It can be used to implement any logic. As of today it is used\nfor [PLN](https://wiki.opencog.org/w/Probabilistic_logic_networks),\nthe [Pattern Miner](https://wiki.opencog.org/w/Pattern_miner) and\n[Relex2Logic](https://wiki.opencog.org/w/Category:RelEx2Logic).\n\nThe strengths of the URE are\n\n* Reads/writes knowledge directly from/to the\n  [AtomSpace](https://wiki.opencog.org/w/AtomSpace).\n* It is generic, can be used to implement any logic, even higher order\n  logics with some limitations.\n* Comes with a powerful control mechanism to speed up reasoning.\n\n# This version of the URE is no longer maintained\n\nEffort has been shifted to [Hyperon Chainer](https://github.com/trueagi-io/chaining).\n\n## Building and Installing\n\n### Prerequisites\n\nTo build the URE you need to first build and install:\n* The [AtomSpace](https://wiki.opencog.org/w/AtomSpace)\n* The [term unifier](https://github.com/opencog/unify)\n\nSee\n[Building-and-installing-the-AtomSpace](https://github.com/opencog/atomspace#building-and-installing)\nfor more information.\n\n### Building URE\n\nBe sure to install the pre-requisites first!\nPerform the following steps at the shell prompt:\n```\n    cd ure\n    mkdir build\n    cd build\n    cmake ..\n    make -j\n```\nLibraries will be built into subdirectories within build, mirroring\nthe structure of the source directory root.\n\n### Unit tests\n\nTo build and run the unit tests, from the `./build` directory enter\n(after building opencog as above):\n```\n    make -j test\n```\nTests can be run in parallel as well:\n```\n    make -j test ARGS=-j4\n```\n\n### Install\n\nAfter building, you must install the URE.\n```\n    sudo make install\n```\n\n## Examples\n\nExamples can be found in this repository under\n\n[URE examples](examples/ure)\n\nAnd\n\n[PLN examples](https://github.com/opencog/opencog/tree/master/examples/pln)\n\nfor PLN in particular.\n\n## More info\n\nThe primary documentation for the URE is here:\n\n* [URE wiki](https://wiki.opencog.org/w/URE)\n* [URE README.md](opencog/ure/README.md)\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fopencog%2Fure","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fopencog%2Fure","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fopencog%2Fure/lists"}
