After you build your custom analysis by using the Unstructured
Information Management Architecture (UIMA), you can integrate the
analysis logic by using the IBM® Content
Analytics with Enterprise Search administration
console.
UIMA is an open
platform that identifies components for each conceptually distinct
analysis function, and it ensures that these components can be easily
reused and combined.
Advanced linguistic analysis can include a combination of many
different analysis tasks. The analysis begins with language detection
and segmentation, and continues with part-of-speech recognition, followed
by deep grammatical parsing. The last tasks include identifying, for
example, the relation between certain chemical substances and the
appearance of particular symptoms. Each step in the analysis process
depends on the results of the previous step.
The analysis logic for each step is contained in an annotator.
Annotators combine to form a processing chain that iterates over each
document in the collection to discover new information and store this
information for downstream processing.
The annotators that are responsible for discovering and representing
analysis content in text documents are contained in an analysis
engine, a central concept in UIMA. An analysis engine
might contain a single annotator or it might be a composite of many
engines, each in turn containing annotators.
UIMA only provides
the basic building blocks for you to create, test, and deploy your
own analysis engines. It does not provide you with any linguistic
analysis functionality in the form of pre-configured analysis engines
that you can deploy in your UIMA environment.
However, the linguistic processing that is applied is available as
a set of annotators that you can work with in UIMA.
To work with UIMA,
you can install the Apache UIMA Software
Development Kit (SDK), Version 2.3. The SDK is available on the Apache UIMA site. The UIMA SDK includes a Java implementation of the UIMA framework for the implementation,
description, composition and deployment of UIMA components.
The UIMA SDK
also provides a set of tools and utilities for working with UIMA in an Eclipse-based
development environment (Eclipse plug-ins). For information about
Eclipse and to download the software, see the Eclipse site. For instructions
on how to install the UIMA SDK
in the Eclipse Interactive Development Environment, see the UIMA documentation.
As an alternative to manually developing
annotators with the UIMA SDK,
you can use Content Analytics Studio to
easily develop and deploy custom text analytics for IBM Content
Analytics with Enterprise Search applications. Content Analytics Studio is a separately installable
component of IBM Content
Analytics with Enterprise Search.
