With the development of the Internet, the amount of information present on the network has grown rapidly, leading to increased difficulty in obtaining effective information. Especially for individuals, enterprises, and institutions with a large amount of information, it is an almost impossible task to integrate and analyze Internet information with great difficulty just by human resources. Internet hot events mining and analysis technology can effectively solve the above problems by alleviating information overload, integrating redundant information, and refining core information. In this paper, we address the above problems and research hot event topic sentence generation techniques in the field of hot event mining and design a hybrid event candidate set construction algorithm based on topic core word mapping and event triad selection. The algorithm uses the PAT-Tree technique to extract high-frequency core words in topic hotspots and maps the high-frequency words into sentences to generate a part of event core sentences. The other part of event core sentences is extracted from the topic hotspots by making event triples as candidate elements, and sentences containing event elements are extracted from the topic hotspots. The sets of event core sentences generated by the two methods are mixed and filtered and sorted to obtain the candidate set, which can be used to build a word graph-based main service channel (MSC) model. In this paper, we also propose an improved word graph-based MSC model and use it for the extraction of event topic sentences. Based on the above research, a hot event analysis system is implemented. The system analyzes the existing topic data and uses the event topic sentence generation algorithm studied in this paper to generate the titles of hot spots, that is, hot events. At the same time, the topics are displayed from different dimensions, and data visualization is completed. The visualization includes the trend change of event hotness, trend change of event sentiment polarity, and distribution of event article sources.

The present study examines a sample of 220 pieces of news related to human evolution, written in Spanish and published over a period of two years, both in digital and print media. The aim of this study is to assess the rigor and coherence of the information in the news in our sample with scientific knowledge on the theory of evolution. To this end, errors and the incorrect use of concepts related to biological evolution are identified, classified according to criteria resulting from the review of previous studies, and finally, the frequency of errors identified in news published in print media is compared with that identified in digital media. The results presented allow us to highlight the significantly high frequency of errors in the news analyzed and the most frequent error categories. Results are discussed within the frame of the important role that scientific journalism plays in the processes of knowledge dissemination, in this case, related to human evolution.

Candidate Set

The antibody candidate set generated by the clonal selection algorithm has only a small number of antibodies with high antigen affinity to obtain high-frequency mutations. Among other antibodies, some low-affinity antibodies are replaced by new antibodies to participate in the next clonal selection. A large number of antibodies with high affinity make it difficult to participate in clonal selection and exist in antibody concentration for a long time. This part of inactive antibody forms a “black hole” of the antibody set, which is difficult to remove and update in a timely manner, thus affecting the speed at which the algorithm approximates the optimal solution. Inspired by the mechanism of biological forgetting, an improved clonal selection algorithm is proposed to solve this problem. It aims to use the abstract mechanism of biological forgetting to eliminate antibodies that cannot actively participate in high-frequency mutations in the antibody candidate set and to improve the problem of insufficient diversity of antibodies in the clonal selection algorithm, which is prone to fall into the local optimal. Compared with the existing clonal selection and genetic algorithms, the experiment and time complexity analysis show that the algorithm has good optimization efficiency and stability.

The Impact

Purpose – At present no frameworks exist for services marketers to incorporate social media (SM) within marketing communications planning. The majority of integrated marketing communications (IMC) frameworks were developed prior to the development of the widespread use of digital and SM for information seeking, sales and service. The purpose of this paper is to investigate this issue for services marketers specifically as they differ from FMCG, industrial and durable marketers in terms of marketing messages, branding, media and channels. Furthermore, as they are less reliant on outsourced sale channels they have more potential than other industries to integrate social and digital media to build awareness, brands and sales. Design/methodology/approach – Depth interviews were conducted with eight senior services marketing executives to identify the impact of SM on marketing communications planning, implementation and measurement. Findings – The findings revealed that the unique characteristics of SM (such as interactivity and individualisation, integration of communication and distribution channels, immediacy and information collection) impact traditional marketing communications frameworks. These impacts manifested in 12 modifications specific to services and SM to traditional generic IMC frameworks encompassed by the themes of reach, service channel, word-of-mouth advocacy, consumer generated messages, listening and behavioural measurement. Practical implications – The rapidly evolving nature of SM means senior services marketers need to educate organisational stakeholders regarding implementation issues, which may be a barrier to effective integration of SM within marketing communications. Originality/value – With digital marketing communications budgets reaching 30 per cent within some organisations, it is timely to put forward a marketing communication decision-making framework that first incorporates SM and second is suitable for services marketers.

The ground resolved distance (GRD) of an imaging sensor, i.e. the size of the smallest element distinguishable on acquired imagery, is one of the most important sensor quality assessment factors, as it is directly linked to the amount of information that can be derived from the end product. The paper is a review of a wide variety of calibration targets used for determining the spatial resolution of remote sensing sensors. The author provides a description of calibration targets used historically and then moves on to high-frequency targets used for high-resolution remote sensing imaging equipment. As analysis is made which of these types of targets are best suited for UAV sensors, taking into account parameters very specific to UAVs: frame size, small GSD values and low flight stability.

The progress and popularization of the mobile Internet herald the age of Internet plus education. With the deepening of education reform, China raises new requirements on the key competencies of students. Focusing on the cultivation of these competencies, this paper develops an innovative method for digital media education based on mobile Internet technology. After surveying the current learning state of students majoring in digital media, the authors proposed a blended teaching model with digital media based on mobile Internet technology. There are four parts of the model, namely, frontend analysis, online autonomous learning, offline teaching, and after-class online evaluation. The design of each part was described in details. Then, the proposed model was applied to the Poster Design course of digital media major. Comparative analysis shows that the model promotes students’ learning efficiency, and their key competencies, and receives high recognition from the students. This research provides new impetus to the innovation of digital media education based on mobile Internet technology.

Purpose – This paper aims to examine the factors that can predict citizen-initiated contact with e-government as an attempt to identify important differences between service channel selections. Although more than two decades have passed since the initiation of e-government, digital channel choice is still being questioned, compared to traditional channels, and the level of selection with channels is being investigated. Design/methodology/approach – This study states three research questions that are answered through a literature review and statistical analysis of a survey in a developed country. More specifically, it identifies the factors that impact channel choice and validates them with survey results. To this end, this paper utilizes data from a national Canadian survey, where citizens empirically evaluated their channel choice – e-government, new digital media and traditional service channels – for government contacts. Findings – Statistical analysis over this data return valuable findings such as that the e-government channel is more appropriate for information collection, whereas traditional service channels are more likely to establish individual problem solving. Moreover, the digital divide appears to have an impact on citizen channel choice. Furthermore, digitally literate citizens who are aware of privacy issues are more likely to use new digital media. Finally, citizens are quite satisfied from their new digital media experience, but are not as satisfied with their traditional contact experience. Originality/value – These outcomes show that e-government obstacles regarding digital divide, trust and efficiency remain active and have to be addressed more carefully by governments. This study shows that e-government and new digital media are not simple channel choices, but are complex in public service delivery. These outcomes confirm the significance of channel choice for transforming government, as e-government appears to be a part of a broader channel choice agenda.

Usage Context

Nowadays travel and tourism Web sites store and offer a large volume of travel related information and services. Furthermore, this huge amount of information can be easily accessed using mobile devices, such as a phone with mobile Internet connection capability. However, this information can easily overwhelm a user because of the large number of information items to be shown and the limited screen size in the mobile device. Recommender systems (RSs) are often used in conjunction with Web tools to effectively help users in accessing this overwhelming amount of information. These recommender systems can support the user in making a decision even when specific knowledge necessary to autonomously evaluate the offerings is not available. Recommender systems cope with the information overload problem by providing a user with personalized recommendations (i.e., a well chosen selection of the items contained in the repository), adapting this selection to the user’s needs and preferences in a particular usage context. In this chapter, the authors present a recommendation approach integrating a conversational preference acquisition technology based on “critiquing” with map visualization technologies to build a new map-based conversational mobile RS that can effectively and intuitively support travelers in finding their desired products and services. The results of the authors’ real-user study show that integrating map-based visualization and critiquing-based interaction in mobile RSs improves the system’s recommendation effectiveness, and increases the user satisfaction.
