Personal Information Management: The Case for an Evolutionary Approach

This review paper argues that users of personal information management systems have three particularly pressing requirements, for which current systems do not fully cater: (i) To combat information overload, as the volume of information increases. (ii) To ease context switching, in particular, for users who face frequent interrupts in their work. (iii) To be supported in information integration, across a variety of applications. To meet these requirements, four broad technological approaches should be adopted in an incremental fashion: (i) The deployment of a unified file system to manage all information objects, including files, emails and webpage URLs. (ii) The use of tags to categorize information; implemented in a way which is backward-compatible with existing hierarchical file systems. (iii) The use of context to aid information retrieval; built upon existing file andtaggingsystemsratherthancreatingaparallelcontextmanagementsystem. (iv)Thedeployment of semantic technologies, coupled with the harvesting of all useful metadata.
