    • Techniques are provided which improve deal and advertisement targeting of users, and which may include facilitating user comparison of deals. Methods and systems may detect if an email contains deal information related to one or more deals. If an email contains deal information, the deal information may be extracted. When the email is opened by the user, a link may be displayed on top of (e.g., overlaid on) the email. The link may be configured such that clicking on the link transmits a search query comprising the extracted deal information to a deal service. The deal service may retrieve one or more additional deals which may be similar or related to the one or more deals received in the email. The additional deals may be selected by the deal service based at least in part on the extracted deal information.

    • A method, apparatus, and article of manufacture employing lexicon reduction using key characters and a neural network, for recognizing a line of cursive text. Unambiguous parts of a cursive image, referred to as “key characters,” are identified. If the level of confidence that a segment of a line of cursive text is a particular character is higher than a threshold, and is also sufficiently higher than the level of confidence of neighboring segments, then the character is designated as a key character candidate. Key character candidates are then screened using geometric information. The key character candidates that pass the screening are designated key characters. Two-stages of lexicon reduction are employed. The first stage of lexicon reduction uses a neural network to estimate a lower bound and an upper bound of the number of characters in a line of cursive text. Lexicon entries having a total number of characters outside of the bounds are eliminated. For the second stage of lexicon reduction, the lexicon is fitter reduced by comparing character strings using the key characters, with lexicon entries. For each of the key characters in the character strings, it is determined whether there is a mismatch between the key character and characters in a corresponding search range in the lexicon entry. If the number of mismatches for all of the key characters in a search string is greater than (1+(the number of key characters in the search string/4)), then the lexicon entry is eliminated. Accordingly, the invention advantageously accomplishes lexicon reduction, thereby decreasing the time required to recognize a line of cursive text, without reducing accuracy.
    • 一种使用关键字符和神经网络来进行词典缩减的方法,装置和制品,用于识别草书文本。 识别草书图像的明确部分,称为“关键字符”。 如果一行草图文本的一段是特定字符的置信度高于阈值,并且也足够高于相邻段的置信度,则该字符被指定为关键字符候选。 然后使用几何信息对关键字候选进行筛选。 通过筛选的关键角色候选人被指定为关键角色。 采用两个阶段的词典缩小。 词典缩减的第一阶段使用神经网络来估计草图文本行中的字符数的下限和上限。 消除了界限外的字符总数的词典条目。 对于词典缩减的第二阶段,通过使用关键字符与词典条目比较字符串来缩小词典。 对于字符串中的每个关键字符,确定在词典条目中的相应搜索范围中的关键字符和字符之间是否存在不匹配。 如果搜索字符串中所有关键字符的匹配数量大于(1+(搜索字符串/ 4中的关键字符数)),则排除词典条目。 因此,本发明有利地实现词典缩减,从而减少了识别草稿文本行所需的时间,而不降低精确度。

    • A multi-stage multi-network character recognition system decomposes the estimation of a posteriori probabilities into coarse-to-fine stages. Classification is then based on the estimated a posteriori probabilities. This classification process is especially suitable for the tasks that involve a large number of categories. The multi-network system is implemented in two stages: a soft pre-classifier and a bank of multiple specialized networks. The pre-classifier performs coarse evaluation of the input character, developing different probabilities that the input character falls into different predefined character groups. The bank of specialized networks, each corresponding to a single group of characters, performs fine evaluation of the input character, where each develops different probabilities that the input character represents each character in that specialized network's respective predefined character group. A network selector is employed to increase the system's efficiency by selectively invoking certain specialized networks selected, using a combination of prior external information and outputs of the pre-classifier. Relative to known single network or one-stage multiple network recognition systems, the invention provides improved recognition, accuracy, confidence measure, speed, and flexibility.
    • 多级多网络字符识别系统将后验概率的估计分解为粗略到精细阶段。 然后根据估计的后验概率分类。 这种分类过程特别适用于涉及大量类别的任务。 多网络系统分为两个阶段:软预分类器和多个专用网络组。 预分类器对输入字符进行粗略评估,发展输入字符落入不同预定义字符组的不同概率。 专用网络的每一行对应于单个字符组,对输入字符进行精细评估,其中每个字符都产生不同的概率,即输入字符表示专用网络各自的预定义字符组中的每个字符。 采用网络选择器来通过使用先前的外部信息和预分类器的输出的组合选择性地调用所选择的某些专用网络来提高系统的效率。 相对于已知的单网络或一级多网络识别系统,本发明提供了改进的识别,准确性,可信度测量,速度和灵活性。
