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, whi

Embodiment approach 1

[0046] Such as figure 2 As shown, the information processing device 100 includes a database 1100, a question input module 1200, a question analysis and retrieval item generation module 1300, a document retrieval module 1400, a result extraction and filtering module 1500, a result grouping module 1600, and a grouping result analysis and report generation module 1700 and a display module 1800.

[0047] The database 1100 is used to store question-and-answer pattern databases, semantic dictionary databases, and the like. Provide question mode for question analysis and retrieval item generation module 1300 , provide semantic knowledge support for document retrieval module 1400 , provide semantic knowledge support and answer mode for result extraction and filtering module 1500 and result grouping module 1600 .

[0048] The input module 1200 is used to receive the questions input by the user, check the normativeness of the input questions, and ensure that the questions in the corre...

Embodiment approach 2

[0134] Figure 11 It is a block diagram of an information processing device according to another embodiment of the present invention. The information processing device 200 includes: a question classification module 2100 , a sentence similarity-based result extraction module 2200 , a result grouping module 2300 , and a display module 2400 .

[0135] The question classification module 2100 is used to find the corresponding question category for the input question. Each question category corresponds to a specific answer type.

[0136] The sentence similarity-based result extraction module 2200 is used to retrieve the result of the input question from the document to be retrieved.

[0137] The modules 2100, 2200, 2300, and 2400 are further described in detail below with examples.

[0138] Such as Figure 12As shown, the processing flow of the problem classification module 2100 is divided into an offline training step and an online prediction step. The off-line training step i...

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. [0003] Traditional search engi...
