摘要： An author-oriented document summarizer for a word processor is described. The document summarizer performs a statistical analysis to generate a list of ranked sentences for consideration in the summary. The summarizer counts how frequently content words appear in a document and produces a table correlating the content words with their corresponding frequency counts. Phrase compression techniques are used to produce more accurate counts of repeatedly used phrases. A sentence score for each sentence is derived by summing the frequency counts of the content words in a sentence and dividing that tally by the number of the content words in the sentence. The sentences are then ranked in order of their sentence scores. Concurrent with the statistical analysis, during the same pass through the document the summarizer performs a cue-phrase analysis to weed out sentences with words or phrases that have been pre-identified as potential problem phrases. The cue-phrase analysis compares sentence phrases with a pre-compiled list of words and phrases and sets conditions on whether the sentences containing them can be used in the summary. Following the cue-phrase analysis, the summarizer creates a summary containing the higher ranked sentences. The summary may also include a conditioned sentence if the conditions established for inclusion of the sentence have been satisfied. The summarizer then inserts the sentence at the beginning of the document before the start of the text.

摘要： A method and system for enabling a visually impaired user to use a touch-sensitive device. The present invention provides an interface for the visually impaired (IVI) system which enables a visually impaired user to use a touch-sensitive screen. The IVI system provides an explore mode in which a visually impaired user may determine which objects are on the touch-sensitive screen by dragging a finger over the touch-sensitive screen. In particular, the IVI system announces objects as a user touches them. For example, the IVI system announces text as it is touched and announces controls, such as buttons, as they are touched. In addition, the IVI system enables a user to execute controls. A user may execute a control, such as a button, by dragging a finger onto the control, and then, without dragging the finger off of the control, lifting the finger off of the touch-sensitive screen. The IVI system further enables a user to scroll through lists on a touch-sensitive screen. In particular, the IVI system enables a user to use a scroll thumb to scroll through a list. When a user drags a finger over the scroll thumb, and then, without dragging the finger off of the scroll thumb, lifts the finger off of the touch-sensitive screen, the IVI system enters scroll mode. In the scroll mode, a user may drag a finger anywhere on the touch-sensitive screen to scroll the list. While in scroll mode if a user again lifts their finger off of the touch-sensitive screen, the IVI system returns to explore mode.
摘要翻译：一种用于使视障用户能够使用触敏装置的方法和系统。本发明提供了一种用于视觉障碍（IVI）系统的界面，其使得视力受损的用户能够使用触敏屏幕。 IVI系统提供探索模式，其中视觉受损的用户可以通过在手触摸屏幕上拖动手指来确定哪些对象在触敏屏幕上。特别地，IVI系统在用户触摸它们时宣布对象。例如，IVI系统在被触摸时宣布文本，并且在被触摸时宣布诸如按钮之类的控件。此外，IVI系统使用户能够执行控制。用户可以通过将手指拖动到控制上来执行诸如按钮的控制，然后，不用将手指从控制器上拖出，从而将手指从触摸屏上提起。 IVI系统还允许用户在触敏屏幕上滚动列表。特别地，IVI系统使用户能够使用滚动缩略图滚动列表。当用户将手指拖动在滚动缩略图上时，然后将手指从滚动拇指上拉出时，将手指从触摸屏上提起，IVI系统进入滚动模式。在滚动模式中，用户可以在触敏屏幕上的任何地方拖动手指来滚动列表。在滚动模式下，如果用户再次将手指从触敏屏幕提起，则IVI系统将返回探索模式。
