Understanding Discourse Analysis and Its Components
Discourse analysis focuses on linguistic units beyond single utterances, exploring the structure and coherence of spoken or written language. This analysis delves into defining discourse, providing examples, and discussing the criteria for qualifying a text as discourse. Through cohesion, coherence, intentionality, acceptability, informativeness, and situationality, discourse analysis reveals the intricacies of language communication.

Background to Discourse Up to this point of the book, we have focused primarily on language phenomena that operate at the word or sentence level. Of course, language does not normally consist of isolated, unrelated sentences, but instead of collocated, related groups of sentences. We refer to such a group of sentences as a discourse. Natural Language Processing (NLP) by Rahman Ali, Lect: QACC, UOP 3 5 October 2024
Discourse Definition Originally the word 'discourse' comes from Latin 'discursus' which denoted 'conversation, speech'. Definition 1: "Discourse: a continuous stretch (an unbroken sequence of utterences) of (especially spoken) language larger than a sentence, often constituting a coherent unit such as a sermon (religious speech), argument, joke, or narrative (occurrence of an act or event)" (Crystal 1992:25). Definition 2: According to Cook (1990:7) novels, as well as short conversations or groans might be equally rightfully named discourses. Definition 3: Discourse - The study of linguistic units larger than a single utterance (Juraffsky) Natural Language Processing (NLP) by Rahman Ali, Lect: QACC, UOP 4 5 October 2024
Example of Discourse Gracie: Oh yeah... And then Mr. and Mrs. Jones were having matrimonial trouble, and my brother was hired to watch Mrs. Jones. George: Well, I imagine she was a very attractive woman. Gracie: She was, and my brother watched her day and night for six months. George: Well, what happened? Gracie: She finally got a divorce. George: Mrs. Jones? Gracie: No, my brother's wife. (Juraffsky) Natural Language Processing (NLP) by Rahman Ali, Lect: QACC, UOP 5 5 October 2024
Criteria for Qualifying a Discourse Seven criteria which have to be fulfilled to qualify either a written or a spoken text as a discourse have been suggested by Beaugrande (1981). These include: Cohesion grammatical relationship between parts of a sentence essential for its interpretation; Coherence the order of statements relates one another by sense. Intentionality the message has to be conveyed deliberately and consciously; Acceptability indicates that the communicative product needs to be satisfactory in that the audience approves it; Informativeness some new information has to be included in the discourse; Situationality circumstances in which the remark is made are important; Intertextuality reference to the world outside the text or the interpreters' schemata; Natural Language Processing (NLP) by Rahman Ali, Lect: QACC, UOP 6 5 October 2024
Discourse Unit In TBMT, the unit for analysis is a discourse unit (DU) rather than a sentence. Definition of DU A DU is that part of the text which is between two successive discourse boundaries (DBs). Discourse Boundary DB, itself, is like a sentence boundary (e.g. '.') across which there are no anaphoric and/or cataphoric reference links. (M.A. Khan, 2004) Natural Language Processing (NLP) by Rahman Ali, Lect: QACC, UOP 7 5 October 2024
Types of Discourse Unit Mono-sentential Discourse If a discourse consist of only one sentence then it is called mono-sentential discourse or simple discourse. For example: [Be patient on what you have in your hand.] Poly-sentential Discourse If a discourse consist of more than one sentences then it is called poly- sentential discourse or complex/ compound discourse.

Types of Discourse Unit (Cont..) Example of poly-sentential discourse [Los Angeles A man who claims to be Angelina Jolie's former drug dealer says the star was high on cocaine when she took part in a TV interview back in 2000. According to Franklin Meyer, the 25-year-old actress visited him both before and after the interview with broadcaster Charlie Rose to buy cocaine. 'She'd taken coke,' he told Life & Style magazine. 'She did the show and then she came back over after. ] (The Daily News: 22 Oct, 2010) Natural Language Processing (NLP) by Rahman Ali, Lect: QACC, UOP 9 5 October 2024
What is Discourse Analysis??? Discourse analysis is the examination of spoken, signed or written language for any aspect of linguistic behavior. Sign language (also signed language) is a language which, instead of acoustically conveyed sound patterns, uses visually transmitted sign patterns (manual communication, body language) to convey meaning simultaneously combining hand shapes, orientation and movement of the hands, arms or body, and facial expressions to fluidly express a speaker's thoughts. Natural Language Processing (NLP) by Rahman Ali, Lect: QACC, UOP 10 5 October 2024
Discourse analysts A person performing discourse analysis is called discourse analyst. Natural Language Processing (NLP) by Rahman Ali, Lect: QACC, UOP 11 5 October 2024
Discourse Analyst/Discourse Analysis Focuses on?? Focus on any aspect of linguistic behavior: study of particular patterns of pronunciation, word choice, sentence structure, semantic representation, pragmatic analysis of how we organize speech encounters (and any combination of these in spoken, written and signed discourse). Natural Language Processing (NLP) by Rahman Ali, Lect: QACC, UOP 12 5 October 2024
From Where We Can Study a Discourse??? A wide array of linguistic texts are explored in the study of discourse. These might consist of: a conversation or a letter; a speech, a memo or a report; a broadcast, a newspaper article or an interview; a lesson, a consultation or a confrontational (argumentation) encounter; an advertisement, a flyer or a piece of gossip.

Discourse Analysis also Focuses on Cohesion Coherence References resolution Ellipsis resolution and Ambiguity resolution (will talk in comming lectures) Natural Language Processing (NLP) by Rahman Ali, Lect: QACC, UOP 14 5 October 2024
