2 CML 2010 DUBROVNIK We offer an experimental support of the developed formal model of Argument Based Syntax. In this paper, we further developed the argument-based model of syntactic operations that is argued to represent the key to basic mental representations. The binding problem arises when the same noun occupies either a Subject or an Object position. The cat chases the mouse The mouse chases the cat The results of our experiments confirmed that semantic relations between the images in conceptual nets influence syntactic computation. We use the absence of of Accusative Case marker in Bulgarian and its rather free word order, and we show how the syntactic structure of ambiguous sentences is interpreted by means of other cognitive mechanisms.

3 CML 2010 DUBROVNIK by the (formal) semantic system (Hauser et al., 2002). Introduction Language Semantic system Following one of the widely accepted linguistic theories, the key component of Faculty of Language is a computational system (narrow syntax) that generates internal representations and maps them into the conceptual-intentional interface

4 CML 2010 DUBROVNIK Language SYNTACTIC RULES ? Semantic knowledge COMPUTATION There is a consensus that the core property of FL is recursion, which is attributed to narrow syntax. The claim is that this computation is based on a primitive operation that takes already constructed objects to create a new object. This basic operation, calledMerge, provides a language of thought, an internal system to allow preexistent conceptual resources to construct expressions (Chomsky, 2006). Introduction

5 CML 2010 DUBROVNIK One step in this direction was provided in Slavova and Soschen (2007). Syntactic structures, presented in the traditional sense of Chomskyan theory (Bare Phrase Structures, XP-structures), were re-defined in terms of finite recursive binary trees. XP X X S : The boy likes the girl The boy/ NP V/ likes the girl NP/ The girl Specifier Head X Complement The study of syntactic recursion by mathematical means may provide valuable insights into the principles underlying the human language.

13 CML 2010 DUBROVNIK This maximal configuration corresponds to thematic roles agent, recipient, and theme (the arguments in a sentence). These schemes represent all possible configurations and relations between arguments in the human theta-role Semantic Space. Introduction

14 CML 2010 DUBROVNIK The difficulty of designing an appropriate experiment is that mental computation runs on a deep (pre-linguistic) level and cannot be captured on the lexical level by a standard experiment. EXPERIMENT 1 One possible way to extract some information about the primary mechanisms is to force the mental system to solve ambiguities on the lexical level and to analyze the systems response. Language Rules, Operators Semantic knowledge computation Introduction

15 CML 2010 DUBROVNIK EXPERIMENT 1 In Bulgarian, sentences of type: are ambiguous where the used verb allows a Recipient (to whom). SubjectVerbthe Object на the Z NB Bulgarian exhibits certain peculiarities that set it apart from other Slavic languages, such as elimination of Case marking and the development of a suffixed definite article. They assign two different meanings to Z - Recipient and Possessor: SubjectVerbthe Object to the Z SubjectVerbthe Object of the Z Introduction

21 CML 2010 DUBROVNIK SYNTACTIC PROCEDURE WITH SEMANTIC MERGE Semantic Merge (M) is modeled as binary operation, performed in sequential progression between concepts verb Y* X* Z* The result of M consists of a couple, in which each element obtains an image, representing the concept in the semantic context of the other member of the couple. For example, the image of the concept X* within the couple [X*V] is the image of X* as Subject, performing V. verb X* X Acts V

30 CML 2010 DUBROVNIK The general conclusion is that people very much construct the meaning of what has been said.

31 CML 2010 DUBROVNIK (SVO): децата прочетоха писмoто. The children have read the letter. (SOV): децата писмoто прочетоха. The children the letter have read. (OSV): писмoто децата прочетоха. The letter the children have read. (OVS): писмoто прочетоха децата. The letter have read the children. (VOS): прочетоха писмoто децата. Have read the letter the children. (VSO): прочетоха децата писмoто. Have read the children the letter. EXPERIMENT 2 Subject Verb Object (Bulgarian) Although the Bulgarian nouns are not marked for Case, the word order is rather free. Thus, in a Bulgarian the sentence The children have read the letter can be expressed as the following: the Noun 1Verb the Noun 2 The children have read the letter the Noun 1Verb the Noun 2

32 CML 2010 DUBROVNIK EXPERIMENT 2 Subject Verb Object (Bulgarian) The children have read the letter the Noun 1Verb the Noun 2 Although SVO is the basic WO, all permutations are possible; they are grammatically correct, even thought some are used mostly in poetry. According to the Institute of Bulgarian at the Bulgarian Academy of Sciences, this grammatical particularity of permutation is possible because of the agreement between Subject and Verb which clarifies the role of Object. But what If the Verb is in agreement with both nouns? s There exists in Bulgarian a particular grammatical operation (clitic doubling) that marks Object in cases of a reverse word order, as in: (OVS): Иван го поздрави Мария. Ivan him congratulated Maria Maria congratulated Ivan.

33 CML 2010 DUBROVNIK EXPERIMENT 2 Subject Verb Object (Bulgarian) Noun 1 Noun 2 Noun 1 Verb Noun 2 The clitic (го/ги) is obligatory only when the subject and the object are in the third person, and they are both either singular or plural. According to the Institute of Bulgarian at the Bulgarian Academy of Sciences, When the meaning is clear from the context, the clitic can be omitted. (OVS): Иван го поздрави Мария. Ivan him congratulated Maria Maria congratulated Ivan. го/ги (OVS):Ролите озвучиха артистите: (list). The roles sound-screened the artists: The artists (from the list) sound-screened the roles. for example:

34 CML 2010 DUBROVNIK EXPERIMENT 2 (Merge patterns) M (X*,V) = [X*,V] X* = X*V (Y) X* V (?O) Y* 1. M ( X*, Y*) = [ X*, Y*] 2. X Acts (?O) Y* = Object X* V Noun 1Noun 2 verb The first mental operator in this treatment is to merge nouns with V* Stage I : Merge Subject-Verb M (X*V*) = [X*, V] (?O) X* = X* Acts (?O) Y* X* Stage II : Merge Acting Subject with Object Y* [ X*, Y*] = Object X* V X* X* V Object Y*

35 CML 2010 DUBROVNIK EXPERIMENT 2 (Merge patterns) M (Y*,V) = [Y*,V] X* V (?O) Y* 1. M ( Y*, X*) = [ Y*, X*] 2. = Y Acts (?O) Y* = X*V (Y) X* = Object Y* V Stage I : Merge Subject-Verb M (Y*V*) = [Y*, V] (?O) Y* = Y* Acts (?O) Stage II : Merge Acting Subject with Object X* Y* Y* V Object X*

36 CML 2010 DUBROVNIK EXPERIMENT 2 (Merge patterns) X* M (X*,V) = [X*,V] X* = X*V (Y) X* V (?O) Y* 1. M ( X*, Y*) = [ X*, Y*] 2. = X*V (?O) Y* = Object X* V Y* M (Y*,V) = [Y*,V] Y* = Y*V (X) X* V (?O) Y* 1. M ( Y*, X*) = [ Y*, X*] 2. = Y*V (?O) X* = Object Y* V We assume that these operations are semantically supported by the meaning of the concepts X* and Y*. X* Y* IF THERE ARE NOT GRAMMATICAL MARKERS…

37 CML 2010 DUBROVNIK EXPERIMENT 2 (Bulgarian) In this case, either X or Y can appear as Object: We used Bulgarian sentences of type: Where V is in agreement with both X and Y. X(noun)VerbY(noun) Subject Verb Object X(noun) Verb Y(noun)

38 CML 2010 DUBROVNIK EXPERIMENT 2 (Bulgarian) The following folk verses that contain sentences of the above kind were used in our experiment:

(Quickly, please) The written translations of the test statements were stored in a database. We designed our experiment as a translation (from Bulgarian to French) task.

Thus, our subjects had to assign a fixed word order to their French translations, thus bringing out their interpretation of the same noun as either Subject or Object.

56 CML 2010 DUBROVNIK CONCLUSIONS Experimental evidence is provided in support of the argument-based model. The semantic role of entities (nouns) is primary in syntax. The analysis provided here is based on the assumption that the syntactic treatment includes a Merge operation between the images of the concepts. The obtained formal description of the stages of syntactic treatment explains the experimental results.
