A method for determining at least one recommended search strategy in response to a user query received from a terminal device, comprising:

• receiving the user query from the terminal device via the data exchange port, the user query comprising at least one first segment;
• in response to the user query, obtaining a plurality of search strategies matching the user query, each of the plurality of search strategies comprising at least one second segment;
• obtaining a text similarity determination model, the text similarity determination model being adapted to incorporate an attention mechanism;
• for each of the plurality of search strategies, determining a similarity score between a first vector representing the user query and a second vector representing the search strategy, wherein the similarity score is determined by inputting the user query and the search strategy into the text similarity determination model, wherein at least one of the first vector or the second vector is associated with an attention weight of each corresponding segment in the corresponding vector, the attention weight being determined based on the attention mechanism;
• determining, among the plurality of search strategies, the at least one recommended search strategy based on the similarity scores;
• and
• transmitting the at least one recommended search strategy to the terminal device for display.

A non-transitory computer-readable storage medium embodying a computer program product, the computer program product comprising instructions configured to cause a computing device to:

• receive the user query from the terminal device via the data exchange port, the user query comprising at least one first segment;
• in response to the user query, obtain a plurality of search strategies matching the user query, each of the plurality of search strategies comprising at least one second segment;
• obtain a text similarity determination model, the text similarity determination model being adapted to incorporate an attention mechanism;
• for each of the plurality of search strategies, determine a similarity score between a first vector representing the user query and a second vector representing the search strategy, wherein the similarity score is determined by inputting the user query and the search strategy into the text similarity determination model, wherein at least one of the first vector or the second vector is associated with an attention weight of each corresponding segment in the corresponding vector, the attention weight being determined based on the attention mechanism;
• determine, among the plurality of search strategies, the at least one recommended search strategy based on the similarity scores;
• and
• transmit the at least one recommended search strategy to the terminal device for display.
