Gellish. Gellish is a formal language that is natural language independent, although its concepts have 'names' and definitions in various natural languages.


Any natural language variant, such as Gellish Formal English is a controlled natural language.


Semantic Web. I have an idea that I think is very important but I haven’t yet polished to the point where I’m comfortable sharing it.

Semantic Web

I’m going to share it anyway, unpolished, because I think it’s that useful. So here I am, handing you a dull, gray stone, and I’m saying there’s a diamond inside. Maybe even a dilithium crystal. My hope is that a few experts will see what I see and help me safely extract it. Or maybe someone has already extracted it, and they can just show me.

The problem I’m trying to solve is at the core of decentralized (or loosely-coupled) systems. RDF offers a solution to this, but it turns out to be pretty hard to put into practice.

The Association Ontology Specification

This copyright applies to the Association Ontology Specification and accompanying documentation in RDF. Regarding underlying technology, the Association Ontology uses W3C's RDF technology, an open Web standard that can be freely used by anyone. The Association Ontology specification provides basic concepts and properties for describing specific association statements to something, e.g. an occasion, a genre or a mood, and enables furthermore, a mechanism to like/rate and feedback these associations in context to something on/ for the Semantic Web.

This document contains a RDFa description of the Association Ontology and some additional information and examples. Status of This Document. Watson Semantic Web Search. This is the Watson Web interface for searching ontologies and semantic documents using keywords.

Watson Semantic Web Search

This interface is subject to frequent evolutions and improvements. If you want to share your opinion, suggest improvement or comment on the results, don't hesitate to contact us... At the moment, you can enter a set of keywords (e.g. "cat dog old_lady"), and obtain a list of URIs of semantic documents in which the keywords appear as identifiers or in literals of classes, properties, and individuals. You can also use "jokers" in the keywords (e.g., "ca? Search options allow you to restrict the search space to particular types of entities (classes, properties or individuals) and to particular elements within the entities (local name, label, comment or any literal). Navigation in the results follows very simple principles.

Sign appears, it can be used to display additional information about the element it is attached with.

W3C Tutorial on Semantic Web and Linked Data at WWW 2013. Semantics. Montague grammar[edit] In the late 1960s, Richard Montague proposed a system for defining semantic entries in the lexicon in terms of the lambda calculus.


In these terms, the syntactic parse of the sentence John ate every bagel would consist of a subject (John) and a predicate (ate every bagel); Montague demonstrated that the meaning of the sentence altogether could be decomposed into the meanings of its parts and in relatively few rules of combination. The logical predicate thus obtained would be elaborated further, e.g. using truth theory models, which ultimately relate meanings to a set of Tarskiian universals, which may lie outside the logic. Semantic Web Primer. Semantic data model. Semantic data models.[1] A semantic data model in software engineering has various meanings: It is a conceptual data model in which semantic information is included.

Semantic data model

This means that the model describes the meaning of its instances. Such a semantic data model is an abstraction that defines how the stored symbols (the instance data) relate to the real world.[1]It is a conceptual data model that includes the capability to express information that enables parties to the information exchange to interpret meaning (semantics) from the instances, without the need to know the meta-model. Such semantic models are fact oriented (as opposed to object oriented). Typically the instance data of semantic data models explicitly include the kinds of relationships between the various data elements, such as <is located in>. Overview[edit] J.H. ter Bekke tribute site. Intro Johan ter Bekke developed a new data modeling approach based on semantic principles resulting in inherently specified data structures.

J.H. ter Bekke tribute site

A singular word or data item hardly can convey meaning to humans, but in combination with the context a word gets more meaning. In a database environment the context of data items is mainly defined by structure: a data item or object can have some properties ("horizontal structure"), but can also have relationships ("vertical structure") with other objects. In the relational approach vertical structure is defined by explicit referential constraints, but in the semantic approach structure is defined in an inherent way: a property itself may coincide with a reference to another object.

This has important consequences for the semantic data manipulation language. Semantic Data Modeling Principles. RoleofTripleSpaceinSemanticWebServices. The Voice of Semantic Technology Business: Big Data, Linked Data, Smart Data. - P.Solutions - Informationstechnologien GmbH. Ontology (information science) In computer science and information science, an ontology formally represents knowledge as a hierarchy of concepts within a domain, using a shared vocabulary to denote the types, properties and interrelationships of those concepts.[1][2] Ontologies are the structural frameworks for organizing information and are used in artificial intelligence, the Semantic Web, systems engineering, software engineering, biomedical informatics, library science, enterprise bookmarking, and information architecture as a form of knowledge representation about the world or some part of it.

The creation of domain ontologies is also fundamental to the definition and use of an enterprise architecture framework. The term ontology has its origin in philosophy and has been applied in many different ways. The word element onto- comes from the Greek ὤν, ὄντος, ("being", "that which is"), present participle of the verb εἰμί ("be"). According to Gruber (1993): Common components of ontologies include: Documentation for SWPortal Ontology - Semantic Web Portal Ontology. Electronic data interchange. Electronic data interchange (EDI) is an electronic communication system that provides standards for exchanging data via any electronic means.

Electronic data interchange

By adhering to the same standard, two different companies, even in two different countries, can electronically exchange documents (such as purchase orders, invoices, shipping notices, and many others). EDI has existed for more than 30 years, and there are many EDI standards (including X12, EDIFACT, ODETTE, etc.), some of which address the needs of specific industries or regions. It also refers specifically to a family of standards. In 1996, the National Institute of Standards and Technology defined electronic data interchange as "the computer-to-computer interchange of strictly formatted messages that represent documents other than monetary instruments.

EDI: Electronic Data Interchange Electronic data interchange (EDI) is a method of businesses sending and recieving documents to one another electronically, as opposed to using paper.
