Lingua Inglese 2 CInt AA 2009/<strong>10</strong>Dott.ssa Maria Ivana Lor<strong>en</strong>zettiImplications for a Semantic Theory• What is the relevance of the concept ofprototype for semantics?• Words have an inher<strong>en</strong>tly plastic meaning.• They can be used figuratively and theirmeaning can vary, but we can frequ<strong>en</strong>tly relyon the concept of prototype to account for astable common core which functions as apoint of departure for all the possiblecontextual interpretationsFrame Semantics• Concepts do not simply float around in the mind. On theone hand, there are relations betwe<strong>en</strong> words andcorresponding concepts described in structuralsemantics.• But concepts are organized in another way as well.Certain concepts “belong together”, because they areassociated in experi<strong>en</strong>ce. To use a classic example, aRESTAURANT is not merely a service institution, but hasassociated with it a number of concepts such asCUSTOMER, WAITER, ORDERING, EATING, BILL,which are related to RESTAURANT not by hyponymy,meronymy, antonymy or other structural semanticrelations. They are related to RESTAURANT by ordinaryhuman experi<strong>en</strong>ce<strong>Lecture</strong> <strong>15</strong> - <strong>12</strong>/<strong>05</strong>/<strong>20<strong>10</strong></strong> 16
Lingua Inglese 2 CInt AA 2009/<strong>10</strong>Dott.ssa Maria Ivana Lor<strong>en</strong>zettiWhat is a Frame?• Words are typically defined in terms of backgrounds ofexperi<strong>en</strong>ce or frames, which are highly structured• A frame id<strong>en</strong>tifies the characteristic features, attributesand functions of a giv<strong>en</strong> d<strong>en</strong>otatum, and it is built from<strong>en</strong>cyclopaedic knowledge• “A word’s meaning can be understood only withrefer<strong>en</strong>ce to a structured background of experi<strong>en</strong>ce,beliefs, or practices constituting a kind of conceptualprerequisite for understanding its meaning. Speakerscan be said to know the meaning of a word, only by firstunderstanding the background frames that motivate theconcept that the word <strong>en</strong>codes” (Fillmore and Atkins1992)The Semantics of Understanding• Meaning cannot be conceived indep<strong>en</strong>d<strong>en</strong>tly of the waywe conceptualise reality. Wh<strong>en</strong>ever we are <strong>en</strong>gaged in acommunicative interaction we do not talk by words inisolated atoms, but words are embedded in texts and arepart of larger wholes. Therefore, the meaning of lexicalitems can best be understood in terms of theircontribution to the process of interpreting a text• Frame semantics is meant as a model for the semanticsof understanding: the full and rich understanding that aspeaker int<strong>en</strong>ds to convey in a text and that a hearerconstructs for that text.<strong>Lecture</strong> <strong>15</strong> - <strong>12</strong>/<strong>05</strong>/<strong>20<strong>10</strong></strong> 17
Lingua Inglese 2 CInt AA 2009/<strong>10</strong>Dott.ssa Maria Ivana Lor<strong>en</strong>zettiThe Semantics of Understanding (2)• A speaker produces words and constructions in atext as tools for a particular activity, namely toconvey a particular message• The task of the hearer is to figure out the activitythose tools were int<strong>en</strong>ded for, i.e. to invoke thatunderstanding (what did the speaker mean by that?)• Words and constructions evoke a frame, areassociated to certain background knowledge, andthe hearer invokes that frame in order to makes<strong>en</strong>se of an utteranceFrames and Semantic Fields• Frame semantics shares significant properties withsemantic field theory• They both group together words that are associatedin experi<strong>en</strong>ce• Semantic field theory posits systems of syntagmaticand paradigmatic relations connecting members of aselected set of lexical items → words are defined inrelation to other words like pawns in the game ofchess<strong>Lecture</strong> <strong>15</strong> - <strong>12</strong>/<strong>05</strong>/<strong>20<strong>10</strong></strong> 18
Lingua Inglese 2 CInt AA 2009/<strong>10</strong>Dott.ssa Maria Ivana Lor<strong>en</strong>zettiFrames and Semantic Fields (2)• In frame semantic words are defined directlywith respect to the frame. The frame functionsas a link, as a mediator to guaranteeunderstandingWORDSactivateFRAMEevokesUNDERSTANDINGAn Example: Day Names• In semantic field theory we can say thatMONDAY, TUESDAY, WEDNESDAY etc.comprise a closed set of words related by asuccessor relation, which in this case definesa cycle.• These words are therefore interdefinable byvirtue of their position in the cycle, asestablished by their mutual relationships andby the “part of” relationship WEEK, whichnames the <strong>en</strong>tire cycle<strong>Lecture</strong> <strong>15</strong> - <strong>12</strong>/<strong>05</strong>/<strong>20<strong>10</strong></strong> 19
Lingua Inglese 2 CInt AA 2009/<strong>10</strong>Dott.ssa Maria Ivana Lor<strong>en</strong>zettiAn Example: Day Names (2)• A frame-based description of these terms would conc<strong>en</strong>trate onthe manner they fit into the system of cal<strong>en</strong>dric terms• What holds these words together is the fact that they areconstructed and motivated by a special schematization ofexperi<strong>en</strong>ce Natural cycle created by the appar<strong>en</strong>t daily travel of the sun The standard means of defining wh<strong>en</strong> one day <strong>en</strong>ds and anotherbeginsThe conv<strong>en</strong>tional cal<strong>en</strong>dric cycle of 7 daysThe practice of assigning differ<strong>en</strong>t portions of the weekly cycle towork and nonwork• The awar<strong>en</strong>ess of the particular organization of our physical andsocial world provides the conceptual background for a number ofnouns (week, day), their adjectival derivations, the individualweekday names, and other categories such as weekday, week<strong>en</strong>d,fortnight etc.Frame Semantics: An EncyclopaedicView of Meaning• Frame semantics involves an <strong>en</strong>cyclopaedicconception of meaning, and specifically it arguesthat meaning is not determined by linguisticproperties, but is strongly related to people’scollateral experi<strong>en</strong>ce. More specifically, in the framesemantics perspective "words repres<strong>en</strong>tcategorizations of experi<strong>en</strong>ce and each of thesecategories is underlain by a motivating situationoccurring against a background of knowledge andexperi<strong>en</strong>ce" (Fillmore 1982: 1<strong>12</strong>).<strong>Lecture</strong> <strong>15</strong> - <strong>12</strong>/<strong>05</strong>/<strong>20<strong>10</strong></strong> 20
Lingua Inglese 2 CInt AA 2009/<strong>10</strong>Dott.ssa Maria Ivana Lor<strong>en</strong>zettiFrame Semantics (4)• A number of important concepts figure into the FrameSemantics approach to linguistic description and analysis.One such concept is that of prototype, understood as a fairlylarge slice of the surrounding culture against which themeaning of a word is defined and understood. For example, tounderstand the meaning of the word breakfast, it is necessaryto understand the institutions and practices of the culture inwhich the category exists. In this case, it is necessary tounderstand the practice of eating three meals a day at moreor less fixed times and that the meal eat<strong>en</strong> in the early part ofthe day after a period of sleep has a special m<strong>en</strong>u.• Another important concept in frame semantics is that ofperspective, as exemplified in the slogan "meanings arerelativised to sc<strong>en</strong>es" (Fillmore 1977).The Commercial Transaction Frame<strong>Lecture</strong> <strong>15</strong> - <strong>12</strong>/<strong>05</strong>/<strong>20<strong>10</strong></strong> 21
