Easy to Visualize

Open Knowledge Viewer reads Excel files, CSV files and RDBMS and can automatically analyze the structure of the data and convert the results into visualizations.

Large Data Sets Acceptable

Open Knowledge Viewer can classify, search and calculate a large data set up to one million rows in local environment. Large Capacity Edition can handle a data set up to two million rows.

Automatic Calculation and Classification of the Data

Open Knowledge Viewer automatically classifies and aggregates items in the data. The data values are calculated by a calculation type and statistical work such as sum / average / standard deviation / variance, etc.

User Friendly Interface

Users can execute operations such as magnification / demagnification, movement, filtering, etc. intuitively just by using the mouse. Also, by configuring icons they can see the movement of the target on the visualization screen.

Visualize

Various Visualization Models

Abundant original visualization models such as Tile, Radar, Network, Flower, and Grape are available together with the basic models.

Screen Segmentation, Full-screen Features

Users can split a visualization screen vertically or horizontally, and see the multiple visualization models in the split areas. Also, users can maximize a single visualization model.

Synchronization among Models

When displaying multiple visualization models, each model synchronizes with one another. This feature enables users to analyze the data from many viewpoints.

Bird's View Point and Detailed View Point

While viewing the entire database on one screen segment, users can focus on specific areas of it on another screen segment.

Analyze

Dynamic Search, Sophisticated Search Engine

Search results will immediately be displayed on the visualization screen. Users can incrementally filter the search results just by one click. Keyword search, relation search, advanced search, etc. are available.

Animation for Dynamic Expressions

By seeing the search result with animation, users can see the data change with time, such as behavioral patterns.

Enhanced Analytical Features

Various types of analyses such as numerical analysis, relation analysis (correlation, directional relation, time relation, hierarchical relation and so on) are available. Advanced statistical features such as regression analysis, correlation analysis, analysis of variance, factor analysis, etc. are loaded, which support users' investigation.

Various Features to Support Analysis

Users can save the search result or the filtering result as a bookmark and restore it later on. They can also take notes on the screen when necessary.

Publish

Saving and Sharing Analysis Results

Visual images can be copied, saved, printed and saved as a PDF file. This enables users to utilize Open Knowledge Viewer for reporting. Users can share the analysis results with other users.
