Fixed a bug in Compiler that was causing it not to appropriately reference the aliases of nodes (w.r.t. MEBN polymorphism) in the LPD script. For instance, a condition like "parent = true" may not pass if parent has aliases and only the aliases have value = true. Also developed a regression test to test this bugfix.

Created a method in JunctionTreeAlgorithm that will print to unbbayes.util.Debug some complexity metrics (e.g., parents per node, clique size, etc.) before actually instantiating the Junction Tree itself. A boolean flag can be used to enable/disable this feature (while Debug.setDebug(false) can also be used disable the Debug console itself).
-
Fixed a similar bug in PowerLoomKB and OWLAPICompatiblePROWL2IO that was not releasing/closing the input file after it's loaded (so we were unable to delete the files without closing the Java application). Now the input files are released so we can delete the files without quitting the application.

Commit r4697 addresses this issue for the boolean absurd state (although it does not address the issue of mixture of categoricals and object entity caused by OWL2 punning).
-
Addressed bug #198 for boolean "absurd" only.

UnBBayes-PR-OWL2 plugin requires direct import of PR-OWL2 schema
-
UnBBayes-MEBN does not support possible values of multiple types (e.g., hierarchy of types).

Completed major bugfixes on NaiveBayesHypothesisManagement (and included regression tests).
-
Added new sample SSBN to VehicleIdentification resources.
-
Modified the IdAwareCSVMultiEvidenceIO to also consider class names. Made respective bugfixes and changes to test units.

Bugfixes to IdAwareCSVMultiEvidenceIO. Also made minor refactoring: moved some classes to appropriate packages.

I cannot find any major issues in the sample code you have shown in your last post, except 4 minor/potential issues: net.updateEvidences() is marked for deprecation. It's there only for backward compatibility and should be avoided. It does not work well with virtual (likelihood or soft) evidence and will mess up your likelihood evidence. It is superseded by algo.propagate() (so just invoke 'algo.propagate' only). I'm not sure what posterior probability you are expecting, but adding a likelihood evidence...
-
Added a test method to contrast ProbabilisticNetwork#updateEvidences() and JunctionTreeAlgorithm#propagate().
-
Created a JUnit test specifically for SimpleTurtleIndividualGenerator.
-
Added comments/instrumentation to SimpleTurtleIndividualGenerator.java
-
Initial implementation of a class to generate sample instances and another to filter out instances from an ontology given some naive bayes reasoning to rank the N most probable instances (and filter out the rest).

Hello, I just found examples from the website to perform propagation using the JunctionTreeAlgorithm. Here's the propagation section of my code: JunctionTreeAlgorithm algo = new JunctionTreeAlgorithm(); algo.setNetwork(net); algo.run(); // Step 3: Add HARD evidence ProbabilisticNode opNode = (ProbabilisticNode) net.getNode("TerrainType__Rgn1"); opNode.addFinding(1); // e.g., TerrainType = Road System.out.println("[HARD] TerrainType__Rgn1 = Road"); // Step 4: Add SOFT evidence ProbabilisticNode matNode...

Hello, I am working with PR-OWL2 in UnBBayes and implementing probabilistic reasoning for the vehicle example in Java. I successfully executed a query on the vehicle model, but I am encountering issues when trying to run propagation using the Junction Tree Algorithm. Problem Description 1. Findings Do Not Affect Propagation – When I add findings or change finding on owl files(hard evidence or likelihood) to a node, the probabilities update after query and before inference, but after running propagation,...

Hi, I am trying to use PR OWL 2.0 for my project. I have been doing tutorial on PR-OWL 2 on Patient diagnosis. However, I am having trouble importing an OWL file in UnBBayes. It says Error to load a net file. My system is Macbook air M1 and I am using protege 5.6.4 to create an owl file. Can someone help me with this?

Both Jena and UBF do not seem to allow values/instances with names starting with numbers. Modified PossibleValuesEditionPane to block such naming patterns.

Added JUnit test that verifies that a manually-created Turtle file can be used to read findings.
-
Ensure temporary finding files are deleted at the end of the tests (to ensure the write locks are released appropriately).
-
Added a JUnit test to verify that manually-edited findings in KIF text can be loaded in UnBBayes-MEBN too. This shows how to programmatically batch-insert findings (just by adding new KIF lines to PLM files).

Fixed a bug (and created a regression test) that happened when loading a PR-OWL1 file edited by external tools. If the external tool saves the PR-OWL1 file as RDF or OWL2, then Jena will start interpreting the individuals as RDFIndividuals instead of the OWLIndividuals (which is expected by PR-OWL 1 code).

Hello, may I ask what method to use to import evidence in bulk into MEBN? I don't want to manually add evidence through the show findings editing pane in Unbbayes!!!

Thank you so much, I am embarrassed at my mistake, but with your response, it makes perfect sense.

Just an additional comment about the spreadsheet: What I did in the spreadsheet is not a replica of what the UnBBayes software does.. UnBBayes uses a factored/efficient algorithm, while the spreadsheet is a pure brute-force calculation (because I created a big table containing all states of all nodes and multiplied all CPTs together). Therefore, the spreadsheet won't be replicating the same bugs in UnBBayes (I'm not talking about presence/absence of bugs -- just saying that it's unlikely that these...

A quick'n'dirty explanation is that your network at the right have A, B, and C independent each other, while in the network at the left (when you insert evidence to the Child), the nodes A, B, and C are NOT independent anymore (they became conditionally dependent given the Child -- it's the so called "explain-out" relationship). Virtually speaking, it's like the network at the left had A, B, and C connected with "invisible" arcs, so you were virtually comparing two networks with "different" structures....

When I propagate evidence after updating a child node The parents of the children calculate as expected but the other children of those parents give unexpected values. I have included an example where if you set the child to a status of "failed" you get a different result than you would get if you simply set the values of the parents. Wondering if my understanding of how evidence propagation works is incomplete or if I have discovered a bug?
