摘要： Systems and methods to process and correct spelling errors for non-Roman based words such as in Chinese, Japanese, and Korean languages using a rule-based classifier and a hidden Markov model are disclosed. The method generally includes converting an input entry in a first language such as Chinese to at least one intermediate entry in an intermediate representation, such as pinyin, different from the first language, converting the intermediate entry to at least one possible alternative spelling or form of the input in the first language, and determining that the input entry is either a correct or questionable input entry when a match between the input entry and all possible alternative spellings to the input entry is or is not located, respectively. The questionable input entry may be classified using, for example, a transformation rule based classifier based on transformation rules generated by a transformation rules generator.

摘要： Systems and methods to process and translate pinyin to Chinese characters and words are disclosed. A chinese language model is trained by extracting unknown character strings from Chinese inputs, e.g., documents and/or user inputs/queries, determining valid words from the unknown character strings, and generating a transition matrix based on the Chinese inputs for predicting a word string given the context. A method for translating a pinyin input generally includes generating a set of Chinese character strings from the pinyin input using a Chinese dictionary including words derived from the Chinese inputs and a language model trained based on the Chinese inputs, each character string having a weight indicating the likelihood that the character string corresponds to the pinyin input. Ambiguous user input may be classified as non-pinyin or pinyin by identifying an ambiguous pinyin/non-pinyin ASCII word in the user input and analyzing the context to classify the user input.
摘要翻译：披露了将拼音处理和翻译成汉字和词语的系统和方法。通过从中文输入（例如文档和/或用户输入/查询）中提取未知字符串，从未知字符串中确定有效字，并基于中文输入生成用于预测字串的转换矩阵来训练中文模型给定上下文。用于翻译拼音输入的方法通常包括使用中文字典从拼音输入生成一组汉字字符串，包括从中文输入得到的词和基于中文输入训练的语言模型，每个字符串具有指示字符串对应于拼音输入的可能性。通过识别用户输入中的歧义拼音/非拼音ASCII字词并分析上下文以对用户输入进行分类，可能将歧义用户输入分类为非拼音或拼音。

摘要： A system receives yellow page data, map provider data, and document data in response to a local search query, and geocodes the data to assign a geographic idetifier and to match at least one address associated with the local search query. The system also index the geocoded data to determine business information and location information associated with thee local search query. The system further provides local search results and a map based on the indexed data (Figure 1).
摘要翻译：系统响应于本地搜索查询接收黄页数据，地图提供者数据和文档数据，并且对数据进行地理编码以分配地理标识符并且匹配至少一个与本地搜索查询相关联的地址。系统还对地理编码数据进行索引，以确定与本地搜索查询相关联的业务信息和位置信息。该系统还提供本地搜索结果和基于索引数据的地图（图1）。
