LINK-GENERATOR(1) General Commands Manual LINK-GENERATOR(1) NAME link-generator - generate natural language sentences using Link Grammar SYNOPSIS link-generator --help link-generator --version DESCRIPTION link-generator is a command-line tool for generating random sentences whose syntax is determined by the specified link-grammar dictionary. EXAMPLE link-generator BACKGROUND The theory of Link Grammar is explained in many academic papers. In the first of these, Daniel Sleator and Davy Temperley, "Parsing English with a Link Grammar" (1991), the authors defined a new formal grammatical system called a "link grammar". A sequence of words is in the language of a link grammar if there is a way to draw "links" between words in such a way that the local requirements of each word are satisfied, the links do not cross, and the words form a consistent connected graph. The authors encoded Eng- lish grammar into such a system, and wrote the link-parser command-line tool to parse English using this grammar. The engine that performs the parsing is separate from the dictionaries de- scribing a language. Currently, the most fully developed, complete dictio- naries are for the English and Russian languages, although experimental, incomplete dictionaries exist for German and eight other languages. OVERVIEW link-generator generates sentences. OPTIONS --help Print usage and exit. --version Print program version and configuration details, and exit. --usage Print a short synopsis of the option flags. -l language|dict_location, --language=language|dict_location Specify the language to use, or the directory file-path to the dic- tionary to use. -s length, --length=length If length is 0, read a sentence template. It may consist of fully spelled-out words as well as wild-cards. The wild-card \* represents any dictionary word. Wild-card specifications like prefix\* and \*.n are also recognized. Otherwise, it specifies the length of the sentences to generate. All generated sentences will have exactly this length. -c count, --count=count Specify the number of sentences to generate. If this number is less than the number of possible linkages, then a random subset of possi- ble linkages will be generated, and one representative sentence for each linkage will be printed. The words in the representative sen- tence are randomly chosen from the set of words associated with each disjunct in that linkage. If the count is greater than the number of possible linkages, then one representative sentence for each linkage will be printed. If the -x option is set, and if the count is greater than the number of possible linkages, then more than one representative sentence will be printed for each linkage. Each sentence will consist of word choices drawn randomly from the set of words associated with each disjunct. An approximately equal number of sentences will be printed for each linkage; if the count is high enough, then all pos- sible word-choices will be printed. Note that this typically results in a combinatorial explosion! -x, --explode If set, and is the count is greater than the number of possible linkages, then more than one sentence will be printed for each link- age. Each sentence will have a distinct random word-choice for that linkage. -d, --disjuncts Display linkage disjuncts. --no-walls Don't attach to walls in wildcard words. -r, --random Use unrepeatable random numbers. -u, --unused Display unused disjuncts. SEE ALSO The link-parser is a command-line tool for parsing sentences. It provides some additional information about the link-grammar implementation. Information on the link-grammar shared-library API and the link types used in the parse is available at the Link Grammar website. Peer-reviewed papers explaining Link Grammar can be found at original CMU site. The source code of link-generator and the link-grammar library is located at GitHub. The mailing list for Link Grammar discussion is at link-grammar Google group.
