Eskarn's tutorial for NLP

Adding Words and Sentences to the NLP

Natural Language Processing

PDF VERSIONPDF versions do not get updated as regularly

(anywhere i say npl i mean nlp)


This is an advanced tutorial and probably wont have pictures


How im going to do this tutorial is explain the theory on how the NPL works then cheat after you know how the NLP works you will understand why im gonna cheat


i will be using an unpacked dungeon How to unpack


you will need to have the brain enabled to see the responses and debug mode is always good


settings ini in main folder

runtime
{
  start_mode   = FAST;
 
  debug_sys    = BASIC;
  debug_render = NONE;
  debug_phys   = NONE;
  debug_brain  = ENABLED;
 
  save_key     = "";
}

pack_dungeon\ai\nlp


you will see 59 text files each text file handles different parts of the NLP


lets start with something easy


open up


nlp_actor.txt


lets take the top set

#actor = <you>   : you

#actor is the variable


<you> is the word said by the player


: you is the result


this one is a little bit different

#actor = <#name> : &0


#actor is the variable


<#name> is another variable set below so we are seeing if any of those names have been said


: &0 this is saying the first #variable so #name


if the player said tiffany it would return tiffany

if they said aiko it would return aiko


lets move on to nlp_answer.txt

#answerverb = <#actor can>          : yes,&0,can,present

@answerverb is the variable


<#actor can> remember the #actor from before so if the player says any of the #actor words aswell as can so "you can" "we can" "Samantha can" etc


: yes,&0,can,present this will result as


present.can.#actor.yes with #actor being what was said


well this seems easy

nlp_actor.txt

nlp_answer.txt

nlp_attr.txt

nlp_greet.txt

nlp_object.txt

nlp_question.txt

nlp_verb.txt

are the ones that have mostly single words and then a single responses


lets move on to a harder one


and we will see how this all comes together


open nlp_ac_feel.txt


now you will instantly see it becomes a lot harder


so lets take the first response

#nquestion1 = <how * #qis   * #actor>    : ^qn_how_ac_feel(&1,present)

#nquestion1 is the variable


<how * #qis * #actor> #qis is set in npl_question.txt and #actor we know


so #qis can be "is" "are" "am"

"how is he" "how are you" "how am Samantha"


the * mean anything so the sentence could also be "how is [that] Samantha"

"how [nice] is [this] Samantha" "how [goobly] are [pixydustinface] Samantha"


some of these don't make sense but that's why there is many responses


: ^qn_how_ac_feel(&1,present)


^qn_how_ac_feel the ^ means the variable is not set but do it anyway otherwise there would be an error saying that its not set


the qn_how_ac_feel is used later and it would be


#actor.present


now open

nlp_result.txt


and find


// Actor feel


here is where the qn_how_ac_feel is used

qn_how_ac_feel(*,*)                     : get (form),&0(actor),feel(attr),&1(tense)

qn_how_ac_feel(anything,anything) so basicly #actor.present


: get (form),&0(actor),feel(attr),&1(tense)


e=[get.form,#actor.actor,feel.attr,present.tense])"

#nquestion1 = <how * #qwas  * #actor> : ^qn_how_ac_feel(&1,past)
#question  = <#nquestion1>    : question(&0)
#sentence  = <#question> : &0

then it all comes down to #final in npl_sentence.txt

#final = <#answer #name   * #sentence *>  : &1(&0,&2)


Every result has to start with the actor who the sentence is addressed to.


So #final = <#name #greet *> : &0(&1)


Can parse "Saiko Hello" -> Saiko(Hello)


if it does not have #name it must be "you(&0)"


if you understand all of this and want to try to add words and sentences in go for it otherwise im gonna show you how to cheat


only cheat if you are adding an animation command


copy the nlp_actor.txt and rename it nlp_custom


//////////////////////////////////////////
// Custom
//////////////////////////////////////////
 
 
#custom = <#custom0> : animation(&0)
in_custom(*) : &0(animation),animation(type)
#custom0 = <#customval>           : ^in_custom(&0)
#customval = <* handstand *>     : handstand
#customval = <* bend over bench *>     : benchanal
#customval = <* ride me *>     : rideme
#customval = <* cartwheel *>     : cartwheel


open syntax.txt and add

#include "ai/nlp/nlp_custom.txt"

under #include "ai/nlp/nlp_sentence.txt"


open nlp_sentence.txt

and add

#final = <#custom  *>                       : you(&0)

under nres final 0

this will make our animation response trigger first so don't use already existing words otherwise they will override them


inside the trace.txt after running the dungeon and saying the words

09:39:31 Me: CTALK: "ride me"

09:39:31 BRAIN: "Saiko[TALK]:talk=(closest:2,from:PLAYER,to:you,slen=7,cat=animation,e=[rideme.animation,animation.type])"

09:39:33 BRAIN: "state.code.ref.state.RUN0.animation.rideme"


09:39:31 Me: CTALK: "ride me"// what the player said


to:you// which is the you in #final


slen=7// how many character are in the word "ride me" includes the space


cat=animation// the animation in #custom


I think that's enough on the nlp

If i missed something or something is incorrect then let me know

Good luck
