我需要在斜杠上分开然后报告标记。这是hunspell词典格式。我试图在github上找到一个可以做到这一点的类,但找不到一个。
# vi test.txt
test/S
boy
girl/SE
home/
house/SE123
man/E
country
wind/ES
代码:
from collections import defaultdict
myl=defaultdict(list)
with open('test.txt') as f :
for l in f:
l = l.rstrip()
try:
tags = l.split('/')[1]
myl[tags].append(l.split('/')[0])
for t in tags:
myl[t].append( l.split('/')[0])
except:
pass
输出:
defaultdict(list,
{'S': ['test', 'test', 'girl', 'house', 'wind'],
'SE': ['girl'],
'E': ['girl', 'house', 'man', 'man', 'wind'],
'': ['home'],
'SE123': ['house'],
'1': ['house'],
'2': ['house'],
'3': ['house'],
'ES': ['wind']})
SE小组应使用3个单词“ girl”,“ wind”和“ house”。应该没有ES组,因为包含了ES组,并且与“ SE”相同,并且SE123应该保持不变。我该如何实现?
更新:
我已经设法添加了二糖,但是我如何添加3、4、5克呢?
from collections import defaultdict
import nltk
myl=defaultdict(list)
with open('hi_IN.dic') as f :
for l in f:
l = l.rstrip()
try:
tags = l.split('/')[1]
ntags=''.join(sorted(tags))
myl[ntags].append(l.split('/')[0])
for t in tags:
myl[t].append( l.split('/')[0])
bigrm = list(nltk.bigrams([i for i in tags]))
nlist=[x+y for x, y in bigrm]
for t1 in nlist:
t1a=''.join(sorted(t1))
myl[t1a].append(l.split('/')[0])
except:
pass
我想如果在源代码中对标签进行排序会有所帮助:
with open('test1.txt', 'w') as nf:
with open('test.txt') as f :
for l in f:
l = l.rstrip()
try:
tags = l.split('/')[1]
except IndexError:
nline= l
else:
ntags=''.join(sorted(tags))
nline= l.split('/')[0] + '/' + ntags
nf.write(nline+'\n')
这将创建一个带有分类标签的新文件test1.txt。但是trigrams +的问题仍然没有解决。
我下载了一个示例文件:
!wget https://raw.githubusercontent.com/wooorm/dictionaries/master/dictionaries/en-US/index.dic
使用“ grep”命令的报告是正确的。
!grep 'P.*U' index1.dic

在分类标签文件上使用bigrams的python报告并不包含上述所有单词。
myl['PU']
['aware',
'aware',
'conscious',
'faithful',
'grateful',
'lawful',
'natural',
'obtrusive',

'wholesome',

鉴于我正确理解,这更多的是构建一个数据结构,对于给定的标签,该数据结构构造正确的列表。我们可以通过构造仅考虑单数标记的字典来做到这一点。稍后,当一个人查询多个标签时,我们将计算交集。因此,这使得它的表示形式紧凑,并且易于提取所有带有标签AC
的元素,这将列出带有标签ABCD
,ACD
,ZABC
的元素等
因此,我们可以构造一个解析器:
from collections import defaultdict
class Hunspell(object):
def __init__(self, data):
self.data = data
def __getitem__(self, tags):
if not tags:
return self.data.get(None, [])
elements = [self.data.get(tag ,()) for tag in tags]
data = set.intersection(*map(set, elements))
return [e for e in self.data.get(tags[0], ()) if e in data]
@staticmethod
def load(f):
data = defaultdict(list)
for line in f:
try:
element, tags = line.rstrip().split('/', 1)
for tag in tags:
data[tag].append(element)
data[None].append(element)
except ValueError:
pass # element with no tags
return Hunspell(dict(data))
完成__getitem__
末尾的列表处理以按正确的顺序检索元素。
然后我们可以通过以下方式将文件加载到内存中:
>>> with open('test.txt') as f:
... h = Hunspell.load(f)
并查询任意键:
>>> h['SE']
['girl', 'house', 'wind']
>>> h['ES']
['girl', 'house', 'wind']
>>> h['1']
['house']
>>> h['']
['test', 'girl', 'home', 'house', 'man', 'wind']
>>> h['S3']
['house']
>>> h['S2']
['house']
>>> h['SE2']
['house']
>>> h[None]
['test', 'girl', 'home', 'house', 'man', 'wind']
>>> h['4']
[]
查询不存在的标签将导致一个空列表。因此,这里我们在调用时推迟了“交叉点”过程。实际上,我们已经可以生成所有可能的交集,但这将导致庞大的数据结构,甚至可能需要大量工作
答案 1 :(得分:2)
尝试一下:
myl=dict()
with open('test.txt') as f :
for l in f:
l = l.rstrip()
try:
tags = l.split('/')[1]
myl.setdefault(tags,[])
myl[tags].append(l.split('/')[0])
for t in tags:
myl.setdefault(t,[])
myl[t].append( l.split('/')[0])
except:
pass
keys=myl.keys()
for k1 in keys:
for k2 in keys:
if len(set(k1).intersection(k2))==len(set(k1)) and k1!=k2:
myl[k1].extend([myk2v for myk2v in myl[k2] if myk2v not in myl[k1]])
print(myl)
输出
{'S': ['test', 'test', 'girl', 'house', 'wind'], 'SE': ['girl', 'house', 'wind'], 'E': ['girl', 'house', 'man', 'man', 'wind'], '': ['home', 'test', 'test', 'girl', 'house', 'wind', 'man', 'man'], 'SE123': ['house'], '1': ['house'], '2': ['house'], '3': ['house'], 'ES': ['wind', 'girl', 'house']}
在程序的最后两个for循环中,首先获取k1
和k2
的集合,然后比较这两个集合的交集。如果相交的长度等于集合k1
的长度,则键{{1}}的值应在键k2
中,因此键{{1}的值}添加到键k1
中。

willem van onsem已经回答的简单得多的版本
data = defaultdict(list)
with open('text.txt') as f:
for line in f.readlines():
try:
element,tags = line.rstrip().split('/', 1)
print(element)
for tag in tags:
data[tag].append(element)
data[None].append(element)
except ValueError:
pass
def parse(data,tag):
if(tag==None or tag==''):
return set(data[None])
elements = [set(data[tag_i]) for tag_i in tag]
return set.intersection(*map(set, elements))
>>> parse(data,'ES')
>>> {'girl', 'house', 'wind'}
>>> parse(data,None)
>>> {'girl', 'house', 'man', 'wind'}
>>> parse(data,'')
>>> {'girl', 'house', 'man', 'wind'}
