In natural language generation, the use of a lexicalized grammar formalism and incremental syntactic and semantic processing places strong and specific constraints on the form and meaning of grammatical entries. These principles restrict which grammatical representations are possible and suggest examples an analyst can consult to decide among possibilities. We discuss and justify a number of su...

This paper deals with the derivational morphology of automatic word form recognition. It presents a set of declarative rules which augment lexical entries with information governing the allomorphic changes of derivation in addition to the existing allomorphy rules for inflection. The resulting component generates a single lexicon for derivational and inflectional allomorphy from an elementary b...

Two problematic issues in most lexicon systems today are their size and restricted domain of use. In this paper, we introduce a new approach to lexical organization that leads to more compact and flexible lexicons. The lexical entries are conceptual/phonological frames rather than word entries, and a number of expansion rules are used to generate entries of actual words from these frames. A sin...

This paper describes a HMM-based chunk tagger and its extensions used in KRDL for the shared task of CoNLL'2000. Compared with standard HMM-based tagger, this tagger incorporates more contextual information into a lexical entry. Moreover, an error-driven learning approach is adopted to decrease the memory requirement. It keeps only positive lexical entries which contribute to the error reductio...

Recognition using only visual evidence cannot always be successful due to limitations of information and resources available during training. Considering relation among lexicon entries is sometimes useful for decision making. In this paper, we present a method to capture lexical similarity of a lexicon and reliability of a character recognizer which serve to capture the dynamism of the environm...

The purpose of this study was to investigate the mental representation of cognate and noncognate translation pairs in languages with different scripts to test the prediction of dual lexicon model (Gollan, Forster, & Frost, 1997). Two groups of Persian-speaking English language learners were tested on cognate and noncognate translation pairs in Persian-English and English-Persian directions with...

Research in Construction Grammar assumes no strict separation between syntax and the lexicon. However, recent work by Goldberg (1995, 2006) shows that there is indeed a separation between lexical entries and grammatical constructions, including constraints regulating the fusion of grammatical constructions with verbs. This paper argues that Goldberg’s characterization of the interactions betwee...

This paper describes the conversion into LMF, a standard lexicographic digital format of ’al-qāmūs al-muh. īt . , a Medieval Arabic lexicon. The lexicon is first described, then all the steps required for the conversion are illustrated. The work is will produce a useful lexicographic resource for Arabic NLP, but is also interesting per se, to study the implications of adapting the LMF model to ...

A theory of interlanguage (IL) lexicons is outlined, with emphasis on IL lexical entries, based on the HPSG notion of lexical sign. This theory accounts for idiosyncratic or lexical transfer of syntactic subcategorisation and idioms from the first language to the IL. It also accounts for developmental stages in IL lexical grammar, and grammatical variation in the use of the same lexical item. T...

We introduce a method for data-driven learning of lexical entries in an inherently incremental semantic grammar formalism, Dynamic Syntax (DS). Lexical actions in DS are constrained procedures for the incremental projection of compositional semantic structure. Here, we show how these can be induced directly from sentences paired with their complete propositional semantic structures. Checking in...
