Algernon.jpg
Algernon
Algernon performs forward and backward rule-based processing of frame-based knowledge bases, and efficiently stores and retrieves information in ontologies and knowledge bases.

ClojureTab
USEFUL TOOL FOR KNOWLEDGE PROCESSING IN PROTEGE.

The ClojureTab uses the Clojure programming language for simple programming in the Protege environment, on-the-fly debugging, and storing programs in Protege projects. Contains: 1. Integrated development environment for Clojure language (https://clojure.org/) 2. Protege API for Clojure language 3. Rule engine and Expert system shell rete4frames (https://github.com/rururu/rete4frames) 4. Algorithms visual development environment

Dllearner protege plugin.png
DL-Learner
The DL-Learner plugin allows learning equivalence and super class axioms based on the instance data in the ontologies loaded in Protégé.
DroolsTabScene-5.0.png
DroolsTab
DROOLS BASED SPATIAL SCENARIO SIMULATION PLUG-IN

The DroolsTab uses the open source geo-information system Java library OpenMap and the open source Java RETE rule engine Drools to facilitate visual authoring of complex spatial process simulation scenarios and general rule-based authoring. The Groovy and Clojure languages can be used for authoring auxiliary pieces of code and scripts. The distribution includes several demos of spatial simulation in the sea, air, and ground environments, including one example using Edvin Boehn's KML Framework.

[[Image:|thumb|170px|center]] ELK
ELK is a free and open source reasoner for the lightweight ontology language OWL 2 EL.
EZPal.jpg
EZPal
Facilitate acquisition of Protege Axiom Language (PAL) based constraints without having to understand the language itself.
R4f.jpg
Expert System Shell r4f-pro
Integrated Development Environment for rete4frames rule engine and expert system shell based on Protege-3.5 ontology editor supplemented with visual creation of algorithms. It combines two well-known paradigms of software development: algorithms for strictly defined processes and rules for fuzzy, fragmentarily defined processes and phenomenons.
FuzzyOWL2.gif
FuzzyOWL2
FuzzyOWL2 (Fuzzy OWL 2) is a plugin for Protege 4.1 that allows users to edit, save Fuzzy OWL 2 ontologies, and submit queries to the underlying inference engine FuzzyDL.
HERAKLES Screenshot.jpg
HERAKLES
The HERAKLES plug-in provides an extension to Protégé 4 to use the HERAKLES reasoning broker framework.
[[Image:|thumb|170px|center]] HermiT
HermiT is a reasoner for ontologies written using the Web Ontology Language (OWL). Given an OWL file, HermiT can determine whether or not the ontology is consistent, identify subsumption relationships between classes, and much more.
[[Image:|thumb|170px|center]] HyperMod
HyperMod is a module extraction tool based on reachability in hypergraphs. These modules are similar to syntactic locality based modules but has the potential of being substantially smaller.
IndividualPropertiesContextualAssertionsPlugin.jpg
Individual properties contextual assertion
The view offers a more comfortable and advanced way to make individual properties assertions compared to the default Protégé "Property Assertions" view.

The view is available from: Window -> Views -> Individual Views -> Properties contextual assertions.

Jess.gif
JessTab
JessTab provides a Jess console window where you can interact with Jess while running Protégé.
MESAMTab.png
MESAM
The protégé MESAM plugin is a semi-automatic tool for defining a consistant OWL merged model composed of a generic model, a specific model and mapping between them.
NoHRv2.png
NoHR
NoHR (Nova Hybrid Reasoner) is a plug-in for Protégé that allows its users to query knowledge bases composed of an ontology in OWL 2 EL or OWL 2 QL (from version 2.0.0 on) and a set of Reasoning Rules.

Using a top-down reasoning approach, which means that only the part of the ontology and rules that is relevant for the query is actually evaluated, NoHR combines the capabilities of ELK and a dedicated direct translation for OWL 2 EL and OWL 2 QL respectively with the rule engine XSB Prolog to deliver very fast interactive response times.

[[Image:|thumb|170px|center]] Ontop
Ontop is a platform to query databases as Virtual RDF Graphs using SPARQL. It's extremely fast and is packed with features. Ontop is an open-source Ontology Based Data Access (OBDA) system that allows for querying relational data sources through a conceptual representation of the domain of interest, provided in terms of an ontology, to which the data sources are mapped. Key features of Ontop are its solid theoretical foundations, a virtual approach to OBDA that avoids materializing triples and that is implemented through query rewriting techniques, extensive optimizations exploiting all elements of the OBDA architecture, its compliance to all relevant W3C recommendations (including SPARQL queries, R2RML mappings, and OWL 2 QL and RDFS ontologies), and its support for all major relational databases.
[[Image:|thumb|170px|center]] Owl2Cool
Owl2Cool is a tab-widget which provides an interface to Protege users for transorming a given OWL ontology to the object-oriented language COOL. After the transformation it produces in the given path a .clp file which can then be loaded to CLIPS for programming with production rules.
PSMTab-selection.jpg
PSM Librarian
Supports users in building knowledge-based applications out of reusable knowledge components known as Problem-Solving Methods (PSMs).
Pal-constraints-tab.gif
Protege Axiom Language (PAL) Tabs
Express constraints about a knowledge base and make logical queries about the contents of a knowledge base
RacerProTG-Screenshot.JPG
RacerProTG
The RacerPro Plugin for Protégé offers reasoning functionality to Protégé 4.x. Once installed the plugin downloads a special but free version of the RacerPro inference server (aka "RacerProTG") and adds RacerPro to the "Reasoner" menu.
SWRL-IQ wine-properties.png
SWRL-IQ
SWRL-IQ (Semantic Web Rule Language Inference and Query tool) is a plugin for Protege 3.4.x that allows users to edit, save, and submit queries to an underlying inference engine based on XSB Prolog.
SWRLTab.png
SWRLTab
The SWRLTab is a Protégé plugin that provides a development environment for working with SWRL rules and SQWRL queries.

Documentation for the Protégé 5-based version can be found (here)[1].

Documentation for the Protégé 3-based version of the SWRLTab can be found (here)[2].

[[Image:|thumb|170px|center]] Snorocket
Snorocket for Protege is a Java implementation of the polynomial classification algorithm described by Baader et al in Pushing the EL Envelope and packaged for use as a reasoner in Protege.

Snorocket is capable of classifying SNOMED CT in under 1 minute.

SnowOwl.png
Snow Owl
Snow Owl is a free SNOMED CT browser and authoring tool integrating Protégé.
