Multi-level information and automatic dialog act detection in human-human spoken dialogs

Sophie Rosset; Delphine Tribout; Lori Lamel

This paper reports studies on annotating and automatically detecting dialog acts in human-human spoken dialogs. The work reposes on three hypotheses: first, the succession of dialog acts is strongly constrained; second, the initial word and semantic class of word are more important for identifying dialog acts than the complete exact word sequence of an utterance; third, most of the important information is encoded in specific entities. A memory based learning approach is used to detect dialog acts. For each utterance unit, eight dialog acts are systematically annotated. Experiments have been conducted using different levels of information, with and without the use of dialog history information. In order to assess the generality of the method, the specific entity tag based model trained on a French corpus was tested on an English corpus for a similar task and on a French corpus from a different domain. A correct dialog act detection rate of about 86% is obtained for the same domain/language condition and 77% for the cross-language or cross-domain conditions.

Morphological Resources for Precise Information Retrieval

Anne-Laure Ligozat; Brigitte Grau; Delphine Tribout

Question answering (QA) systems aim at providing a precise answer to a given user question. Their major difficulty lies in the lexical gap problem between question and answering passages. We present here the different types of morphological phenomena in question answering, the resources available for French, and in particular a resource that we built containing deverbal agent nouns. Then, we evaluate the results of a particular QA system, according to the morphological knowledge used.

De-adjectival Human Nouns in French

Dany Amiot; Delphine Tribout

This chapter deals with adjectives used as nouns in French. Such uses of adjectives are cross-linguistically attested, and in recent years there have been numerous studies on this topic, often in a cross-linguistic perspective. Two kinds of interpretation are generally distinguished for these nouns: either the noun is abstract and refers to the property denoted by the adjective; or it is concrete and countable and refers to an individual, generally a human being. This study will focus on the latter, named de-adjectival human nouns. We will first present the main properties of de-adjectival human nouns in French, then we will give an account of the literature on de-adjectival nouns. Such nouns are generally analysed as being either syntactically derived or morphologically converted from adjectives. We will show, however, that both types of analysis suffer drawbacks. Finally, in line with the framework of Construction Grammar, we will provide an alternative analysis, in terms of syntactic coercion.

The semantics of underived event nouns in French

Richard Huyghe; Lucie Barque; Pauline Haas; Delphine Tribout

This paper deals with underived nouns that denote events in French (e.g. crime ‘crime’, proces ‘trial’, emeute ‘riot’, seisme ‘earthquake’). We compare the properties of these nouns with those of deverbal nominalizations, especially as regards complement structure and lexical aspect. The heterogeneity and specificities of underived event nouns (UENs) are highlighted. First, the event denotation for UENs can have various semantic origins, and be derived metaphorically or metonymically from a non-event meaning. Second, some UENs are completely autonomous event nouns and never combine with participant-denoting complements, whereas others are role assignors and determine the semantics of their prepositional complements. Despite those specificities, UENs share many properties with deverbal event nouns, most notably regarding lexical aspect. UENs can denote durative or punctual, telic or atelic, foreseen or unforeseen events. We argue that lexical aspect is not primarily a property of verbs. It is a matter of semantic rather than grammatical categories, and fundamentally depends upon the denotation of eventualities
