The paper describes a procedure for the automatic generation of a large full-form lexicon of English. We put emphasis on two statistical methods to lexicon extension and adjustment: in terms of a letter-based HMM and in terms of a detector of spelling variants and misspellings. The resulting resource, ColLex.EN, is evaluated with respect to two tasks: text categorization and lexical coverage by...

In this paper the role of the lexicon within typical application tasks based on NLP is analysed. A large scale semantic lexicon is studied within the framework of a NLP application. The coverage of the lexicon with respect the target domain and a (semi)automatic tuning approach have been evaluated. The impact of a corpus-driven inductive architecture aiming to compensate lacks in lexical inform...

We propose an extension of Stabler’s version of clitics treatment for a wider coverage of the french language. For this, we present the lexical entries needed in the lexicon. Then, we show the recognition of complex syntactic phenomenae as (left and right) dislocation, clitic climbing over modal and extraction from determiner phrase. The aim of this presentation is the syntaxsemantic interface ...

In this paper we describe the mapping of Zaliznjak’s (1977) morphological classes into the lexical representation language DATR (Evans and Gazdar 1996). On the basis of the resulting DATR theory a set of fully inflected forms together with their associated morphosyntax can automatically be generated from the electronic version of Zaliznjak’s dictionary (Ilola and Mustajoki 1989). From this data...

Most existing systems for automatically extracting lexical-semantic resources neglect multi-word expressions (MWEs), even though approximately 30% of gold-standard thesauri entries are MWEs. We present a distributional similarity system that identifies synonyms for MWEs. We extend Grefenstette’s SEXTANT shallow parser to first identify bigram MWEs using collocation statistics from the Google WE...

We report a Japanese parsing system with a linguistically fine-grained grammar based on the Lexical-Functional Grammar (LFG) formalism. The system is the first Japanese LFG parser with over 97% coverage for real-world text. We evaluated the accuracy of the system comparing it with standard Japanese dependency parsers. The LFG parser shows roughly equivalent performance on the dependency accurac...

In this study, the TÜBİTAK-UEKAE statistical machine translation system based on the open-source phrasebased statistical machine translation software, Moses, is presented. Additionally, phrase-table augmentation is applied to maximize source language coverage; lexical approximation is applied to replace out-of-vocabulary words with known words prior to decoding; and automatic punctuation insert...

This task combines the labeling of multiword expressions and supersenses (coarse-grained classes) in an explicit, yet broad-coverage paradigm for lexical semantics. Nine systems participated; the best scored 57.7% F1 in a multi-domain evaluation setting, indicating that the task remains largely unresolved. An error analysis reveals that a large number of instances in the data set are either har...

This paper introduces the main components of the downloadable package of the 3.0 version of the morphological analyser for Latin Lemlat. The processes of word form analysis and treatment of spelling variation performed by the tool are detailed, as well as the different output formats and the connection of the results with a recently built resource for derivational morphology of Latin. A light e...
