OSF Tagger (scones)
The OSF Tagger (scones) Web service is used to perform subject concepts and named entities tagging on a target document. The tagger gets its scones name from the acronym subject concepts or named entities.
Developers communicate with the OSF Tagger Web service using the HTTP POST method.
This documentation page is used for the version 3.3 of this endpoint. Check at the top of this page to see the documentation pages for the other versions of this endpoint.
This Web service is intended to be used by users that wants to tag subjects concepts and named entities using the content of a target OSF Web Service instance.
Since the OSF tagger is re-using the ontologies & named entities defined on a specific OSF Web Service instance, tagging will be performed using this specific information. So, if a specific OSF Web Service instance is hosted, maintained and defined by a Health related organization, than their OSF tagger web service should be better at tagging Health related documents.
So, not all OSF tagger instances are equal, and some are expected to be better at tagging specific articles than other, depending on the domain defined on a specific node.
Web Service Endpoint Information
This section describes all the permissions you need in the WSF (Web Service Framework) to send a query to this Web service endpoint, and it describes how to access it.
To access this Web service endpoint you need the proper CRUD (Create, Read, Update and Delete) permissions on a specific graph (dataset) of the WSF. Without the proper permissions on this graph you won't be able to send any queries to the endpoint.
- Create: False
- Read: True
- Update: False
- Delete: False
Here is the information needed to communicate with this Web service's endpoint. Descriptions of the parameters are included below.
Note: if a parameter has a default value, the requester can omit it and the default value will be used. Also, some baseline Web services may not offer other values than the default.
Possible "Accept:" HTTP header field value:
- http://[...]/ws/scones/ ?document=&type=&stemming=&application=&interface=&version=
URI dynamic parameters description:
Note: All parameters have to be URL-encoded
- document. Document content to process; or URL of a document accessible on the web to extract/process
- The document types accessible at that URL can be either:
- a plain text document
- a HTML document
- a PDF document
- a MS Word document
- a Email document
- a RTF document
- a SGML document
- a XML document
- The document types accessible at that URL can be either:
- type. The type of tagger the requester want to use
- "plain" (default) - specify that you want to tag all kind of words from the input document
- "noun" - specify that you want to only consider noun words when tagging the input document
- stemming. Use the stemmer when performing the tagging
- "false" (default) - do not use the stemmer
- "true" - use the stemmer
- application.(default: defaultApplication). Application to use to tag the content of the input document. If other applications are available, these should be listed somewhere on the website of the agent that host the service.
- interface. Source interface used for this web service query. The interface is a different way to process a query (different algorithms, different data management system, etc. The default interface is 'default'
- version. (default: 3.0) Version of the interface to query
Available Sources Interfaces
A source interface is a way to process a web service query. Different sources interfaces can be implemented for the same OSF Web Service endpoint. Each interface will process the query differently, but all the queries to the web service endpoint will be the same, at the exception of the
interface parameter. Each interface shares the same API (the one defined by the web service endpoint), but their processing may differ (like using different algorithms, using different data management systems, etc.)
This is a list of the core interfaces for this endpoint. Organizations that hosts a OSF Web Service network could create their own interface and make it available to the users. However such private source interface won't be part of this list, but should be publicized by the organization.
|Source Interface Name||Description|
||Default source interface for this OSF Web Service endpoint. This interface implements the default behavior of this OSF Web Service endpoint.|
