    particular networks NWB will provide advanced visualization tools to interactively explore and understand specific networks as well as their interaction with other types of networks A major computer science challenge is the development of an algorithm integration framework that supports the easy integration and dissemination of existing and new algorithms and can deal with the multitude of network data formats in existence today Another challenge is the design and implementation of an easy to use menu based online portal interface for interactive algorithm selection data manipulation user and session management The NWB will be evaluated in diverse research projects and educational settings in biology social and behavioral science and physics research It will be well documented and available as open source for easy duplication and usage at other sites An annual summer school and a series of workshops and tutorials are planned to introduce the tool to diverse research communities The NWB will provide members of the scientific research community at large biologists physicists computer scientists social and behavioral scientists engineers etc with the means to carry out network analysis modeling and visualization projects in their own fields This will result in a direct transfer of knowledge and results from the fields of specialist network research to a wider scientific community Researchers will have access to validated algorithms that in the past have been obtained through time consuming personal developments of ad hoc computer programs The NWB is expected to enhance and encourage the empirical analysis and model validation of networks generating an eventual acceleration in the development of network science research Online instructional material will support the use of the NWB in educational settings The NWB will provide a unique tool for network science researchers in many disciplines In effect NWB can deploy the knowledge accumulated in network theory

    s New 4 1 Expanded Scientometrics Functionality One of the main focuses of this release is our expanded scientometrics functionality which allows users to process analyze and visualize science publication data from a variety of sources including ISI Scopus Endnote Bibtex and NSF We currently support the extraction of paper citation co author co citation co word and bibliographic coupling networks from scientometrics data sources as well as providing more advanced open ended functionality which is flexible enough to create a wide variety of other networks This release also contains support for basic cleaning and merging of nodes in networks which can be helpful when dealing with less than perfectly clean data Our scientometrics tutorial describing how to use the new functionality is part of the NWB manual 4 2 New Preprocessing Algorithms The NWB 1 0 0 beta release includes a variety of new preprocessing algorithms including various network trimming algorithms the Normalize Text algorithm and the Slice Table by Time algorithm The new network trimming algorithms Extract Top Nodes Extract Top Edges Extract Node Above or Below Value and Extract Edges Above or Below Value allow the removal of nodes and edges based on the values of their attributes making it easy to filter out nodes and edges which are not relevant to your analysis Normalize Text removes stop words and stems remaining words from text table columns making it easier to analyze text with algorithms such as Burst Detection or when extracting co word networks Slice Table by Time allows the user to break a table into one or more tables where each table contains data for a slice of time day year decade etc This makes time series analysis easier and will help support future time series algorithms 4 3 Dynamic Network Analysis Toolkit The Dynamic Network Analysis Toolkit allows users to create and analyze discrete dynamic network models A discrete network model in this context refers to a discrete deterministic model described by a finite number of states along with functions to describe all state transitions These models have been applied successfully to a range of biological systems but can also be used to study the dynamics of non biological systems as well A tutorial for the Dynamic Network Analysis Toolkit can be found at http nwb slis indiana edu Docs NWB DND tutorial pdf 4 4 Export Capability For Various Visualizations Three visualization algorithms Radial Tree Graph with Annotation Force Directed with Annotation and Fruchterman Reingold with Annotation can now export to postscript and Gnuplot is now capable of export data plots for inclusion in PDFs To learn how to utilize these features check the NWB FAQ 4 5 More Comprehensive Documentation The NWB 1 0 0 beta release includes documentation for almost every algorithm in the release available on the NWB Community Wiki as well as documentation for all the data formats supported by NWB We have also created a tutorial for our new scientometrics filling as part of the upcoming NWB manual
