Literature search system-oriented search prompt word generation method

The invention discloses a literature search system-oriented search prompt word generation method. The method comprises the following steps: S1, inputting keywords by a user, returning literature search results by a literature search system, capturing user download behaviors in real time, and obtaining literature texts downloaded by the user; S2, connecting the literature texts downloaded by the user end to end according to a download sequence to form a long text, extracting relationships between the keywords of the long text, and constructing keyword networks as core semantics of the long text; S3, fusing the keyword networks of the long text into a prompt word network, and extracting and displaying prompt words in real time; S4, judging whether the user still has the download behaviors or not, and if so, skipping to the step S2, otherwise, skipping to the step S5; and S5, ending the prompt word generation. The method is added into a current literature search system, so that personalized search prompt words can be provided for users, the search time can be shortened, and user search experience can be improved.
