The invention discloses a semantic encoding / decoding method based on knowledge graph sharing, equipment and a communication system, and belongs to the field of wireless communication. The invention provides three brand-new semantic communication architectures based on knowledge graph sharing, and is expected to become a foundation stone of a 6G technology in the future. Semantic communication mainly depends on a semantic knowledge base which is established between a human user and a machine and has universality and understandability, so that the problem of incompatibility caused by inconsistent information modes in the current machine-machine intelligent connection is expected to be solved, and a foundation is laid for establishing a unified communication protocol architecture capable of meeting intercommunication and interconnection among different types of equipment. Secondly, semantic communication is based on human universality knowledge and a semantic system, so that user service experience during interaction and communication of human-machine intelligent connection and human-human intelligent connection can be fundamentally guaranteed, the number of times of conversion between semantic signals and physical signals is further reduced, and possible semantic distortion is reduced.

A method and a scripting paradigm for automatically integrating disparate information systems (e.g., web services and databases) within a given enterprise into a service-oriented architecture. A script writer generates a script using a scripting paradigm, and the resulting script automatically derives new data models, new ontological structures, new mappings, and a new web service that integrates disparate information systems. In addition to integrating disparate information systems, the scripts may be harvested to automate the metadata discovery and retrieval process. The scripting paradigm builds upon existing open-source scripting languages and is compatible with existing internet browsers, thus encouraging mass participation in the integration process.

As medical imaging becomes more affordable, and the diversity of diagnostic modalities and therapeutic treatments increase, the amount of data being stored increases, and the problem becomes even more critical. One approach to improve retrieval efficiency of images is to employ semantics to establish a defined set of search and classification terms. However, such semantic systems still require the user to make a selection of the most appropriate term or terms to classify a report or image, and the accuracy of the results are thus dependent on the skill and knowledge of the classifier. According to a first aspect of the invention, a retriever is provided for retrieving a medical image having a searchable attribute, the retriever being configured to interface with a semantic database and an image database, and wherein the searchable attribute is determined by segmenting the medical image, using the anatomical model.

The invention discloses an image-text double-coding mechanism implementation model based on a CR2 neural network, and relates to the field of human cognition and knowledge representation. The image-text double-coding mechanism implementation model based on the CR<2> neural network is characterized in that the implementation model includes a representation system which adopts a multilayer Convolutional Neural Network (CNN) model to obtain ''image units'' representing mental images of information; and a semantic system which adopts an RNNLM language model to obtain ''language units'' representing information semantics; a reference association system which adopts an RBF self-propagation neural network model, wherein a positive model uses the ''image units'' as input, output is the ''language units'' associated for reference, and an inverse model is inverse operation of the positive model. Here the CR<2> neural network refers to an organic composition of three neural networks of CNN, RNN and RBF. The image-text double-coding mechanism implementation model based on the CR2 neural network realizes establishment of models of an image representation system and a natural language semantic system, and also establishes a model of reference association between the two systems. The models completely simulate the whole process of an image-text double-coding cognition mechanism.

The embodiments of the present invention provide a computer-implemented method and system for translating user keywords into semantic queries based on domain vocabulary. The system receives the user keywords and search for the concepts. The concepts are transformed into a connected graph. The user keywords are translated into precise access paths based on the information relationship described in conceptual entity relationship models and then converts these paths into logic based queries. It bridges the semantic gap between user keywords and logic based structured queries. It enables users to interact with the semantic system by articulating the information in a structured query language. It improves the relevance of search results by incorporating semantic technology to drive the mechanics of the search solution.
