Semantic parsing method and server

A method implemented by a second server, wherein the method comprises:

• receiving, from a first server, a first service request, comprising first indication information of a first intention and a first entity of a first slot, wherein the first entity is based on a modification from a pronoun to a second entity of a second slot if when the first entity extracted from a first user sentence is the pronoun, wherein the second slot is associated with the first slot, wherein the first slot is associated with the first intention, wherein the first intention is associated with a first skill, wherein one or more intentions are associated with the first skill, wherein the second server is an application server corresponding to the first skill, wherein the first skill and the first intention are based on the first user sentence and match a first service requirement expressed in the first user sentence, wherein the second slot is associated with a second intention, wherein the second intention is associated with a second skill, wherein the second skill is associated with the first skill, wherein the second skill and the second intention are based on a second user sentence and match a second service requirement expressed in the second user sentence, and wherein the second user sentence is from the electronic device before the first user sentence;
• determining a first service result based on the first indication information and the first entity;
• and
• sending, in response to the first service request, the first service result to the first server.

A computer program product comprising computer-executable instructions that are stored on a non-transitory computer readable medium and that, when executed by a processor, cause a first server to:

• receive a second user sentence;
• receive a first user sentence after receiving the second user sentence;
• determine, based on the first user sentence, a first skill and a first intention that is associated with the first skill, wherein the first skill and the first intention match a service requirement expressed in the first user sentence, and wherein one or more intentions are associated with the first skill;
• extract, from the first user sentence, a first entity of a first slot, wherein the first slot is associated with the first intention
• extract, from the second user sentence, a second entity of a second slot, wherein the second slot is associated with the first slot and is associated with a second intention, wherein the second intention is an associated intention of the first intention and is further associated with a second skill, and wherein the second skill is an associated skill of the first skill;
• modify the first entity to the second entity when the first entity is a pronoun;
• send, to a second server a first service request comprising first indication information of the first intention and the first entity, wherein the second server is an application server corresponding to the first skill;
• and
• obtain, from the second server and in response to the first service request, a first service result that is based on the first indication information and the first entity.
