2. It reminds the user of features that would be desirable to include or exclude when those features might not otherwise have occurred to the user.

3. It reminds the user of his/her intention by presenting example instances.

4. It organizes the database information in a knowledge base to capture its conceptual structure.

Based on the paradigm of retrieval by reformulation, two early systems have been built to assist users in retrieving information from knowledge bases or databases: RABBIT (Tou 82, Williams 841 and ARGON [Patel-Schneider 84]; however, these systems are designed specifically for query-based retrieval. In particular, they do not support two classes of tasks:

1. knowledge base browsing, which is useful for constructing and maintaining the knowledge base that captures the conceptual structure of the database entities;

2. performing actions that utilize the retrieval results.

IntelliscopeTM, a recent commercial product developed at Intellicorp, employs the retrieval by reformulation paradigm and allows actions on retrieved results. However, it does not provide simple hooks for extension and is also restricted to data retrieval. To extend the paradigm of

BACKBORD extends the retrieval by reformulation paradigm in several ways. First, the application domain of the paradigm is extended beyond database retrieval into knowledge base browsing activities and users' actions on the retrieval results. Second, it provides various reminder facilities and a history mechanism to aid users in keeping track of their interactions with the system. Third, it suggests a general mechanism for the application builder to add domain-specific actions into the system in a way such that only the relevant data objects are
