摘要： A natural input system is described for creating and editing complex structures in a typeset application. The natural input system receives a typeset representation of an object and converts the typeset format to generate a standard digital ink representation. The natural input system provides the generated ink representation to a natural input application where can be manipulated by the user with a rich set of correction and editing features provided by the natural input application. Once the end user is satisfied with the recognition result in the natural input application, the natural input system receives the recognition result based on the modified digital ink representation. The natural input system may convert the received recognition result to the typeset application format and provides the modified typeset representation to the typeset application for merging into the document the user is editing.

摘要： A processing device may recognize a number of input handwritten strokes, which may represent a mathematical expression, a chemical formula, or other two-dimensional structure. Rewriting rules of a grammar may be applied to the strokes to produce a number of possible recognition results. Each of the possible recognition results has a respective score based on a sum of rewriting rules applied to the strokes to produce respective ones of the possible recognition results. Input may be provided to identify misrecognized strokes and a correct terminal production, or symbol corresponding to the misrecognized strokes. Strokes may be misrecognized for many reasons, including parsing errors, over-grouping or under-grouping of matrices, and improper placement of a recognized terminal production, or symbol, with respect to a root structure. Correction hints may be leveraged for correcting types of errors mentioned above.
摘要翻译：处理装置可以识别可以表示数学表达式，化学式或其它二维结构的多个输入手写笔画。语法的重写规则可以应用于笔画以产生许多可能的识别结果。每个可能的识别结果具有基于施加到笔画的重写规则的总和的相应得分，以产生相应的可能的识别结果。可以提供输入以识别误识别的笔画和正确的终端制作或与错误识别的笔画相对应的符号。笔画可能由于许多原因而被误认识，包括解析错误，矩阵的分组过大或分组不足，以及对根结构的识别终端生产或符号的不正确放置。纠正提示可用于纠正上述错误类型。

摘要： In embodiments consistent with the subject matter of this disclosure, a user may input one or more strokes as digital ink to a processing device. The processing device may produce and present a recognition result, which may include a misrecognized portion. A user may indicate a desire to correct the misrecognized portion and may further select one or more strokes of the misrecognized portion. The processing device may then present the one or more recognition alternates corresponding to the selected one or more strokes of the misrecognized portion. In some embodiments, the processing device may permit a user to rewrite the selected one or more strokes of the misrecognized portion with newly entered digital ink. Features, such as, rewriting and correction of the input digital ink may be discoverable in some embodiments.

摘要： In embodiments consistent with the subject matter of this disclosure, a user may input strokes as digital ink to a processing device. The processing device may partition the input strokes into multiple regions of strokes. A first recognizer and a second recognizer may score grammar objects included in regions and represented by chart entries. The scores may be converted to a converted score, which may have at least a near standard normal distribution. The processing device may present a recognition result based on highest converted scores according to a recurrence formula. The processing device may receive a correction hint with respect to misrecognized strokes and may add a penalty score with respect to chart entries representing grammar objects breaking the correction hint. Incremental recognition may be performed when a pause is detected during inputting of strokes.
摘要翻译：在与本公开的主题相一致的实施例中，用户可以将笔画作为数字墨水输入到处理设备。处理装置可以将输入笔划划分成多个笔画区域。第一识别器和第二识别器可以对包括在区域中的语法对象进行评分并由图表条目表示。得分可以转换成转换得分，其可以具有至少近标准正态分布。处理装置可以根据递归公式提供基于最高转换分数的识别结果。处理设备可以接收关于错误识别的笔画的校正提示，并且可以相对于表示打破校正提示的语法对象的图表条目添加惩罚分数。当在笔画输入期间检测到暂停时，可以执行增量识别。
