摘要： Annotation engines are described for handling annotations added to a base document. The annotation engines automatically classify the type of annotations, including, but not limited to: a highlight annotation; a blob annotation (comprising an enclosing-type annotation); an underline annotation; a vertical bracket annotation; a call-out annotation; and a free-note annotation. The annotation engines accept input in the form of a hierarchical tree of document elements and generate an output in the form of a hierarchical tree of annotation elements. Among other uses, a reflow engine can use the output of the annotation engines to properly reposition annotations within a layout-modified base document.

摘要： Systems and methods for detecting annotation digital ink strokes and further associating annotation digital ink strokes with word digital ink strokes are presented. Ink strokes are captured on a writing surface and then classified as words or annotations. Annotations are then anchored to corresponding words. When words are relocated or edited on the writing surface, the anchored annotations are also relocated and may even be reshaped according to the changes in the anchored words.
摘要翻译：提出了用于检测注释数字墨水笔画并进一步将注释数字墨迹与字数字笔墨相关联的系统和方法。墨水笔画被捕获在书写表面上，然后分类为单词或注释。然后将注释锚定到相应的词。当在书写表面上重新定位或编辑单词时，锚定的注释也被重定位，甚至可以根据锚定单词的变化进行重新整形。

摘要： A mechanism for recognizing and inputting handwritten mathematical expressions into a computer by providing part of a multi-path framework is described. The part of the multi-path framework includes a subscript/superscript analysis and character determination component that is designed to identify subscript and superscript elements. A method for analyzing a handwritten mathematical expression includes receiving a symbols corresponding to handwritten mathematical expression input strokes, identifying subscript and/or superscript structures, and determining a character for each symbol of the set. A graph of vertexes and edges may be created based upon the set of symbols and the graph may be searched to determine optimized candidates.
摘要翻译：描述了通过提供一部分多路径框架来将手写数学表达式识别并输入计算机的机制。多路径框架的一部分包括下标/上标分析和字符确定组件，其被设计为识别下标和上标元素。一种用于分析手写数学表达式的方法包括接收对应于手写数学表达式输入笔画的符号，识别下标和/或上标结构，以及确定该组的每个符号的字符。可以基于符号集创建顶点和边缘的图形，并且可以搜索图形以确定优化的候选。
