nlp - Are there any off-the-shelf solutions for lexical analysis in Haskell that allow for a run-time dynamic lexicon? -

i'm working on little haskell project needs able lex little subset of strictly formed english language in tokens semantic parsing. it's naïve natural language interface scheme many different end effectors can issued commands. i'm using alex this, alex relies on lexicon statically compiled. nature of scheme such number , type of end effectors in world can increment decrease after compilation, , need able add together or remove viable tokens lexicon @ runtime.

i've tried looking around dynamic lexing solutions, , closest this dynamic lexer engine doesn't have been updated since 2000.

i've been considering techniques using less-high level approach (attoparsec, perhaps), or wiring recompilation hook alex , separating lexer rest of application.

are there well-known solutions sort of lexical analysis? intend on working through natural language processing working programmer can take less simplified approach, lexer need.

ctk equivalent of parsec lexing. supports adding new combinators dynamically.

javascript - mongodb won't find my schema method in nested container - i trying access method of schema stored within mixed container. here situation : have cases model can many different things, have schema each of these things stored in "casecontent" mixed property. var caseschema = mongoose.schema({ casecontent : {}, object : {type:string, default : "null"}, collision : {type : boolean, default : false} }); the casecontent property filled model of 1 of schemas, 1 exemple : var treeschema = new mongoose.schema({ applecount : {type : number, default : 3} }); treeschema.methods.dostuff = function (data) { console.log('hey, listen'); homecoming true; }; then, want utilize method of schema original container : caseschema.methods.dostuff = function (data) { if (this.casecontent.dostuff !== undefined) { this.casecontent.dostuff(); console.log('it worked'); } else { ...

Hibernate criteria by a list of natural ids - i trying create hibernate criteria using list of natural ids. saw illustration here http://docs.jboss.org/hibernate/core/3.5/reference/en-us/html/querycriteria.html#query-criteria-naturalid shows illustration querying single record: session.createcriteria(user.class) .add(restrictions.naturalid() .set("name", "gavin") .set("org", "hb")); is there improve way create criteria list of natural ids illustration below? junction junction = restrictions.disjunction() .add(restrictions.naturalid() .set("name", "gavin") .set("org", "hb")) .add(restrictions.naturalid() .set("name", "jdoe") .set("org", "rh")); session.createcriteria(user.class) .add(junction); thanks. in experience, no. reason due limitations of sql in implementations. when seek phrase in sql gets...
