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:

Electronic data interchange Electronic data interchange (EDI) is an electronic communication system that provides standards for exchanging data via any electronic means. 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.

Categories, Links, and Tags Ontology is Overrated: Categories, Links, and Tags This piece is based on two talks I gave in the spring of 2005 -- one at the O'Reilly ETech conference in March, entitled "Ontology Is Overrated", and one at the IMCExpo in April entitled "Folksonomies & Tags: The rise of user-developed classification." The written version is a heavily edited concatenation of those two talks. Ralph Debusmann - Extensible Dependency Grammar (XDG) Extensible Dependency Grammar (XDG) is a general framework for dependency grammar, with multiple levels of linguistic representations called dimensions, e.g. grammatical function, word order, predicate-argument structure, scope structure, information structure and prosodic structure. It is articulated around a graph description language for multi-dimensional attributed labeled graphs. An XDG grammar is a constraint that describes the valid linguistic signs as n-dimensional attributed labeled graphs, i.e. n-tuples of graphs sharing the same set of attributed nodes, but having different sets of labeled edges. All aspects of these signs are stipulated explicitly by principles: the class of models for each dimension, additional properties that they must satisfy, how one dimension must relate to another, and even lexicalization.

WebEDI - Glossary 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. Documents that are processed regularly can be automated when by electronically. The information contained in these documents are sent in files such as Tradacoms, Edifact and XML. Visualizing Del.icio.us Roundup I have been coming across many del.icio.us tools to visualize usage during my daily researching hours. So many, that I have decided to start making note of the ones I come across. From the span of about two weeks, I have been collecting as many as I could find. I will list each one along with a description. Enjoy!

GAJIT This page is for a mini-project I undertook when I had a spare moment or two to port the C++ based genetic algorithm library GAGS to Java. GAJIT (Genetic Algorithm Java Implementation Toolkit) is a rather contrived name for a simple set of classes that I wrote to experiment with genetic algorithms. I became interested in genetic algorithms and wanted to experiment with them. I first downloaded J. J.

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. Information and knowledge can be expressed in such a way that it is computer-interpretable, as well as system-independent and natural language independent. Tag (metadata) Tagging was popularized by websites associated with Web 2.0 and is an important feature of many Web 2.0 services. It is now also part of some desktop software.

Speech Recognition By Java - Simplified | Osama Oransa's Blog Speech recognition is one of the challenging areas in computer science, a lot of pattern recognition methodology tried to resolve a good way and higher percentage of recognition. One of the best ways to be use is Hidden Markov Model : "The process of speech recognition is to find the best possible sequence of words (or units) that will fit the given input speech.

Global Health Delivery Online: Improving health care delivery through global collaboration Hi All, I volunteer with a clinic in rural India and we have had issues in providing continuity of care to the patients that we see. Our current medical record system consists of a paper card that the patients are instructed to bring with them when they come back for further care. This works reasonably well when they remember to bring the card with them, but we have many individuals who chronically forget. I have played with the idea of using an EMR like OpenMRS to help us solve this problem, but we are also in an area where addresses, government-issued ID numbers, or other unique identifiers are either non-existent or unreliable and there are many people with the same name in our patient population. Age is also notoriously unreliable.
