The embodiment of the invention provides a method for obtaining interest point information. The method comprises the steps that recognition is carried out on test information in documents in a language database by utilizing an interest point word list to obtain a first interest point sequence, wherein the first interest point sequence contains at least two candidate interest points which are contained in the documents; number adjustment is carried out on the at least two candidate interest points and/or sequence adjustment is carried out on the at least two candidate interest points to obtain a second interest point sequence, and the second interest point sequence serves as the interest point sequence matched with the documents. The embodiment of the invention further provides a device for obtaining the interest point information and a method and a device for pushing the interest point information. According to the technical scheme of the embodiment, obtaining efficiency of interest point information can be improved.
