This course demonstrates how modern search techniques integrate information retrieval methods with human-computer interaction studies so that data and information are represented in such a way that leads the user quickly and efficiently to relevant results.
In this course you will learn about techniques associated with human-computer information retrieval such as spelling suggestions and automatic query reformulation which puts control of selection and interpretation in the user’s hands.
Faceted search enables users to navigate information hierarchically, going from a category to its sub-categories, while ‘lookahead’ provides a general approach to exploration. For example, various web applications employ AJAX to automatically complete query terms and suggest popular searches.
