Abstract: A system, method and computer-readable storage devices are for processing natural language commands, such as commands to a robotic arm, using a Tag & Parse approach to semantic parsing. The system first assigns semantic tags to each word in a sentence and then parses the tag sequence into a semantic tree. The system can use statistical approach for tagging, parsing, and reference resolution. Each stage can produce multiple hypotheses, which are re-ranked using spatial validation. Then the system selects a most likely hypothesis after spatial validation, and generates or outputs a command. In the case of a robotic arm, the command is output in Robot Control Language (RCL).

Abstract translation: 系统，方法和计算机可读存储设备用于使用标签＆解析方法来处理自然语言命令，诸如对机器人手臂的命令。 系统首先为句子中的每个单词分配语义标签，然后将标签序列解析为语义树。 系统可以使用统计方法进行标记，解析和参考解析。 每个阶段都可以产生多个假设，这些假设使用空间验证进行重新排序。 然后，系统在空间验证之后选择最可能的假设，并生成或输出命令。 在机器人臂的情况下，命令以机器人控制语言（RCL）输出。

Abstract: A system, method and computer-readable storage device which balance latency and accuracy of machine translations by segmenting the speech upon locating a conjunction. The system, upon receiving speech, will buffer speech until a conjunction is detected. Upon detecting a conjunction, the speech received until that point is segmented. The system then continues performing speech recognition on the segment, searching for the next conjunction, while simultaneously initiating translation of the segment. Upon translating the segment, the system converts the translation to a speech output, allowing a user to hear an audible translation of the speech originally heard.

Abstract translation: 一种系统，方法和计算机可读存储设备，其通过在定位连接时分割语音来平衡机器翻译的等待时间和精度。 该系统在接收到语音时将缓冲语音，直到检测到连接。 在检测到连接时，直到该点被接收为止。 然后，系统继续在段上执行语音识别，搜索下一个连接，同时启动段的翻译。 在翻译片段时，系统将翻译转换为语音输出，允许用户听到原始听到的语音的可听翻译。
