A goal - oriented Web browser 4

p0220 Many users are familiar with the interesting but limited functionality of data detector interfaces like Microsoft’s Smart Tags and Google’s AutoLink. In this chapter we significantly expand the breadth and functionality of this type of user interface through the use of large-scale knowledge bases of semantic information. The result is a Web browser that is able to generate personalized semantic hypertext, providing a goal-oriented browsing experience. p0225 We present (1) Creo, a programming-by-example system for the Web that allows users to create a general purpose procedure with a single example; and (2) Miro, a data detector that matches the content of a page to high-level user goals. p0230 An evaluation with 34 subjects found that they were more efficient using our system, and that the subjects would use features like these if they were integrated into their Web browser. s0010 INTRODUCTION p0235 In this chapter we describe a programming-by-example system for the Web named Creo, and a data detector named Miro. Working together, Creo and Miro provide the user with a goal-oriented Web browsing experience. We describe an evaluation of our software based on data from 34 users, and evaluations of our software’s user interface during an iterative design process. p0240 Finally, we conclude with a discussion of how large-scale knowledge bases of semantic information can be leveraged to improve human–computer interaction.
