The Department also participated as minor (ad hoc / associate / network) partner in a number of other EU projects, such as TAILOR, MultilingualWeb, PetaMedia, KDubiq, Knowledge Web, OntoWeb, KDnet or MLnet.

Besides the funded projects, there are also long-term informal projects partially aligned with them; they focus on development and maintenance of software tools and other artifacts such as linked datasets, ontologies and standards. The prominent ones are listed in the following table.

Logo	Description	Contact	Group
RDFRules	RDFRules is an analytics engine for rule mining in RDF knowledge graphs. See a live demo and the project repository.	Zeman, Kliegr	DMKD+SWOE
	EasyMiner inductively learns rules using the “web search” paradigm, over an HTML interface. See http://easyminer.eu.	Kliegr	DMKD
	LISp-Miner is a desktop data mining tool for effectively mining richly structured association hypotheses from tabular data; it also features a grid-based mining solution (LM-Grid) and generation of (nugget-containing) artificial datasets suitable for data mining education (ReverseMiner). See http://lispminer.vse.cz.	Rauch	DMKD
GAIN	General Analytics INterceptor tracks and aggregates user interaction with web applications. It powers the http://inbeat.eu platform (placed 2nd out of 17 competitors in the ACM RecSys’13 News Recommender Challenge). Collaboration with the Web Intelligence group at the CTU.	Kliegr	DMKD
EntityClassifier.eu	EntityClassifier (THD tool) identifies entities in text and assigns them DBpedia types. It exploits the Linked Hypernym Dataset containing millions of entity-type assignments, of which most are novel w.r.t. both DBpedia and Yago 2s. See http://entityclassifier.eu/ and http://ner.vse.cz/datasets/linkedhypernyms/. Collaboration with the Web Intelligence group at the CTU.	Kliegr	DMKD+SWOE
	PatOMat is a suite of tools for pattern-based transformation of ontologies and vocabularies. It among other includes a graphical plugin for Protégé, called GUIPOT. Best demo award at EKAW’12. See http://patomat.vse.cz/.	Zamazal Dudáš	SWOE
	OpenData.CZ is a joint initiative with Charles University, Prague, towards linked open government data publication (in Czech Republic and EU in general). In this context the Public Contracts Ontology has been developed, and a number of open datasets have been RDFized. See http://opendata.cz/en.	Svátek	SWOE
	Within the OpenBudgets.eu project, an RDF data model for fiscal data based on the Data Cube Vocabulary has been developed, and is used by the project partners as well as several other parties.	Svátek	SWOE
CZ	Czech DBpedia is a national branch of DBpedia. It contains structured information in RDF, automatically extracted from Czech Wikipedia using mapping rules and other inventory.	Zeman Svátek Kliegr	SWOE
	DB-quiz is a game in which two players strive to connect the three sides of the triangular board by occupying hexagonal fields. A field is occupied through correctly answering a question generated from a fact base: Czech or English DBpedia, or a custom one. The challenging aspects of the game design are question despoilerification and difficulty rating.	Zeman	SWOE
	SPARQLab is an online exercise book for learning the SPARQL query language. The current version uses the linked dataset of the Czech Social Security Administration. (Both the application and the dataset documentation is currently in Czech only.)	Svátek	SWOE
LODSight	LODSight is a linked dataset summarization tool with special focus on employed vocabularies. It aims to give insights into a dataset and vocabularies at the same time, by distinguishing between different vocabularies and providing examples of concrete values from the dataset as annotations to the summary graph.	Dudáš Svátek	SWOE
PURO	PURO is a formalism designed for “style-neutral” ontological background models from which OWL models in different modeling styles can be generated. Two interconnected tools have been developed for authoring PURO models and generation of OWL models from them: PURO Modeler and OBOWLMorph.	Dudáš Svátek	SWOE
OOSP	OOSP, Online Ontology Set Picker, is a tool for rapidly building tailored collections of ontologies based on their various metrics. Such collections can then be used as benchmarks for testing ontology management tools. The source collections used are LOV and Bioportal.	Zamazal	SWOE
NEST	NEST is an expert system shell with multiple methods of uncertainty processing and reasoning algorithms. Desktop version at http://sorry.vse.cz/~berka/NEST; web-based version at http://nest.vladalas.info/; newest domain-specific application (ontology visualization tool recommender) at http://owl.vse.cz:8080/OVTR/.	Berka	IIS
AIQ	Extended AIQ test: Algorithmic Intelligence Quotient test (Legg and Veness, 2013) is a test of machine intelligence that approximates the Universal Intelligence of an agent (Legg and Hutter, 2007). The extended version available at https://github.com/xvado00/AIQ/releases addresses several issues of the original test. Also available at https://github.com/xvado00/SemAnEP-tool/releases is a tool to conduct semantic analysis of environment programs used by the test.	Vadinský	IIS
	JNVDL is a Java-based tool for controlling the processing and validation of compound XML documents. See http://jnvdl.sourceforge.net.	Kosek	WELT
	Support of the Internationalization Tag Set Version 2.0 in the W3C Markup Validator. See http://www.w3.org/TR/its20 and http://validator.w3.org.	Kosek	WELT
