Oettinger(1966)
In an early observation on the difficulties of getting computers to processnatural language,Anthony Oettinger used the example above to illustrate
howwetendtointerpretsentencesbasedonanexpectedstructureandwhen
wearriveataproblematic interpretation,weareable togobackand try touse a different structure. This process brings to light the importance ofrecognizingtheunderlyingstructureofsentencesinordertomakesenseofthem.Ifwekeepthinkingthat thestructureof thesecondexpressionis thesameas the first in theexample,wewilldefinitelymiss something. (Forahelpfulanalysis,seeFigure8.9,onpage122.)InChapter7,wemovedfromthegeneralcategoriesoftraditionalgrammar
to more specific methods of describing the structure of phrases andsentences.Whenweconcentrateonthestructureandorderingofcomponentswithin a sentence, we are studying the syntax of a language. The word“syntax” comes originally from Greek and literally means “a puttingtogether” or “arrangement.” In earlier approaches, therewas an attempt toproduceanaccuratedescriptionof thesequenceorordering“arrangement”ofelementsinthelinearstructureofthesentence.Inmorerecentattemptstoanalyze structure, there has been a greater focus on the underlying rulesystemthatweusetoproduceor“generate”sentences.
SyntacticrulesWhenwesetout toprovideananalysisof thesyntaxofa language,we try toadheretothe“allandonly”criterion.Thismeansthatouranalysismustaccountfor all the grammatically correct phrases and sentences and only thosegrammatically correct phrases and sentences in whatever language we areanalyzing. In other words, if we write rules for the creation of well-formedstructures,wehavetocheckthatthoserules,whenappliedlogically,won’talsoleadtoill-formedstructures.
Forexample,wemightsayinformallythat,inEnglish,weputapreposition(near) before a noun (London) to form a prepositional phrase (near London).Thiswilldescribealargenumberofphrases,butdoesitdescribeall(andonly)the prepositional phrases inEnglish?Note that, ifweuse this as a rule of thegrammartocreatestructuresinvolvingaprepositionandanoun,wewillendupproducingphrases like*near tree or*withdog. These don’t seem to bewell-formedEnglishstructures, sowemark themwithanasterisk*, indicating thattheyareungrammatical.
We clearly need to bemore careful in forming the rule that underlies thestructureofprepositionalphrasesinEnglish.Wemighthavemoresuccesswitharulestatingthatweputaprepositionbeforeanounphrase(notjustanoun).InChapter7,wesawthatanounphrasecanconsistofapropernoun(London),apronoun(me)orthecombinationofanarticle(a,the)withanoun(tree,dog),sothat therevisedrulecanbeused toproduce thesewell-formedstructures:nearLondon,withme,nearatree,withthedog.
AGenerativeGrammar
When we have an effective rule such as “a prepositional phrase in Englishconsists of a preposition followed by a noun phrase,” we can imagine anextremely large number of English phrases that could be produced using thisrule. In fact, the potential number is unlimited. This reflects another goal ofsyntacticanalysis,which is tohaveasmallandfinite (i.e. limited)setof rulesthatwillbecapableofproducingalargeandpotentiallyinfinite(i.e.unlimited)numberofwell-formedstructures.Thissmallandfinitesetofrulesissometimesdescribed as a generative grammar because it can be used to “generate” orproducesentencestructuresandnotjustdescribethem.
This typeofgrammarshouldalsobecapableof revealing thebasisof twootherphenomena: first,howsomesuperficiallydifferentphrasesandsentences
are closely related and, second, how some superficially similar phrases and
sentencesareinfactdifferent.
DeepandSurfaceStructureOur intuitions tell us that theremust be some underlying similarity involvingthese two superficially different sentences:Charlie broke thewindow andThewindow was broken by Charlie. In traditional grammar, the first is called anactive sentence, focusing on what Charlie did, and the second is a passivesentence, focusing on The window and what happened to it. The distinctionbetween them is a difference in their surface structure, that is, the differentsyntactic forms they have as individual English sentences. However, thissuperficialdifferenceinformdisguisesthefactthatthetwosentencesarecloselyrelated,evenidentical,atalesssuperficiallevel.
Thisother“underlying”level,wherethebasiccomponents(NounPhrase+Verb+NounPhrase)sharedbythetwosentencescanberepresented, iscalledtheir deep structure. The deep structure is an abstract level of structuralorganization inwhichall the elementsdetermining structural interpretation arerepresented.Thatsamedeepstructurecanbe thesourceofmanyothersurfacestructures such as ItwasCharliewho broke thewindow andWas thewindowbrokenbyCharlie?. In short, thegrammarmustbe capableof showinghowasingleunderlyingabstractrepresentationcanbecomedifferentsurfacestructures.
StructuralAmbiguity
Let’s say we have two distinct deep structures. One expresses the idea that“Annie had an umbrella and she bumped into a man with it.” The otherexpressestheideathat“Anniebumpedintoamanandthemanhappenedtobecarryinganumbrella.”Now,thesetwodifferentversionsofeventscanactually
beexpressedinthesamesurfacestructureform:Anniebumpedintoamanwithanumbrella.Thissentenceprovidesanexampleofstructuralambiguity.Ithastwodistinctunderlyinginterpretationsthathavetoberepresenteddifferentlyindeepstructure.NotethatthisisnotthetypeofambiguitythatweexperienceinhearingTheirchildhasgrownanother foot,which illustrates lexicalambiguitymainlybecause theword foot hasmore than onemeaning. (SeeTaskH, page120,forfurtheranalysis.)
The comedian Groucho Marx knew how to have fun with structuralambiguity.InthefilmAnimalCrackers,hefirstsaysIonceshotanelephantinmypajamas,thenfollowsitwithHowhegotintomypajamasI’llneverknow.Inthenon-funnyinterpretation,partoftheunderlyingstructureofthefirstsentencecouldbesomethinglike:“Ishotanelephant(whileIwas)inmypajamas.”Intheother(ho,ho)interpretation,partoftheunderlyingstructurewouldbesomethinglike: “I shot anelephant (whichwas) inmypajamas.”Thereare twodifferentunderlying structures with the same surface structure, revealed by syntacticanalysis.
SyntacticAnalysisIn syntactic analysis we use some conventional abbreviations for the parts ofspeechidentifiedinChapter7.ExamplesareN(=noun),Art(=article),Adj(=adjective)andV(=verb).Wealsouseabbreviationsforphrases,suchasNP(=nounphrase)andVP(=verbphrase).InEnglish,theverbphrase(VP)consistsof the verb (V) plus the following noun phrase (NP).We can take the simplesentence from Table 7.3 (page 98) and label the constituents using thesecategories,asinFigure8.1.
Figure8.1
Figure8.1presentsastaticanalysisofasinglesentence.Wewouldliketobeabletorepresentthesamesyntacticinformationinamoredynamicformat.One
way of presenting the concept “consists of” is with an arrow (→), alsointerpretedas “rewrites as.”The following rule states that anounphrase (NP)
suchasthedogconsistsoforrewritesas(→)anarticle(the)andanoun(dog).Thissimpleformulais theunderlyingstructureofmillionsofdifferentEnglishphrases.
NP→ArtN
However,itisnottheonlyformanounphrasecantake.Wewanttobeableto include another constituent (Adj) in the rule so that it is good for not onlyphraseslikethedog,butalsothebigdog.Thisconstituentisoptionalinanounphrase,soweuseroundbracketstoindicatethatAdjisanoptionalconstituent,asshownhere:
NP→Art(Adj)N
Anothercommonsymbolisintheformofcurlybrackets{}.Theseindicatethat only one of the elements enclosed within the curly brackets must beselected.Wehavealreadyseen,inFigure7.3,onpage96,thatanounphrasecan
also contain a pronoun (it), or a proper noun (John). Using the abbreviations“Pro” (for pronoun) and “PN” (for proper noun), we canwrite three separaterules,asshownontheleft,butitismoresuccincttowriteonerule,ontheright,usingcurlybrackets.
NP→Art(Adj)N
NP→Pro NP→{Art(Adj)N,Pro,PN}
NP→PN
PhraseStructureRulesWhatwehavestartedtocreateisasetofsyntacticrulescalledphrasestructurerules.Asthenamesuggests,theserulesstatethatthestructureofaphraseofaspecifictypewillconsistofoneormoreconstituentsinaparticularorder.
The first rule in the following set of simple (and necessarily incomplete)phrasestructurerulescapturesaverygeneralruleofEnglishsentencestructure:“a sentence (S) rewrites as a noun phrase (NP) and a verb phrase (VP).”Thesecond rule states that “a noun phrase rewrites as either an article plus anoptionaladjectiveplusanoun,orapronoun,orapropernoun.”Inthethirdrule,averbphraserewritesasaverbplusanounphrase.
S→NPVP
NP→{Art(Adj)N,Pro,PN}
VP→VNP
LexicalRules
Phrasestructure rulesgenerate structures. Inorder to turn thosestructures intorecognizableEnglish,wealsoneed lexicalrules that specifywhichwordscanbeusedwhenwerewriteconstituentssuchasPN.Thefirstruleinthefollowingset states that “a proper noun rewrites as John orMary.” (It is a very smallworld.)
PN→{John,Mary} Art→{a,the}
N→{girl,dog,boy} Adj→{big,small}
V→{followed,helped,saw} Pro→{it,you}
We can rely on these rules to generate the grammatical sentences shownbelowin(1)–(6),butnottheungrammaticalsentencesshownin(7)–(12).
(1)Adogfollowedtheboy. (7)*Dogfollowedboy.
(2)Yousawit. (8)*Youitsaw.
(3)Johnsawthebigdog. (9)*JohnMarysmalldog
(4)ItfollowedMary. (10)*FollowedMarythedogbig.
(5)Thesmallboyhelpedyou. (11)*Thehelpedyouboy
(6)MaryhelpedJohn. (12*MaryJohnhelped.
TreeDiagramsOne of the bestways to create a visual representation of underlying syntacticstructureisthroughtreediagrams.Wecanusethesymbolsintroducedearliertolabelpartsofthetreewhenwecreatearepresentationofhoweachpartfitsinto
theunderlyingstructureofphrases.The information inaphrase structure rule,

Figure8.2
Althoughthiskindof“tree,”withits“branches,”ontheright,seemstogrowdownrather than up, it functions ratherwell as a diagram representing all thegrammatical information found in the other analysis on the left. It also showsveryexplicitly that there aredifferent levels in the analysis.That is, there is alevelofanalysisatwhichaconstituentsuchasNPisrepresentedandadifferent,lower,levelatwhichaconstituentsuchasNisrepresented.
