Introduction

Personal Information Management (PIM) aims to support users in the collection, storage and retrieval of their personal information. In such a framework the focus is mainly on how better to handle the information collected. Task Information Management (TIM) on the other hand adopts a more user- centric view and aims to support users in performing their tasks. Possible ways of achieving this are to automatically find data users need in order to perform a task, to automate the execution of tasks and the synthesis of new more abstract tasks by identifying tasks users carry out often. PIM and TIM can be seen as complimentary since an efficient organization of personal information can help in the discovery of data relevant to a task. To this end, it is necessary to adopt a holistic approach in the design and implementation of a Task Information Management System.
