Answers

In order to play multimendia documents associated to a concept, is it necessary to have installed some other program in my system?
No. Knowledge Master resolves it on its own, the user does not have to install anything in the system. The question is pertinent only in the case of proprietary formats, that require the presence of the corresponding viewer (Word for '.doc', Excel for '.xls', Acrobat for '.pdf' and so on). Formats like e.g. AVI, WAV, MPEG, MP?, Animated GIF, and so many others, are displayed and managed directly by Knowledge Master.

Assigning an Internet address ("www...") to a concept, causes the loss of other attributes?
No. Concept attributes are maintained as a set, attributes are not exclusive among them.

Which are the minimum necessary computer resources to execute Knowledge Master?
Supported operating systems and hardware requirements for Knowledge Master:

  • Windows XP (Professional, Home or Tablet edition) with 128 MB RAM
  • Windows Server 2003 32 bit with 512 MB RAM
  • Windows Vista (Home/Ultimate/Business) with 512 MB RAM
  • Windows 7, with 1 G RAM
  • Windows 8 / 8.1
  • Windows 10
  • Mac with Virtual PC.

There's no need for third party software.

I'm working on a very complex map: how many levels or strata may I create?
Up until now, a limit to the number of levels has not been found; in our tests, we have not found it, and in theory a practical limit shouldn't be reached. We are aware that one of our users has developed a map with 36 levels. We think it is not very common, though it may evidently happen.

What's the difference between a concept map and a knowledge base?
Scarce and so much. As the concept map concept is frequently associated with that of a mind map or even with a simply drawn schema, the difference depends of what is it that we want to obtain: When relations among concepts in a map are correctly defined, it is possible to ask the map for answer, through semantic searching. This is really the most useful resource for interacting with knowledge.

When e-mailing knowledge bases, how much does it grow the file to be sent, in K?
It does not grow. A map by itself is no bigger than 10-20 K. When it is to be sent it is compressed to about the 20% of its "weight". If the map has external documents associated and the user selects to include them, also these are strongly compressed, except for the files that do not admit any further compression.

I have e-mailed a concept map to a colleague, but he cannot read it with any imaging program.
Knowledge Master normally e-mails the full interactive map, operational by the receiver with the program, it does not send a graphical image. If what you want is to send an image of the map, then you may export it as an image file and send it attached as any other document.

I have downloaded your example maps, but I cannot see them, neither in your sites or in my PC.
The reason is very simple, concept maps are not just images. An image can be created with any graphics software, with results more or less approximated; what defines  a concept mapping software  is not only the resulting image "graphical quality", but the cognitive tools available for map creation and navigation.

To obtain a map "image", it must be exported from the program internal format to a common image format (BMP, PNG, JPEG, etc.), and this is valid not only for Knowledge Master, but for all concept mapping dedicated software products: all concept maps shown by other software producers are also exports to a graphical format. From Knowledge Master it is also possible to export a map image to a graphical format, but we haven't found it useful or technically rigorous to insert these images in our sites as this flattens the map instead of making it fruitful in all aspects.

It is important to bear in mind that a graphical image may be created with any graphics software. The concept map is not an image. That's why we insist that the maps must be seen with the software. The software, besides being the ideal interactive platform for cognitive analysis, for the map author (that may be a student or either the instructor), is a high productivity and precision tool. 

I want to see your maps to evaluate your software through them.
Maps constitute the result of a very personal work: as a matter of fact, everyone constructs the map in a different way, just as he/she "sees", perceives or conceives the subject an object of representation: that's why it is not opportune to evaluate any concept mapping software through other people's maps, it is much better to try to build your own maps, to understand the Knowledge Master's expressive and cognitive power. Else, while it is practically impossible to evaluate maps built by others (because it is like wanting to evaluate art, or an author's opinions), what is possible to evaluate is the knowledge represented in the map.

I'm interested in creating an application with data structures associated to the map for calculations, searching, etc., but I don't know where to start from.

The first step is to start from the menu item "Data management" and create your own data structures, just as specified in the addendum to the main manual, that describes in detail these simple procedures. If you don't have the manual, you can request it from our Support Service. If you have bought the CD after June 2008, you can find it in the \Manuals folder.
