Transparent Aspect-Level Sentiment Analysis Based on Dependency Syntax Analysis and Its Application on COVID-19

Aspect-level sentiment analysis identifies fine-grained emotion for target words. There are three major issues in current models of aspect-level sentiment analysis. First, few models consider the natural language semantic characteristics of the texts. Second, many models consider the location characteristics of the target words, but ignore the relationships among the target words and among the overall sentences. Third, many models lack transparency in data collection, data processing, and results generating in sentiment analysis. In order to resolve these issues, we propose an aspect-level sentiment analysis model that combines a bidirectional Long Short-Term Memory (LSTM) network and a Graph Convolutional Network (GCN) based on Dependency syntax analysis (Bi-LSTM-DGCN). Our model integrates the dependency syntax analysis of the texts, and explicitly considers the natural language semantic characteristics of the texts. It further fuses the target words and overall sentences. Extensive experiments are conducted on four benchmark datasets, i.e., Restaurant14, Laptop, Restaurant16, and Twitter. The experimental results demonstrate that our model outperforms other models like Target-Dependent LSTM (TD-LSTM), Attention-based LSTM with Aspect Embedding (ATAE-LSTM), LSTM+SynATT+TarRep and Convolution over a Dependency Tree (CDT). Our model is further applied to aspect-level sentiment analysis on “government” and “lockdown” of 1,658,250 tweets about “#COVID-19” that we collected from March 1, 2020 to July 1, 2020. The experimental results show that Twitter users’ positive and negative sentiments fluctuated over time. Through the transparency analysis in data collection, data processing, and results generating, we discuss the reasons for the evolution of users’ emotions over time based on the tweets and on our models.

COLLOCATION OF ENGLISH, ARABIC, AND INDONESIAN COVID-19 TERMS

This paper studies language and translation of the term related to Covid-19. The background of this research is many new vocabularies related to Covid-19 is borrowing term. This study attempts to find answers to the following question: a) What kind of collocations are related to the term Covid-19 pandemic in English, Arabic, and Indonesian? b) How is the pattern of word order forming collocations with the term Covid-19 pandemic in English, Arabic, and Indonesian? This study addressed the emergence of new English, Arabic, Indonesian collocation related to Covid-19 using H. Men’s collocation theory. This study used newspapers, namely Republika, BBC, al-Jazeera online that show Covid-19 as the standard procedure for collecting data. This study used corpus linguistic to analyze collocation, concordance, and syntax analysis, models. The Covid-19 domain has chosen because the Indonesian term in this domain uses a lot of loanwords. The source of the data was a basic-words and compound term. The investigation informed several aspects of findings, such as identifying the pattern of collocation, borrowing, and collocation term of coronavirus concept.

Evaluation and Optimization of Walkability of Children’s School Travel Road for Accessibility and Safety Improvement

(1) Background: In the context of a children friendly city, accessibility and safety are the basic needs of children’s pedestrian school travel. This study proposes a comprehensive evaluation method of pedestrian accessibility and safety for children’s school travel. (2) Methods: Firstly, the school travel network was constructed by simulating the path of children walking to school. Secondly, from the meso and micro dimensions, the impact factors of pedestrian accessibility and safety were combed out, and an evaluation index system was constructed. Finally, pedestrian accessibility and safety were evaluated based on the Space Syntax analysis and ArcGIS spatial analysis, and the results were superimposed and spatially differentiated. The new evaluation method was tested in the Jintang Road area in Hedong District, Tianjin, China. (3) Results: The pedestrian accessibility and safety of children’s school travel road in the study area needed to be improved. It was found that the main impact factors were the effective walking width, the spatial connectivity, the visual integration, the obstruction of pedestrian safety, the completeness of crossing facilities and the influence of traffic flow and put forward optimization strategies. After optimized simulation verification, the overall improvement was achieved. (4) Conclusion: The evaluation method is helpful to calculate the pedestrian accessibility and safety of children’s school travel, and help decision makers determine the design and management strategies of child-friendly streets.

Space-time mapping of co-working spaces in Cairo: shifting paradigms from openness to technologically controlled spaces

The paper demonstrates how co-working spaces, with their openness ideologies that are not only manifested in sharing space, but also sharing knowledge and generating access to nonhierarchical productive opportunities, are being subsumed into reinforcing neoliberal exclusiveness. The paper questions the openness of co-working spaces that reconciled with the dominant ideologies of 2011 Cairo, setting the stage to the mushrooming of co-working spaces inside Cairo’s apartment buildings as zones of relative freedom. Through space-time mapping of the emergence of co-working spaces in Cairo, in addition to interviews with co-workers, co-founders, and managers of co-working spaces, the spatial appropriation and accessibility of co-working spaces are demonstrated. Using content analysis and space syntax analysis, the study differentiates between two paradigmatic shifts in the spatial appropriation of co-working spaces—from democratizing digital infrastructure in the aftermath of 2011, to being subsumed by technological capitalist ventures by the end of 2015 into a closed paradigm, they originally emerged to defy—and compares between the spatial accessibility, visual accessibility, and social diversity of the two waves of co-working spaces. Using Cairo’s co-working spaces as a case study, this paper shows how ideologies of openness “neutral” as they may seem, can serve to legitimize exclusiveness, emphasizing how ideas—as men—can be socially located, and serve to legitimize a particular social situation.

Megarons and Minoan Hall Systems: A Comparison of the Large Hall Systems in Minoan and Mycenaean Architecture

<p>Scholarship comparing the Minoan Hall System with the Mycenaean ‘megaron’ has in general emphasized either the similarities or differences between the two types of suite. Early archaeological literature tends to equate the two suites, with scholars such as Joseph Hazzidakis (Hazzidakis 1934:16-17) suggesting that the differences between the two can be explained by differences in climate between Crete and mainland Greece. On the other hand, in more recent scholarship, the two forms are distanced from one another, in effect polarizing the two architectural forms. Comparisons such as these tend to imply that the form of both types of hall system is very regular, with each suite likely hosting the same function as the next. In order to study the similarities and differences between the Minoan Hall System and Mycenaean ‘megaron’, 27 Minoan hall systems and 15 megaron-units have been analysed and compared. These hall systems will be compared in their form, in the way they were incorporated into the surrounding building, and in the features they incorporate. To discuss how the hall systems were incorporated into buildings, Space Syntax Analysis will be used alongside a typology of access and circulation developed by Miriam Clinton (2013) for Minoan architecture. The climate-controlling features of open-air spaces, pier and door partitions and hearths will also be discussed. A close examination of a wide variety of Minoan Hall Systems and Mycenaean ‘megarons’ shows that both forms differed considerably from site to site. Within each architectural form are examples of vastly different sizes, which are incorporated into buildings in very different ways. It is likely, therefore, that these buildings would have functioned in different ways. With this wide variation, it is unsurprising, therefore, that in comparison while some Minoan Hall Systems and Mycenaean ‘megarons’ are very different, others are very similar. It is likely that the functions of some of these more standard hall systems may have overlapped. An examination of the climate-controlling features of open-air spaces, pier and door partitions and hearths reveals that Minoan Hall Systems and Mycenaean ‘megarons’ likely did not differ primarily based on differences in climate. Though these features would have certainly been used for climate control, it will be shown that they likely had some other significance. Finally, from this comparison some tentative and broad conclusions about the possible functions of the two types of hall system have been drawn.</p>

Evaluating Experiential Qualities of Historical Streets in Nanxun Canal Town through a Space Syntax Approach

Many studies have been conducted to measure the experiential qualities of historical streets using the standards and principles released by many global organizations. However, little attention has been paid to the effect of spatial characteristics of historical heritage. This study proposes a space syntax-based methodology, first developed by Bill Hillier and Julienne Hanson with colleagues from the Bartlett School of Architecture, while introducing factors such as complexity, coherence, ‘mystery’, and legibility from the work of environmental psychologist Stephen Kaplan and the urban designer Gordon Cullen. Our intention is to help inform urban designers in understanding people’s spatial cognition of historical streets, and thereby assist designers and managers in identifying where cognitive experiences can be improved. The proposed method is applied to Nanxun, which is a developed canal town currently in decline in Zhejiang Province, China. This will be treated as the case study in order to explore the implication of the space syntax analysis. The impact from spatial characteristics on the evaluation is indirect and largely determined by the road-network of the canal town. As for Nanxun, the findings of this research suggest that the government’s priority is to solve current negative tourist perception based on a conservation restoration plan. The findings of this research provide a reference for policymakers to better understand the experiential qualities of historical streets in townscapes.

The Continuous Learning Cycle: A Multi-phase Post-occupancy Evaluation (POE) of Decentralized Nursing Unit Design

Purpose: This study aims to demonstrate how multiphase postoccupancy evaluation (POE) research was integrated into multiple projects to develop a continuous learning cycle. Background: Despite the well-recognized importance of POE, few studies have reported how knowledge from POE is applied in new designs. Method: This study is developed as a multiphase POE that spanned 3 years and across three units. Phase I POE compared an existing unit (Unit A) in Hospital A and a new Unit B in Hospital B that has implemented innovative design features such as decentralized nurse stations. The idea was to understand the challenges of the existing facility in Hospital A and gather lessons learned from the new design in Unit B to inform the design of the Hospital A expansion (Unit C). After the new expansion was occupied, the Phase II POE was conducted using the same set of POE tools in both Unit C and Unit A. The POE applied the following methods: (1) patient room evaluations using the Center for Health Design standardized POE tools, (2) space syntax analysis of visibility, and (3) a pre- and postmove analysis of Press Ganey data. Results: The results demonstrated that by incorporating lessons learned from the Phase I POE, Unit C has further improvement on patient room design ratings, improved patient satisfaction, and better visibility among nurse work areas compared to Unit A and Unit B. Conclusions: The multiphase, multisite POE with standardized tools has demonstrated its value as an important tool for continuous design quality improvement.

Abnormalities in Resting-State EEG Microstates are a Vulnerability Marker of Migraine

Background: Resting-state EEG microstates are thought to reflect brief activations of several interacting components of resting-state brain networks. Surprisingly, we still know little about the role of these microstates in migraine. In the present study, we attempted to address this issue by examining EEG microstates in patients with migraine without aura (MwoA) during the interictal period and comparing them with those of a group of healthy controls (HC). Methods: Resting-state EEG was recorded in 61 MwoA patients (50 females) and 66 HC (50 females). Microstate parameters were compared between the two groups. We computed four widely identified canonical microstate classes A-D.Results: Microstate classes B and D displayed higher time coverage and occurrence in the MwoA patient group than in the HC group, while microstate class C exhibited significantly lower time coverage and occurence in the MwoA patient group. Meanwhile, the mean duration of microstate class C was significantly shorter in the MwoA patient group than in the HC group. Moreover, among the MwoA patient group, the duration of microstate class C correlated negatively with clinical measures of headache‐related disability as assessed by the six-item Headache Impact Test (HIT-6). Finally, microstate syntax analysis showed significant differences in transition probabilities between the two groups, primarily involving microstate classes B, C and D. Conclusions: By exploring EEG microstate characteristics at baseline we were able to explore the neurobiological mechanisms underlying altered cortical excitability and aberrant sensory, affective and cognitive processing, thus deepening our understanding of migraine pathophysiology.

Structural features of the streetscape of Macau across four different spatial scales based on historical maps

In the analysis of complex historical layering, studies on how to avoid theoretical analysis and use quantitative methods of display and analysis are scarce. Therefore, we used space syntax to fill this gap in historical layering analysis. We established a spatial digital model by combining the urban historical landscape theory with the space syntax analysis method. Then, we quantitatively analysed the streetscapes in the four historical periods of Macau and the value-related development of the city’s economy, society, and culture. To this end, we used the theory of urban historical landscape to interpret the streetscape of Macau. We reviewed urban development under different spatial scales, which represent different states of historical layering. Changing ideological trends of construction have induced changes in the city, which have led to changes in the city style. The analysis considers the dimensions of space and time, and its results can guide the continued benign growth of the urban landscape and solve protection problems in practice. Meanwhile, the results of this work also indicate that the unique streetscape of Macau bred by the development of the city does not affect the newly constructed roads. The newly reclaimed areas and the streetscape of the new city are on the verge of homogeneity and cannot reflect the unique regional characteristics of Macau. Therefore, we used the historical map of Macau as a carrier, used space syntax to analyse the structure of Macau’s streetscape, and explored the apparent characteristics and value associations carried by the streetscape of Macau under different historical slices. Our results can help retrieve the value of Macau’s historical streetscape and devise a targeted protection strategy that can help pass on the historical streetscape of Macau to posterity.
