Method for identifying questions with same semantics and electronic device

An apparatus, comprising:

• one or more processors;
• and
• a memory coupled to the one or more processors, wherein the memory is configured to store code, wherein when the code is executed by the one or more processors, the apparatus is configured to:
• create, based on at least two user logs, a user behavior graph, wherein each user log comprises at least one user identifier, at least one question, and at least one answer corresponding to each question, wherein in the user behavior graph, an ith user node corresponds to a user identifier in an ith user log, wherein the ith user node is separately connected to at least one question node, wherein the at least one question node corresponds to at least one question in the ith user log, wherein a jth question node in the at least one question node is separately connected to at least one answer node, wherein the at least one answer node corresponds to at least one answer that is in the ith user log and that corresponds to the jth question node, wherein i and j are positive integers, wherein the ith user log is any one of the at least two user logs, and wherein the jth question node is any one of the at least one question node;
• obtain, based on the user behavior graph and a seed question, a first associated question node set, wherein the first associated question node set comprises a question node corresponding to the seed question and M associated question nodes, wherein M is a positive integer;
• and wherein the seed question is a question in the at least two user logs;
• calculate, based on the first associated question node set, association scores of questions corresponding to all question nodes in the user behavior graph;
• use a question corresponding to each associated question node in the first associated question node set as a new seed node to obtain M second associated question node sets;
• update, based on the M second associated question node sets, the association scores to produce updated association scores;
• and
• obtain, based on the updated association scores, K questions with top K association scores,
• wherein K is an integer greater than 1.

A computer program product comprising computer-executable instructions stored on a non-transitory computer-readable medium that, when executed by one or more processors, cause an apparatus to:

• create, based on at least two user logs, a user behavior graph, wherein each user log comprises at least one user identifier, at least one question, and at least one answer corresponding to each question, wherein in the user behavior graph, an ith user node corresponds to a user identifier in an ith fuser log, wherein the ith user node is separately connected to at least one question node, wherein the at least one question node corresponds to at least one question in the ith user log, wherein a jth question node in the at least one question node is separately connected to at least one answer node, wherein the at least one answer node corresponds to at least one answer that is in the ith user log and that corresponds to the jth question node, wherein i and j are positive integers, wherein the ith user log is any one of the at least two user logs, and wherein the jth question node is any one of the at least one question node;
• obtain, based on the user behavior graph and a seed question, a first associated question node set, wherein the first associated question node set comprises a question node corresponding to the seed question and M associated question nodes, wherein M is a positive integer;
• and wherein the seed question is a question in the at least two user logs;
• calculate, based on the first associated question node set, association scores of questions corresponding to all question nodes in the user behavior graph;
• use a question corresponding to each associated question node in the first associated question node set as a new seed node to obtain M second associated question node sets;
• update, based on the M second associated question node sets, the association scores to produce updated association scores;
• and
• obtain, based on the updated association scores, K questions with top K association scores,
• wherein K is an integer greater than 1.
