In the first one, nowadays called Web 2.0, people collaborate and enrich data together in a shared information space. In the second part, exchanges extend to computers, resulting in a “Semantic Web” (Berners-Lee 1999). Most historical studies of World Wide Web begin with the American roots of the Internet in ARPANET or follow a historiographical line of post war information revolutionaries, from Vannevar Bush to Tim Berners-Lee. This paper follows an alternative line. At the end of the nineteenth and in the first decades of the twentieth century various European scholars, like Patrick Geddes, Paul Otlet, Otto Neurath, Wilhelm Ostwald explored the organisation, enrichment and dissemination of knowledge on a global level to come to a peaceful, universal society. We focus on Paul Otlet (1868-1944) who developed a knowledge infrastructure to update information mechanically and manually in collaboratories of scholars. First the Understanding Infrastructure (2007) report, that Paul N. Edwards et al. wrote on behalf of NSF, will be used to position Otlet’s knowledge organization in their sketched development from information systems to information networks or webs. Secondly, the relevance of Otlet’s knowledge infrastructure will be assessed for Web 2.0 and Semantic Web applications for research. The hypothesis will be put forward that the instruments and protocols envisioned by Otlet to enhance collaborative knowledge production, can still be relevant for current conceptualizations of “scientific authority” in data sharing and annotation in Web 2.0 applications and the modeling of the Semantic Web. http://www.slis.indiana.edu/media/net_sci_2009/ncs_05_26.mp3 Thu, 04 Jun 2009 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2009/ncs_04_06.mp3 Creative Commons Attribution 3.0 United States - Networks and Complex Systems Spring 2009 (audio): An increasing fraction of human interactions are digitally captured. These digital breadcrumbs, combined with substantial computational power, create enormous opportunities for ground breaking science. This talk will discuss what some of the potential opportunities are for developing an improved understanding of collective human behavior, as well the potential barriers to the emergence of a "computational social science." In particular, the objective of this talk will be to spur discussion regarding how to bridge the gap between various methods for data mining and enhancing understanding of human behavior. http://www.slis.indiana.edu/media/net_sci_2009/ncs_04_06.mp3 Thu, 04 Jun 2009 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2009/ncs_04_27.mp3 Creative Commons Attribution 3.0 United States - Networks and Complex Systems Spring 2009 (audio): Our current understanding of networks structure and evolution is largely based on the description of the dynamical processes that have shaped them.

Web mining - i.e. the application of data mining techniques to extract knowledge from Web content, structure, and usage - is the collection of technologies to fulfill this potential. Interest in Web mining has grown rapidly in its short existence, both in the research and practitioner communities. This talk provides an overview of the accomplishments of the field - both in terms of technologies and applications - and outlines key future research directions. http://www.slis.indiana.edu/media/net_sci_2009/ncs_04_13.mp3 Mon, 04 May 2009 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2009/ncs_04_06.mp3 Creative Commons Attribution 3.0 United States - Networks and Complex Systems Spring 2009 (audio): The human brain is a complex network. My talk will be about emerging links between the connectivity structure of the brain and its functional dynamics, and about how we might construct a computational network model of the brain. We now know that structural brain networks exhibit a number of topological features, including small-world attributes, modularity, and hubs. How do these structural features relate to functional characteristics of brain networks, to their dynamic patterns, to their processing power, robustness, or capacity to support flexible behavior? I will review recent work on complex brain networks that aims to identify how brain networks are organized and how they process and integrate information. I will also outline how these efforts may inform the design of a comprehensive structural and dynamic model of the human brain. http://www.slis.indiana.edu/media/net_sci_2009/ncs_04_06.mp3 Thu, 04 Jun 2009 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/kaser/kaser09_richardson.mov - David Kaser Lecture Series (video): From Hand Printer to Ecological Informatician: Or, How I Discovered the Lost Ship of the Colorado Desert" — an autobiographical speculation on how the field has changed over my thirty plus year career with advice on focusing on the present, studying the past, and planning for the future..."

But an earlier "downloading crisis" occurred in the 1980’s when users, newly equipped with personal computers began to download data from commercial databases like DIALOG and Chemical Abstracts. Database vendors feared that downloading of citations would undermine their revenues and they initially forbade downloading, employing the rhetoric of piracy and economic harm common in today’s intellectual property disputes. But, also similar to today, some users continued to download despite vendor protests. What led to a change in database vendors' attitudes toward downloading between 1980 and the mid-1990s? This talk focuses on change in use regimes associated with one type of digital intellectual property: scholarly bibliographical citations. Use Regimes are an analytical tool to analyze changes in who can access intellectual or cultural property and what they can do with it. Analyzing changes in past regimes helps us better understand contemporary debates about what counts as legitimate and illegitimate uses of intellectual and cultural property, the potential effects of access and use restrictions on knowledge and cultural production, and the circumstances important to facilitate change in access and use rules. http://www.slis.indiana.edu/media/rkcsi_2009/rkcsi_03_27.mov Thu, 09 Apr 2009 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2009/ncs_03_23.mp3 Creative Commons Attribution-Noncommercial-No Derivative Works 3.0 United States - Networks and Complex Systems Spring 2009 (audio): The presentation will discuss the various projects of the Cyberinfrastructure for Network Science Center, demonstrating recent developments in the Network Workbench tool, as well as describing some of our future work: the EpiC and SciPolicy cyberinfrastructure projects. Network Workbench helps network scientists process, analyze, and visualize network data. It is highly-extensible, allowing users to contribute their own algorithms to the tool, which are able to interact seemlessly with existing Network Workbench functionality. This flexibility is made possible by the CIShell cyberinfrastructure framework, which is the foundation of our upcoming cyberinfrastructure tools as well. New functionality in Network Workbench includes a collection of algorithms for handling weighted networks, and support for scientometrics analysis and processing. The upcoming EpiC (short for Epidemics Cyberinfrastructure) project aims to create a tool to aid in the modeling, analysis, and visualization of epidemics data. The EpiC project is also developing a community website to facilitate the sharing of datasets in the epidemics community. SciPolicy will expand the scientometrics functionality in Network Workbench into a separate full-fledged tool, making it easy for science policy makers to visualize and understand large sets of scientometrics data. http://www.slis.indiana.edu/media/net_sci_2009/ncs_03_23.mp3 Mon, 20 Apr 2009 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2009/ncs_03_09.mp3 Creative Commons Attribution 3.0 United States - Networks and Complex Systems Spring 2009 (audio): Abstract:With advances in computing techniques, a large amount of high-resolution high-quality multimedia data (video and audio, etc.) has been collected in research laboratories in various scientific disciplines, particularly in cognitive and behavioral studies. How to automatically and effectively discover new knowledge from rich multimedia data poses a compelling challenge since most state-of-the-art data mining techniques can only search and extract pre-defined patterns or knowledge from complex heterogeneous data. In light of this challenge, we propose a hybrid approach that allows scientists to use data mining as a first pass, and then forms a closed loop of visual analysis of current results followed by more data mining work inspired by visualization, the results of which can be in turn visualized and lead to the next round of visual exploration and analysis. In this way, new insights and hypotheses gleaned from the raw data and the current level of analysis can contribute to further analysis. As a first step toward this goal, we implement a visualization system with three critical components: (1) A smooth interface between visualization and data mining; (2) A flexible tool to explore and query temporal data derived from raw multimedia data; and (3) A seamless interface between raw multimedia data and derived data. We have developed various ways to visualize both temporal correlations and statistics of multiple derived variables and as well as conditional and high-order statistics. Our visualization tool allows users to explore, compare, and analyze multi-stream derived variables and simultaneously switch to access raw multimedia data. http://www.slis.indiana.edu/media/net_sci_2009/ncs_03_09.mp3 Wed, 01 Apr 2009 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2009/ncs_03_02.mp3 Creative Commons Attribution 3.0 United States - Networks and Complex Systems Spring 2009 (audio): Understanding ecosystems is one of the most important challenges for theoretical biology and Artificial Life. We offer a bottom-up, fully individual-based model where phenotype-to-phenotype interactions of organisms define ecological networks and we study how simple conditions give rise to complex food webs if we allow for the evolution of phenotypes and hence phenotype interactions. A key element of the model is the notion of "rich phenotype" realized as a set of nonlinear tradeoffs in a multi-trait system. To approach this, we have chosen one of the best understood phenotypes, RNA structures, and assigned ecological functions to their features. In a series of experiments we show the emergence of complex food webs with generic properties, which indicates that minimalist assumptions such as having rich phenotype interactions might be sufficient to generate complex ecosytems and to explain some puzzling ecological features. http://www.slis.indiana.edu/media/net_sci_2009/ncs_03_02.mp3 Wed, 04 Mar 2009 00:00:00 -0500 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2009/ncs_02_23.mp3 Creative Commons Attribution 3.0 United States - Networks and Complex Systems Spring 2009 (audio): The field of mental health services research incorporates researchers and practitioners from the fields such as psychology, psychiatry, social work, health policy, and consumer advocacy. This diverse field saw a marked increase in the publication of recovery-oriented literature and the development of recovery-oriented clinical and organizational practices starting in the mid 1980s and continuing to the present. In services research, the meaning of recovery in severe mental illness (SMI) is contested, but refers broadly to the idea that the long-term prospects of people with SMI need not be dire and illness-defined. Instead, the concept of recovery suggests the care of SMI should be person- and future-oriented and should allow individuals to work toward personally meaningful goals. While this may not seem to outsiders as much of a challenge to service providers, in the 1980s and beyond, recovery became a rallying cry for those who sought to contest overly custodial and pessimistic providers and systems of care. The recovery "movement" in the research literature appears to be what Frickel and Gross termed a scientific/intellectual movement (2005). This study expands the network argument of the SIM framework and examines the evolution of the recovery research network through co-authorship and past and present academic, clinical, disciplinary and other professional affiliations. Multiple types of approaches, including centrality, evolutionary models, and p* models are used to explore this scientific movement. http://www.slis.indiana.edu/media/net_sci_2009/ncs_02_23.mp3 Wed, 04 Mar 2009 00:00:00 -0500 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/rkcsi_2009/rkcsi_2_20.mov - The Rob Kling Center for Social Informatics Speaker Series (video): Digital divide initiatives in developing countries are an important avenue for socio-economic advancement of those countries. Yet, little research has focused on understanding success of such initiatives. The research project, which spans five years with data collected from multiple villages in rural India, seeks to understand the determinants of success of a digital divide initiative. The indicators of success that we examine are economic and health outcomes. Within this broader project, the paper that will be the focus of the presentation and discussion develops and tests a model of technology use and economic outcomes. We use social networks as the guiding theoretical lens as it is well-suited to such a context given the low literacy, high collectivism and an oral tradition of information dissemination in developing countries. We test our model with longitudinal data gathered from 210 families in one village. As theorized, we found that the social network constructs predicted technology use, with the variance explained being 41%. Also, as we predicted, technology use partially mediated the effect of social network constructs on economic outcomes, with the variance explained being 49%. We discuss implications for theory and practice. http://www.slis.indiana.edu/media/rkcsi_2009/rkcsi_2_20.mov Mon, 02 Mar 2009 00:00:00 -0500 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2009/ncs_02_02.mp3 Creative Commons Attribution 3.0 United States - Networks and Complex Systems Spring 2009 (audio): Understanding how organisms control their ionome or mineral nutrient and trace element composition, could have a significant impact on both plant and human health. Furthermore, associating the genetic determinants that underlie natural ionomics variation, with the landscape of the individuals that carry these genotypes, will provide insight into the genetic basis of adaptation and speciation. We have employed high-throughput mineral nutrient and trace element profiling, using inductively coupled plasma – mass spectrometry (ICP-MS), as a tool to determine the biological significance of connections between an organisms genome and its ionome. Our focus is on genes that control uptake and accumulation of mineral elements, including Ca, K, Mg, P (macronutrients in plant fertilizer), Co, Cu, Fe, Li, Mn, Mo, Ni, Se, Zn, (micronutrients of significance to plant and human health) and As, Cd, Na and Pb (elements causing agricultural or environmental problems). To date we have analyzed the ionome of over 100,000 Arabidopsis plants and 20,000 yeast samples. This includes several Arabidopsis forward genetic screens (Lahner et al., 2003 Nat. Biotechnol. 21:1215), a screen of 360 natural Arabidopsis accession, and a complete analysis of all 5153 strains of the yeast deletion collection (Danku et al., 2009 JAAS (in press)). We have successfully used PCR-based positional cloning, DNA microarray based approaches, QTL and association mapping to identify numerous genes that control the ionome (for example Rus et al., 2006 PLoS Genetics 2(12): e210; Baxter et al., 2008 PLoS Genetics 4(2):e1000004). Association of variation in these genes with the landscape in which these plants naturally grow is starting to reveal the genetic architecture underlying specific adaptations to the environment. We are also finding that specific ionomic “fingerprints” are associated with functionally related sets of genes, and also with the physiological status of the organism (Baxter et al., 2008 PNAS 105: 12081-12086). To maximize the value of this ionomics approach, we have developed a publicly searchable online database containing ionomic information on over 1000,000 samples from over 1500 different experiments (www.ionomicshub.org; Baxter et al., 2007 Plant Physiol 143: 600-611), and the database is being updated regularly. http://www.slis.indiana.edu/media/net_sci_2009/ncs_02_02.mp3 Mon, 09 Feb 2009 00:00:00 -0500 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2009/ncs_01_26.mp3 Creative Commons Attribution 3.0 United States - Networks and Complex Systems Spring 2009 (audio): This talk introduces Condor, a tool for dynamic semantic social network analysis, which has been developed for the last six years at the MIT Center for Collective Intelligence in collaboration with University of Cologne, Helsinki University of Technology and others. Condor includes a novel set of social network analysis based algorithms for mining the Web, blogs, and online forums to identify trends and find the people launching these new trends. Algorithms include the temporal computation of network centrality measures, the visualization of social networks as Cybermaps, a semantic process of mining and analyzing large amounts of text based on social network analysis, and sentiment analysis and information filtering methods. The temporal calculation of betweenness of concepts permits to extract and predict long-term trends on the popularity of relevant concepts such as brands, movies, and politicians. Among other examples, our approach will be illustrated by qualitatively comparing Web buzz and Web betweenness for the 2008 US presidential elections, as well as correlating the Web buzz index with share prices.

The advent of social media is disrupting these mechanisms by fostering Web-mediated brokers such as blogs, wikis, folksonomies, and search engines, through which anyone can easily publish and promote content online. This "second age of information'' is driven more than ever before by the economy of attention. Popularity (the accumulation of attention) is its measure of success; popular sources have formidable power to impact opinions, culture, and policy, as well as profit through online advertising. Yet the dynamical processes that drive popularity in our online world are still unclear and largely unexplored. Here we provide for the first time a quantitative, large scale, longitudinal analysis of the dynamics of different popularity measures for online content. We analyze the evolution of two massive model systems, the Wikipedia and an entire country's Web space, finding that the temporal and magnitude behaviors of popularity follow statistical laws typical of critical avalanche processes, such as earthquakes and depinning phenomena. Such statistical features hold across measures, systems, and their histories. To make sense of these empirical results, we offer a model that mimicks with a simple random mechanism the exogenous shift of user attention and the ensuing non-linear perturbations in the popularity ranking of online resources. Remarkably this stylized model recovers the key features observed in the empirical analysis of the two model systems analyzed here.

As these numbers grow, physicians are faced with the increasingly complex task of recognizing and addressing any adverse reactions associated with these treatments. Although information on drug side-effects is readily available, its sheer volume can be daunting: The average drug label contains over 75 potential reactions, and there are many drugs that report well over two-hundred. In this talk, I will discuss the development of an electronic tool which synthesizes adverse reaction data and provides doctors with clinically useful visualizations at the point of care. We will cover many of the challenges in creating such a system, including integration of quantitative and qualitative data, evaluation and iteration of the visualization approach, and actual implementation into physician workflow. http://www.slis.indiana.edu/media/net_sci_2008/ncs_11_03.mp3 Wed, 19 Nov 2008 00:00:00 -0500 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/rkcsi_2008/rkcsi_10_31.mov - The Rob Kling Center for Social Informatics Speaker Series (video): e-Research, which is broadly defined to include distributed and collaborative ICT-enabled research practices across the physical and computational sciences, social sciences, and humanities is an active area of research and funding around the world. However, given the early stages of development of many e-Research projects, we know relatively little about their use and impact on actual research practices and outcomes. Lacking solid evidence, there is a general perception that the social science community in particular lacks a sufficient level of awareness of e-Research, and that this has contributed to a low take-up of advances in ICTs as tools for social research. This talk presents the results of several studies, including surveys and case studies, designed to understand research practices and awareness of e-Research, funding patterns and scholarly publication related to e-Research, and social issues arising from particular e-Research projects. Meyer concludes with a discussion about what social informatics (SI) offers for enhancing our understanding of e-Research. He will argue that employing a balanced view of the relationship between the social and the technical such as that offered by SI can help to understand broader patterns between technological configurations, human actors, resource flows, and the choices that are made about the design and implementation of e-Research technologies. http://www.slis.indiana.edu/media/rkcsi_2008/rkcsi_10_31.mov Thu, 13 Nov 2008 00:00:00 -0500 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2008/ncs_09_29.mp3 Creative Commons Attribution 3.0 United States - Networks and Complex Systems Fall 2008 (audio): The vision of the Semantic Web is to lift current Web into semantic repositories where heterogeneous data can be queried and different services can be mashed up.

The aim of information seeking research should be to ‘bring the information to where the questions are’: axiomatically, the greatest proportion of questions arise when people are mobile and engaged in some activity. If this proposition is true, then information science should be focussed on situational search, as transferring current text retrieval services onto a mobile device does not produce sufficiently compelling results. This lecture will explore situational search and geographic relevance in the light of the continuing revolution in mobile device usage and explore the implications for information seeking with examples from current projects at City University, London and the new Journal of Location Based Services. http://www.slis.indiana.edu/media/rkcsi_2008/rkcsi_04_18.mov Thu, 15 May 2008 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/rkcsi_2008/rkcsi_04_11.mov - The Rob Kling Center for Social Informatics Speaker Series (video): During the 130 years between 1860 and 1990 higher education was transformed, evolving from a limited province of the cultural elite to a great instrument of state material and martial strength.

In this book, he analyzed many different types of charts, network diagrams, and maps, and then developed a systematic description of how information is coded in these visual representations. His goal was to describe pictures in terms of the conventions used to depict the information, not in terms of low-level graphics primitives. In this talk I will review Bertin's ideas, and then describe several recent attempts to formally specify information graphics using computers. The formal approach leads to a language of pictures. We have used visual languages to build two major visualization systems, Polaris and Tableau. Formally describing pictures leads to new capabilities including easy integration with database query languages such as SQL, the ability to describe statistical linear models, and new methods for automatically creating graphical presentations best suited to the data. http://www.slis.indiana.edu/media/net_sci_2008/ncs_04_17.mp3 Tue, 22 Apr 2008 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2008/ncs_04_14.mp3 Creative Commons Attribution 3.0 United States - Networks and Complex Systems Spring 2008 (audio): Cytoscape is an open-source, cross-platform network visualization and analysis application. Cytoscape has it's roots in Systems Biology and is therefore well suited for analyzing data from high-throughput experimentation as well as other molecular state information. The central organizing metaphor of Cytoscape is a network (graph), with genes, proteins, and molecules represented as nodes and interactions represented as edges between nodes. The Cytoscape application acts as an extensible framework by providing core functionality to handle common tasks and software interfaces that allow easy extension to support unique needs. The core functionality includes the visualization, layout, and manipulation of networks in addition to data handling services needed for importing, exporting, and managing network data. Cytoscape's raison d'etre is its ability to integrate data and map it onto visual attributes of the networks. This functionality allows for rich visualizations that can provide insight into otherwise complicated data. In addition to the core functionality we have an ever growing library of plugins that extend and enhance Cytoscape's abilities. Cytoscape is open source (free) and is a collaborative effort of the University of California San Diego, the Institute for Systems Biology, Memorial Sloan-Kettering Cancer Center, Agilent Technologies, Unilever, the Institut Pasteur, University of California San Francisco, and the University of Toronto.

In this work in progress talk, I will argue that many of the more successful multiplayer games, from Parcheesi to Rock Band to Animal Crossing acquire their power by piggybacking on existing social relations, thus acquiring many layers of meaning when played, as well as ambiguously threatening to rewrite these relations. By use of digital and non-digital examples, I will outline a theory of how games acquire meaning from the context in which they are played. http://www.slis.indiana.edu/media/rkcsi_2008/rkcsi_03_28.mov Wed, 09 Apr 2008 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval
