Abstract Aspect level sentiment analysis belongs to fine-grained sentiment analysis, w hich has caused extensive research in academic circles in recent years. For this task, th e recurrent neural network (RNN) model is usually used for feature extraction, but the model cannot effectively obtain the structural information of the text. Recent studies h ave begun to use the graph convolutional network (GCN) to model the syntactic depen dency tree of the text to solve this problem. For short text data, the text information is not enough to accurately determine the emotional polarity of the aspect words, and the knowledge graph is not effectively used as external knowledge that can enrich the sem antic information. In order to solve the above problems, this paper proposes a graph co nvolutional neural network (GCN) model that can process syntactic information, know ledge graphs and text semantic information. The model works on the “syntax-knowled ge” graph to extract syntactic information and common sense information at the same t ime. Compared with the latest model, the model in this paper can effectively improve t he accuracy of aspect-level sentiment classification on two datasets.

As an important branch of Nature Language Processing (NLP), how to extract useful text information and effective long-range associations has always been a bottleneck for text classification. With the great effort of deep learning researchers, deep Convolutional Neural Networks (CNNs) have made remarkable achievements in Computer Vision but still controversial in NLP tasks. In this paper, we propose a novel deep CNN named Deep Pyramid Temporal Convolutional Network (DPTCN) for short text classification, which is mainly consisting of concatenated embedding layer, causal convolution, 1/2 max pooling down-sampling and residual blocks. It is worth mentioning that our work was highly inspired by two well-designed models: one is temporal convolutional network for sequential modeling; another is deep pyramid CNN for text categorization; as their applicability and pertinence remind us how to build a model in a special domain. In the experiments, we evaluate the proposed model on 7 datasets with 6 models and analyze the impact of three different embedding methods. The results prove that our work is a good attempt to apply word-level deep convolutional network in short text classification.

<div><em>The article presents the results of the study of the communicative competence of the politicians on the basis of the analysis of their messages on their official pages of the Facebook social network. The research used the following general scientific methods: descriptive and comparative, as well as analysis, synthesis and generalization. The quantitative content analysis method with qualitative elements was used to distinguish the peculiarities of information messages that provide communication of the deputies of Verkhovna Rada (Ukrainian Parliament) on their official Facebook pages. Information messages have been analyzed by the following three criteria: subject matter, structure and language.</em></div><p> </p><p><em>For the first time the article draws a parallel between communicative competence and the ability to communicate with voters on the official pages of Facebook which is the most popular social network in Ukraine. As it is established, communicative competence in the analyzed cases is caused not by education, but by previous professional activity of a politician. The most successful and high-quality communication was from the current parliamentarian who worked as a journalist in the past. More than half of the messages that provided successful communication consisted of sufficiently structured short text and a video. The topic covers the activity of the parliamentarian in the Verkhovna Rada and in his district. More than half of the messages are spoken in the first person.</em></p><p><em>The findings of the study can be used in teaching such subjects as Political PR and Electronic PR, and may be of interest to politicians and their assistants.</em><em></em></p><p><strong><em>Key words:</em></strong><em> competence and competency, communicative competence, political discourse, official page of the deputy of Verkhovna Rada of Ukraine on the Facebook social network, subject matter and structure of the information message, first-person narrative, correspondence of communication to the level of communicative competence.</em></p>

A method for solving the problem of classifying short-text messages in the form of sentences of customers uttered in talking via the telephone line of organizations is considered. To solve this problem, a classifier was developed, which is based on using a combination of two methods: a description of the subject area in the form of a hierarchy of entities and plausible reasoning based on the case-based reasoning approach, which is actively used in artificial intelligence systems. In solving various problems of artificial intelligence-based analysis of data, these methods have shown a high degree of efficiency, scalability, and independence from data structure. As part of using the case-based reasoning approach in the classifier, it is proposed to modify the TF-IDF (Term Frequency - Inverse Document Frequency) measure of assessing the text content taking into account known information about the distribution of documents by topics. The proposed modification makes it possible to improve the classification quality in comparison with classical measures, since it takes into account the information about the distribution of words not only in a separate document or topic, but in the entire database of cases. Experimental results are presented that confirm the effectiveness of the proposed metric and the developed classifier as applied to classification of customer sentences and providing them with the necessary information depending on the classification result. The developed text classification service prototype is used as part of the voice interaction module with the user in the objective of robotizing the telephone call routing system and making a shift from interaction between the user and system by means of buttons to their interaction through voice.

The relevance of this publication is linked to the constant expansion of the range of packing products offered to the consumer market and the need to ensure the communicative function of packaging that embodies the dual requirements, one of which is the need for assimilation products to existing trade row, and the other - the selection of merchandise goods number by packing. The goal is to highlight all aspects of the problem associated with the communicative function of packaging products and outline the ways to solve them. Research Methodology: a tested method of complex analysis is introduced. It establishes the presence of domestic communicative aspects relevant to each of the above requirements and ways to implement them through the provision of a number of design techniques that can be guided by the designer in the implementation of project tasks. The scientific novelty is to identify all aspects of the communication requirements for packaging products and to establish conformity between each aspect and design methods that ensures their implementation. The advantages and disadvantages of each of the methods are considered in detail, namely: demonstration of images of the idealized consumer (advertising character) or the image of the idealized commodity producer; demonstration of hyperbolized consumer goods characteristics; accentuation of awards and signs of ecological safety; the dominance of typographic design and advertising block units over figurative elements; introduction of innovative and original shaping in packing designs. The importance of formulation of assortment of packaging products is separately highlighted, which represents a specific visual text - information that allows to trace the functional purpose of packaging and the presence of common and distinctive features. The studies have found that methods of demonstration images of idealized consumer (advertising character) or an idealized image producers meet the communication requirements such as: instant identification of goods, providing clear and unambiguous information about its content; the requirements for attracting attention through the visual images embodied in the packaging; creation of attractive communicative images from consciously active to accented-neutral. However, advertising characters are more likely to personally consciously active images. At the same time not all consumers are convinced of the perception of such an active position. The consideration of the mentality of such consumers makes it possible to resort to demonstration of images of the final product with hyperbolized consumer qualities. The use of such reception is the most common way of presenting food products under the conditions present in Slavic commodity markets and sometimes leads to the effect of over-supply of properties of such goods in an idealized form that loses communication product in real disposable bag. Obviously, the observation of differences between desired and available product features can lead only to a single act of purchase, and not contribute to the establishing the long-term relationships that can work for the nprestige and multiple acquisition of a proposed brand. Further, correlating techniques of sense formation with the communicative aspects of packaging products, the matching between the methods of emphasis of awards and signs of environmental safety requirements of trusted sources of information were found, that leads to the creation of the impression of reliability. Specific kind of project reception focused on building confidence in the source of information, creation of a correlation to such a source of impression of reliability is the introduction of TM with loud names such as "Our product", "Without GMOs". Names such as awards and environmental safety receive dominant positions in the system of information and communication elements of packaging products and focus on consumers' attention. The next communicative aspect of packaging products is the requirement to "tune" consumers into prolonged communication, to promote interest and willingness to acquire goods. Typically, the implementation of such a requirement is carried out through the introduction of font elements and their clear structuring with the help of a system of decorative planes, so-called "dies". Font alphabets, unlike realistic or photographic images, can most accurately tell about the properties of a product in each of the packaging volumes, explaining to the consumer what to expect from the product. The next project design, which also ensures the implementation of the above requirement, is the original formulation that is executed on the basis of standardized structural elements provided that there is a clear interaction between the constructive and graphic solutions of the packaging products. Consequently, the more noticeable the allocation of packaging in the cell to the same of a similar kind is, the better the process of forming factor is worked out. Of course, informational and communicative elements do not lose their significance in this case, but their design must be logically subordinated to the constructive properties of the form of detection. Conclusions: Tasks for the design of packaging products include the professional use of professional techniques of graphic design that make it possible to implement dualistic-oriented requirements. A specific feature of the use of such techniques is the refusal to follow the compositional schemes and plastic-shaped characteristics of the communicative elements of the already sold packaging products. Instead, resistance rests on the content fulfillment of each of the techniques which allows to implement an individualized approach to each of the projected packaging. The study shows the influence and significance of each of the communicative aspects that are considered in detail through a comprehensive analysis
