Towards a machine-learning architecture for lexical functional grammar parsing
Data-driven grammar induction aims at producing wide-coverage grammars of human languages. Initial efforts in this field produced relatively shallow linguistic representations such as phrase-structure trees, which only encode constituent structure. Recent work on inducing deep grammars from …

A Lexical Functional Grammar Account of Spanish Weak Dative Pronominals
… or in a configuration where they are not lexically specified in the valency of the verb, the so-called non-selected datives. The analysis of the dative in ditransitive constructions is twofold. We claim that the distribution of the dative in such configurations has semantic and syntactic …

Using ChatGPT as a Tool to Acquire the Passive Voice in English
… of helping people learn English passive voice. Lexical Functional Grammar was mentioned and compared to transformational grammar. A survey was conducted, and the results indicated that ChatGPT is helpful for people, and they would rely on its answers. Every prompt in the thesis was generated …

An LFG approach to Modern Greek Relative Clauses
… relative clauses). Working in the framework of Lexical Functional Grammar, we present an overview of the most important properties of Modern Greek Relative Clauses focusing on the distribution of the gap and resumption strategies in these constructions. We propose an analysis of Relative Clauses …

Grammatical feature data-oriented parsing
… Parsing (DOP) are augmented with the functional representations of Lexical Functional Grammar (LFG). The result is a robust parsing model which generates linguistically informed output. However, difficulties arise in the accurate implementation of fragmentation and sampling in this …

A unification-based natural language interface to a database.
An implementation of a Lexical Functional Grammar (LFG) natural language front-end to a database is presented, and its capabilities demonstrated by reference to a set of queries used in the Chat-80 system. The potential of LFG for such applications is explored. Other grammars previously used for …

Exploiting multi-word units in statistical parsing and generation
… Multi-word units are phrases that are lexically, syntactically and/or semantically idiosyncratic in that they are to at least some degree non-compositional. If such units are identified prior to, or as part of, the parsing process their boundaries can be exploited as islands of …

An intelligent question: answering system for natural language
… Computational Linguistics theories, such as the Lexical-Functional Grammar (LFG) theory complemented with Artificial Intelligence representation and processing techniques. A prototype Question-Answering System has been developed. It takes Natural Language parsed interrogatives, produces the …

Treebank-based automatic acquisition of wide coverage, deep linguistic resources for Japanese
… of multilingual resources in the framework of Lexical-Functional Grammar (LFG). After introducing the basic framework of LFG in Chapter 2, I describe the core syntactic and morphological aspects of Japanese in Chapter 3: non-configurationality; the concept of "bunsetsu" r syntactic units and …

Treebank-based acquisition of Chinese LFG resources for parsing and generation
… to automatically acquire robust,wide-coverage Lexical-Functional Grammar (LFG) resources for Chinese parsing and generation, which is part of a larger project on the rapid construction of deep, large-scale, constraint-based, multilingual grammatical resources. I present an application-oriented …

Natural Arabic language text understanding
… of its rich computational, morphological and grammar rules. Among different representation techniques, Lexical Functional Grammar (LFG) theory is found to be best suited for this task because of its structural approach. LFG lays down a computational approach towards NLP, especially the …

Negation in Turaif Arabic: Not the last word.
… of negation in TA within the framework of Lexical Functional Grammar (LFG). The main focus of this study is on the syntax of sentential and constituent negation, negative coordination, and negative sensitive items. I additionally deal with issues related to neg raising predicates and …

Temporal and Aspectual auxiliaries in Maltese
… as they combine with one another and with lexical verbs and participles in periphrastic structures. The bleached semantics displayed by the forms to be discussed will be taken to be our primary identifier of an auxiliary status. Only one auxiliary expresses tense in the language, however a …

A novel dependency-based evaluation metric for machine translation
… and fluently will be given a low score if the lexical and syntactic choices it contains, even though perfectly legitimate, are not present in at least one of the references. Necessarily, this score would differ from a much more favourable human judgment that such a translation would receive. …
