Description
Technical Field
The invention relates to an image data target identification enhancement method based on a data map, an information map and a knowledge map framework. The method is mainly used for solving the problem that the existing image recognition method cannot recognize the image recognition of the unmarked category in the training set, and belongs to the cross field of distributed computing and software engineering technology.
Background
Knowledge-graph has become a powerful tool for representing knowledge in the form of labeled directed graphs and can impart semantics to textual information. A knowledge graph is a graph constructed by representing items, entities or users in the form of nodes and linking nodes that interact with each other in the form of edges, where the edges between nodes can represent any semantic relationship. The construction of the knowledge graph is divided into three levels of information extraction, knowledge fusion and knowledge processing according to the knowledge acquisition process, the defined knowledge graph is a mesh knowledge base formed by connecting entities with attributes through relations, and the research value of the knowledge graph is that information accumulated in the Internet can be organized into available knowledge at the minimum cost, so that concept retrieval and graphical knowledge display are realized through reasoning. Data is obtained by observing numbers or other basic individual items. Information is conveyed by the context of data and data combinations, suitable for analysis and interpretation. Knowledge is a general understanding and experience derived from the accumulated information from which new context can be inferred.
The most traditional image recognition technology is manual recognition, a marked image can be recognized by a deep learning method, an equation is gradually simulated by a machine in the process of repeatedly recognizing the same type of object, the equation is close to the common characteristic of the recognized object, and the recognition purpose is finally achieved, but the recognition problem of the unmarked image cannot be solved by the deep learning method. The invention mainly identifies the unidentified objects as much as possible by the aid of the data map, the information map and the knowledge map.

The system structure is as follows: the method comprises the steps of firstly establishing a data map, an information map and a knowledge map framework aiming at a recognized image, traversing the data map aiming at An unrecognized image A to obtain a data matching degree R (Ai) with Ai, and selecting initial matching results A1, A2, \ 8230An according to the sequence of R (Ai) from large to small; and (3) carrying out relation matching on the initial matching result and the identified image set { B } in an information map to obtain relation matching degrees Y (Ai) and X (Ai), selecting A1, A2, \8230Akaccording to the sequence of X (Ai) from large to small, and carrying out calculation and inference on Ai' and { B } in the knowledge map to obtain a result with the highest reliability. At present, the identified images can be identified by deep learning, and on the basis, the invention introduces a data map, an information map and a knowledge map framework to carry out knowledge reasoning on the unidentified images, thereby realizing the automatic and intelligent identification of the images in the pictures or the images shot by the camera. Specific explanations for constructing the data map, the information map and the knowledge map are given below:
data mapping: data maps can record basic attributes in an image entity, including color morphology, etc., but they are not meaningful by themselves without contextual context. The data map can be expressed by data structures such as arrays, linked lists, queues, trees, stacks, graphs and the like. The data map may also record the frequency of appearance of structures contained in the image entities, including the frequency of the three levels of structure, time and space. The data map can describe the degree of closeness of the association of different image entities, which is called as density, and can reflect which entities are closely associated and which entities are sparsely associated. However, the data map can only be used for static analysis, and cannot express the interaction relationship between entities. Meanwhile, the data map does not analyze the accuracy of the data, different entities may appear but represent the same meaning, such as tomatoes and tomatoes, and the attribute frequencies of the two image entities are the same, so that data redundancy is generated;
an information map: information is conveyed by context after data and data combination, information that is suitable for analysis and interpretation after concept mapping and correlation combination. The information map may be expressed according to a relational database. And (4) performing data cleaning on the information map to eliminate redundant data. The information map can record the interaction relation between the entities;
knowledge graph: the knowledge graph further improves the semantic relation between the entities according to the data graph and the information graph, the edge density and the node density of the knowledge graph are improved through information reasoning and entity linking, and the unstructured characteristic of the knowledge graph enables the knowledge graph to be seamlessly linked. Information reasoning needs to be supported by relevant rules, and the accuracy Cr of a new relationship obtained through reasoning can be obtained by formula 1. The new relationship between entity 1 and entity 2 may be represented asAnd z represents all of the relationships,representing a new relationship weight, representing a relationship between entity 1 and entity 2, which relationship is considered valid when accuracy exceeds a threshold
(1)。
