49 results about "Semantic technology" patented technology

The ultimate goal of Semantic technology is to make the machine to understand the data. To enable the encoding of semantics with the data, well-known technologies are RDF (Resource Description Framework) and OWL (Web Ontology Language). These technologies formally represent the meaning involved in information. For example, ontology can describe concepts, relationships between things, and categories of things. These embedded semantics with the data offer significant advantages such as reasoning over data and dealing with heterogeneous data sources.

Knowledge graph-based cross-department early-diagnosis and decision support system for chronic kidney diseases

The invention discloses a knowledge graph-based cross-department early-diagnosis and decision support system for chronic kidney diseases. The system comprises a patient information model establishmentmodule, a patient information model library storage module, a knowledge graph association module, a knowledge graph reasoning module and a decision support feedback module. According to the invention, a patient information model is constructed, and an OMOP CDM standard term system is utilized to construct electronic medical record data of patients into the patient information model with unified concept codes and unified semantic structures; the advantages of a semantic technology in data interaction and expansion are given to play, so the system has better adaptability and expandability to heterogeneous data of different hospitals; and meanwhile, clinical suggestions obtained through knowledge reasoning based on the knowledge graph are originated from clinical guidelines and doctor experience conforming to evidence-based medicine, and reasoning process and suggestion reasons can be traced and acquired by constructing reasoning instances, so the reasoning process and the suggestion reason can be given while clinical suggestions are given, and the credibility of doctors to decision support suggestions is improved.

Semantic analysis technology-based sensitive public sentiment content recognition method and pre-warning system

The invention provides a semantic analysis technology-based sensitive public sentiment content recognition method and a pre-warning system. The method comprises the following steps of: importing a Chinese word segmentation standard lexicon, increasing a sensitive word vector library, classifying sensitive words, setting a core word as a standard word for each type of sensitive words, and setting distance vectors from other same-type words to the standard word by taking the standard word as a source node; carrying out voice recognition on an audio file, and recognizing sensitive words and related sentiment words; carrying out clustering analysis, recognizing sensitive words and sentiment words related to semantic meaning, and carrying out semantic analysis judgement; and recognizing and outputting sensitive contents. According to the method, the sensitive word vector library is established on the basis of a traditional natural language lexicon, and vector distance relationship among same-type sensitive words is established. In practical application field, sensitive content recognition and pre-warning can be automatically carried out on real-time communication contents or classroom teaching contents. By utilizing the method, sensitive sematic judgement can be realized and the correctness is greatly enhanced so that sensitive public sentiment content monitoring is realized.
