What's New#
The release includes the following notable features:
d3web#
- New problem-solving engines can be added using the new plug-in architecture.
- Offers problem-solving methods for heuristic scoring rules, extensible covering models, abstraction rules, and indication rules.
- Loading and storing performed problem-solving sessions.
- Empirical testing testing feature that runs test cases to evaluate a knowledge base.
- (Experimental) version of a temporal database storing and reasoning with sequential system inputs.
- (Experimental) DiaFlux engine for representing and running guideline knowledge
KnowWE#
- Extensions for defining knowledge bases using rule-based and set-covering knowledge.
- Plugin for running test cases within the wiki.
- (Experimental) version of markups to define time-values events and abstractions.
- denkbares Dialog for running test cases interactively (as preview).
Known Issues#
- BugZilla #36: [KnowWE] "Vorschau"+"Speichern" (Preview) removes content
If you use the "Vorschau" Button after entering a text, no content is shown.
Assuming that the preview has problems in showing dynamic content I pressed save-button to view the text. After that the article was completely empty, all content was deleted. - BugZilla #38 - [TimeDB] Gradient calculation shows strong deviation for outlier values.
TimeDB does not store constant values (i.e., values that remain the same over a time duration), but only the first occurrence of the value. If the value changes dramatically, then the gradient function computes a stronger deviation as expected. - BugZilla #39 - [DenkbaresDialog] Creating a new Case doesn't work
When clicking the "New" button, the dialog scrolls down and all answers remain set. Instead of this behaviour a new case should be created and the dialog should start with the first question. - TRAC #192: [QuickInterview] Questionnaires are unintentionally collapsed after answering a question:
- TRAC #193: [QuickInterview] QuickI does not show the "unit" information for numerical question, when available. Should be shown in the dialog directly after the input field.
- TRAC #194: [QuickInterview] Missing value range handling for num questions. For num questions, the "value range" information is not taken into account, e.g. for a value range (1 10) it is possible to enter a value = 11.
- TRAC #195: [QuickInterview] No keyboard handler for num input fields. For num questions, hitting "Return" in the numerical input field does not send the entered value.
- TRAC #196: [QuickInterview] Input field for num questions expect "." als float separator. In an input field of a numerical question, you need to separate a float number by "." - the character "," is not accepted.
- KnowWE - Documentation, as contained in the core pages of the wiki, is slightly deprecated, since it introduces the old markup syntax (however, it is still working and compatible)
- KnowWE - [QuickInterview] The entry of multiple-choice values do not work properly under all circumstances.
System Requirements#
Installation of d3web/KnowWE requires the Java Platform, Standard Edition JDK 6 Update 21 or better. For operating systems, the distribution runs with MS-Windows XP, Windows 7 and Mac OS 10.6. Linux is not officially supported. We officially support Firefox 3.6 or better but most parts are also working with the latest versions of the Internet Explorer and Google Chrome.
