Dialogue Act (DA) classification is the task of classifying utterances with respect to the function they serve in a dialogue. Existing approaches to DA classification model utterances without incorporating the turn changes among speakers throughout t
he dialogue, therefore treating it no different than non-interactive written text. In this paper, we propose to integrate the turn changes in conversations among speakers when modeling DAs. Specifically, we learn conversation-invariant speaker turn embeddings to represent the speaker turns in a conversation; the learned speaker turn embeddings are then merged with the utterance embeddings for the downstream task of DA classification. With this simple yet effective mechanism, our model is able to capture the semantics from the dialogue content while accounting for different speaker turns in a conversation. Validation on three benchmark public datasets demonstrates superior performance of our model.
This study proposes an utterance position-aware approach for a neural network-based dialogue act recognition (DAR) model, which incorporates positional encoding for utterance's absolute or relative position. The proposed approach is inspired by the o
bservation that some dialogue acts have tendencies of occurrence positions. The evaluations on the Switchboard corpus show that the proposed positional encoding of utterances statistically significantly improves the performance of DAR.
Alzheimer's Disease (AD) is associated with many characteristic changes, not only in an individual's language but also in the interactive patterns observed in dialogue. The most indicative changes of this latter kind tend to be associated with relati
vely rare dialogue acts (DAs), such as those involved in clarification exchanges and responses to particular kinds of questions. However, most existing work in DA tagging focuses on improving average performance, effectively prioritizing more frequent classes; it thus gives a poor performance on these rarer classes and is not suited for application to AD analysis. In this paper, we investigate tagging specifically for rare class DAs, using a hierarchical BiLSTM model with various ways of incorporating information from previous utterances and DA tags in context. We show that this can give good performance for rare DA classes on both the general Switchboard corpus (SwDA) and an AD-specific conversational dataset, the Carolinas Conversation Collection (CCC); and that the tagger outputs then contribute useful information for distinguishing patients with and without AD
We use dialogue act recognition (DAR) to investigate how well BERT represents utterances in dialogue, and how fine-tuning and large-scale pre-training contribute to its performance. We find that while both the standard BERT pre-training and pretraini
ng on dialogue-like data are useful, task-specific fine-tuning is essential for good performance.
Formal semantics in the Montagovian tradition provides precise meaning characterisations, but usually without a formal theory of the pragmatics of contextual parameters and their sensitivity to background knowledge. Meanwhile, formal pragmatic theori
es make explicit predictions about meaning in context, but generally without a well-defined compositional semantics. We propose a combined framework for the semantic and pragmatic interpretation of sentences in the face of probabilistic knowledge. We do so by (1) extending a Montagovian interpretation scheme to generate a distribution over possible meanings, and (2) generating a posterior for this distribution using a variant of the Rational Speech Act (RSA) models, but generalised to arbitrary propositions. These aspects of our framework are tied together by evaluating entailment under probabilistic uncertainty. We apply our model to anaphora resolution and show that it provides expected biases under suitable assumptions about the distributions of lexical and world-knowledge. Further, we observe that the model's output is robust to variations in its parameters within reasonable ranges.
The purpuse of the speech whatever its type is the inflence so the speaker tries so hard to
produse linguistic words that direct the reciever towards a specific action.The importance
of the argumintation theory lies in the depending on the speech t
echniques which the
sender use in the speech .And which make his speech acceptable to the reciever.The
argumentation theory started in the fields of Linguistics ,Logic ,Anthropology…etc and
different other sciences.It becomes a complete theory after Perlman's researches which the
scientists work on.All the analytists and researchers get benefit from in the communication
and connecting theory.Relying on the speaker's techniques in achieving a successful
connecting that leags to a real communication is the purpose of argumenation theory which
is a still growing.And which considers the speech act theory as a scientific background.
The research attempts to compromise a linguistic case to be understand able it’s the
theory in phase the formation, and it is the detection hangs in about the image which
appeared in its personality of the oratorical self, the transformations which
occurred on it,
and their application mechanism to a linguistic text which is the speech of AL- HASAN
Ibn ALI Ibn ABI TALEB In Sabatt.
Moreover, The research attempts to set up a compromise that clarifies both sides of
saying: theoretical and practical, so the research to importance indicated the rhetoric in
describing its industry, and seeks to attracting the addresses "receivers" and the impacting
and persuading them, and explain the components of the communication process, and
illustrated the manifestations of the ethos, started with the advanced ethos that pertains to
the person speaking, and through the oratorical ethos, it is the image that the speech
producer tried to construct in the text, to reach the image of the self was formed after the
end of the discourse, which proposed usher naming the post-rhetorical ethos, and how the
recipient rebelled against the preacher when the third verb of the speech act was achieved.
The analytical descriptive and method might sound the perfect way via which one
can get to the speech of AL- HASAN Ibn ALI, analysis of procedural processes in the
study of linguistic phenomena after determining their scope time and environment, and
detecting shifts in the image of the discourse product "ethos" .
Children constitute a large proportion of the Syrian society, where
each is a child who has not attained the age of eighteen years of age,
according to the Syrian legislation. And exposed by virtue of their
circumstances and the early age at risk
of exploitation, more than
others, and the longer exploitation all take advantage of these
children at the expense of their basic rights, and among the most
important aspects of labor exploitation in the work without a
specific law on the Syrian people.
Investigation was carried out in Izraa research station /Daraa
Research Center/GCSAR (Damascus, Syria), during the agricultural
seasons 2012/2013 and 2013/2014. Parents and hybrids were planted
by randomized complete block design ،the
results we
re analyzed by averages generation’s method to study the
genetic variation components of some morphological and quantity
treats (days to maturity, pods per plant, high and wide of plant,
high of first pod, weight of 100 seeds, and seed yield).
In this research I'm going to expose Averroes maturity conception of legal movement to occur in the world and among the assets ; as long as the assets are composed of material and form , the movement depends on the union between material and form unt
il you get to the process of trans formation of the power in herent in the material by the action in the form .
And here comes the role of the actor which moves the material toward the union with form through movement , so the movement also serves as a process of the dialectic between the material and form that consist the nature of the assets in the world , and thus show the the movement it is bringing out of material to the form by the dialectic of power and action by becoming kinetic between assets
Thus , the conception of movement to Averroes highlights the important of form power and act as essential elements for the occurrence in existence . He stressed the vole of each element in the movement as well as the movement needs an actor and moving thing which are (material ,form, actor).
