1)    hypertext
·    Hypertext, at its most basic level, is a DBMS that lets you connect screens of information using associative links. At its most        sophisticated level, hypertext is a software environment for collaborative work, communication, and knowledge acquisition.        Hypertext products mimic the brain's ability to store and retrieve information by referential links for quick and intuitive access.

·    "Hypertext" is a term created by visionary Ted Nelson to describe non-linear writing in which you follow associative paths          through a world of textual documents. The most common use of hypertext these days is found in the links on World Wide           Web pages.

2)    link
·    Definition: A hypertext link on a web site other than your own that points to your web site. Inbound links are an important          part of web site marketing as they can deliver targeted visitors directly from another web site, and can help to improve the          ranking position of your web site on engines that use link popularity as a part of their algorithm.

·    6: computing) an instruction that connects one part of a
     program or an element on a list to another program or list.

3) lexi
     The lexia is a block of hypertext which is connected to other lexiae through links, which comment upon each other (some            might say, dialogue with each other). Roland Barthes’ definition ( S/Z ) provides us with an understanding that this is the basic      building block of the hypertextual universe: It is the atom, the letter, the point of hypertext. It is viewed nonsequentially from        the perspective of the author, sequentially from the perspective of the reader, and is the embodiment of the poststructuralist        ideal: brief interconnected segments whose context is provided by the lexiae that surround it in three dimensions.

4) node
·    Conditional Probability Table (DSL_CPT): this node represents a discrete random variable with a set of states representing        the possible outcomes of the variable. The definition consist of one list of vectors of numbers, one vector for each                       combination of outcomes of the parents, each vector containing the conditional probability distribution over the outcomes of       the variable. This list of vectors is implemented by using a DSL_Dmatrix object. As an alternative, the probability distribution      of the node can be encoded as a NoisyMAX (DSL_NOISY_MAX)

·    Truth Table (DSL_TRUTHTABLE): this node represents a discrete deterministic variable with a set of states representing          the possible outcomes of the variable. The definition consists of one list of vectors of numbers, one vector for each                      combination of outcomes of the parents, each vector containing the state of the node for the given combination of parents.          The outcome of the node is represented in this vector by assigning 1 to the probability of that outcome and 0 to the                    probability of the rest of the outcomes.

5) interactivity

·    Interactivity is "a process whereby students are systematically encouraged to be active participants in their own learning. It is     achieved by teaching approaches that engage students in the construction of knowledge."
