 +===== 1. Some definitions =====
 +==== What is a taxonomy? ====
  
-===== 1. The taxonomic dictionary content =====+A taxonomy is a hierarchical network of concepts, in which each concept is related to one or more other concepts that are its supertype concepts. The top of the total hierarchy is the concept '​anything'​. A domain taxonomy is a taxonomy for a particular domain that has one or more top level concepts that are subtype-concepts of anything.\\  
 +A subtype-supertype relation is also called a specialization-generalization relation and can be denoted by the phrase <is a kind of> or synonymous phrases.\\  
 +If a subtype concept is qualitative or is a value, then the kind of relation between the qualitative value and its conceptual supertype concept can be specified by a relation that is a specialization of such a subtype-supertype relation and is called a qualitative subtype relation. It is denoted by the phrase 'is a qualitative subtype of'.\\  
 +If a subtype concept is a manufacturers model or model and size, then the kind or relation may be specified by a further subtype of the qualitative subtype which is denoted by the phrase 'is a manufacturers model of'.\\  
 +Examples of subtype-supertype relations are:  
 +  * centrifugal pump <is a kind of> pump 
 +  * man <is a kind of> person 
 +  * red <is a qualitative subtype of> color 
 +  * Ford mustang <is a manufacturers model of> car 
 +In Gellish, the concepts are represented by language independent unique identifiers that enable that each concepts is denoted by one or more names, synonyms, codes, abbreviations and translations.
  
 +==== What is a taxonomic dictionary? ====
  
-[[:​gellish_english_dictionary|Gellish ​taxonomic dictionary]], such as the dictionary of Formal English, ​is an electronic '​smart' ​dictionary ​and taxonomy and ontology. This means that it contains definitions ​of concepts, ​each of which is identified by unique identifier (UID) and can be referenced by one or more '​names'​ (termsincluding synonyms, abbreviations and codes) and includes relations between concepts, among others subtype-supertype relations. The vocabulary of the formal language, being the names of conceptsare mainly normal natural language terms, many of them can also be found in ordinary English dictionaries. All definitions satisfy the [[:​proper_definition_of_a_concept|rules for proper definitions]] of concepts in Gellish. This means that every concept not only has a textual definition, but also that they have at least an explicit relation with its supertype concept(s) ​and thus together they form a consistent subtype-supertype hierarchy of concepts or taxonomy. The [[:​gellish|Gellish Modeling Methodology]] provides guidelines for the extension of the taxonomic dictionary and for the creation of taxonomic dictionaries or just vocabularies in other languages. Such extensions or replacements may lead to separate [[:​proper_definition_of_a_concept|domain dictionaries]] for specialized application areas. As long as the common unique identifiers are used, the availability of vocabularies in various languages enable [[:​automated_translation|automated translation]] of Gellish expressions or presentations ​in a generalized user interface.+A taxonomic dictionary is dictionary of which each lemma represents a name of a conceptwhereas ​the concepts are explicitly defined ​and related to each other as in a taxonomy.

 +A [[:​gellish_english_dictionary|Gellish taxonomic dictionary]],​ such as the dictionary of Formal English, is an electronic '​smart'​ dictionary that is also a taxonomy and an ontology. This means that it contains definitions of concepts, each of which is identified by a unique identifier (UID) and can be referenced by one or more '​names'​ (terms, including synonyms, abbreviations and codes) and includes relations between concepts, among others subtype-supertype relations. The vocabulary of the formal language, being the names of concepts, are mainly ordinary natural language terms, many of them can also be found in ordinary English dictionaries. All definitions satisfy the [[:​proper_definition_of_a_concept|rules for proper definitions]] of concepts in Gellish. This means among others that every concept has a textual definition that refers to its supertype concept(s), and it also means that they have at least one explicit relation with its supertype concept. Thus together the concepts form a consistent subtype-supertype hierarchy of concepts or taxonomy. The [[:​gellish|Gellish Modeling Methodology]] provides guidelines for the extension of the taxonomic dictionary and for the creation of domain taxonomic dictionaries or just vocabularies in other languages. Such extensions or modifications may lead to separate [[:​proper_definition_of_a_concept|domain dictionaries]] for specialized application areas.

-When searching for kinds of relations for expressing information users (and supporting systems) should be aware that the phrases that denote the kinds of relations have a logical structure. The following patters can be recognized and should help finding the proper kinds of relations: 
-  * **- is a -** Information about individual things is typically expressed as relations between two individual things. Such relations are typically denoted by phrases that start with 'is a', 'has a' or 'has as', followed by the kind of role that one of the objects plays in the relation. For example, the phrases: is a friend of, has as friend. Software that support searching for such phrases should thus enable to search for a combination such words and should display alos the subtypes of found kinds of relations. 
-  * **- can be -** Knowledge about kinds of things is typically expressed as relations between two kinds of things. Such relations are typically denoted by phrases that start with 'can be a', 'can have a' or 'can have as', followed a kind of role and terminating with '​a'​. Natural language expressions of knowledge typically also start with '​a'​. For example: 'a pump can have as part a bearing'​. In the formalized language we ignore the first '​a',​ whereas we include the second '​a'​ as part of the phrase. Thus the formalized expression becomes: 
-^pump^can have as part a^bearing^ 
-  * Unordered List Item  
-An essential section (domain) of definitions in the taxonomic dictionary are the definitions of kinds of relations (also called relation types). Kinds of relations are typically denoted by '​phrases';​ thus they have phrases as names. Those phrases can be used in Gellish for making formalized expressions close to natural language. For example a composition relation has as name (is denoted by the phrase) 'is a part of', which phrase can be used in a Gellish expression such as: A is a part of B. It can also be denoted by its inverse phrase 'has as part'. This phrase can be used to express the inverse: B has as part A. Note that Gellish dictionary does not provide a definition of the separate words, such as is, a, part and of, but it gives a definition of the whole phrase, because the whole phrase represents a concept: a way of being related. ​ 
-The definitions of the standard kinds of relations of the Gellish languages is given in the base ontology section of the Gellish taxonomic dictionary. The kinds of relations currently have '​names'​ and '​Gellish phrases'​ in English and in Dutch (Nederlands) and some in German and French. That base ontology section also contains definitions (and names) of the kinds of the roles that are played by objects in relations of those kinds and it contains definitions of the kinds of things that can play such roles. The definitions of kinds of relations also satisfy the [[:​proper_definition_of_a_concept|rules for proper definitions]] of concepts in Gellish and thus form a consistent subtype-supertype hierarchy of kinds of relations. As all concepts in the dictionary, including the kinds of relations, roles and other kinds of things, are arranged in a subtype-supertype hierarchy of concepts, the Gellish dictionary is also a taxonomy. The collection expressions that form the base ontology in the dictionary composes the top of that subtype-supertype hierarchy of concepts. All other concepts in the dictionary are subtypes of those generic concepts. The data in the Gellish dictionary are stored in a [[:​gellish_table|Gellish database]] or file in Gellish Expression Format. The Gellish Expression Format is defined in the document 'The Gellish syntax and contextual facts'​.

 +===== 3. Kinds of relations =====
  
-The Gellish taxonomic dictionary defines concepts by expressing computer interpretable facts about the concepts. The prime expressions have the form of specialization relations or qualification relations. The facts are grouped in collections of facts that define domain specific subsets of the dictionary. In the current Gellish dictionary collections of facts can be distinguished about the following domains: 
  
 +The most important concepts in the Gellish taxonomic dictionary are kinds of relations. They determine the semantic expression power of the language. Each kind of relation is identified by a UID and is denoted by a name, which may be a short expression, such as 'being manager of an organization'​. Such a name is accompanied by a base phrase, such as 'is a manager of' and an inverse phrase, such as 'has as manager. A separate relation denotes which kind of thing should play the first role in the relation (in this example the role '​manager'​ and the role player '​person'​) and which kind or thing should play the second role (the role '​managed'​ and the role player '​organization'​). A base phrase requires that the player of the first role is located at the left hand of the phrase according to the normal English grammar and the player of the second role is at its right hand side. For an inverse phrase this is the other way around.  ​
  
-    ​* Generic concepts as required to define the Gellish grammar (especially ​the kinds of relations)+When searching for kinds of relations for expressing information users (and supporting systems) should be aware that kinds of relations are typically denoted in expressions by '​phrases';​ thus kinds of relations have phrases as their '​names'​. The phrases that denote the kinds of relations obey to a logical pattern. The following patterns can be recognized and should be helpful in searching for the proper kinds of relations:​ 
 +  * **- is a / has a -** Information about individual things is typically expressed as relations between two individual things. Such relations are typically denoted by phrases that conform to a particular pattern. Typically the phrases start with 'is a' or can be denoted by their inverse phrases that typically start with 'has a' or 'has as'. Such words are typically followed by the kind of role that is played by one of the objects in the relation. Typically such phrases do not terminate with '​a'​. For example, the phrases: 'is a friend of' and 'has as friend'​ both conform to that pattern. Software that support searching for such phrases should thus enable to search for a combination such words and should display also the subtypes of found kinds of relations. 
 +  * **- can be / can have -** Knowledge about kinds of things usually expresses possibilities,​ thus they express what can be the case. This is typically expressed as relations between two kinds of things. Such relations are typically denoted by phrases that start with 'can be' or 'can have', followed a kind of role and terminating with '​a'​. Natural language expressions of knowledge typically also start with '​a'​. For example: 'a pump can have as part a bearing'​. In the formalized language we ignore the first '​a',​ whereas we include the second '​a'​ as part of the phrase that denotes the standard kind of relation. Thus the formalized expression and its inverse becomes: 
 + 
 +^Name of left hand object^Name of kind of relation^Name of right hand object^ 
 +|pump|can have as part a|bearing| 
 +|bearing|can be a part of a|pump| 
 + 
 +  * **- shall be / shall have -** Requirements about what shall be the case (in a particular applicability context) for things of specific kinds are subtype of possibilities. Such requirements are typically expressed as phrases that start with 'shall be' or 'shall have' and are further similar to the possibilities. 
 +  * **- is by definition / has by definition -** Kinds of relations about what is by definition the case for things of particular kinds are subtypes of requirements. It is not only possible, and required but also necessarily the case. Phrases that denote such relations typically start with 'is by definition' ​ or 'has by definition'​ and are further similar to the possibilities. 
 +  * **- is ... a / has ... a -** Classification relations and other relations between individual things and kinds of things are typically denoted by phrases that start with '​is'​ or '​has',​ followed by a kind of role and typically terminating with '​a'​. For example, Rotterdam 'is classified as a' city and My car 'has as part a' turbo (in which 'My car' denotes an individual thing and '​turbo'​ denotes a kind of thing). 
 + 
 +All those kinds of relations are defined in the taxonomic dictionary. The phrases can be used in Gellish for making formalized expressions close to natural language. Note that Gellish dictionary does not provide definitions of the separate words, such as //is//, //a//, //part// and //of//, but it gives definitions of the whole phrases, because the whole phrases represent kind of relation concepts: ways of being related.  
 +The definitions of the standard kinds of relations of the Gellish languages is given in the base ontology section of the Gellish taxonomic dictionary. The kinds of relations currently have '​names'​ and '​Gellish phrases'​ in English and in Dutch (Nederlands) and some in German and French. That base ontology section also contains definitions (and names) of the kinds of the roles that are played by objects in relations of those kinds and it contains definitions of the kinds of things that can play such roles. The definitions of kinds of relations also satisfy the [[:​proper_definition_of_a_concept|rules for proper definitions]] of concepts in Gellish and thus form a consistent subtype-supertype hierarchy of kinds of relations. As all concepts in the dictionary, including the kinds of relations, roles and other kinds of things, are arranged in a subtype-supertype hierarchy of concepts, the Gellish dictionary is also a taxonomy. The collection of expressions that form the base ontology in the dictionary composes the top of that subtype-supertype hierarchy of concepts. All other concepts in the dictionary are subtypes of those generic concepts. The data in the Gellish dictionary are stored in a [[:​gellish_table|Gellish database]] or collection of files in Gellish Expression Format. For further information about that format see [[gellish_expression_format|the Gellish Expression Format]] and its definition in the document 'The Gellish syntax and contextual facts'​.

 +===== 4. Overview of the dictionary content ===== 
 + 
 + 
 +The Gellish taxonomic dictionary defines concepts by expressing computer interpretable expressions of ideas about the concepts. The prime expressions have the form of specialization relations or qualification relations. The expressions are grouped in collections of expressions that define domain related subsets of the dictionary. In the current Gellish dictionary collections of expressions can be distinguished about the following domains:

-The fact that the Gellish dictionary ​of Formal English satisfies these rules means that the Gellish Dictionary itself defines the Gellish Formal English language. In Gellish Formal English those relation types have names and synonyms that consist of standardized phrases. For example: the phrase 'is a part of' can be used to express the fact that A is a part of Bwhereas the phrase 'can have as part a' can be used to express ​the knowledge that a whole of a particular ​kind can have as part a component ​of a particular kindFor example, ​the fact that a pump can have a bearing ​is expressed in Gellish Formal English as:  +
