mctext – Using Markov Chains to Generate Text

mctext is a new project of mine, focusing on text generation using Markov Chains. This little utility reads a sample text file, preferably a large one, and generates new text based on the semantics given in the sample text.

How does it work?

mctext reads the given file and treats it as a list of words. Now it randomly chooses two adjacent words and puts in the output string. Now the text generation employs Markov Chains to continue. It takes the last two words in the output string, and searches for all the words that follow them in the sample file. He choose between those words randomly and adds the chosen one to the string. After doing so, it repeats the process until enough new text is generated.

For example, this was an output of the program when given 500 posts from Tech Crunch as sample text:

$ ./mctext -w 100 tc.txt

Compiling and Using mctext

If you want to try it yourself, download the source package from here. Compiling is pretty straight forward (./configure && make). The program depends on the Boost library. Some Linux distributions separate the additional Boost libraries from the core ones, so if it’s your case you will need to install the program-options library.

Invoking the program is simple. Just pass it the sample text file as argument and use -w NUM flag to specify how much words do you want it to generate. mctext can also take the sample text from stdin. See mctext --help for more information.

mctext is a new project, and the current implementation was a proof-of-concept. As such, there is still a lot to improve and look up to.For the next I’m planning to allow changing the number of words considered at each step from the command line, as well as improving the sentence recognition. If you found a bug, or you have any suggestion for new feature I will be glad to hear.

Update: I’ve released a new version of mctext.

    An outgoing Hawking radiated photon, if the mode is extended back into the past region where no observer can go. Tracing the future of this type of wormhole is a white hole is then identified with the cosmological horizon. The problem with white holes emitting matter were one possible solution. A more recently proposed view of the quantum geometry of a black body spectrum predicted to be the result of polar jets formed when matter falls into the past region where no observer can go. Tracing the future of this type of wormhole is a form of leavening agent (such as yeast or baking powder), though many cakes lack these ingredients and cooking techniques. This is necessarily so, since to stay outside a horizon requires acceleration which constantly Doppler shifts the modes.

    Special cake flour tends to result in cakes meant to be soft, light, and upon impact might create MBHs, allowing for observation of their evaporation. Black holes are the same as itself. White holes appear as part of cake decoration. Cakes for special occasions, such as piping bags or syringes, and various techniques, a cake decorator can make many different designs. Basic decorating tips include open star, closed star, basketweave, round, drop flower, leaf, multi, petal, and specialty tips. Royal icing, marzipan (or a less sweet version, known as cosmic rays.

    Recent results from the Hawking radiation has never been observed, nor are there currently viable experimental tests which would allow it to be centered at a finite frequency, if traced back in time. In the late 20th century, new cake decorating products became available to the event horizon, a white hole would absorb far more cosmic microwave background radiation than it emits. A black hole the gravitational effects can be incorporated into quantum mechanics, but nevertheless far from the parent universe. See also Fecund universes. The initial feeding of matter from the black hole has just emitted a particle. In reality, the process is a result of polar jets formed when matter falls into supermassive black holes which lose more matter than they gain through other means are expected to evaporate, shrink, and ultimately vanish.
