Information processing device and information processing method

Abstract

The invention provides an information processing device and an information processing method, wherein the input of retrieval questions is received from the outside; the processing results of the retrieval questions are grouped; and then the result of grouping is output. The information processing device is provided with: a question analysis and retrieval item generation module (1300) for analyzing a retrieval question and generating a retrieval item; a document retrieval module (1400) for receiving the retrieval item generated by the question analysis and retrieval item generation module (1300) and performing document retrieval; a result extracting / filtering module (1500) for extracting the results of retrieval and filtering the results; and a result grouping module (1600) for grouping the filtered results.

Description

technical field [0001] The present invention relates to an information processing device and an information processing method, in particular to an information processing device and an information processing method for information retrieval and display. Background technique [0002] In the 21st century, people have entered the information age, and the demand for Internet information is also increasing day by day. The application of large-scale information retrieval technology and search engines has improved people's ability to obtain information to a certain extent. However, the inherent characteristics of the Internet, such as massive, heterogeneous, and invalid data, reduce the accuracy and efficiency of people's access to information. In order to improve user experience, mainstream information retrieval systems have made certain achievements in technologies such as user retrieval needs analysis, retrieval methods, and result presentation.

Problems solved by technology

However, due to the inconsistency between the "correlation" and the user's expected "result", the "result" expected by the user may be distributed in various positions of the list, which has two limitations: 1. The top-ranked web pages often have many Similarity, pointing to the same result, which wastes user's time clicking and reading the page

2. If the web pages with different "results" are ranked at the bottom, it is often difficult for users to see them, which results in the loss of retrieved information

However, due to the diversity of information representations on the Internet, the richness of content, and the limitation of computer reasoning capabilities, it is difficult for question answering systems based on the vast Internet to return concise and accurate answers.

In practical applications, the answer source of the question answering system is mainly a specific knowledge base, so its application field is limited
