Information chaining
Information chaining is the simultaneous use of more than one date in a logical connection. Each information chain describes the structured connection of information that z. B. was created, procured or saved in individual steps. Linking these individual information elements creates information chains. Information elements can be data as content , for example .
Information can be created or obtained and stored in individual information elements. This is about the meaning and benefits of concatenations . Such concatenations are described by the data for the content and the metadata for the concatenation, which help save multiple copying. Linking these information elements creates information chains. This concatenation can be linear, so that long chains result. An example is a conventional printing unit. A typical case for linked information is a book which contains textual information continuously on stapled or bound pages. Indexes such as the table of contents concatenate the information.
The chaining can also be done by indexing on several levels, so that by following the index structure in different aspects different linear or still networked partial chains are created. The index itself initially creates an index structure with a possibly no longer linear multi-dimensional linkage via the indices. The use of different media with the index structures produces a hypertext structure with the various media no longer being linearly linked .
Memory performance
Human memory is associative . We combine small information elements and create complex knowledge structures . Mostly remember we are in the information in an associative manner. When reading or saving information, an attempt is made to combine the information with information that is already available. The order in which a person connects one idea with another depends on the context in which he is currently working.
Sequential structures, like conventional books, do not reflect the way in which humans represent knowledge in their brain, namely as a complex network. When reading, complex relationships must be restored with the help of indices. Knowledge is inevitably lost in this type of information exchange.
Relationships between information objects
The purpose of an informal presentation is to inform a user about a certain issue. For this purpose, many individual information units, for example media objects, are generally required, which have to be brought into a specific relationship with one another. This connection can be established via relationships, dependencies or conditions that are defined between the information objects. These relationships are known as chains.
A linear chain structure is, for example, a one-dimensional structure without branches. A planar chain structure is, for example, a two-dimensional structure without branches. A branched chain structure is, for example, a text that contains pointers to other texts and thus defines branches.
In a graph of a multimedia relationship network of information, the edges represent these links. However, the semantics of the edges are not uniform. Rather, there are different types of relationships.
Modal relationships
For the storage of information, there is a sudden change in storage technologies and their temporary use for certain purposes. Associated with this are the corresponding changes in the presentation of the information from these storage media. Storage technology, i.e. the merging of storage technology and storage processes, defines a modal chain of information that can be changed with the selection of storage media without changing the information content.
Multimedia relationships
The representation of information through media allows special views of the existing information stock, whereby the viewer uses selected media. As a rule, the technique of storage remains invariant to the formatting for presentation in individual media.
Spatial Relationships
If information is referred to by an index in several dimensions, a spatial or, more generally, multidimensional linkage arises, which initially remains without a corresponding technical presentation. For the presentation, a one-dimensional, i.e. linear linkage, for example for transmission, or a two-dimensional, i.e. planar linkage, for example for a display or a printout, or a three-dimensional, i.e. spatial linkage, for example using a spatial projection method, must then be selected.
Temporal Relationships
If information is retrieved from an inventory and linked in the presentation, a complex temporal relationship of the information elements is created that is defined with this retrieval and generated from the retrieval process. The validity of this temporal chain is limited to the life of the selected presentation.
Mnemonic relationships
When information passes from a presentation to a memory, new individual chains arise that are tied to the individual. The teaching is concerned with the task of providing optimal mnemonic linkages to train and ensure that the information provided to keep to the schedule. Many multimedia presentation systems ignore elementary didactic concepts as long as they are aimed exclusively at short-term effects. So far there is no testable and generally valid reference to the connection between optimization of multimedia-based emotional response to information and the sustainability of the mnemonic availability of the same information.
Authoring systems
By hypertext and hypermedia is possible to generate non-linear information linkages that the way of human knowledge representation much better reproduce than traditional linear information concatenation.
Authoring systems and publication systems also enable the creation of network-like and thus natural information structures.
