General similarity search of quantifiable resources is possible on the Web, if these are represented in standardized way. As standardized data structure for representation of quantifiable resources a "Domain Vector" (DV) is proposed, which contains a feature vector for representation of the quantitative data and a URI called "Domain Space Identifier" (DSI) as Vector Space Identifier which identifies the containing metric space which is called "Domain Space" (DS). The DS definition explains the meaning of every dimension (number) of the (feature vector in the) Domain Vector. DVs of the same DS are directly comparable using a given metric. At this similarities of the resources' data are linked (mapped) to spatial similarities of the feature vectors. So similarity search is possible by calculating distances: resources are the more similar, the smaller the distance between the feature vectors of the representing DVs is. This numeric search could be efficiently combined with conventional word based search. There are many arguments for this approach, e.g. many numeric data are stored in separated databases in the hidden web. The proposed DV structure gives also motivation to pack such numeric data in a globally accessible and interchangeable form. So it could also help to make hidden (numeric) data from the deep web accessible for all people. The approach allows to handle and search numeric data to very different topics or DSIs with the same software.For up to date details see this http URL
