Unstructured Information Management Architecture SDK

Unstructured information management UIM applications are software systems that analyze unstructured information text, audio, video, images, and so on to discover, organize, and deliver relevant knowledge to the user. In analyzing unstructured information, UIM applications make use of a variety of analysis technologies, including statistical and rule-based Natural Language Processing NLPInformation Retrieval IRmachine learning, and ontologies.

IBM’s Unstructured Information Management Architecture UIMA is an architectural and software framework that supports creation, discovery, composition, and deployment of a broad range of analysis capabilities and the tutkrial of them to structured information services, such as databases or search engines.

The UIMA framework provides a run-time environment in which developers can plug in and run their UIMA component implementations, along with other independently-developed components, and with which they can build and deploy UIM applications.

The framework is not specific to any IDE or platform. It also supports the developer with an Eclipse -based development environment that includes a set of tools and utilities for using UIMA. One large, but not the only, application area of text analysis is improving text search. By detecting important terms and topics within documents, semantic search engines provide the capability to search for concepts and relationships instead of keywords. Another large application area is information extraction.

The text-analysis functions of IBM DB2 Warehouse Edition focus on information extraction that creates structured data out of unstructured data. DB2 Warehouse Edition allows UIMA annotators to be plugged into a Mining flow, enabling the extraction of information that can then be analyzed together with structured information by using business intelligence tools.

At the heart of AEs are the analysis algorithms that do all the work to analyze documents and record analysis results for example, detecting person names. These algorithms are packaged within components that are called Annotators. AEs are the stackable containers for annotators and other analysis engines.

The CAS is an tutorrial container that manages and stores typed objects having properties and values. Object types may be related to each other in a single-inheritance hierarchy. Annotators are given a CAS having the subject of analysis the documentin addition to any previously created objects from annotators earlier in the pipelineand they add their own objects to the CAS.

Group: Apache UIMA

The CAS serves as a common data object, shared among the annotators that are assembled for an application. Many UIM applications analyze entire collections of documents. This part of the architecture allows specification of a “source-to-sink” flow from a collection reader though a set of analysis engines and then to a set of CAS Consumers.

The collection reader’s job is to connect to and iterate through a source collection, acquiring documents and initializing CASes for analysis.

After the analysis engines have added their information to the CAS, CAS consumers do the final CAS processing, for example, sending the CAS contents to a search engine or extracting elements of interest and populating a relational database. The purpose of this working group is the creation of standards to ensure interoperability between different UIM applications and thus create an open ecosystem of unstructured analysis platforms and applications.

It will be some time before the first release will be available from Apache. It is a world-wide effort, with significant participation from the following IBM sites:. Its versions may evolve more rapidly, and are not tied to specific Uina or DB2 Warehouse releases.

The SDK is supported on a “best can do” basis, by way of the alphaWorks forum. It is intended for users who want to develop and deploy semantic search solutions with IBM OmniFind Enterprise Edition or solutions that take advantage of OmniFind’s capabilities for enterprise-scale document crawling and extraction.

How does it work? What’s new in UIMA release 1. XMI support has been added.

There are two new chapters in the user’s guide describing this support. As a part of this change, additional type system feature description information for types which are arrays or lists can now be specified, including the type of the elements of these collections.

A new utility to merge two or more PEAR files has been added, and is described in the user’s guide. Please see the release notes for details on other enhancements and bug fixes.
