. Includes 5 basic primitive classes (classes), relationships (relations), functions (functions), axioms (axioms), and instances (instances). Among them, classes can also be called concepts.Three, the expression of the ontologyThe so-called ontology of the expression is to describe the language of the ontology, currently used to describe the ontology of the language as many as 30, of which the most commonly used is the four types of ontology representation language, which are

patterns.Semantic Web Development Framework Jena SQL Database engine SDB uses a hybrid model that stores ontology content in 4 interconnected data tables: node table nodes, prefix table prefixes, four-tuple table quads, and ternary table triples. SDB treats the ontology as a collection of graphs, subject, predicate, and object in RDF are nodes in the graph, and a dataset can have multiple graphs. Therefore, as the name implies, nodes stores the node

When using Jena to develop ontology applications, we first need to use ontology building tools, such as protege, to build ontology files such as owl, RDF and so on to read and parse the ontology model. The corresponding code is given below, please correct me in the wrong place.(Based on Jena 2.13.0,jena 3 requires Java 1.8)Mode one: Use Rdfdatamgr /** * Use Rdfdatamgr to read RDF files *@pa

Rss To discuss the technology related to blog, it is necessary to talk about RSS, the abbreviation in English can have several sources, and by different technical groups do different interpretations. It can be either "Rich Site Summary" or "RDF site Summary" or "Really Simple Syndication". Why do you have so many meanings? This is also from the RSS section of the relationship today is not clear. Someone must remember today that IE 4 just came out with

user's retrieval needs and resource content, such as and OR. The current dominant keyword model: the word bag model. It works well for theme searches, but not for more complex information retrieval needs . The database (DB) and Knowledge Base expert system (Knowledge-based expert system) can provide more accurate answers (data retrieval). It uses a more expressive model to represent the needs of the user, take advantage of the intrinsic structure and semantic associations between the data, allo

Author: Rainkero After Ubuntu8.04.1 is installed, Baidu souzang only supports version 2.0 because its Firefox version is. Baidu officially did not release new extensions to support updates, so it had to modify the plug-in configuration on its own to use Baidu souzang in firefox3.

This article mainly introduces RSS processing in Python. This article is from the IBM official Developer Technical Documentation. if you need it, refer to RSS, which is short for multiple extensions: "RDF Site Summary", "truly Simple Syndication", and "Rich Site Summary )", other extensions may also be used for representation. Behind such a chaotic name, you will find that stories related to such an ordinary technology field are surprising. RSS is a s
