Sense of Wonder,

weblog written in English by David Cherry, the truth is that looks great in both presentation and content, that ultimately becomes important. Fundamental problems of the theory of computation, programming languages, knowledge representation ... are, broadly speaking, some of the topics covered so far, supplemented by promising data such as found in the right column under "Worth reading documents, selection of relevant documents on various subjects.

By the way, and since we mentioned the statistical system, is very curious and expressive, very "semantic", the identification Nedstat makes

of the sections that divides the information provided, namely: "Here and Now," "When" "Where," "How," "With what "... Certainly it is a form of classification
• of
faceted organization of information reminiscent of the five major facets or fundamental
• colonnade Classification ("Colon Classification") of Ranghanatan
: Personality
• , Matter, Energy
,
• Space and Time . These allow you to group the information in "semantic fields", determined by a number of similarities and common characteristics. Ranganathan
considered the world as a set of entities
• variables, decomposable into the views or
facets, which are the standard terms, used to classify subjects enumerated above:
• Personality: The first qualifying order, the primary focus of each subject and therefore the most active order. Matter: aspects, properties, qualities, material elements.
• Power: actions, procedures, techniques. Space: place where something happened.

Time: all reality is viewed from a location in time.

faceted systems are based in the analysis and decomposition of the materials into their component parts, and the union of these parts according to the document being rendered. Therefore involve a process of analysis and synthesis, which takes into account the individuality of each document and allows a high degree of autonomy in making decisions when classified. We

the following advantages of faceted classification:

Divisions facets are original means to channel the materials and knowledge. Allow explain concepts more accurately than enumerative systems (those listed, listed, listing all the materials with linear nature, dividing the subjects into classes of different hierarchical levels, falling in specificity), from a number of smaller items. The facets have high combining ability, based on few initial elements. faceted systems lend themselves well to automation, since a subject can be located from each facet with which is was described, affecting in this way in certain aspects of the postcoordinación (post-coordinate indexing languages \u200b\u200bin terms of description are used freely without priori relationship between them, establishing this relationship at the time of recovery of the document).

have a great capacity to integrate new concepts. You can make changes at a facet of a given area without affecting the others. However : faceted systems have a structure for each particular subject, with defined hierarchical levels less than the equivalent in nature enumerative classifications. resulting notations are often complicated and difficult to memorize, to be adapted specifically to each particular document. descriptions responsibility always rests on the competence of the classification, while the enumerative systems it has settled on the boards. In any case, the faceted classification system developed by Ranganathan, was an important theoretical advance of decisive influence on subsequent classification systems and combinatorial nature of modern thesauri.
