A positioning server may acquire at least one candidate AP set from an initial AP set, wherein each of the at least one candidate AP set includes a preset number of APs enclosing a terminal which is to be positioned. The positioning server may select a target AP set from the at least one candidate AP set, wherein a distance from each of the APs included in the target AP set to the terminal is less than a preset threshold. The positioning server may determine the preset number of APs included in the target AP set as positioning APs for positioning the terminal.

An emotion function chain may be generated from an email thread and displayed to a user in one or more windows on a computer display of a computer system. An email content analyzer may extract emotion indicators from the body of an email within the email thread. Using the emotion indicators, an attitude factor for an email may be determined. The attitude factors determined from each email within the email thread may be pictorially depicted in the emotion function chain. In response to a user interaction with a pictorial depiction of an attitude factor within the emotion function chain, a second window may generated to display the body of the email used to calculate the attitude factor interacted with.
