The invention discloses an ontology-based architectural pattern modeling method. According to the method, description logic is used to perform concept modeling of an architectural pattern, a domain knowledge model is further introduced, finally a mapping relation between a high-level abstract concept and system realization is established, and therefore the model is applied to recognition of the architectural pattern. Considering extension and reuse problems of domain knowledge, the domain knowledge is organized into a netlike hierarchical structure during modeling. In the structure, a conceptmodel is at a high level, more domain knowledge is combined step by step at all lower levels to explain the high-level concept. New knowledge can be incrementally added into any node at any level andalso can be selectively reused to establish a new concept. The ontology-based architectural pattern modeling not only has the abstracting ability of concept modeling but also can utilize the domain knowledge to serve architectural pattern recognition, and therefore the automation degree and precision of architectural pattern recognition are improved.

In a method of managing knowledge, existing knowledge is captured in a predetermined format of selected information categories, the captured knowledge is organized into an indexed database of information including links between related information, new knowledge is acquired and captured in the predetermined format, and the database is updated to include the new information and links between the new information and related information.

The invention provides a knowledge network oriented to autonomous service, and a construction method thereof. The network is a knowledge network based on a flat structure. The network processes data collected by sensor nodes of an underlying network by constructing unified middle layer elements, and provides API interfaces for upper layer service to access; the middle layer elements are used for inquiring and accessing the sensor nodes based on a regional mode, and collecting data; the middle layer elements form reticular or annular structures which are on the same plane through logical connection; the upper layer application service only needs to access a certain element in the middle layer to obtain required information. The middle layer elements belong to a knowledge organization management layer which is composed of a plurality of KMC elements intercommunicated for knowledge exchange; the KMC elements are entities containing knowledge; the upper layer application service accesses the KMC elements exclusively connected with the KMC elements by calling the API interfaces; meanwhile, the KMC elements are connected with the corresponding KMC elements according to different knowledge requirements.

The invention provides a building method and device for a specialized database. The method comprises the following steps: creating a target professional database; adding a neighborhood body corresponding to the target professional database into the target professional database in order to serve as a knowledge organization system of a target database; acquiring multiple knowledge entries; buildingassociation relations between all the knowledge entries and knowledge elements in the neighborhood body; and building data indices for the knowledge entries and the target professional database. Because the neighborhood body can provide more accurate and complete data association relations, the neighborhood body is taken as a knowledge organization system of the professional database and association relations between the knowledge entries and the knowledge elements in the neighborhood body are established. Therefore, association relations of all resources in the overall professional database are more complete. Resources content are more comprehensive. Recommendation and retrieval results are more improved. The professional database is built in an automated manner so that creating time is reduced.

The invention discloses a finance and tax knowledge metadata classification conversion and storage method, which relates to the technical field of data conversion and storage. According to the method, all finance and tax knowledge information in a target range is converted into metadata from text information; and meanwhile, an original knowledge system framework is broken through and storage is performed by a minimum unit (a paragraph and even each sentence), namely, all the finance and tax knowledge information in the target range is converted into the metadata from the text information, so that further a specific calculation method can be abstracted from the metadata according to a business rule. Simply speaking, when a user tells a platform to prepare for developing which of businesses, the platform performs automatic analysis and calculation, lists out all tax-related processing possibilities of the business, calculates a specific tax amount and cash flow, and prompts operation key points and risk factors, thereby realizing intelligentization of finance and tax knowledge organization.
