==== a ==== == antecedent == An antecedent "comes before". In NetWeaver an antecedent is a node that supplies data or some evaluation up to a higher level node (a [[#dependent|dependent]] node). == argument == An argument is an expression that is used to evaluate the value of a [[#data link|data link]]. Arguments come in two flavors: [[.nodes:crisp argument|crisp]] and [[.nodes:fuzzy argument|fuzzy]]. == argument list == An argument list is collection of arguments. Some [[#proxy|proxies]] and all [[#data link|data links]] use argument lists. All arguments are owned by a data link. Arguments in a proxy's argument list are owned by its data link, so the same argument can be efficiently used in multiple proxies. This also means any change made in an argument is global: the change affects every place the argument is used. ==== b ==== == boss == synonym for [[#topic|topic]] ==== c ==== == child node == A child node is a node that is attached directly to and beneath the subject node (its [[#parent node|parent node]]). The child node "hangs" from its [[#parent node|parent node]]. In this relationship there is always only one parent and can be multiple children, if supported by the [[#parent node|parent node]]. == circular reasoning == A self-referential answer to a question. See [[#circular reasoning|circular reasoning]]. NetWeaver does not allow connections that would result in circular reasoning. ==== d ==== == data link == A data link is a [[#topic|topic]] type for bringing data into the knowledge base. Data links come in two flavors: [[.nodes:simple data link|simple]] and [[.nodes:calculated data link|calculated]]. Simple data links bring elemental data directly into the knowledge base. Calculated data links process data through an equation represented by a network of nodes. Either flavor of data link can be compared to an [[#argument|argument]] from its [[#argument list|argument list]] to calculate a trueness level or (if allowed in the situation) used directly in calculations. == dependency network == A dependency network is a formal logical representation of how system states at one level of a conceptual model are affected by, or dependent on, other antecedent states. Also known as a "goal". [[netweaver:concepts:dependency network|more...]] == dependent == A dependent is a node that receives data or some evaluation from another node (an [[#antecedent|antecedent]] node). == domain expert == synonym for [[#subject matter expert|subject matter expert]] ==== f ==== == flexible documentation == With NetWeaver2 comes a new documentation system: * Documents can be attached to any node. * No naming restrictions. * Supports full suite of rich text formatting. * Embedded images. * Live hyperlinks. * Importing from or exporting to many standard formats. == fuzzy logic == Fuzzy logic is an analysis or control methodology that determines degree of set membership (trueness) rather than "is" or "is not" (true or false). Think "shades of gray" rather than "black and white". [[netweaver:concepts:fuzzy logic|more...]] Fuzzy logic is used extensively through NetWeaver. ==== g ==== == goal == synonym for [[#dependency network|dependency network]] ==== h ==== == hint == The hint is a brief description of the topic. In the case of data links it should be the question to be asked to elicit the data. In earlier versions (pre 2) of NetWeaver the "comment" documentation field filled this role. == hyperlink == {{http://netweaver.rules-of-thumb.com/images/common_3.png }}A hyperlink is a connection to external information. It is represented as a typical URL and can refer to a web-based or file-based document. When a hyperlink button is pressed or an internal jump to hyperlink command is run, NetWeaver attempts to launch your default browser to the hyperlink. ==== i ==== == influence == In NetWeaver influence is short hand for "influence of missing data". NetWeaver has built in capability to calculate the relative influence missing data has on outcomes. This is extremely important for prioritizing efficient and rational querying and data collection. [[netweaver:concepts:influence calculations|more...]] ==== k === == knowledge base == A knowledge base is the repository for NetWeaver [[#topic|topics]] and relationships. [[netweaver:concepts:knowledge base|more...]] == knowledge engineering == Knowledge engineering is the process of eliciting knowledge, representing the knowledge in some codified way, and verifying the validity of that knowledge representation. ==== n ==== == network == A network is a system of connected nodes such as a [[#dependency network|dependency network]] or the equation in a [[netweaver:nodes:calculated data link|calculated data link]]. A network is more than representative. It is also a conduit for messages. NetWeaver uses networks to communicate things like data needs and evaluation messages between nodes. == node == A node is any NetWeaver object that can be connected to another NetWeaver object. ==== p ==== == parent node == A parent node is the node that is above and directly attached to the subject node. The nodes that "hang" just below a parent node are called its [[#child node|child nodes]]. == problem domain == A problem domain is a virtual space within which all pertinent data and fuzzy membership functions are contained that describe our current understanding of the problem domain. == proxy == A proxy is a representative or a "stand-in" for something else. In NetWeaver proxies are nodes that represent a [[#topic|topic node]] in a [[#network|network]]. The following nodes are proxy nodes: * [[netweaver:nodes:data link proxy|data link proxy]] * [[netweaver:nodes:goal proxy|goal proxy]] * [[netweaver:nodes:switch|switch]] * [[netweaver:nodes:fuzzy curve|fuzzy curve]] ==== s ==== == subject matter expert == A subject matter expert is someone who has a proficient understanding of the issues of the problem or knowledge (the [[#problem domain|problem domain]]) that is being captured into a knowledge base. ==== t ==== == topic == A topic is a high level node. Topics have also been referred to as "boss" nodes due to their relationship to [[#proxy|proxy nodes]]. Each topic has a unique proper name. Topics can be any of the following types: * {{http://netweaver.rules-of-thumb.com/images/common_84.png }}[[netweaver:nodes:goal group|goal group]] * {{http://netweaver.rules-of-thumb.com/images/common_85.png }}[[netweaver:nodes:goal|goal]] (aka [[netweaver:concepts:dependency_network|dependency network]]) * {{http://netweaver.rules-of-thumb.com/images/common_86.png }}[[netweaver:nodes:calculated data link|calculated data link]] * {{http://netweaver.rules-of-thumb.com/images/common_87.png }}[[netweaver:nodes:simple data link|simple data link]] ==== w ==== == weight == Weight is an numeric attribute of all nodes, however it is only used in certain special situations (see the documentation for individual nodes). If a node's weight is not explicitly assigned it defaults to 1.
