We demonstrate QeNoBi, a system for mining and querying customer behavioral patterns. QeNoBi combines an interactive visual interface, on-demand mining, and efficient top-k processing, to provide the exploration of customer behavior over time. QeNoBi relies on two distinct data models: a customer-centric graph that represents customers with similar purchasing behaviors and is annotated with a change algebra to reflect their behavior evolution, and product-centric time series that reflect the evolution of customer purchases over time. Users can query both representations along three dimensions: shape (the sketched trend of the behavior), scope (the set of customers/products of interest), and time granularity. QeNoBi provides a holistic behavior exploration capability by allowing users to seamlessly switch between customer-centric and product-centric views in a coordinated manner, thereby catering to various needs. A demonstration of QeNoBi is available at https://***/2HlcO3S.

In response to the existing university book recommendation systems that mostly recommend readers based on library resources and lack exploration of recommended books, this paper proposes a system service architecture that accurately pushes both readers and libraries simultaneously. The system is designed using technologies such as web spiders, big data, NLP, and visualanalysis. The system integrates reader data entry, web crawler, user profile, book similarity measurement, and intelligent push functions. Book managers can use the system to push books accurately and discover recommended books. The system fully utilizes book attribute data and reader attribute data, avoiding common cold start issues in recommendation systems, and providing support for improving the service level of the library and scientifically allocating collection resources.

A city’s history and culture studies involves understanding the literary works and historical events that have shaped the city’s identity. Increased availability of quantitative historical data has provided new opportunities. Taking Nanjing as an example, this paper proposes EmoGeoCity, a visual analytics system to study a city’s cultural and historical evolution, through the use of digital humanities methods and emotional geography. The system incorporates sentiment analysis into historical research to quantify the emotional content of works and synthesize an overall emotion trend within a specific location. A dynamic emotional map, integrating locations, works, and events, enables a macroscopic observation of city emotions over time. An emotional polyline is designed to provide a microscopic interpretation of the emotion trend of a single location. exploration through the system reveals the evolution of the city from an emotional geographic perspective, which gives insights for humanities researchers studying a city’s history and literature, as well as for the general public interested in gaining knowledge on historical sites. Case and user studies illustrate the effectiveness and usability of our system.

Many literature enthusiasts join communities to discuss their favourite fictional characters and novels, but meaningful insights may be slow to achieve and share when attempting to recall or verify the textual basis of their personal perspectives. Information visualisations can present text-derived data to make its summarisation and exploration both accessible and intuitive, yet visualisations of literary works are mostly tailored to expert workflows. This design study addresses this gap, comprehensively detailing our process of uncovering the tasks, data, and visual design requirements to implement Clover Connections, a visualisation of text-derived data for non-experts. Its layout features clover-shaped glyphs, storylines, and arcs to visually represent and connect temporal, social and personal data on characters in novels, which we demonstrate using datasets built from two popular novels. A formative user evaluation study with non-expert participants showed Clover Connections supports multiple general character analysis tasks, and provided qualitative insights that encourage future work.

This comprehensive review paper explores the state of the art in visual localization and navigation, drawing on the principles and methodologies of three significant deep learning networks: visual Localization Network (VLocNet), Deep Fusion Network (DFNet), and Hybrid Frontend Network (HFNet). Each of these networks demonstrates the application of deep learning to spatial awareness and navigation tasks in unique and significant ways. Rather than an exhaustive dissection of these networks, the paper provides an encompassing overview, illuminating their underlying principles, architectural design, and their relative performance within the field. Additionally, the paper delves into the practical implications of these networks, examining their applications in diverse real-world scenarios. It underlines this examination with a comprehensive analysis of existing literature and experimental results, intended to impart a profound understanding of these networks' strengths, limitations, and potential application areas. Ultimately, this review aims to present a valuable compass to researchers navigating the evolving landscape of advancements in visual localization and navigation, thereby fostering enriched understanding and facilitating future exploration and development in this compelling field.

This paper presents a solution for the autonomous exploration and inspection of Ballast Water Tanks (BWTs) of marine vessels using aerial robots. Ballast tank compartments are critical for a vessel's safety and correspond to confined environments often connected through particularly narrow manholes. The method enables their volumetric exploration combined with visual inspection subject to constraints regarding the viewing distance from a surface. We present evaluation studies in simulation, in a mission consisting of 18 BWT compartments, and in 3 field experiments inside real vessels. The data from one of the experiments is also post-processed to generate semantically-segmented meshes of inspection-important geometries. Geometric models can be associated with onboard camera images for detailed and intuitive analysis.

With the development of the times, the use of 3D image virtual reconstruction (ivR) systems is increasing. The 3D ivR system can solve the problems of poor user experience quality and low human-machine interaction efficiency, so the research significance is very significant. However, nowadays, 3D ivR systems are facing issues of reconstruction accuracy. If this problem can be solved, it can greatly improve the efficiency of the 3D ivR system. Therefore, this article focused on the analysis of a 3D ivR system based on visual communication technology, aiming to improve the reconstruction accuracy of the 3D ivR system through visual communication technology. This article experimentally tested the reconstruction accuracy of a 3D ivR system using visual communication technology, with a maximum accuracy of 74% and a minimum accuracy of 62%. However, traditional 3D ivR systems had a maximum accuracy of 56% and a minimum accuracy of 50%. From this experimental data, it can be inferred that the use of visual communication technology can improve the reconstruction accuracy of 3D ivR systems. This indicated that visual communication technology has achieved good results in 3D ivR systems.

Typically, people perform visualdataanalysis using mouse and touch interactions. While such interactions are often easy to use, they can be inadequate for users to express complex information and may require many steps to complete a task. Recently natural language interaction has emerged as a promising technique for supporting exploration with visualization, as the user can express a complex analytical question more easily. In this paper, we investigate how to synergistically combine language and mouse-based direct manipulations so that weakness of one modality can be complemented by the other. To this end, we have developed a novel system, named Multimodal Interactions System for visualanalysis (MivA), that allows user to provide input using both natural language (e.g., through speech) and direct manipulation (e.g., through mouse or touch) and presents the answer accordingly. To answer the current question in the context of past interactions, the system incorporates previous utterances and direct manipulations made by the user within a finite-state model. We tested the applicability of MivA on several dashboards including a COVID-19 dashboard that visualizes coronavirus cases around the globe. Our demonstration provides initial indication that the MivA system enhances the flow of visualanalysis by enabling fluid, iterative exploration and refinement of data in a dashboard with multiple-coordinated views.
