在任何类型的分析中，理解数据体是一种常见的活动。语义生成是搜索表示并在该表示中编码数据以回答特定于任务的问题的过程。不同的语义生成过程需要不同的认知资源和外部资源。选择和更改表示以减少信息处理任务中的操作成本。这些表征转换的力量通常被低估了，就像理解和信息检索之间的关系一样。我们分析了语义构建任务，并建立了语义构建的成本结构模型。我们讨论了用户界面、表示工具和信息检索系统集成设计的含义。
Making sense of a body of data is a common activity in any kind of analysis. Sensemaking is the process of searching for a representation and encoding data in that representation to answer task-specific questions. Different operations during sensemaking require different cognitive and external resources. Representations are chosen and changed to reduce the cost of operations in an information processing task. The power of these representational shifts is generally under-appreciated as is the relation between sensemaking and information retrieval. We analyze sensemaking tasks and develop a model of the cost structure of sensemaking. We discuss implications for the integrated design of user interfaces, representational tools, and information retrieval systems.
