The classification of verbs in Levin's (1993) English Verb Classes and Alternations: A preliminary Investigation, on the basis of both intuitive semantic grouping and their participation in valence alternations, is often used by the NLP community as evidence of the semantic similarity of verbs (Jing & McKeown 1998; Lapata & Brew 1999; Kohl et al. 1998). In this paper, we compare the Levin classification with the work of the FrameNet project (Fillmore & Baker 2001), where words (not just verbs) are grouped according to the conceptual structures (frames) that underlie them and their combinatorial patterns are inductively derived from corpus evidence. This means that verbs grouped together in FrameNet (FN) might be semantically similar but have different (or no) alternations, and that verbs which share the same alternation might be represented in two different semantic frames.
Der Beitrag beschäftigt sich mit den verschiedenen Such-, Auffindungs- und Auswahlsprozessen, die für die fremdsprachige Produktion notwendig sind und von DICONALE-online, einem onomasiologisch-konzeptuell ausgerichteten, zweisprachig-bilateral konzipierten Verbwörterbuch der spanischen und deutschen Gegenwartsspache, besonders berücksichtigt werden. Der Ausgangspunkt von DICONALE ist ein unbefriedigendes Informationsangebot in den bestehenden ein- und zweisprachigen Lernerwörterbüchern für den L2-output und bestätigt das Projektteam in der Notwendigkeit, ein neuartiges benutzer- und situationsdefiniertes online-Nachschlagewerk zu erstellen. Zwei Bezugsrahmen bilden die Grundlage für einen komplexen, konzeptuell und framegeleiteten Zugriffspfad, der dem Benutzer bei der Suche und Auswahl von Ausdrucksmöglichkeiten und der adäquaten Anwendung behilflich sein soll. Das Novum dieses Wörterbuchprojekts besteht hauptsachlich darin, eine onomasiologisch-konzeptuelle Perspektive für den fremdsprachigen Produktionsprozess nutzbar zu machen und mit einem semasiologischen Zugriff zu verbinden, durch den es möglich ist, die inter- und intralingualen Unterschiede zwischen den Lexemen eines lexikalisch-semantischen (Sub)Paradigmas hervorzuheben. Ziel des Beitrages ist es daher, den Ausgangspunkt, sowie die theoretischen und methodologischen Grundlagen von DICONALE-online unter der speziellen Perspektive der Benutzer- und Situationsorientiertheit zur Diskussion zu stellen, die einzelnen Zugriffspfade für den Such- und Auffindungsprozess vorzustellen und das Angebot zur Auswahl und zum adäquaten Gebrauch aus inter- und intralingualer Perspektive zu präsentieren.
Opinion Holder and Target Extraction for Verb-based Opinion Predicates – The Problem is Not Solved
(2015)
We offer a critical review of the current state of opinion role extraction involving opinion verbs. We argue that neither the currently available lexical resources nor the manually annotated text corpora are sufficient to appropriately study this task. We introduce a new corpus focusing on opinion roles of opinion verbs from the Subjectivity Lexicon and show potential benefits of this corpus. We also demonstrate that state-of-the-art classifiers perform rather poorly on this new dataset compared to the standard dataset for the task showing that there still remains significant research to be done.
In this paper we present a new approach to lexicographical design for the description of German speech act verbs. This approach is based on an action-theoretical semantic conception. The several conditions for linguistic action provide the basis for the elaboration of the central semantic features. The systematic relationship of these features is reflected in the organization of a lexical database which allows various possibilities of access to different types of lexical information.
In the following paper we shall give an outline of the semantic framework for describing speech act verbs, i. e. verbs of communication, with the practical goal of a semantical database for a (dictionary of) synonymy of German speech act verbs which enables the user not only to find a list of synonymous verbs but also enables him to gain an insight into the semantic relations between the words.
The semantic framework is based on
(i) a set of conditions for performing speech acts as the relevant domain of reference
(ii) the introduction of a notion of situation, or better type of situation
The performative as well as the descriptive use of the verbs can be reduced to their fundamental dependency on the situations in which they are used: on the one hand with regard to the possibility of the action itself, and on the other hand with regard to the possibility of their designation. For both ways of use the relevant aspects of the situation constitute the necessary conditions.
Centering on German self-motion verbs, this paper demonstrates the advantages of free-sorting over creating and delineating word fields with more traditional methods. In particular, I draw a comparison to Snell-Hornby’s (1983) work on German descriptive verbs, which produces lexical fields with the help of dictionary entries, a thesaurus, a small corpus of written text and limited speaker feedback. While these methods have benefits, they are limited in their ability to represent the average organization of semantic fields in the mind of everyday speakers. Freesorting, by contrast, does not rely on academic resources, corpora or singular speaker judgments. In sorting, a group of informants creates visible sets of items according to perceived similarity. Psycholinguists have used the method to quantitatively explore the perception of color terms across cultures (c.f. Roberson et al. 2005). With a sufficiently large number of informants, one can generate lexical sorting data that is apt for cluster analysis, the results of which are represented by dendrograms. The experiment I conducted involved 33 school children from a middle class neighborhood in Braunschweig, Northern Germany. My experiment shows that Snell-Hornby’s (1983) representation of the self-motion field can be improved by integrating further dimensions of meaning, such as body-space relations and sound, that young speakers find salient in the grouping procedure.
This essay is concerned with the event structure of verbs of communication. Some verbs of communication cannot easily be classified as belonging to a particular type of event structure, while others are basically Activity predicates. We show that this difference with respect to event structure depends on the lexicalization of speaker attitudes. Those verbs of communication which do not express any particular speaker attitude can be assigned an Activity event structure, which can then be expanded to yield an Accomplishment. However, genuine speech act verbs, i. e. verbs which are specified with respect to speaker attitudes, do not correspond to any event structure type and do not allow a similar expansion of their argument structure.
This contribution deals with the representation of verbs with multiple meanings or senses in general monolingual dictionaries. Criteria for differentiating senses in dictionary entries have traditionally been formulated with respect to the vocabulary in general. This paper argues that, while some criteria do indeed apply to the entire lexicon, many of them are relevant only to specific semantic classes. This will be demonstrated considering two selected verb classes: speech-act verbs and perception verbs. Like verbs of other classes, speech-act verbs and perception verbs may be ambiguous in different but recurrent ways. Since recurrent patterns of ambiguity are always typical of particular semantic classes, class-specific semantic criteria are formulated to decide whether a particular ambiguous speech act or perception verb should be treated as being polysemous or homonymous in dictionary entries. In addition to these class-specific semantic criteria, the semantic-syntactic criterion of identity or difference of argument structure is suggested for the lexicographical representation of verbs which may not be considered to be polysemous or homonymous on the basis of semantic criteria alone. According to the suggested argument-structure criterion, these verbs should be treated as polysemous when their senses correlate with identical argument structures and as homonymous when their senses correlate with different argument structures properties. As opposed to the semantic criteria suggested, the semantic-syntactic criterion of identity vs. difference of argument structure applies to verbs of different semantic classes. However, as will be illustrated by the discussion of the different senses of smell, it may sometimes force us to treat different but related senses as corresponding to two distinct lexical items. In order to solve this problem, the criteria suggested are supplemented by a preference rule stating that semantic criteria apply prior to the semantic-syntactic criterion of identity vs. difference of argument structure...
Kommunikationsverben, an online reference work on German communication verbs and part of the dictionary portal OWID, describes the meaning of communication verbs on two levels: a lexical level, represented in the dictionary entries and by sets of lexical features, and a conceptual level, represented by different types of situations referred to by specific types of verbs. These two levels have each been implemented in special types of access structures. A first explorative access to the conceptual level provides the user with a list of the main classes of communication verbs, the subclasses of each of these, and the lexical fields pertaining to each subclass. Lexical fields are presented together with a characterisation of the situation type to which the verbs of that field are used to refer. Information about the conceptual level is additionally accessible by an advanced search option allowing the user to combine components of the characterisation of situation types to “create” any kind of situation and search for the verbs that correspond to it. Information about the lexical level of the meaning of communication verbs is accessible via the dictionary entries and by another advanced search option allowing the user to search for verbs with particular lexical features or combinations of these.
Whether verbs have to be marked as punctual vs. durative has been a controversial issue from the very beginnings of research on aktionsarten in the last century right on up to modern theories of aspectual classes and aspect composition. Debates about the linguistic necessity of this distinction have often been accompanied by the question of what it means for a verb to be temporally punctual. In this paper I will, firstly, sketch the history of research on the punctual-durative distinction and present several linguistic arguments in its favor. Secondly, I will show how this distinction is captured in an eventstructure- based approach to lexical semantics. Thirdly, I will discuss the extent to which a precise definition of the notions used in lexical
representations helps avoid circular argumentation in lexical semantics. Finally, I will demonstrate how this can be done for the notion of ‘punctuality’ by clarifying the logical type of this predicate and relating it to central cognitive time concepts.
