"Syntactic" AC-unification [chapter]

Alexandre Boudet, Evelyne Contejean
Constraints in Computational Logics  
The rules for unification in a simple syntactic theory, using Kirchner's mutation [15, 16] do not terminate in the case of associativecommutative theories.  ...  This provides a new AC-unification algorithm which does not make an explicit use of the solving of linear Diophantine equations.  ...  Syntactic Theories and AC-Unification In this section we recall some basic concepts about syntactic theories and ACunification.  ...

Unification and Matching in Hierarchical Combinations of Syntactic Theories [chapter]

Serdar Erbatur, Deepak Kapur, Andrew M. Marshall, Paliath Narendran, Christophe Ringeissen
2015 Lecture Notes in Computer Science  
In this paper we show that the hierarchical combination approach applies successfully to some classes of syntactic theories, such as shallow theories since the required unification algorithms needed for  ...  We also consider the matching problem in syntactic extensions of a base theory.  ...  For instance the Associative-Commutative (AC) theory is syntactic, as well as the E AC theory introduced in [9] as a finitary unifying theory of distributive exponentiation.  ...

Syntactic Ergativity in Light Verb Complements

Balthasar Bickel, Johanna Nichols
2001 Proceedings of the annual meeting of the Berkeley Linguistics Society  
Example (21) illustrates this for Tsez: (21) a. eni-r [u« z--a magalu b--ac'-ru-li] b-iy-xo.  ...  Argument structure unification Unification of arg-structures results in clause union (complex predicate formation) and implies a single set of grammatical relations.  ...

Neural correlates of artificial syntactic structure classification

Christian Forkstam, Peter Hagoort, Guillen Fernandez, Martin Ingvar, Karl Magnus Petersson
2006 NeuroImage  
Part of the left inferior frontal region (BA 45) was specifically related to syntactic violations and showed no sensitivity to local substring familiarity.  ...  In this study, we explored the outcome of this acquisition mechanism, and to this end, we investigated the neural correlates of artificial syntactic classification using event-related functional magnetic  ...  NG items might be attributed to the development of automatic aspects of syntactic integration (unification). Moreover, the opposite contrast of comparing classifications of NG vs.  ...

Creating a dependency syntactic treebank [chapter]

Kristiina Muhonen, Tanja Purtonen
2014 Linguistics Today  
Note that the unification only happens on the first level of sets, hence named top-level unification. Note also that the set operators in the prefixed set are ignored during unification.  ...  The same caveats as for Tag Unification apply. Chapter 17.  ...

Syntactic and semantic parsability

Geoffrey K. Pullum
1984 Proceedings of the 22nd annual meeting on Association for Computational Linguistics -  
Then I turn to a brief consideration of some syntactic proposals that employ more or less modest extensions of the power of context-free gr-mm-rs.  ...  An attempt is made to take into account the fact that parsing is scarcely ever thought about with reference to syntax alone; semantic ulterior motives always underly the assignment of a syntactic structure  ...  Unification Krannaars.  ...

On the syntactic category of Akan compounds

Clement Kwamina Insaidoo Appah
2015 Acta Linguistica Hungarica  
I show that compounding in Akan is blind to the syntactic category of the constituents. Thus, notwithstanding the syntactic category of the constituents the Akan compound is invariably nominal.  ...  This paper, therefore, provides evidence of holistic properties of morphological constructions in the form of the syntactic category of Akan compounds.  ...  The As Copestake (1993, 227) observes, "[t]he effect of default unification is that incompatible values for attributes are ignored, rather than causing unification failure".Acta Linguistica Hungarica  ...

Syntactic Theory: A Formal Introduction

Ivan A. Sag, Thomas Wasow
2000 Computational Linguistics  
A standard method for doing this is called unification.  ...  It is at this level that the real effect of unification is seen.  ...  In these examples, Pat, though a syntactic argument of seem and expect, is semantically an argument only of be on time.  ...

Word meaning, sentence meaning, and syntactic meaning [chapter]

Laura A. Michaelis
2003 Cognitive Linguistics Research  
Under this view, sentences have meaning, but the syntactic structures which sentences instantiate do not.  ...  Syntactic structures have correspondingly been seen only as providing instructions for the assembly of the concepts expressed by words.  ...  As Jackendoff (1997) has recently observed, the current consensus embraces unification rather than movement as the primary syntactic operation.  ...

A unification-based approach to morpho-syntactic parsing of agglutinative and other (highly) inflectional languages

Gábor Prószéky, Balázs Kis
1999 Proceedings of the 37th annual meeting of the Association for Computational Linguistics on Computational Linguistics -  
This paper introduces a new approach to morpho-syntactic analysis through Humor 99 (High-speed Unification Mo.rphology), a reversible and unification-based morphological analyzer which has already been  ...  Example 6 shows how a meta-dictionary can be drawn up to handle the above structure. 12 Example 6 [% indicates the starting state; $ indicates ending (or ac- cepting) states] START : % PREFIX  ...  This step (1) may reflect the internal hierarchy of symbols within the phrase, (2) sometimes includes actual unification of feature structures.  ...

Machine learning of syntactic parse trees for search and classification of text

Boris Galitsky
2013 Engineering applications of artificial intelligence  
We analyze semantic features of such similarity measure and compare it with semantics of traditional anti-unification of terms.  ...  Generalization of syntactic parse tree as a syntactic similarity measure is defined as the set of maximum common subtrees and performed at a level of paragraphs, sentences, phrases and individual words  ...  Hence we can refer to the syntactic tree generalization as the operation of anti-unification of syntactic trees.  ...

Generalised syntactic pattern recognition as a unifying approach in image analysis [chapter]

Mark Venguerov, Pádraig Cunningham
1998 Lecture Notes in Computer Science  
Finally, we note that at this level of generalisation, all three main approaches to pattern recognition (structural, statistical and syntactic) can be merged into one powerful method.  ...  In this paper we analyse theoretical foundations of syntactic pattern recognition and its relationships with mathematical linguistics, structural pattern recognition, and statistical pattern recognition  ...  Alternatively, a relation can be specified as a (multi@ace) predicate. Graph grammars are usually specified using extensional representation of relations.  ...
