UIMA (Unstructured Information Management applications) 是一个软件系统，用来分析大量的非结构化信息从而发掘中对最终用户有用的知识点，一个最典型的 UIM 应用就是从文本文件中提取有用信息，例如人员、地址和组织等相关信息。
下面是 UIMA 的结构图：
Apache UIMA Java SDK 2.4.1 发布了，改进内容包括：
* Documentation of binary serialization. * New kinds of compressed binary serialization that compress the data significantly and one form that supports unequal source/target type systems * A new facility called External Parameter Overrides for specifying parameter settings for annotators that uses properties files and is independent of the annotator hierarchy * CasCopier enhancements to allow copying one view to a different view. * Additional options to restrict JCasGen operation to generating just those types that are defined in a project, excluding other types that are imported from other projects * A new Maven plugin that runs JCasGen (see tools documentation for how to configure and use this) * A new ability to preserve white space (indentation) when parsing XML descriptors; this is now used in the Component Descriptor Editor (CDE), to preserve indentation when editing an existing descriptor. * Performance and space improvements, including some bulk methods for efficiently removing Feature Structures from Indexes
