Method, system and storage medium for implementing intelligent question answering

A system for implementing intelligent question answering, comprising:

• at least one processor;
• and
• a memory storing instructions, which when executed by the at least one processor, cause the at least one processor to perform operations, the operations comprising:
• receiving a query question;
• performing a semantic analysis of the query question by analyzing the query question to obtain a dependency syntax tree that describes a dependency relationship between various portions of the query question;
• performing corresponding search processing for the query question based on a result of the semantic analysis, the corresponding search processing comprising search processing performed for the query question by a text library search system;
• and
• returning an answer based on a result of the corresponding search processing,
• wherein the performing the search processing for the query question by the text library search system comprises:
• performing a search to obtain a document set related to the query question;
• calculating document correlation of documents in the document set;
• searching the document set for a candidate segment based on the document correlation, the candidate segment comprising a candidate answer;
• and
• extracting the candidate answer from the candidate segment, and performing a first ranking operation;
• wherein performing the first ranking operation comprises:
• performing ranking based on at least one feature of a uniform resource locator (URL) weight, and an offset weight, the URL weight being a weight of a URL link and a site to which a document where the candidate answer is located belongs, and the offset weight being a distance coefficient of the candidate answer with respect to a keyword in the query question in different candidate segments.

A non-volatile computer storage medium storing one or more modules, the one or more modules which when executed by a device, cause the device to perform a method for implementing intelligent question answering, the method comprising:

• receiving a query question;
• performing a semantic analysis of the query question by analyzing the query question to obtain a dependency syntax tree that describes a dependency relationship between various portions of the query question;
• performing corresponding search processing for the query question based on a result of the semantic analysis, the corresponding search processing comprising search processing performed for the query question by a text library search system;
• and
• returning an answer based on a result of the corresponding search processing,
• wherein the performing the search processing for the query question by the text library search system comprises:
• performing a search to obtain a document set related to the query question;
• calculating document correlation of documents in the document set;
• searching the document set for a candidate segment based on the document correlation, the candidate segment comprising a candidate answer;
• and
• extracting the candidate answer from the candidate segment, and performing a first ranking operation;
• wherein performing the first ranking operation comprises:
• performing ranking based on at least one feature of a uniform resource locator (URL) weight, and an offset weight, the URL weight being a weight of a URL link and a site to which a document where the candidate answer is located belongs, and the offset weight being a distance coefficient of the candidate answer with respect to a keyword in the query question in different candidate segments.
