US 11,455,553 B2 · Quality-based scoring and inhibiting of user-generated content

Abstract

Methods and devices for assessing the quality of user-generated content are described. In one embodiment, a method is disclosed for measuring the quality of a user-generated answer to a question by combining various factors, including question-answer surface word vector similarity, question-answer explicit semantic analysis vector similarity, answer-answer explicit sematic analysis vector similarity, query performance predictor, sentiment analysis, textual analysis of the answer, and reputation of the answerer. The method uses a learning procedure to determine the best algorithm for measuring the overall quality of the answer based on these factors.

Dependent claims

A method for displaying answers to a question, comprising:

computing an overlap between a question vector associated with a question text and each of N answer vectors associated with N answer texts associated with the question text to obtain a set of N measures of question-answer similarity;
determining a quality ranking of the N answer texts based at least partially on the set of N measures of question-answer similarity;
and
displaying one or more of the N answer texts on a user interface in an order based at least partially on the quality ranking.

1 more element

A community question-answering server, comprising:

a database storing N answer texts associated with a question text associated with a question vector, wherein N is an integer greater than one;
a processing unit configured to:
compute an overlap between the question vector and each of N answer vectors associated with the N answer texts to obtain a set of N measures of question-answer similarity;
and
determine a quality ranking of the N answer texts based at least partially on the set of N measures of question-answer similarity;
and
an output interface for causing a display of one or more of the N answer texts on a user device in an order based at least partially on the quality ranking.

4 more elements

A non-transitory computer-readable storage medium having stored therein instructions that, when executed by a processor of a server, cause the server to:

compute an overlap between a question vector associated with a question text and each of N answer vectors associated with N answer texts associated with the question text to obtain a set of N measures of question-answer similarity;
determine a quality ranking of the N answer texts based at least partially on the set of N measures of question-answer similarity;
and
display one or more of the N answer texts on a user interface in an order based at least partially on the quality ranking.
