- The design principles are offer informative feedback, reduce working memory, provide alternative interface for novice and expert users, information access interfaces.
- Precision and recall measures have been widely used for comparing the ranking results of non-interactive systems, but are less appropriate for assessing interactive systems. The standard evaluations emphasize high recall levels.
- The user interface should also support methods for monitoring the status of the current strategy in relation to the user's current task and high-level goals.
- Studies show that users tend to start out with very short queries, inspect the results, and then modify those queris in an incremental feedback cycle.
The Design of Search User Interfaces
- The most understandable and transparent way to order search results is according to how recently they appeared.
- Another important issue in the tradeoff between system cleverness and user control lies with query transformations.
- Keyboard shortcuts can save time and effort when the user is typing, as the shortcuts remove the need to move hands away from the keyboard to the mouse. But there is a barrier to using shortcuts, as they require memorization.
Information Visualization For Text Analysis
- One of the most common strategies used in text mining is to identify important entities within the text and attempt to show connections among those entities.
- Standard data graphics can be an effective tool for understanding frequencies of usage of terms within documents.
