specific Embodiment approach 1

[0061] A DHI report interpretation method based on a knowledge map described in this embodiment includes the following steps:

[0062] 1. Construction of DHI Domain Knowledge Graph:

[0063] (1) Construct DHI domain ontology, such as figure 1 As shown, the DHI domain ontology includes three types of entities and entity relationships: "performance indicators / symptoms", "influencing factors", and "solution measures"; Symptoms exhibited by cows;

[0064] For example, if the performance index is "abnormal somatic cells", one of the influencing factors is the problem of feed ingredients, which may also show symptoms such as "low milk fat rate" and "increased incidence of hoof disease";

[0065] (2) The electronic text obtained after digitizing the professional books and literature related to DHI measurement and application guidance is used as the labeling object, and the ontology is used as the labeling basis to carry out semantic labeling on the electronic text data to form labe...

Embodiment

[0086] (1) According to the DHI report of a ranch this month, the average milk fat rate of the whole herd is 4.24%, the milk protein rate is 2.76%, and the fat-to-egg ratio is 1.54; the average urea nitrogen level of the high fat-to-egg ratio cattle is 22.33 mg / 100ml;

[0087] (2) The standard range of fat-to-egg ratio is 1.12-1.30, and the fat-to-egg ratio of this herd is 1.54>1.30. It is determined that the problem of "high fat-to-egg ratio" exists in this herd, corresponding to the fact description of "high fat-to-egg ratio" ;The standard range of urea nitrogen level is 10-18 mg / 100 ml, and the average urea nitrogen level of cattle with high fat-to-protein ratio in this herd is 22.33 mg / 100 ml>18 mg / 100 ml. The problem of "too high level" corresponds to the fact description of "the level of urea nitrogen in high-fat egg ratio cattle is too high";

[0088] (3) According to the DHI field knowledge map, according to the index of "high fat-to-egg ratio", the preliminary posit...

Abstract

The invention discloses a DHI report interpretation method and system based on a knowledge graph and a storage medium, and belongs to the technical field of livestock breeding. The method aims at solving the problems that an automatic interpretation method for the DHI report does not exist at present, so that the interpretation efficiency of the DHI report is low, and the information of the DHI report cannot be objectively, accurately and effectively utilized. According to the method, DHI index data is analyzed based on DHI data of a pasture, problem diagnosis is carried out on a dynamic analysis result in combination with a DHI domain knowledge graph, and the problem diagnosis process comprises problem positioning, that is, based on the DHI domain knowledge graph, the fact description of dynamic analysis is used as an entity of 'a performance index / symptom'; and the probability that the fact description is influenced by a certain influence factor is obtained through calculation, and the DHI domain knowledge graph comprises three types of entities and entity relations of 'performance indexes / symptoms', 'influence factors' and 'solutions'. The method is mainly used for DHI report interpretation.

Description

technical field [0001] The invention relates to a DHI report interpretation method and a system, that is, a storage medium, and belongs to the technical field of animal husbandry. Background technique [0002] DHI (Dairy Herd Improvement) performance measurement of dairy cows is of great significance to guide the improvement of dairy herds in pastures. At present, the DHI report has the following problems in practical application: [0003] (1) The interpretation of the DHI report has not yet formed a standardized knowledge system. This knowledge is only expert experience or recorded in some professional books, which is fragmented and cannot be fully used to guide the analysis of the DHI report; [0004] (2) Due to the problem (1), there is a large gap in personnel who can interpret the DHI report professionally. Most of the pastures completely rely on the preliminary interpretation report issued by the DHI testing center based on the test results. The report only makes a ro...
