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。
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
