Problems solved by technology

However, keyword search cannot query structured data because only a few words are used to specify the query intent
In contrast, Structured Query Languages ​​such as SPARQL and GRAPHQL are expressive but too complex for the average user

Embodiment 1

[0036] Such as figure 1 As shown, a query method for intelligent human-computer interaction includes the following steps:

[0037] Step 1. Interact with the user through the graphical user interface to obtain query content.

[0038] Specifically, in this embodiment, the manner of interacting with the user includes but is not limited to using natural language, text, or voice.

[0039] Step 2. Using the entity extractor to extract entities from the natural language query provided by the user and understand the content of the user query.

[0040] Specifically, the implementation method of the entity extractor includes: realizing word graph scanning based on the prefix dictionary structure, establishing a directed acyclic graph for all possible word combinations, and finding the maximum possible combination of opportunity word frequency through dynamic programming, including Unknown vocabulary is handled using HMM-based models and the Viterbi algorithm.

[0041] As a preference...

Embodiment 2

[0052] An intelligent human-computer interaction query system, including:

[0053] The query acquisition module is used to provide a graphical interface to help users customize queries and interact with users;

[0054] An entity extractor module for extracting entities from user-supplied queries;

[0055] The query optimization module is used to further confirm the user's query requirements and optimize the query by asking the user questions;

[0056] A query result module for interacting with the knowledge base using the final optimized query and providing the final query result to the user;

[0057] The query acquisition module, the entity extractor module, the query optimization module, and the query result module are connected in sequence.

[0058] It should be noted that each module in this embodiment is logical. In a specific implementation process, one module can be split into multiple modules, and multiple modules can also be combined into one module.

[0059] The int...

Embodiment 3

[0062] This embodiment discloses a computer device, which may be a server, and the computer device includes a processor, a memory, a network interface, and a database connected through a system bus. Wherein, the processor of the computer device is used to provide calculation and control capabilities. The memory of the computer device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system, computer programs and databases. The internal memory provides an environment for the operation of the operating system and computer programs in the non-volatile storage medium. The database of the computer device is used to store the data involved in the query method of intelligent human-computer interaction. The network interface of the computer device is used to communicate with an external terminal via a network connection. When the computer program is executed by the processor, an intelligent human-computer interaction ...

Abstract

The invention discloses an intelligent man-machine interaction query method. The method comprises the following steps: interacting with a user through a graphical user interface to obtain query content; extracting entity understanding user query content from the query content; realizing fine adjustment user query through a query optimization method; query and feedback of query results. According to the method, an effective and friendly method is provided for obtaining the knowledge graph on the basis of the natural language question and answer interface, a familiar and visual mode is also provided for users to describe query, and therefore complex structured query languages are replaced.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction, in particular to an intelligent human-computer interaction query method, system, computer equipment and storage medium. Background technique [0002] A museum is a repository of artifacts and knowledge. A large and complex organizational structure charged with collecting, documenting and preserving artefacts from our past, as well as presenting and disseminating this knowledge to all people in creative, people-centred and interactive ways. In recent years, more and more museums are moving toward an interactive storytelling system designed to engage visitors and provide them with the right answers to questions. At the same time, with the development of knowledge graphs in recent years, a large amount of structured data has been acquired and maintained. However, with the increasing amount of data and the development of complex methods for retrieving information, it is a challen...
