Abstract: In reference to the optimal foraging principle of animal ecology, we analyze the behavior data of the readers in the digital resources platform, and establish the reader information foraging model based on reader behavior feedback data. Through optimization analysis model, the foraging strategy of the readers in the digital resource platform is forecasted to improve the reader’s information foraging ability, and eventually to achieve the purpose of subject service.

Key words: Information foraging, 　User behavior feedback, 　Log analysis, 　Subject service, 　Digital information service
