  • Jingjing Zhang,Xiaodan Lou,H. Zhang, Jiang Zhang: Modeling collective attention in online and flexible learning environments; Distance Education 40:3, pages 303-308., [download]
  • Understanding how collective attention flow circulates amid an over-abundance of knowledge is a key to designing new and better forms of online and flexible learning experiences. This study adopted an open flow network model and the associated distance metrics to gain an understanding of collective attention flow using clickstream data in a massive open online course. Various patterns and dynamics of attention flow were identified and are discussed here in relation to learning performance. The results show that the effective accumulation, circulation, and dissipation of attention flow are important contributors to academic attainment. Understanding the patterns and dynamics of attention flow will allow us to design cost-effective learning resources to prevent learners from becoming overloaded.

  • 城市自其出现以来,已然成为人类发展的重要驱动,目前全球有超过50%的人口居住在城市之中,超过80%的财富与90%的创新都产生于城市;但城市的发展同时也带来许多社会问题,例如污染、交通拥堵、各类犯罪等等。城市是典型的由多种元素构成的复杂系统,过去的研究往往只关注于城市的某一方面,而且目前对于城市的定量研究仍不够充分,难以定量预测城市中主要元素的空间分布(例如人口、道路、与社会经济相关的相互作用等等)。本文基于空间吸引和匹配生长机制提出了一个简单模型,首次揭示了城市中主要元素的空间标度律,而且各主要元素可以由统一的框架来解释,而这使得我们可以使用任何单一的分布来对其他的分布进行推断。此外文中提出的模型不但可以解释介观尺度的空间分布,还可以对跨城市的宏观超线性与亚线性标度律的起源作出一般性解释,并准确预测公里级的社会经济活动。而且我们的理论方法也突破了过去城市研究领域中全局平均场理论的假设,直接从增长演化的视角对城市进行建模。文章还提出一些全新的概念,例如活跃人口,这一概念可以解决过去对于人口分布形式究竟是指数还是幂律的部分争论,还可应用于城市街区安全评估。简言之,我们的工作提出了揭示城市元素间相互作用与演变的新视角和新方法,未来它将有广泛的应用场景。

  • Gu, Weiwei, Li Gong,Xiaodan Lou, Jiang Zhang: The Hidden Flow Structure and Metric Space of Network Embedding Algorithms Based on Random Walks; Scientific Reports, 7: 13114 , [download]
  • Network embedding which encodes all vertices in a network as a set of numerical vectors in accordance with it’s local and global structures, has drawn widespread attention. Network embedding not only learns significant features of a network, such as the clustering and linking prediction but also learns the latent vector representation of the nodes which provides theoretical support for a variety of applications, such as visualization, link prediction, node classification, and recommendation. As the latest progress of the research, several algorithms based on random walks have been devised.
    Although those algorithms have drawn much attention for their high scores in learning efficiency and accuracy, there is still a lack of theoretical explanation, and the transparency of those algorithms has been doubted. Here, we propose an approach based on the open-flow network model to reveal the underlying flow structure and its hidden metric space of different random walk strategies on networks. We show that the essence of embedding based on random walks is the latent metric structure defined on the open-flow network. This not only deepens our understanding of random- walk-based embedding algorithms but also helps in finding new potential applications in network embedding.

  • Lei Dong,Ruiqi Li,Jiang Zhang, Zengru Di: Population-weighted efficiency in transportation networks; Scientific Reports, 6: 26377, 2016, [download]
  • Transportation efficiency is critical for the operation of cities and is attracting great attention worldwide. Improving the transportation efficiency can not only decrease energy consumption, reduce carbon emissions, but also accelerate people’s interactions, which will become more and more important for sustainable urban living. Generally, traffic conditions in less-developed countries are not so good due to the undeveloped economy and road networks, while this issue is rarely studied before, because traditional survey data in these areas are scarce. Nowadays, with the development of ubiquitous mobile phone data, we can explore the transportation efficiency in a new way. In this paper, based on users’ call detailed records (CDRs), we propose an indicator named population-weighted efficiency (PWE) to quantitatively measure the efficiency of the transportation networks. PWE can provide insights into transportation infrastructure development, according to which we identify dozens of inefficient routes at both the intra- and inter-city levels, which are verified by several ongoing construction projects in Senegal. In addition, we compare PWE with excess commuting indices, and the fitting result of PWE is better than excess commuting index, which also proves the validity of our method.

  • Peiteng Shi,Xiaohan Huang,Jun Wang, Jiang Zhang: A Geometric Representation of Collective Attention Flows; PLoS ONE 10(9): e0136243, 2015, [download]
  • With the fast development of Internet and WWW, “information overload” has become an overwhelming problem, and collective attention of users will play a more important role nowadays. As a result, knowing how collective attention distributes and flows among different websites is the first step to understand the underlying dynamics of attention on WWW. In this paper, we propose a method to embed a large number of web sites into a high dimensional Euclidean space according to the novel concept of flow distance, which both considers connection topology between sites and collective click behaviors of users. With this geometric representation, we visualize the attention flow in the data set of Indiana university clickstream over one day. It turns out that all the websites can be embedded into a 20 dimensional ball, in which, close sites are always visited by users sequentially. The distributions of websites, attention flows, and dissipations can be divided into three spherical crowns (core, interim, and periphery). 20% popular sites (Google.com, Myspace.com, Facebook.com, etc.) attracting 75% attention flows with only 55% dissipations (log off users) locate in the central layer with the radius 4.1. While 60% sites attracting only about 22% traffics with almost 38% dissipations locate in the middle area with radius between 4.1 and 6.3. Other 20% sites are far from the central area. All the cumulative distributions of variables can be well fitted by “S”-shaped curves. And the patterns are stable across different periods. Thus, the overall distribution and the dynamics of collective attention on websites can be well exhibited by this geometric representation.

  • In many networked systems (cities, online communities), links (or interactions) grow faster than nodes, as well, the diversity of nodes grow slower than nodes. We build a simple random network model based on geometric matching mechanism to reproduce both phenomena. The extensive model is further applied to model the distribution of natural cities.

  • Open flow network is a special weighted directed graph in which weighted links are flows, and the flows are in balance.

  • As a result of the international division of labor, the trade value distribution on different products substantiated by international trade flows can be regarded as one country’s strategy for competition. Each country wants to diversify their investments on different products as well as make profits as possible as they can. We build a model based on maximum entropy principle to reproduce the distribution curves of countries. The results show that almost all countries' export share distributions can be explained by the maximum entropy model if the constraints are properly selected.

  • Lingfei Wu,Jiang Zhang,Min Zhao: The Metabolism and Growth of Web Forums; PLoS ONE 2014, 9(8): e102646, [download]
  • We view web forums as virtual living organisms feeding on user's clicks and investigate how they grow at the expense of clickstreams. We find that (the number of page views in a given time period) and (the number of unique visitors in the time period) of the studied forums satisfy the law of the allometric growth, i.e., . We construct clickstream networks and explain the observed temporal dynamics of networks by the interactions between nodes. We describe the transportation of clickstreams using the function , in which is the total amount of clickstreams passing through node and is the amount of the clickstreams dissipated from to the environment. It turns out that , an indicator for the efficiency of network dissipation, not only negatively correlates with , but also sets the bounds for . In particular, when and when . Our findings have practical consequences. For example, can be used as a measure of the “stickiness” of forums, which quantifies the stable ability of forums to remain users “lock-in” on the forum. Meanwhile, the correlation between and provides a method to predict the long-term “stickiness” of forums from the clickstream data in a short time period. Finally, we discuss a random walk model that replicates both of the allometric growth and the dissipation function.

  • Peiteng Shi,Jiang Zhang,Bo Yang, Jingfei Luo: Hierarchicality of Trade Flow Networks Reveals Complexity of Products; PLoS ONE 2014, 9(6): e98247, [download]
  • With globalization, countries are more connected than before by trading flows, which amounts to at least 36 trillion dollars today. Interestingly, around 30-60 percents of exports consist of intermediate products in global. Therefore, the trade flow network of particular product with high added values can be regarded as value chains. The problem is weather we can discriminate between these products from their unique flow network structure? This paper applies the flow analysis method developed in ecology to 638 trading flow networks of different products. We claim that the allometric scaling exponent \eta can be used to characterize the degree of hierarchicality of a flow network, i.e., whether the trading products flow on long hierarchical chains. Then, it is pointed out that the flow networks of products with higher added values and complexity like machinary, transport equipment etc. have larger exponents, meaning that their trade flow networks are more hierarchical. As a result, without the extra data like global input-output table, we can identify the product categories with higher complexity, and the relative importance of a country in the global value chain by the trading network solely.

  • Hongmei Lei,Jiang Zhang: Capabilities’ substitutability and the “S” curve of export diversity; EPL 105 (2014) 68003, [download]
  • Product diversity, which is highly important in economic systems, has been high-
    lighted by recent studies on international trade. We found an empirical pattern, designated as “S-shaped curve”, that models the relationship between economic size (logarithmic GDP) and export diversity (the number of varieties of export products) on the detailed international trade data. As the economic size of a country begins to increase, its export diversity initially increases in an exponential manner, but overtime, this diversity growth slows and eventually reaches an upper limit. The interdependence between size and diversity takes the shape of an S-shaped curve that can be fitted by a logistic equation. To explain this phenomenon, we introduce a parameter called “substitutability” into the list of capabilities or factors of products in the tri-partite network model (i.e., the country-capability-product model) of Hidalgo et al. As we observe, when the substitutability is zero, the model returns to Hidalgo’s original model but failed to reproduce the S-shaped curve. However, in a plot of data, the data increasingly resembles an S-shaped curve as the substitutability expands. Therefore, the diversity ceiling effect can be explained by the substitutability of different capabilities.

  • All countries in the world are connected with each other and one country's export may impact other countries deeply through global value chains as the development of globalization. Owing to the regional differences in culture and resources, some countries may dominate the producing and exporting of one product in the global trade. This paper treats international trade webs of different products as flow networks to reveal a power law relationship between the goods flow through a country i (Ai) and the power impact of i to other countries (Ci) in the trade network of a specific product, Ci~Ai^\eta . Where the exponent \eta can be used to reflect the degree of the impact concentration on high through flow nodes of the whole network, it is centralized or decentralized. We discover that most of trade networks are centralized (i.e., \eta>1) and the manufacture products with high added values such as machinery equipment, iron and chemical products have larger exponent, i.e., their trade networks are more centralized than the ones of the primary products like agricultural and raw materials. This also means that the flow structure of the former is more centralized than the latter.

  • Jiang Zhang,Tongkui Yu: Allometric Scaling of Countries; Physica A Vol.389(2): 4887-4896(2010), [download]
  • As huge complex systems consisting of geographic regions, natural resources, people and economic entities, countries follow the allometric scaling law which is ubiquitous in ecological, urban systems. We systematically investigated the allometric scaling relationships between a large number of macroscopic properties and geographic (area), demographic (population) and economic (GDP, gross domestic production) sizes of countries respectively. We found that most of the economic, trade, energy consumption, communication related properties have significant super-linear (the exponent is larger than 1) or nearly linear allometric scaling relations with GDP. Meanwhile, the geographic (arable area, natural resources, etc.), demographic(labor force, military age population, etc.) and transportation-related properties (road length, airports) have significant and sub-linear (the exponent is smaller than 1) allometric scaling relations with area. Several differences of power law relations with respect to population between countries and cities were pointed out. Firstly, population increases sub-linearly with area in countries. Secondly, GDP increases linearly in countries but not super-linearly as in cities. Finally, electricity or oil consumptions per capita increases with population faster than cities.

  • Jiang Zhang,Liangpeng Guo: Scaling Behaviors of Weighted Food Webs as Energy Transportation Networks; Journal of Theoretical Biology 264 (2010) 760–770, [download]
  • Food webs can be regarded as energy transporting networks in which the weight of each edge denotes the energy flux between two species. By investigating 21 empirical weighted food webs as energy flow networks, we found several ubiquitous scaling behaviors. Two random variables Ai and Ci defined for each vertex i, representing the total flux (also called vertex intensity) and total indirect effect or energy store of i, were found to follow power law distributions with the exponents \alpha=1.32 and \beta=1.33, respectively. Another scaling behavior is the power law relationship, Ci~Ai^{\eta}, where \eta=1.02. This is known as the allometric scaling power law relationship because Ai can be treated as metabolism and Ci as the body mass of the subnetwork rooted from the vertex i, according to the algorithm presented in this paper. Finally, a simple relationship among these power law exponents, \eta =(\alpha−1)/(\beta−1), was mathematically derived and tested by the empirical food webs.

  • Jiang Zhang: Energy Flows in Complex Ecological Systems: A Review; Journal of Systems Science and Complexity 2009 22 (3): 345-359, [download]
  • Energy flow drives the complex systems to evolve. The allometric scaling as the universal
    energy flow pattern has been found in different scales of ecological systems. It reflects the general power law relationship between flow and store. The underlying mechanisms of energy flow patterns are explained as the branching transportation networks which can be regarded as the result of systematic optimization of a biological target under constraints. Energy flows in the ecological system may be modelled by the food web model and population dynamics on the network. This paper reviews the latest progress on the energy flow patterns, explanatory models for the allometric scaling and modelling approach of flow and network evolution dynamics in ecology. Furthermore, the possibility of generalizing these flow patterns, modelling approaches to other complex systems is discussed.

  • An ecosystem can be viewed as an energy flow system in which various species are connected by energy flows along food web links. To understand the co-evolution of the fast dynamics of energy flows and slow dynamics of food web
    structure, a simple reaction diffusion equation is presented in this paper. Some statistical indicators such as total system throughflow (TST) and Shannon entropy are designed to describe the macro-level evolution of the system. The
    positive correlation between time series of TST and Shannon entropy is mainly shown. That means the diversity of the species may accelerate the total energy flows in the system. This conclusion may help us to understand general phenomena of flows and diversity in other complex systems.

  • Allometric scaling is an important universal property of metabolic living systems. It also describes the self-similar branching tree-liked structures in transportation networks. This paper presented a new approach to calculate the allometric scaling power law relations for arbitrary flow networks. This method can not only avoid the shortcoming of losing lots of information in the process of generating spanning trees in the conventional approaches but also can be applied to arbitrary weighted networks. The allometric scaling properties of 20 empirical weighted food webs (weights are energy fluxes) are computed according to the new approach, the power law relationships are derived
    with the universal exponent \eta = 1.0298 which reflects the transportation efficiency of the food webs.

  • Jiang Zhang: Complexity and Universality of Iterated Finite Automata; Journal of Complex Systems, 2008,18(1): 145-158, [download]
  • Iterated Finite Automaton (IFA) is invented by Wolfram for studying the conventional Finite State Automata(FSA) by means of A New Kind of Science (NKS) methodology. An IFA is a composition of a finite state automaton and a tape with limited cells. The complexity of behaviors generated by various FSA operating on different tapes can be visualized by two dimensional patterns. Through enumerating all possible 2-state and 3-color IFA, this paper shows that there are a variety of complex behaviors in these simple computational systems. These patterns can be divided into 8 classes roughly such as regular
    patterns, noisy structures, complex behaviors, and so forth. Also they show the similarity between iterated finite automata and elementary cellular automata. Furthermore, any cellular automaton can be emulated by an IFA and vice versa. That means IFA supports universal computation.
