    • Techniques for returning estimated value of search keywords of an entire account include, for the entire account, obtaining one or more selected search keywords and their respective forecast periods and parameter settings. An estimated value of a respective search keyword in the respective forecast period is forecasted. Based on stored historical data and parameter settings of the respective search keyword, the estimated value of the respective search keyword is modified to obtain a modified estimated value. The modified estimated value of each search keyword is added up to generate an estimated value of the entire account. The estimated value of the entire account is returned to a client terminal from which the entire account is logged in. The present disclosure modifies the respective search keyword's estimated value so that the estimated value of the entire account satisfies the expected value of the client.
    • 返回整个帐户的搜索关键字的估计值的技术包括对于整个帐户获得一个或多个所选择的搜索关键字及其各自的预测期间和参数设置。 预测各个预测期间内的搜索关键词的估计值。 基于相应搜索关键字的存储历史数据和参数设置,修改相应搜索关键字的估计值以获得修改的估计值。 每个搜索关键字的修改后的估计值相加,以生成整个帐户的估计值。 整个帐户的估计值被返回到整个帐户登录的客户终端。本公开修改了相应的搜索关键字的估计值,使得整个帐户的估计值满足客户端的期望值。

    • A method and an apparatus for identifying synonym and utilizing such synonym to conduct search is disclosed. The disclosed method includes: obtaining arbitrary two words to be identified; determining whether a shortest edit distance between the two words less than or equal to an edit distance threshold; determining whether the two words to be identified exist in a preset knowledge database, and if an answer is yes then searching a smallest granularity type with highest weight value for each word in the knowledge database; and if the two word have the same smallest granularity type with highest weight value, then determining such two words are synonyms, or non-synonym otherwise. The disclosed techniques greatly improve accuracy of synonym identification and guarantee effect of synonym identification.
    • 公开了一种用于识别同义词并利用这种同义词进行搜索的方法和装置。 所公开的方法包括:获得待识别的任意两个字; 确定两个单词之间的最短编辑距离是否小于或等于编辑距离阈值; 确定要确定的两个词是否存在于预设知识数据库中,如果答案为是,则搜索知识数据库中每个单词的最大权重值的最小粒度类型; 并且如果这两个字具有最高重量值的相同最小粒度类型,则确定这两个字是同义词,否则确定为非同义词。 所公开的技术大大提高同义词识别的准确性并保证同义词识别的效果。

    • A combined CDM/TDM (code division multiplexing/time division multiplexing) transmitter and method are provided which employ fractional slot assignment by assigning fractional CDM channel gains to multiple slots for at least one packet with a goal that a sum of fractional CDM gains assigned each packet over a scheduling period meet a required threshold. In some embodiments, the transmitter is adapted to determine which users to transmit during a given slot, and to determine fractional CDM channel gains using an optimization of fractional CDM channel gain and user assignment which maximizes a number of users each of which is assigned a respective group of one or more slots with fractional CDM channel gains which sum to the required threshold for the user.

    • A method and apparatus for reducing the peak to average power ratio of an OFDM signal. The method involves operating on the signal only after it is converted to the time domain where the signal is compared to a power threshold and any signal above the power threshold is considered undesirable. A reduced signal is produced by reducing the magnitude to the power threshold whenever it exceeds that threshold. The delta between the original signal and reduced signal is the clipped signal. The clipped signal is multiplied by a g-function, and then subtracted from the original signal to produce a first iteration of a peak-reduced signal. The process can then be repeated using the first peak-reduced signal in place of the original signal to produce the second iteration of a peak-reduced signal. This process can be repeated each time bringing the peaks closer to the power threshold. The g-function can be defined either to allow for per-symbol cyclic signal processing or non-cyclic processing that is symbol time independent.
    • 一种降低OFDM信号的峰均功率比的方法和装置。 该方法仅在将信号转换为信号与功率阈值进行比较的时域之后对信号进行操作,并且认为任何高于功率阈值的信号都是不合需要的。 通过在超过该阈值时将功率阈值的幅度减小来产生降低的信号。 原始信号和减小信号之间的差值是限幅信号。 剪切信号乘以g函数,然后从原始信号中减去,以产生峰值降低信号的第一次迭代。 然后可以使用第一峰值降低信号代替原始信号来重复该过程,以产生峰值降低信号的第二次迭代。 每次使峰值更接近功率阈值时,可以重复该过程。 g函数可以被定义为允许符号时间无关的每符号循环信号处理或非循环处理。
