Automatic Extraction of Definitions in Portuguese: A Rule-Based Approach [chapter]

Rosa Del Gaudio, António Branco
2007 Lecture Notes in Computer Science  
In this paper we present a rule-based system for automatic extraction of definitions from Portuguese texts.  ...  For each one of these domains and for each type of definition typology, evaluation results are presented. On average, we obtain 14% for precision, 86% for recall and 0.33 for F 2 score.  ...  Introduction The aim of this paper is to present a rule-based system for the automatic extraction of definitions from Portuguese texts, and the result of its evaluation against test data made of texts  ...

Jhih-Jie Chen, Chingyu Yang, Peichen Ho, Ming Chiao Tsai, Chia-Fang Ho, Kai-Wen Tuan, Chung-Ting Tsai, Wen-Bin Han, Jason Chang
2019 Proceedings of the 57th Annual Meeting of the Association for Computational Linguistics: System Demonstrations  
In our approach, grammar patterns, collocations, representative examples are extracted, aimed at providing rich lexical information for any target words.  ...  The method involves word sense disambiguation on target words, automatically parsing the sentences in a large-scale corpus, automatically generating grammar patterns, collocations, examples, and quizzes  ...  To explore the feasibility of identifying grammar patterns computationally, Mason (2004) conducted a limited experiment of automatic parsing based on COBUILD grammar patterns with reasonable success.  ...

Grammar Zoo: A corpus of experimental grammarware

Vadim Zaytsev
2015 Science of Computer Programming  
The Grammar Zoo displays the results of grammar hunting for big grammars of mainstream languages, as well as collecting grammars of smaller DSLs and extracting grammatical knowledge from other places.  ...  In this paper we describe composition of a corpus of grammars in a broad sense in order to enable reuse of knowledge accumulated in the field of grammarware engineering.  ...  The state of the art tools allow fully automatic grammar recovery to work based on a specification of the expected metalanguage [1] . • Analysers for investigating grammar properties, calculating grammar  ...

A Web-Based Self-Learning Grammar For Spoken Language Understanding

S. M. Biondi, V. Catania, R. Di Natale, A. R. Intilisano, D. Panno
2014 Zenodo  
In the SDS domain, the Spoken Language Understanding (SLU) Module classifies user utterances by means of a pre-definite conceptual knowledge.  ...  The proposed solution attempts to automatically recognize the meaning associated with an utterance by using the PANKOW (Pattern based Annotation through Knowledge On the Web) method at runtime.  ...  Most SLU modules are based on a Context Free Grammar (CFG) that provides the definition of the meaning of each word and the set of utterances related to it.  ...

PAPEL: A Dictionary-Based Lexical Ontology for Portuguese [chapter]

Hugo Gonçalo Oliveira, Diana Santos, Paulo Gomes, Nuno Seco
2008 Lecture Notes in Computer Science  
This paper describes a project aimed at creating a lexical ontology extracted (semi) automatically from a large Portuguese general dictionary.  ...  Although using machine readable dictionaries to extract semantic information is not new, we believe this is the first attempt for the Portuguese language.  ...  Acknowledgments We would like to thank the group of R&D of Porto Editora for making their dictionary available for this research.  ...

A Uniform Method for Automatically Extracting Stochastic Lexicalized Tree Grammars from Treebanks and HPSG [chapter]

Günter Neumann
2003 Text, Speech and Language Technology  
We present a uniform method for the extraction of stochastic lexicalized tree grammars (SLTG) of different complexities from existing treebanks as well as from competence-based grammars , which allows  ...  us to analyze the relationship of a grammar automatically induced from a treebank with respect to its size, its complexity, and its predictive power on unseen data.  ...  In order to automatically enrich the coverage of the extracted grammar, two additional operations are performed during decomposition.  ...

AUTOMATIC ACQUISITION OF A THESAURUS OF INTEROPERABILITY TERMS

Roberto Navigli, Paola Velardi
2005 IFAC Proceedings Volumes  
Statistical and text mining techniques have been used to extract a glossary of relevant terms and term definitions, as well as a preliminary taxonomic structure of the glossary.  ...  In this paper we describe an experiment, conducted within the INTEROP Network of Excellence (NoE), aimed at automatically extracting a thesaurus of interoperability terms from the web and a corpus of available  ...  Parse definitions to extract kind-of information The CF grammar of step 3.1 is again used to extract kind-of relations from natural language definitions.  ...

A Domain Specific Language for Extracting Models in Software Modernization [chapter]

Javier Luis Cánovas Izquierdo, Jesús García Molina
2009 Lecture Notes in Computer Science  
Modeldriven software modernization requires a first step for the extraction of models. Most modernization scenarios involve dealing with the GPL source code of the existing system.  ...  Moreover, the approach also allows reusing existing grammars.  ...  Grammar-based approaches are oriented towards automatically generating metamodels from grammars, whereas metamodel-based approaches work in the opposite direction.  ...

Schema extraction from XML collections

Boris Chidlovskii
2002 Proceedings of the second ACM/IEEE-CS joint conference on Digital libraries - JCDL '02  
We model the XML schema as extended context-free grammars and develop a novel extraction algorithm inspired by methods of grammatical inference.  ...  As schemas remain optional for XML, we address the problem of XML Schema extraction.  ...  The ECFG-based schema model targets a core set of features of the XML Schema language [1] so that any XML Schema definition corresponds to some extended context free grammar and vice versa.  ...

To appear in The Pre-proceedings of the First International Workshop on Bidirectional Transformation (BX 2012), March 2012.  ...  In §3, we have stated that the only way to compare parsers directly and automatically was grammar-based differential testing, which is not completely true.  ...  For defining a purely bidirectional language based on XBGF, we had to address the remaining issues: for example, the XBGF operator extract (introduction of a new nonterminal with its subsequent folding  ...
