequiredEntities(string value)

Python

salience.setOption_RequiredEntities(session,string value, configuration ID)

Anaphora Resolution

When set to true (1), Salience will connect entities to pronouns.

What we call anaphora, you might call pronouns, and Anaphora Resolution means counting those pronouns as instances of the mentions they refer to. This is usually what you want, but you can turn this feature off if you prefer. Sometimes you're more interested only in how often a company or person was called out explicitly by name.

Min/Max range

0 or 1

Default value

1

C API

SalienceOption oOption;
oOption.nOption = SALIENCEOPTION_PERFORMANAPHORA;
oOption.nValue = ;
lxaSetSalienceOption(pSession,&oOption);

Default value

1000000

Entity Threshold

Controls how confident Salience must be to return an entity.
