In this paper, we first analyze and classify the empty categories in a Hindi dependency treebank and then identify various discovery procedures to automatically detect the existence of these categories in a sentence. For this we make use of lexical knowledge along with the parsed output from a constraint based parser. Through this work we show that it is possible to successfully discover certai...

In this paper, I will discuss four major topics relating to current research in lexical semantics: methodology, descriptive coverage, adequacy of the representation, and the computational usefulness of representations. In addressing these issues, I will discuss what I think are some of the central problems facing the lexical semantics community, and suggest ways of best approaching these issues...

Indonesian is known for having a relatively simple morphological and syntactic structure. This is especially true of local varieties of the language, where contrast between categories found in Standard Indonesian is neutralized. In the Indonesian variety spoken in Riau Province, there is almost no morphological marking of grammatical categories and there is relatively free word order. Gil (1994...

Native tonal-language speakers exhibit reduced sensitivity to lexical tone differences within, compared to across, categories (higher-level linguistic category influence). Yet, sensitivity is enhanced among musically trained, non-tonal-language-speaking individuals (lower-level acoustics processing influence). The current study investigated the relative contribution of higher- and lower-level i...

In this paper we present a self-organizing neural network model of early lexical development called DevLex. The network consists of two self-organizing maps (a growing semantic map and a growing phonological map) that are connected via associative links trained by Hebbian learning. The model captures a number of important phenomena that occur in early lexical acquisition by children, as it allo...

1 Morphology with or without Affixes The last few years have seen the emergence of several clearly articulated alternative approaches to morphology. One such approach rests on the notion that only stems of the so-called lexical categories (N, V, A) are morpheme "pieces" in the traditional sense—connections between (bundles of) meaning (features) and (bundles of) sound (features). What look like...

We present a prototype model, based on a combination of count-based distributional semantics and prediction-based neural word embeddings, which learns about syntactic categories as a function of (1) writing contextual, phonological, and lexical-stress-related information to memory and (2) predicting upcoming context words based on memorized information. The system is a first step towards utiliz...

We describe how the use o1' at hierarchy of lexical categories instead of a simple set of categories leads to the definition of a flexible and precise language for the description of dependency structures. After specifying the t'ormalism we use to decorate these structures, we present an application aiming to detect and correct en'ors in a written text. We outline how tile use of the h ierarchy...

Event types (ET) have been widely addressed in linguistic literature, but few studies have dealt with the questions of how they are represented, retrieved and processed in the mental lexicon. We report two experiments in which ET categories were found to give rise to semantic priming effects, both with word and picture stimuli. These effects are argued to provide empirical correlates for ET cat...
