Description

Summary Description

Interacts with disparate morphology services and text repositories to provide the ability to process, retrieve and store morphological analyses for specified texts.

Full Description

The Morphological Analysis Service responds to requests for morphological analysis of texts, submits them to the appropriate morphology service for processing and returns the results in XML adhering to a standard morphology schema.  The Service supports retrieval of texts for analysis from remote repositories as well as user-supplied chunks of text.  Where retrieval from repository is requested, CMIS objectIDs and CTS URNs are supported as document identifiers.

Component

Responsibility

Client

Initiates Request, Supplies user auth info to person/profiles/services; Supplies personId and documentId to MAST service; retrieves cached results from result set service

Person/Profiles/Groups

Authenticates with IDP; supplies opaque personId to BSP services; validates personId;

MAST service

requests guid from result set cache; identifies repository for document; retrieves documents from remote repository; tokenizes documents into words; issues request(s) to remote morphology service; compiles and stores result set in result set cache service

Result Set Cache Service

creates guid for result set; notifies notification service when result set storage is complete

Notification Service

notifies client of result set availability

Remote Repository

supplies documents

Remote Morphology Service

analyzes words
