semantic classes of verbs

The main ones are BE, which represents a state, and GO, which represents any event. singen, arbeiten, schlagen, essen, anrufen, spielen, erschießen, zerstören, bauen, helfen, lesen, gehen, schreiben, lachen etc. Lexical-semantic verb classifications have proved useful in supporting various natural language processing (NLP) tasks. +char,+ident([thing The following approaches to building verb semantic classes are outlined in this section: verb classes based on syntactic behaviour (alternations), and verb classes formed from semantic criteria such as thematic roles and elements of Lexical Conceptual Structure. Their number remains small, while covering a quite large number of concepts. roles in RRG are independently motivated. specify features, which distinguish one set of the verbs from another set of verbs, then we must specify the roles that occur with verbs Other authors have studied in detail the semantics conveyed by alternations e.g. Relations with other areas of lexical semantics. LCS pattern: [ event Each verb class in VN is completely described by thematic roles, selectional restrictions on the arguments, and frames consisting of a syntactic description and semantic predicates with a temporal function, in a manner … Olga Majewska, Diana McCarthy, Ivan Vulić, and Anna Korhonen. Beth Levin has defined 79 alternations for English. — "The jug was full of water." He also draws attention to the such a verb dictates that the noun to be related is agent which might be further specified as animate. As can be noticed, it is often necessary to add an adverb to make the sentence acceptable. The first argument of a non-motion activity verb is an effector, the participant which does some action and which is unmarked The Lexical Semantics of Verbs II: Aspectual Approaches to Lexical Semantic Representation 1 Aspectual Approaches: An Introduction As verbs denote events that take place in time, can verbs be differentiated according to how the events they denote take place in time? (18.1.2) Inflectional Morphology (a) finite verb forms: reflect the subject-verb agreement in person and number (b) non-finite verb forms (infinitive, gerund, participle) (1) regular flexion > productive/open class: 4 verbal forms Also, as illustrated below, a set of classes (such as movement verbs) does not include all the `natural' classes one may expect (but `completeness' or exhaustiveness has never been claimed to be one of the objectives of this research). Verb NP(location) with NP(+theme), and alternate in: verbs, change of state verbs, perception verbs, verbs of gestures and sign, weather verbs, ... ⇒ yields a fairly fine-grained semantic classification: 48 broad classes or 192 smaller classes. The same situation occurs for the Part-possessor ascension alternation (Ann cuts John's arm semantic-verb-classes. Next, w.r.t. They are certainly less useful in LKB design since they are far from complete and include many forms of exceptions. Contribute verbs (distribute, donate, submit, ...). Besides the theoretical interest, the underlying semantics conveyed by syntactic construction plays an important role in semantic composition and in the formation of lexicalization patterns 2.5.1. These verbs are sometimes called ditransitive verbs. thematic roles were posed as nuclear by Longacre: Experiencer (E), Patient (P), Agent (A), Range (R), Measure (M), Instrument (I), (After Cook [Coo79] pp. This is the case for the Unexpressed object alternation where the object1 is not realized. verbs within the two frameworks share. examples: { such as eatable entity, liquid), constants (representing non- decomposable concepts like e.g. Proceedings of the 11th International Conference on … Now, if we insist, in the ditransitive construction, that the goal must be animate, then we can postulate just one sense for slide, which is intuitively more conceptually appropriate. The method involves first classifying entire WordNet senses to semantic classes and then classifying individual verbs on the basis of their WordNet senses. 2.4 FrameNet5 project is focused mainly on selecting words with particular meanings and The semantic verb class hypothesis Under the semantic verb class hypothesis (Pinker, 1989a: 223) the causative (and anticausative) alternation is governed by a ‘‘broad-range lexical rule’’ which ‘‘allows a verb that specifies an event involving a thing to be embedded as an effect of an agent acting on that thing’’. analysis of verb meanings with regard to the subclassification of verbs into more or less equivalent types; thus states = states, CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We propose a method for semi-automatic classification of verbs to Levin classes via the semantic network of WordNet. livrer, échanger, troquer, abandonner, sacrifier, confier, semantic roles. The verb is Menu. +ident ([thing ], [place ])] arbeiten, schlafen, sehen, laufen, essen, wandern etc. The classes of verbs in the table above cover different cognitive dimensions of language. Four different such types have been identified below. Verbs undergoing this alternation can roughly be characterized as verbs of change of state or position. that indicate the semantic class of the noun – Swahili has one set of singular and plural markers for nouns that ... Semantic Features of Verbs • Verbs can describe events (eventives) or states (statives), and these verbs a#ect the possible sentence structures: This is the case, e.g., for the Characteristic property of agent alternation: relational lexical meanings plays a central role in the classifications of verbs outlined in this subsection. caboter, entourer, prolonger, LCS pattern: [event French and Romance languages in general have much fewer alternations, their syntax is, in a certain way, more rigid. semantic classes of verbs. While verb classes are a mainstay of linguistic research, the field lacks consensus on precisely what constitutes a verb class. Verb NP(+destination) with NP(+theme). number of semantico-syntactic tests that are indicative in distinguishing the basic verb types. Let us now consider the combination of a verb, with its own semantics, within Each verb class in VN is completely described by a set of members, thematic roles for the predicate- argument structure of these members, selectional restrictions on the arguments, and frames consisting of a syntactic description and semantic predicates with a temporal function, in a manner similar to the event decomposition of Moens and Steedman (1988).2 The original Levin classes have been refined … Verbs of this category express a state. Other verbs more naturally take the location/container as object (e.g. The vertical parameter has four values: state verbs, process verbs, Let us now introduce the Lexical Conceptual Structure (LCS), which is an elaborated form of semantic representation, with a strong cognitive dimension. They are based on very different assumptions. kill) and activities (e.g. Regular/Irregular Verbs. one may conclude that there are two senses for slide (probably very close). The horizontal parameter accounts for the die, realise, learn), accomplishments (e.g. Conceptual categories are represented as an indice to a bracketed structure: know, be, have) are taken as basic and other classes are derived from them. attarder, différer, Actions describe something that verb argument does or performs (Harriet sang), Let us now look in more depth at a few classes and somewhat evaluate the use of such classes for natural language applications (note that several research projects make an intensive use of B. Levin's classes). Primitives can then be specialized to a field, e.g. Longacre extended the number of nuclear cases to 10, which resulted in a considerable enlargement of the number of verb classes. Verb semantic classes are then constructed from verbs, modulo exceptions, which undergo a certain number of alternations. verbs not associated with an alternation but which are closely related to verbs which are associated with it, in order to narrow down the semantic characterization of this alternation. The second point concerns the meaning relations between constructions. The light is [state red ]. 2.1 German Semantic Verb Classes A set of 168 German verbs was manually classified into 43 concise semantic verb classes. 2. These categories may be viewed as the roots of a selectional restriction system. VerbNet is organized into verb classes extending Levin (1993) classes through refinement and addition of subclasses to achieve syntactic and semantic coherence among members of a class. The following relations are discussed [Jac83] introduces the notion of conceptual constituent defined from a small set of ontological categories (also called conceptual parts of speech), among which the most important are: thing, event, state, place, path, property, purpose, manner, amount, time. partial semantic representation of the lexical meaning and also as an input to the syntactic operations such as for example GO+poss a change of possession, and The close affinity between the compositional and for volition and control as in The door squeaks. LCS pattern: [event GO }, Verbs of temporal 'motion': The LCS came in part from the Lexical Semantics Templates (see above) and from a large number of observations such as those of [Gru67]. VerbNet (Kipper et al., 2000; Kipper-Schuler, 2005) – the largest computational verb lexicon currently available for English – provides detailed syntactic-semantic descriptions of Levin classes. favour of the variant which includes the information on a partial semantic representation in the lexicon: (i) significant inflection, can change the verb from unaccusative into causative form and vice versa by … Verb NP(+theme) onto NP(+destination), and they alternate in: Other sets of alternations include the introduction of oblique complements, reflexives, passives, there-insertion, different forms of inversions and the introduction of specific words such as the way-construction. Each semantic class is associated with a set of semantic roles which are prototypical for the conceptual domain evoked, so that verbs belonging to the same class will share the same subset of semantic roles. and syntactic representation. With the same contribute to the integration of semantic and syntactic content in the lexicon. Web Design and development New Media - Copyright © 2012 deutschplus. the magazine in The magazine is on the desk. It utilises a modified version of the representational scheme proposed in Dowty They basically describe `transformations' from a `basic' form. These LSs are starting point for the interpretation of the thematic relations in RRG. activity = action, achievement = process, accomplishment = action-process. change of possession, change of property). (1996) semantic verb categories in investigating reporting verbs of college-level students in … More precisely, she shows that some facets of the semantics of verbs have strong correlations with the syntactic behavior of these verbs and with the interpretation of their arguments. One possible distinction within dynamic situation types, for example, is between events and processes. The nature of the verb determines what nouns will accompany it, what the relation of these nouns to it will It is clear that verbs is one of the most central syntactic category in language. the desk is {s'étendre, longer, côtoyer, raser, border, s'étaler, These observations reinforce the arguments in favor of a certain autonomy of lexical semantics. [purpose to prevent a fire ]. This book presents a novel approach to verb classes, employing a bottom-up, corpus-based methodology and combining key insights from Frame Semantics, Construction Grammar, and Valency Grammar. There are other aspects which may weaken the practical use of this approach, in spite of its obvious high linguistic interest, from both theoretical and practical viewpoints. If we now consider the first set of verbs, those whose basic form is more naturally the `into/onto' form, then verbs which have one of the following properties alternate: Inherently directed motion (arrive, go,...). In most cases, the `typical' object is `implicit' or `incorporated' into the verb, or deducible from the subject and the verb. On the other side, certain verb classes that do not clearly match the semantics encoded by to, such as verbs of refusal, do occur in the to-POC (see Quirk et al. turn has to be integrated with the model of syntactic representation. poser, dissiper, extraire, monter, descendre, pénétrer Inferring and evaluating semantic classes of verbs signaling modality. While some properties seem to have a clear ontological status, others seem to be much more difficult to characterize. Thematic relations are defined in terms of These aspects may moreover be surprisingly subtle and refined, and difficult to identify and to describe in a formal system. characterised by these features. Thus achievements which are inchoative semantically are Verbs were controlled for syllable length, picturability, phonological complexity, and frequency. Characteristic for Chafe's approach is the position that a sentence is build around a predicative These two frameworks also show some overlap as far as the semantic affinity of the major - some verbs homonymous with nouns: act, challenge, flood - some verbs homonymous with adjectives: clean, secure, etc. From Lojban. Alternations may also be restricted by means of constraints on their arguments. leben, sein, wohnen, liegen, sich befinden, schlafen etc. This is not very surprising, since syntactic alternations form a set of closed elements.
