Several of the techniques include the production of hierarchies and sorting of entries by various attributes. Some of this is carried out by the analyst, but some requires subjective assessments by domain experts. | Lecture 24 dialogue notations and design Today’s Lecture Today we will discuss about A dialogue Dialog notations Single-threaded dialog Multiple-threaded dialog Concurrent dialog The term “dialogue” From Merriam and Webster a : a conversation between two or more persons; also : a similar exchange between a person and something else (as a computer) The term “conversation”: a (1) : oral exchange of sentiments, observations, opinions, or ideas b : an exchange of ideas and opinions c : a discussion between representatives of parties to a conflict that is aimed at resolution A Dialogue could be Two parties or more (Let’s call them John and Mary) John and Mary talk about politics Goal: an exchange of ideas about something John and Mary talk about how to solve a problem.

Three Levels of Computer Language Semantic The meaning of the conversation in terms of its effect on the computer’s internal data structures and/or the external world. In human language, the meaning ascribed by the different participants to the conversation. Dialogue Notations and Design Dialogue Notations Diagrammatic state transition networks, JSD diagrams, flow charts Textual formal grammars, production rules, CSP Dialogue linked to the semantics of the system – what it does the presentation of the system – how it looks Formal descriptions can be analyzed for inconsistent actions for difficult to reverse actions for missing actions for potential miskeying | Lecture 24 dialogue notations and design Today’s Lecture Today we will discuss about A dialogue Dialog notations Single-threaded dialog Multiple-threaded dialog Concurrent dialog The term “dialogue” From Merriam and Webster a : a conversation between two or more persons; also : a similar exchange between a person and something else (as a computer) The term “conversation”: a (1) : oral exchange of sentiments, observations, opinions, or ideas b : an exchange of ideas and opinions c : a discussion between representatives of parties to a conflict that is aimed at resolution A Dialogue could be Two parties or more (Let’s call them John and Mary) John and Mary talk about politics Goal: an exchange of ideas about something John and Mary talk about how to solve a problem.
