Abstract: A method involves identifying account data of an entity for a present time period, where the account data includes more than one first data value, creating a comparison group for the entity. The comparison group includes more than one second data value, the account data of the entity includes the second data values, and the second data values originate from a prior time period. The method further involves selecting, from the first data values, a subset of the first data values, selecting, from the second data values, a subset of the second data values, identifying, by accessing a library including anomaly detection methods, an anomalous value within the subset of the first data values by comparing the subset of the first data values with the subset of the second data values, selecting an action in response to identifying the anomalous value within the subset of first data values, and initiating the action.

Abstract: An advertisement generation system presents a time-dependent advertisement to a user based upon to a search term of a search query during a period of time via a communication network The system includes a search engine coupled to a web server for receiving the search query and for presenting a search results page. The search results page is accompanied with an immediate advertisement. In one embodiment, the system includes an advertisement repository to store data representing a plurality of advertisements and includes the immediate advertisement and the time-dependent advertisement. Also, the system includes a user profiler configured to communicate a plurality of search characteristics and includes a data structure to store the search characteristics.
