The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
Example 1:
referring to fig. 1, the present embodiment provides a prompting system, a prompting method, a computer, and a waste accommodating device, where the prompting system includes a first obtaining unit, a second obtaining unit, a determining unit, a receiving unit, and an output unit, and generates, based on a garbage knowledge graph, graph grids associated with each other in the determining unit, where each node of the graph grids has corresponding node information.
The first obtaining unit is used for obtaining keywords in the user question information, the second obtaining unit is used for obtaining target nodes of a map grid corresponding to the keyword information, the judging unit is used for judging whether the target nodes have child node groups, and if no child node group exists, a top father node of the target nodes is used as reply information; if the child node group exists, the top parent node corresponding to the child node in the child node group is used as reply information, the receiving unit is used for receiving question information of a user, and the output unit is used for outputting the reply information.
The prompting method comprises the following steps:
step S01, obtaining keyword information in the user question content;
step S02, determining the target node of the map grid corresponding to the keyword information;
step S03, judging whether the target node has a child node group;
step S041, if the child node group does not exist, the top parent node of the target node is used as reply information;
step S402, if the child node group exists, the top parent node corresponding to the child node in the child node group is used as reply information.
Specifically, receiving question information of a user, analyzing the question information, acquiring a keyword from the question information of the user according to a word sequence recorded by a node in a graph grid, comparing the word sequence in the node information of the graph grid with the word sequence of the keyword, determining the matching degree of each node in the graph grid with the keyword, and taking the node corresponding to the node information with the highest matching degree as a target node; when the user question information has a plurality of keywords, each keyword is judged respectively, a target node corresponding to each keyword is determined, and then each target node is judged respectively.
Judging whether a target node has a child node group, if the target node does not have the child node group, using a top parent node corresponding to the target node as response information, if the target node has the child node group, further judging, judging the number of first child nodes in the child node group, namely the target node can be provided with one, two or more parallel first child nodes, calculating the depth of three nodes of each first child node, using the node information of the depth of three nodes within the depth of each first child node as response information, then transmitting the response information to an output end, and outputting the response information by the output end in a voice playing mode or a text mode for a user to refer.
The prompting method in the scheme can be applied to garbage classification information prompting, map grids are built according to garbage maps, and when the question information of a user is received, the response information can be quickly and accurately made. Examples are: and acquiring keywords in the user question information, and when the keywords hit a target node, and the node has no child node such as 'waste electrical appliance', directly adopting a top father node as an answer such as 'recoverable article'.
If the target node has child nodes, the top father nodes of the two nodes are searched as answers, if the question information is that the durian is garbage, the durian node is hit, the top father node of the node is searched for wet garbage, and meanwhile the child node is searched for skin, and the top father node is dry garbage, so that the answer is that the durian meat belongs to the wet garbage and the durian skin belongs to the dry garbage.
The scheme also provides a computer which comprises a processor, wherein the processor can output answer information by adopting the prompting method.
This scheme still provides a wastes material accommodate device, including above-mentioned computer device, wastes material accommodate device has a plurality of mutually independent accommodation space, and the user can be customized to every accommodation space, if hold dry rubbish, wet rubbish, recoverable rubbish and can not retrieve rubbish etc. when not knowing the rubbish type, the user can adopt the mode of asking questions to acquire the rubbish type to put into corresponding accommodation space with rubbish.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
