We introduce a dialogue task between a virtual patient and a doctor where the dialogue system, playing the patient part in a simulated consultation, must reconcile a specialized level, to understand what the doctor says, and a lay level, to output realistic patient-language utterances. This increases the challenges in the analysis and generation phases of the dialogue. This paper proposes metho...

Keeping pace with other wordnets development, we present the challenges raised by the Romanian derivational system and our methodology for identifying derived words and their stems in the Romanian Wordnet. To attain this aim we rely only on the list of literals in the wordnet and on a list of Romanian affixes; the automatically obtained pairs require automatic and manual validation, based on a ...

negative-maker affixes are those linguistic elements that are widely used in word making. the function and the type of each of these affixes are unique and different from others. the russian affix ??-, for example, in its combination with pronouns and adverbs, makes non-referential sentences that use the infinitive form of the verb, while the affix ??- in its combination with pronouns and adver...

Pronominal affixes in polysynthetic languages have an ambiguous status in the sense that they have characteristics normally associated with free pronouns as well as characteristics associated with agreement markers. This situation arises because pronominal affixes represent intermediate stages in a diachronic development from independent pronouns to agreement markers. Because this diachronic ch...

Melissa Frazier: Accent In Proto-Indo-European Athematic Nouns: Antifaithfulness in Inflectional Paradigms (Under the direction of Jennifer L. Smith) This paper examines four accent patterns displayed by athematic nouns in Proto-Indo-European. Each accent pattern is distinguished by either alternating stress or vowel quality between " weak " forms (nominative, accusative, vocative) and " strong...

A stemming is a technique used to reduce words to their root form, by removing derivational and inflectional affixes. The stemming is widely used in information retrieval tasks. Many researchers demonstrate that stemming improves the performance of information retrieval systems. Porter stemmer is the most common algorithm for English stemming. However, this stemming algorithm has several drawba...

Rapid and automatic processing of grammatical complexity is argued to take place during speech comprehension, engaging a left-lateralized fronto-temporal language network. Here we address how neural activity in these regions is modulated by the grammatical properties of spoken words. We used combined magneto- and electroencephalography to delineate the spatiotemporal patterns of activity that s...

We study the derivational complexity induced by the dependency pair method, enhanced with standard refinements. We obtain upper bounds on the derivational complexity induced by the dependency pair method in terms of the derivational complexity of the base techniques employed. In particular we show that the derivational complexity induced by the dependency pair method based on some direct techni...

Arabic is the fourth most widely spoken language in the world, and is characterised by a high rate of inflection. To cater for this, most Arabic information retrieval systems incorporate a stemming stage. Most existing Arabic stemmers are derived from English equivalents; however, unlike English, most affixes in Arabic are difficult to discriminate from the core word. Removing incorrectly ident...
