        "description": "What is Bridge?\n===============\n\nBridge is a light-weight portable library for natural language processing and because of its tiny size it can be easily ported to any programming languages. As of now Bridge provides a Python Library in 50 SLOC and a JavaScript one in 78 SLOC.\n\nHow Bridge Works?\n=================\n\nUnlike other natural language processing approaches that investigate grammatical features of a language, Bridge aims the structred meaning. Bridge knows the meaningful parts of a text and instead of grammatically examining it to extract meaning, it literally understands the sentence.\n\nA Sample Program with Bridge\n============================\n\nIt's better to show the power of Bridge with an example, thus let's build a simple calculator with Bridge!\n\nFirst we should construct a Bridge Object:\n\n  Bridge = bridge();\n\nNow, Let us add our Meaning Models to Bridge. First of all, we'll teach it what is a number. We'll use a grammar object to teach Bridge a new concept. Each grammar has one or more \"type\" or \"role\", for example our number have role \"number\". Also, we need some definitions to create a grammar. Each definition or model, should have a single \"type\" and a regex pattern to test atoms passed to it. Each grammar has a \"value\" that Bridge uses to create the resulting atom. Finally each grammar has a \"weight\" that shows the importance of the grammar.\n\nWhen first Bridge examines a sentence, it breaks the sentence to atoms. Each atom shows a meaningful part of speech in Bridge, At the first examination Bridge gives all of the atoms a \"word\" type.\n\nWe'll teach the number model as follows::\n\n    Bridge.add_grammar(\n      grammar(\n        ['number'],          # grammar type\n        [definition(         # definitions\n          'word',            # type of atom to accept\n          r'^\\d+$')],        # regex to match atoms against\n        '{0}',               # grammar value\n        0));                 # weight\n\nNow let's teach it the basic mathematical operators::\n\n    Bridge.add_grammar(grammar(['plus'], [definition('word', r'^\\+$')], '{0}', 0)) # plus\n    Bridge.add_grammar(grammar(['minus'], [definition('word', r'^-$')], '{0}', 0)) # minus\n\nNow we'll teach mathematical operations and use the models we've already defined::\n\n    Bridge.add_grammar(\n      grammar(['plus-command', 'number'],\n                  [definition('number', r'.*'),\n                   definition('plus', r'.*'),\n                   definition('number', r'.*')],\n                  '(+ {0} {2})', 1));\n\n    Bridge.add_grammar(\n      grammar(['minus-command', 'number'],\n                  [definition('number', r'.*'),\n                   definition('minus', r'.*'),\n                   definition('number', r'.*')],\n                  '(- {2} {0})', 1));\n\nNow Bridge can do simple mathematical operations, for now it can take this::\n\n    1 - 2 + 3 - 4 + 5\n\nAnd convert it to the following lisp code::\n\n    (+ (- 4 (+ (- 2 1) 3)) 5)\n\n(you may run this lisp using hy) It's time to teach Bridge some natural language::\n\n    Bridge.add_grammar(\n      grammar\n        (['and'],\n         [definition('word', r'^and$')],\n        '{0}', 0));\n\n    Bridge.add_grammar(\n      grammar(\n        ['numeral-and', 'number'],\n        [definition('number', r'.*'),\n         definition('and', r'.*'),\n         definition('number', r'.*')],\n        '{0} {2}', 2));\n\n    Bridge.add_grammar(\n      grammar\n        (['sum-command'],\n         [definition('word', r'^sum$')],\n        '{0}', 0));\n\n    Bridge.add_grammar(\n      grammar(\n        ['complete-function'],\n        [definition('sum-command', r'.*'),\n         definition('numeral-and', r'.*')],\n        '(+ {1})', 3))\n\nUsing the following code::\n\n    sentence = \"sum 3 + 4 and 5 and 6 - 7 and 4\"\n    print(Bridge.process(sentence)[0].value))\n\nWe'll get::\n\n    (+ (+ 3 4) 5 (- 7 6) 4)",
