Overview

Based on the two basic types of search: keyword and conceptual, also offers you the possibility to further navigate in your searched results. You can explore:

• the retrieved document - as metadata and content
• the entities – as graphs in the knowledge base (aliases, linking to other entities, URI, further navigation to documents, etc.)

Document Detail

The Document Detail screen provides a detailed view of the document you have selected from the retrieved document results. It consists of two fields. The document feature list shows additional information (metadata) about the document and the Body field - the text of the document.

The example below displays the result of a Facets search for Barack Obama and Hamas.

Document features field

The document feature list provides the following metadata about the selected document: date, title, source (news agency), language, author, URL, key phrases (words or phrases considered characteristic of the selected document), and key entities (named entities that are statistically rare in the document set and therefore are considered to be particularly characteristic of the selected document).

Body field

The Body field displays the content of the retrieved document. All entities that were specified in the search criteria are marked as hyperlinks. If you follow these hyperlinks, you can see the entity description of the respective entities. In the example below, the entity "Barack Obama" appears as a hyperlink.

To view all entities recognized in the document content, click Show all document entities in the top right corner of the Document Detail screen. This shows all entities recognized in the text with hyperlinks to their entity description.

To return to the default view, you can click Show searched entities only and you can see again only the selected entities in the content of the document.

Entity Description

Entity Description shows the ontology class to which the selected entity belongs to, the main relations defined for it, and a list of related entities. You can view it from:

• Facets by clicking the red magnifying glass in front of each entity name in the columns.
• Entity Query Result by clicking an entity marked as hyperlink in blue in the Entity column.
• Document Detail by clicking an entity marked as a hyperlink in blue in the Body section.

Entity Description consists of two sections. The first section displays the preferred synonym, the definition of the concept, and a list of the main relations defined for the selected entity. The second section shows the entities to which the selected entity is related.

For example, if you click on the link “United States”, in the first section of the entity description, “United States” is defined as an entity of the type “Country”. It is marked as trusted which means that it was pre-populated in the knowledge base from a trusted source. Its main alias is “United States” but it also has another alias like: “U.S.”, "US", "U.S", etc. It has many types of relations with other entities some of which are:

• hasAdjective Americano , Americain , Americains , American , Americaines ...

On the right-hand corner of the window you can find the icons.
