Abstract: A two-dimensional representation of a document is leveraged to extract a hierarchical structure that facilitates recognition of the document. The visual structure is grammatically parsed utilizing two-dimensional adaptations of statistical parsing algorithms. This allows recognition of layout structures (e.g., columns, authors, titles, footnotes, etc.) and the like such that structural components of the document can be accurately interpreted. Additional techniques can also be employed to facilitate document layout recognition. For example, grammatical parsing techniques that utilize machine learning, parse scoring based on image representations, boosting techniques, and/or "fast features" and the like can be employed to facilitate in document recognition.

Abstract: Techniques for efficiently and accurately organizing freeform handwriting into lines. A global cost function is employed to find the simplest partitioning of electronic ink strokes into line groups that also maximize the "goodness" of the resulting lines and the consistency of their configuration. The "goodness" of a line may be based upon its linear regression error and the horizontal and vertical compactness of the strokes making up the line. The line consistency configuration for a grouping of strokes is measured by the angle difference between neighboring groups. The global cost function also takes into account the complexity of the stroke partitioning, measured by the number of lines into which the strokes are grouped.

Abstract translation: 有效和准确地将自由笔迹组织成线条的技巧。 采用全局成本函数来找到电子墨水笔划最简单的划分成线组，从而最大限度地提高生成线的“良好性”和其配置的一致性。 线条的“好”可以基于其线性回归误差以及构成线条的笔划的水平和垂直紧密度。 一组笔划的线一致性配置通过相邻组之间的角度差来测量。 全局成本函数还考虑了划分划分的复杂性，划分的划分由笔划分组的行数衡量。

Abstract: A system and method that facilitates and effectuates in situ search for active note taking. The system and method includes receiving gestures from a stylus and a tablet associated with the system. Upon recognizing the gesture as belonging to a set of known and recognized gestures, the system creates an embeddable object, initiates a search with terms indicated by the gesture, associates the search results with the created object and inserts the object in close proximity with the terms that instigated the search.
