NetMiner Upgrade to ver.3.4.0 (07-07-09) |
|
| |
Dear NetMiner Members,
Today, we are pleased to announce that NetMiner is updated to version 3.4.0.
This is the 8th upgrade following the official release of NetMiner 3 on May 15th, 2007.
I. New Modules
1. Transform >> Linkset >> Link Reduction
Link Reduction is a data transformation module for extracting links according to the weight of links with some options. Supported options are extracting method and handling tie value option.
2. Transform >> Matrix >> Vectorize
Vectorize (1-mode or 2-mode) module transforms a matrix into a vector. The node pairs or links in the input matrix become a nodeset in the transformed data. And the link weight will be transformed as an attribute of each nodeset.
3. Transform >> Mode >> Tree Construction
Tree Contruction is a data transform module for constructing tree type data from node attributes including multi-level hierarchical information. The constructed data can be added as a new 2-mode network data for related analysis modules (Analyze >> Position >> Expand / Collapse)
4. Analyze >> Neighbor >> Equicentrality
EquiCentrality is an analysis module that calculates the degree of similarity between the connected nodesˇ? centralities. Although it is similar to ˇ®Assortativityˇ? (Newman 2002), Equicentrality is based on the Euclidean distance. For users focusing on the distance of the nodeˇ?s centralities, Equicentrality would be a good choice, other than ˇ®Assortativityˇ? which is based on correlation. (SoongMoon Kang, 2007)
5. Analyze >> Cohesion >> Community >> Label Propagation
Label Propagation for detecting the community structure of the network with a low complexity of O(m) is added as a new Community Detection Module. This is implemented simply by labeling all nodes, and then letting each node take the most frequent label observed from its neighbors, through iteration steps (U. N. Raghavan, R. Albert, and S. Kumara ,2007).
6. Analyze >> Position >> Expand / Collapse
Expand / Collapse is an analysis module for exploring hierarchical structure with flexible options. Blockmodeling results and related network map can be generated easily using flexible options for expanding and collapsing the level of hierarchical structure.
7. Analyze >> Property >> Modularity
Modularity is a measure to indicate how well the network is divided by the given partition. The NetMiner Modularity module simply provides an interface allowing the users to compute the modularity value for the network partitioned by specified vectors ( M. E. J. Newman, 2006).
II. Enhanced Features
1. Map Control Improvement
Some useful user activities on the network map are supported as new features: deselecting pendant nodes, drawing network map with some selected nodes fixed, using mouse wheel in Visualize Neighbor sub window etc.
2. SVG Image Quality Improvement
The quality of arrow color and node shape in SVG (Scalable Vector Graphic) image file is improved.
3. Link Threshold Control Item Improvement
Now users can select links on the network map more conveniently just by dragging slide bar according to the weight of links.
4. DB Connection Module Improvement
Now MS Access can be selected as DBMS type for importing DB Tables into NetMiner (available on DB Connection Package).
5. Styling Option Improvement
Users can select links on the network map by giving the minimum value and the maximum value. Since the function can be operated with a slide bar, it is more convenient for users.
6. Data Handling Option Improvement
Output Tables can be opened in MS Excel more conveniently without taking trouble to copy and paste.
7. Decimal Point (Number Precision) Control Improvement
Decimal place of the figures in the Output Results can be raised without limit.
Decimal place can be set globally through more comprehensive Preference menu feature.
8. Automatic Update Support
Now users can be alarmed about new updates on starting NetMiner.
III. System Enhancement and Bug-fix
1. Performance of P* (ERGM) model is enhanced. Now the algorithm runs faster and handles larger data than former versions.
2. The registration dialog is enhanced regarding off-line registration function. In fact, the function was added last year, but now the function can be accessed more easily.
3. Some of 'Out of Memory' errors are fixed.
For your information:
