Entities and Associations
Automated Entities
This toolkit element passes the document text to an external extraction engine to return entities and associations and occasionally metadata.
IKANOWS supports the following feature extraction engines:
- Textrank* ("textrank")
- OpenCalais* ("opencalais")
- AlchemyAPI** ("alchemyapi")
- AlchemyAPI-metadata** ("alchemyapi-metadata")
- salience* ("salience")
- regex* - a mechanism for converting regexes into entities from text or metadata ("regex")
*requires a text extractor beforehand.
**includes its own built-in text extractor, though can run behind an alternative text extractor also.
For more detailed information, see section Feature extraction.
Manual Entities
This toolkit element enables the generation of one or more types of entities based on the document or content metadata. The expressions default to replacement strings, or $SCRIPT(...) can be used to return a string using javascript.
For example, you can specify the entity fields from the imported metadata using $metadata. You can also iterate over metadata arrays to populate entity fields.
For more detailed information, see section Manual entities.
Manual Association of Entities
This toolkit element enables the generation of one or more types of associations between existing entities based on the document or content metadata. the expressions default to the replacement strings, or $SCRIPT can be used to return a string using javascript.
For example, you can specify the associations fields from the imported metadata using $metadata. You can also iterate over metadata arrays to create associations.
For more detailed information, see section Manual entities.
