Subject: Q: Lexical representations in Optimality Theory A question on lexical representations in Optimality Theory I am posting a query on behalf of my colleagues. 1.1 How OT Began. Introduction to Optimality Theory.....7 3. Sometimes there are different types of lines between constraints: solid line between constraints – represents a, dashed line between constraints – represents a non-crucial ranking, I’m not going to make this distinction in any tableaux, but you should be aware of the difference. Constraints that refer to a markedness hierarchy must be freely rankable and mention a contiguous range of the hierarchy, including the most marked element. One major problem is the phonological interference. phonology optimality-theory. The constraint list, sorted by disharmony (= ranking value + noise): Optimality Theory (Cambridge Textbooks in Linguistics series) by Rene Kager. Parallelism: Best-satisfaction of the constraints hierarchy is computed over the whole hierarchy and the whole candidate set. This chapter presents an overview of Optimality Theory (OT) as applied to phonology. The lack of restrictions on URs is a property called. Following H. Simon’s notion of satisficing, the authors have proposed a family of algorithms based on a simple psychological mechanism: one-reason decision making.”  ↩, We’re going to be discussing what’s sometimes called, Optimality Theory (Prince & Smolensky 1993). If constraint A is ranked above constraint B, we say that A. It has often been noted that phonotactic principles appear to be GRADIENT: Pick the output: EVAL(input, candidates, ℋ), This can be written as a single line: EVAL(/ab/, GEN(/ab/), ℋ). Differences in grammars reflect different rankings of the universal constraint set, CON. The mechanism of candidate generation is universal. However, if these theories are not vigorous as indeed they might have proved to be in reality, Prince and Smolensky submitted that one must entertain or consider one of these two conclusions below: The latter appears a more viable conclusion judging from expert opinion (see McCarthy and Prince 1993; Oyebade 1997; 1998). T & S look to Optimality Theory (OT) for the core principles that inform this learning strategy, and in this book they evaluate their proposed model, Robust Interpretive Parsing/Constraint Demotion (RIP/CDA), both for accuracy and computational efficiency, through a series of computer simulations and by a set of formal proofs. Important to note: although each language has the same ranking of constraints for every part of the language, we usually cannot discover a single strict total order of constraints. Examples of how to use “optimality” in a sentence from the Cambridge Dictionary Labs We are here to answer your questions. There are three basic components of the theory: Generator takes an input, generates the list of possible outputs, or candidates, Constraint component provides the criteria, in the form of ranked violable constraints, used to decide between candidates, Evaluator chooses the optimal candidate based on the constraints, this candidate is the output. The best approach for ranking constraints is to put the constraints into a tableau in a random order and then reason from there about the ranking. And this makes it possible for the generative phonologists to capture different phonological processes within this format. Optimality Theory: Constraint Interaction in Generative Grammar: Prince, Alan, Smolensky, Paul: Amazon.sg: Books The second strand of evidence emanates from the fact that since the late 1980s, evidence from syntactic analysis had shown that rule operated derivational grammars were already on their way out because constraint based grammars seem to have greater explanatory force. It means therefore, that the central thrust of linguistic investigation, would be to focus on a system that can be used to explain or analyse inputs, according to Prince and Smolensky, in terms of ‘the possible structural descriptions of rules – and to define the operations available for transforming inputs – the possible structural changes of rules’ (cited in Omachonu, 91). Violations are a penalty score: fewer violations is better. There are three basic components of the theory. “Don’t end a word with a voiced obstruent,” or deviating from URs, e.g. Constraints penalize marked structures in SRs, e.g. Optimality theory confronts these issues directly, designing its basic architecture to deal with them. Here, phonotactic constraints become the present in any grammar. Fear of Optimization. There are only two relevant constraints: faithfulness to voicing and a markedness constraint requiring agreement in voicing (F:Voi and M:Agree(Voi)). Hence there is undoubtedly no variety of OT which would accept all the constraints in our list as being simultaneously viable as part of one single theory.

Constraint re-ranking captures cross-linguistic variation and typology. (4). When such a violation of constraints occur, the* is used to show the number of times of any violation. In many cases, an actual utterance violates one or more of these constraints, so a sense of well-formedness applies to that utterance which violates the least number or least important constraints. First, it does away with the rule-formation of generative phonology and enthroned the function Gen which generates for any input a large space of candidate analysis. Optimality in the Lexicon. […] I hear the voices and I read the front page and I know the speculation but I’m the decider and I decide what is best. The innovation of Optimality Theory (OT) is to view grammars as a set of ranked violable constraints. We considered only four candidates from the candidate set of /ab/. If A ranks above B, and B ranks above C, then A ranks above C. When two constraints have conflicting requirements, satisfaction of the higher ranked constraint takes priority (no exceptions!). Before now, what existed as the most viable theoretical model was the generative phonology (with its subsequent modifications), which relies a great deal on phonological rules. Not all candidates can be shown; not all constraints are shown, either. This is not only peculiar to Nigerians alone. Candidates have an input portion (UR) and an output portion (SR), and nothing else. USC Graduate Phonology ✳︎ Fall 2019 ✳︎ Smith, Optimality Theory: rankings, GEN, CON, and EVAL, I say I listen to all voices but mine’s the final decision. On the basis of this conviction, scholars like Prince and Smolensky argue that any serious theory of phonology must be committed to Universal Grammar which means that it must rely heavily on the well-formedness constraints. The fleeing Ephramites were asked to pronounce the word ‘shibboleth’ as a test word for distinguishing them from the Gileadites. Pros and Cons Optimality Theory Language is a system of conflicting forces The scope of OT is to explain a widerange of linguistic phenomena including. Thus, phonemic substitution is a major challenge or problem area for the second language learner. 100% (1/1) Smolensky, Paul . OT models grammars as systems that provide mappings from inputs to outputs; typically, the inputs are conceived of as underlying representations, and the outputs as their surface realizations. OT differs from other approaches to phonological analysis, such as autosegmental phonology and linear phonology (SPE), which typically use rules rather than constraints. ABSTRACT From the early stage of Optimality Theory … But ʔ is only permitted before a stressed vowel. GEN(/ab/) = {[ab], [a], [b], [ba], [ ], [ta], [at], [ae], [diii], …}, The property that GEN can generate any conceivable output candidate for some input is called, A markedness constraint can be treated as a function from a candidate output to a positive integer (the number of. Optimality Theory has transformed the field of linguistics more than almost any other development of the past half-century, and Prince and Smolensky started it all.” John J. McCarthy, University of Massachusetts, Amherst "OT does not need to permanently influence linguistic theory: it … Although much of the interest in OT has been associated with its use in phonology (the area to which OT was first applied), the theory is also applicable to other subfields of linguistics (e.g. Constraints are universal but each language may … This is one of the most influential textbooks on conventional OT. “Which of these two cities has a higher population?”, and the cues are things like “Does this city have a soccer team?” However, the mechanisms are very similar to OT. Optimality Theory is a general model of how grammars are structured. Thinking about Optimality. Optimality theory (frequently abbreviated OT) is a linguistic model proposing that the observed forms of language arise from the interaction between conflicting constraints. Ilorin: University of Ilorin Press, 1992. Part of language acquisition can then be described as the process of adjusting the ranking of these constraints. The focus of explanatory action is elsewhere. 1. Optimality theory came as a child of necessity due to the flaws of the previous phonological models. 1 Introduction ... results only hold for a constraint-list representation of the grammar and not neces-sarily for other representations (we provide an alternative, efficient, representation below). In the tableau below, candidate b. isn’t the worst on any constraint, but it’s never the best either. The function that selects the winner from the set of candidates. "[Optimality Theory] holds that all languages have a set of constraints which produce the basic phonological and grammatical patterns of that particular language. Thus, the goal of optimality theory is to develop and or examine thoroughly the way that representational well-formedness determines the assignment of grammatical structure. Optimality Theory 101: Constraints > Rules. Building on Tesar (), these conditions are derived in two steps.First, idempotency is shown to follow from a general formal condition on the faithfulness constraints.

Optimality theory : constraint interaction in generative grammar. ), the same ranking is used for all inputs in a language, constraints as violation-counting functions, as a slogan: “take the best, ignore the rest”. Nsuk Texts in General Linguistics Vol 1. The decisions they’re interested in aren’t phonological, e.g. Keywords: optimality theory, computational complexity, generation problem 1. This change has been marked by the development of several theoretical frameworks both linearly and nonlinearly. 10. (13) NASAL Vowels are nasalized before a nasal consonant. Let’s make a tableau for the Dutch example from the last handout. Optimality Theory and Morphology Zheng Xu* National University of Singapore Abstract This article introduces Realization Optimality Theory, a novel and promising morphological framework which adopts the formalism of Optimality Theory and encodes the morphological realization rules of, for example, Aronoff (1994) as ranked violable constraints. In the 1990s, phonological investigation reached one of the most fascinating and challenging stages as phonologists began to chart a new direction for phonological theory. Literary Space and the Print Media in Northern Nigeria: A Study of Literature and Journalism, Les Difficultés Phonètiques Des Fracisants Gworog, Shades of Meaning Associated with Personal Names and Naming in Igala, The Poetic Experience of Zhulkifli Muhammad: An Analytical Literary Study, Phonology itself simply does not have much content, is mostly “periphery” rather than “core”, is just a technique for data compression, by the inevitable idiosyncrasies of history and lexicon; or. Redefine these constraints so they aren’t ambiguous, make tableaux for both inputs, and find a ranking that works. Violability: Constraints are violable; but violation is minimal. (n factorial) is the product of all positive integers less than or equal to n. Although there are 120 rankings of 5 constraints, chances are that many of these rankings will generate the same input-output mappings, so there are likely fewer than 120 different sets of input-output mappings. The Reassurance. As Spencer cited in Ogbuehi points out, “the phonology of a second language will almost always receive some imprint from the phonology of the mother tongue” (30) One can easily identify people from different ethnic groups when they speak English in Nigeria. I argue that the controversy results from conceptual pitfalls. Why Optimality Theory has nothing to do with connectionism. It introduces both the central idea and general architecture of OT. 1.6 Constraint Activity. Alignment Constraints in Optimality Theory:Two Examples Daniel Teuber 1.Introduction 1.1.Alignment and Optimality Theory This paper looks at the linguistic phenomenon of alignment,in which languages show a preference for certain linguistic features to be aligned with other linguistic features.The goal of this paper is to present to the Foundational Issues and Theory--Comparisons:. Generalized Alignment (McCarthy & Prince 1993), which introduced alignment constraints. 1.3 The Nature of Constraints in OT. This article argues that both language-specific conflation and universal markedness relations can be expressed in Optimality Theory. Is there a formal list of such constraints, or are there too many to list/not enough information about them? If we repeat this for different inputs, we get a set of mappings generated by the ranking. Optimaliteitstheorie (OT) is een in de vroege jaren negentig door de Amerikaanse taalkundigen Paul Smolensky, Alan Prince en John McCarthy ontwikkeld model van taalkundige structuur. For instance, the use of the Anaptictic vowel is common among the three major tribes in Nigeria. Optimality theory : constraint interaction in generative grammar. There is no serial derivation. While English is a stressed timed language, our indigenous languages are syllable timed which makes use of tonality to show voice quality. OT models grammars as systems that provide mappings from inputs to outputs; typically, the inputs are conceived of as underlying representations, and the outputs as their surface realizations. To create such a grammar in Praat, choose Create NoCoda grammar from the Optimality Theory submenu of the New menu. However, as McCarthy (2010) and Pruitt (2010) show, another kind of … Inclusiveness: The constraint hierarchy evaluates a set of candidate analyses that are admitted by very general considerations of structural well-formedness. Optimality Theory in Phonology: A Reader is a collection of readings on this important new theory by leading figures in the field, including a lengthy excerpt from Prince and Smolensky’s never-before-published Optimality Theory: Constraint Interaction in Generative Grammar. Optimality Theory (frequently abbreviated OT; second word normally capitalized by convention) is a linguistic model proposing that the observed forms of language arise from the interaction between conflicting constraints. Constraints in OFT models are a means to distinguish between possible and impossible behaviours. Keep in mind that nearly every imagineable revision to OT assumptions has been pursued at some point in the past 20+ years, and much of the research in OT has been devoted to answering the question “What are the constraints?”. Oyebade, F. ‘Phonology II’. To find just the winners, if you have n constraints…, Find the candidates that tie for being “best” (fewest violations) on the top-ranked constraint C. Because of strict domination, none of the lower-ranked constraints matter – just the constraint currently under consideration. Take the candidates that have the fewest violations and discard the rest. They never directly reward candidates. Three important constraint families are explored (Faithfulness, Alignment, and Markedness). Introduction In 1991, Alan Prince and Paul Smolensky began presenting their work on a new approach to language. What happens if the constraint “Don’t end a word with a voiced obstruent” takes priority over “Don’t devoice”? Optimality theory, particularly optimal foraging theory (OFT), has spurned controversy over decades. The optimal candidate is the output of the grammar. Introduction to Optimality Theory Optimality Theory (OT) was introduced as a theory of language phenomena in the early 90’s of the previous century. 1. below faithfulness constraints. An OTGrammar object will then appear in the list of objects. The ranking of constraints accounts for the segmental inventory of a language, its phonotactics, and its alternations. When we construct a ranking for a particular language, we describe only the rankings that are. For instance, Nigerians and Britons will pronounce the following words with unequal stress and with different stress shift: Another problem area among some Nigerian speakers of English is that of the infusion of phonemic sound segments where they are not required. In contrast, many models of rational inference treat the mind as a Laplacean Demon, equipped with unlimited time, knowledge, and computational might. Ze wordt beschouwd als de opvolger van de in 1990 door Géraldine Legendre, Yoshiro Miyata en Smolensky voorgestelde Harmonische Grammatica.De Optimaliteitstheorie heeft aanvankelijk vooral ingang … Stop!). The empirical focus is sonority-driven stress in Nganasan and Kiriwina. (12) Structure of Optimality Theory: a. CON: a universal set of constraints, b. a language specific “ranking” of those constraints. These are GEN, which generates all candidate sets to be evaluated, CON, which stands for constraints and EVAL, which does the evaluation of candidates (cited in Oyebade 1998:175), One of the most famous illustrations of this framework is presented by McCarthy and Prince (1993) in their technical report on generalized alignment, which sought to show how OT can provide a principled treatment of the ways in which the edges of prosodic or morphological constituents align with one another. If you click Edit, an OTGrammarEditor will show up, containing: 1. McCarthy, J. and Prince, A. (We’ll dicuss why dashed vs. solid lines is an unhelpful and insufficient distinction on the next handout.). The relevant constraints are shown below: There is a violation of the open syllable rule in (a) above in the word /unfaithful/ as we find each syllable having a closed ended feature rather than being open-ended. A  B/C – D to be worth pursuing, a theory which defines the class of possible predicates CAD (structural description) must be there, and another interesting theory which defines the class of possible operations A  B (Structural Changes) must also be put in place. This paper establishes tight sufficient conditions for idempotency in (classical) Optimality Theory. The pointing finger, exclamation marks, and shading are predictable from the asterisks, but they are helpful to the reader. (14) /hænd/ NAS ☞ [hæ˜nd] [hænd] *! 24.901 Phonological Constraints and Optimality Theory 1. Cambridge: Cambridge University Press. Either A ranks above B, or B ranks above A. List of Abbreviations. This book is the final version of the widely-circulated 1993 Technical Report that introduces a conception of grammar in which well-formedness is defined as optimality with respect to a ranked set of universal constraints. Is there a candidate for /ab/ that we didn’t consider, which could’ve beaten [b]? Optimality Theory and acquisition.....10 4. 1.7 Differences Between Languages. There are no intermediate forms as there are for SPE-style rules. Thus, in ‘unfaithful’, we can have the violations represented as ***! share | improve this question | follow | edited Apr 23 '13 at 13:51. arjan. A relatively new linguistic theory is Optimality Theory. First, in the early days of generative phonology, it was found that the burden of the explanatory adequacy of most phonological events does not reside in the feature changing rules but with the phonotactic constraints that languages onbserve. The first component, Gen, generates the list of … New York: Harper and Row, 1968. In either case, the constraints should be clearly defined and their violations should be displayed in tableaux. These constraints are used in Optimality Theory, such as NOCODA: 'syllables end with a vowel'. Optimality theory assumes that these components are universal. For the remaining candidates, {[ab], [a], [b], []}check the first constraint: *ab: assign one violation for every [a] followed by [b]. OPTIMALITY THEORY: ISSUES AND CONSTRAINTS. These constraints are used in Optimality Theory, such as NOCODA: 'syllables end with a vowel'. Optimality Theory. Prince & Smolensky (1993) introduced Optimality Theory and constraints for OT. Okay, so here’s a crash course in Optimality Theory (or OT) for any confused linguistics or curious parties out there. To summarise the modus operandi of OT, it may be plausible to argue that these principles together with the basic assumptions have given birth to the three fundamental functions in OT. Optimality Theory - History It is a linguistic model proposing that the observed forms of language arise from the interaction between conflicting constraints. Introduction to Optimality Theory 7 2. What does output does the grammar generate for: First, generate a candidate set: GEN(/ab/) = {[ab], [a], [b], []}, EVAL(/ab/, {[ab], [a], [b], []}, ranking). As mentioned a few times above, different rankings will often produce the same mappings. (Nope), For the remaining candidates, {[a], [b], []},check the next constraint: *ab ≫, For the remaining candidates, {[a], [b]},check the next constraint: *ab ≫, There is a single remaining candidate. Chomsky, N. The Sound Patterns of English. A possibly helpful analogy: you can think of the constraint ranking as a hierarchy of authoritarian autocrats, each of whom defers to his superior and doesn’t care about the opinions of his underlings. An Introduction to Optimality Theory. At it’s base, OT is essentially just an alternative way to view phonology. Some examples pulled/elaborated from McCarthy's "A thematic guide to Optimality Theory", p. 13, without correct IPA: (What I am elaborating is the necessary rankings that McCarthy leaves implicit in the discussion) n! Optimality also abandons the widely held view that constraints are language – specific statements of phonotactic truth. When candidates are rule out as optimal, an exclamation mark ‘!’ is placed in the cell showing the number of violations. According to Omachonu, Optimality operates on five fundamental principles. The tableau is not a full calculation, but rather an illustrative device, like a derivation in rule-based analyses. Ranked Violable In Conflict In other words Constraints are universal but cross . This is achieved by showing the derivational sequence or path of an item in its journey from the underlying level to the surface level. Final version of the widely circulated 1993 Technical Report that was the seminal work in Optimality Theory, never before available in book format. One can use this theory to describe the English syllable structure. Optimality theory, to an extent, appears to be one of the relatively new theories of phonology.

The authors give what is now considered a classic analysis of Tagalog language using Um-infixation. 1,610 11 11 silver badges 22 22 bronze badges. OT is a theory of constraint interaction in grammar, which aims to solve a couple of problems that have confronted generative phonological theory since its earliest days. (The choice of segment is made by other constraints.) It also addresses some frequently asked questions about this theory and offers suggestions for further reading. The Connectionism Connection, and other Computation--based Comparisons. This, in the opinion of experts, is because constraint based grammars have brought the focus of the linguists and researchers alike back to the issue of identifying the properties of Universal Grammar. Therefore, what marks individual grammars, in this model, is the order in which these constraints apply. Ranking: The constraints of Con are ranked on a language – particular basis; the notion of minimal violation is defined in terms of this ranking. Optimality Theory - is grammar about rules or constraints? Given the architecture of generative phonology, which distinguishes between underlying lexical forms and surface forms, and given the Constraints only assign violations. Constraints evaluate SRs or similarity between URs and SRs. (Nope), There are no more constraints to check. Consequently, “the Hebrew word ‘shibboleth’, meaning ‘ears of corn’, is now used to denote any particularity in speech of a geographical area.” (Ogbuehi 31). A lot of factors account for these problems especially in the case of the Nigerian child trying to learn English. 4:01. Another good beginning example is past tense. OT in General: Robot Ethics OT in Phonology: Final Devoicing Constraints *[+voiced]# Stops at the word end should not be [+voiced] IDENT [voiced] Corresponding input and output sounds should … Nsukka: Magnet Business Enterprises, 2001. Optimality theory or OT is a linguistic model proposed by the linguists Alan Prince and Paul Smolensky in 1993, and expanded by John J. McCarthy and Alan Prince in 1993. These constraints are assumed to be universal, and the difference between child phonology and adult phonology, and between the grammars of different languages, now lies in differences in the ranking of the constraints. Treue-Beschränkungen: Don’t change! The three basic components of the theory are Gen, Con and Eval. asked Apr 22 '13 at 13:11. Constraints have different ranking modes and they are violable in OT, the output of the grammar need not be, and almost never is, perfect in the sense that it obeys all the constraints. One way to think of it: apply all possible operations to the input, any number of times (deletion, insertion, feature changing, maybe changing order). The mechanism for choosing the optimal candidate is universal. A faithfulness constraint can be treated as a function from an input-output pair to a positive integer (the number of violations): The best way to write constraints is to describe the function explicitly, starting with “Assign one violation for every…”, and give it a descriptive name (often written in small caps and/or with a *). We hope that it will serve as a helpful methodological tool in evaluating the validity of general assertions about OT. shading – shows that a cell is not relevant, either because the winner has already been chosen, or because that candidate has already been ruled out. /input/ – sometimes this is in the upper lefthand corner, [output] candidates – which are usually lettered for reference. *CC = assign one violation for every sequence of two consonants in the output.. From the first lines of the paper’s abstract: “Humans and animals make inferences about the world under limited time and knowledge. KEY WORDS: optimality theory, constraint, phonological disorders, assessment, treatment LSHSS O ptimality theory is a formal linguistic framework for describing grammatical systems that was first developed in the early 1990s (McCarthy & Prince, 1994, 1995; Prince & Smolensky, 1993). McCarthy and Prince showed that the optimal output can be achieved for each variant by invoking two constraints, first a syllabl structure constraint, and the then an ‘edge-most’ or ‘align’ constraint, which deals with how far a linguistic entity like the Um-infixation can be from the edge of some unit (like the prosodic word or stem). NativLang 24,383 views. Optimality Theory (OT) is a linguistic model originally proposed by the linguists Alan Prince and Paul Smolensky in 1993. This is somehow due to the fact that most indigenous languages have open-ended syllable structure unlike English that is both open and closed ended. Correspondence Theory (McCarthy & Prince 1995), which revised faithfulness constraints.

OT differs from other approaches to phonological analysis, such as autosegmental phonology and linear phonology (SPE), which typically use rules rather than constraints. ABSTRACT From the early stage of Optimality Theory … But ʔ is only permitted before a stressed vowel. GEN(/ab/) = {[ab], [a], [b], [ba], [ ], [ta], [at], [ae], [diii], …}, The property that GEN can generate any conceivable output candidate for some input is called, A markedness constraint can be treated as a function from a candidate output to a positive integer (the number of. Optimality Theory has transformed the field of linguistics more than almost any other development of the past half-century, and Prince and Smolensky started it all.” John J. McCarthy, University of Massachusetts, Amherst "OT does not need to permanently influence linguistic theory: it … Although much of the interest in OT has been associated with its use in phonology (the area to which OT was first applied), the theory is also applicable to other subfields of linguistics (e.g. Constraints are universal but each language may … This is one of the most influential textbooks on conventional OT. “Which of these two cities has a higher population?”, and the cues are things like “Does this city have a soccer team?” However, the mechanisms are very similar to OT. Optimality Theory is a general model of how grammars are structured. Thinking about Optimality. Optimality theory (frequently abbreviated OT) is a linguistic model proposing that the observed forms of language arise from the interaction between conflicting constraints. Ilorin: University of Ilorin Press, 1992. Part of language acquisition can then be described as the process of adjusting the ranking of these constraints. The focus of explanatory action is elsewhere. 1. Optimality theory came as a child of necessity due to the flaws of the previous phonological models. 1 Introduction ... results only hold for a constraint-list representation of the grammar and not neces-sarily for other representations (we provide an alternative, efficient, representation below). In the tableau below, candidate b. isn’t the worst on any constraint, but it’s never the best either. The function that selects the winner from the set of candidates. "[Optimality Theory] holds that all languages have a set of constraints which produce the basic phonological and grammatical patterns of that particular language. Thus, the goal of optimality theory is to develop and or examine thoroughly the way that representational well-formedness determines the assignment of grammatical structure. Optimality Theory 101: Constraints > Rules. Building on Tesar (), these conditions are derived in two steps.First, idempotency is shown to follow from a general formal condition on the faithfulness constraints.
