【问题描述】:
我下载了 tuprolog,但无法获得以下查询的结果,而我在 PROL ide 中得到答案..有人可以帮忙吗?
verb(admit-1).
verb(work-4).
nsubjpass(admit-1, patient-2).
agent(admit-1, doctor-3).
nsubj(work-4, who-5).
aux(work-4, be-6).
rcmod(doctor-3, work-4).
prep_in(work-4, clinic-7).
aggregation('part of').
aggregation('belongs to').
aggregation('subdivision of').
aggregation('have').
aggregation('contain').
aggregation('comprise').
aggregation('include').
aggregation('define').
aggregation('consist of').
aggregation('compose of').
aggregation('denote by').
aggregation('identify by').
aggregation('make up of').
aggregation('record with').
attribute('have').
attribute('contain').
attribute('comprise').
attribute('include').
attribute('define').
attribute('consist of').
attribute('compose of').
attribute('denote by').
attribute('identify by').
attribute('make up of').
attribute('record with').
generalization('be').
generalization('kind of').
generalization('type of').
generalization('classify into').
generalization('consider').
object(X) :- noun(X).
relation(X) :- verb(X).
rel(X,Y) :- nsubjpass(X,Y).
rel(X,Y) :- agent(X,Y).
rel(X,Y) :- nsubj(X,Y).
rel(X,Y) :- aux(X,Y).
rel(X,Y) :- rcmod(X,Y).
rel(X,Y) :- prep_in(X,Y).
associatedWith(X,Y) :- rel(X,Y).
associatedWith(X,Y,Z) :- verb(Y),associatedWith(X,Y), associatedWith(Y,Z).
associatedWith(X,Y,Z) :- verb(X),associatedWith(X,Y), associatedWith(X,Z).
rel_aggregation(X,Y,R):-rel(X,Y).aggregation(R).
?- associatedWith(X,Y,Z).
我需要处理这些关系并让输出再次在 java 中处理
谁能告诉我如何集成prolog和java?
编辑: 我通过实现代码在 tuprolog 中得到了这个错误
此代码适用于 associatedWith(X,Y)。即有 2 个参数,但当我给出 3 个参数时不起作用(X,Y,Z)。怎么办..请帮助我得到这个例外
