KnowledgeChunk structure
connected to the kc database.See: Description
| Class | Description |
|---|---|
| Document |
Representation of the source of a
KnowledgeChunk extraction. |
| DocumentExtraction |
Representation of an extraction process as a link between a
KnowledgeChunk and
a Document. |
| KnowledgeChunk |
Main class of the
kc framework, representation of a knowledge chunk. |
| Predicate |
This class represents a property value (or an inferred property value) attached to a
KnowledgeChunk. |
| Term |
Representation of a keyword of a
KnowledgeChunk with associated relevance and frequency. |
| TermTransformation |
Representation of a transformed form of a term (used for terms belonging to the KnowledgeChunk terminological
equipment).
|
| Type |
Representation of a class of a
KnowledgeChunk: could be an asserted class or an excluded class. |
Contains all necessary classes to represent and manage a KnowledgeChunk structure
connected to the kc database.
The main class of this package is the KnowledgeChunk class, exposing methods for
Knowledge Chunk management. This class represents a unit of knowledge (everything that can be represented with
an URI is a KnowledgeChunk) extracted from structured data repositories (RDF, Linked Data...) and
contains information about the source of the extraction (classes Document and
DocumentExtraction), the properties of the current kc, its types and its terminological equipment.
A better explanation is needed for the Predicate class: this is a representation of a path of properties in a knowledge graph
where belongKc is the starting node, p1 is the first edge (property) in the path, pn is the last property
and valueKc is the last object in the path (if the last object is a literal then valueKc will be empty and the value will be in
the value field).
All represented classes are associated with an xml mapping file (contained in the same package)
defining database mappings for Hibernate purposes. The subpackage session contains all
necessary classes to manage the database session (take a look at the package description for
more information).
The document config/kcDatabaseConfiguration.xml contains the database connection paremeters (such as URL, database name and database type).
