METHOD AND APPARATUS OF SELECTING EXPANSION TERM PAIRS

摘要

A method of selecting expansion term pairs to solve a problem that only a relatively small number of expansion term pairs may be determined under a circumstance of not enough user activities according to an existing method of determining an expansion term pair is disclosed. The method includes: acquiring at least two query term pairs, each query term pair including at least one query term as a bid-word; determining query term pairs in which a respective co-occurrence number of each query term included in a specific period of time is less than a first number-of-time threshold from among the at least two query term pairs; and selecting query term pair(s) that satisf(ies) a configured expansion term pair necessary condition as expansion term pair(s) from among the determined query term pairs. The present disclosure further discloses an apparatus of selecting expansion term pairs.

1. A method implemented by one or more computing devices, the method comprising:
obtaining at least two query term pairs, each query term pair of the at least two query term pairs including at least one query term as a bid-word; determining that a respective number of times of co-occurrence of each query term included in at least one query term pair within a specific period of time is less than a first number-of-time threshold from among the at least two query term pairs; and selecting one or more query term pairs that satisfy a condition as one or more expansion term pairs from among the at least one query term pair.
