汉字转拼音
HanLP中的汉字转拼音功能也十分的强大。
说明:
- HanLP不仅支持基础的汉字转拼音,还支持声母、韵母、音调、音标和输入法首字母首声母功能。
- HanLP能够识别多音字,也能给繁体中文注拼音。
- 最重要的是,HanLP采用的模式匹配升级到AhoCorasickDoubleArrayTrie,性能大幅提升,能够提供毫秒级的响应速度!
算法详解:
- 《汉字转拼音与简繁转换的Java实现》
- # 汉字转拼音
- Pinyin = JClass("com.hankcs.hanlp.dictionary.py.Pinyin")
- text = "重载不是重任!"
- pinyin_list = HanLP.convertToPinyinList(text)
- print("原文,", end=" ")
- print(text)
- print("拼音(数字音调),", end=" ")
- print(pinyin_list)
- print("拼音(符号音调),", end=" ")
- for pinyin in pinyin_list:
- print("%s," % pinyin.getPinyinWithToneMark(), end=" ")
- print("\n拼音(无音调),", end=" ")
- for pinyin in pinyin_list:
- print("%s," % pinyin.getPinyinWithoutTone(), end=" ")
- print("\n声调,", end=" ")
- for pinyin in pinyin_list:
- print("%s," % pinyin.getTone(), end=" ")
- print("\n声母,", end=" ")
- for pinyin in pinyin_list:
- print("%s," % pinyin.getShengmu(), end=" ")
- print("\n韵母,", end=" ")
- for pinyin in pinyin_list:
- print("%s," % pinyin.getYunmu(), end=" ")
- print("\n输入法头,", end=" ")
- for pinyin in pinyin_list:
- print("%s," % pinyin.getHead(), end=" ")
- print()
- # 拼音转换可选保留无拼音的原字符
- print(HanLP.convertToPinyinString("截至2012年,", " ", True))
- print(HanLP.convertToPinyinString("截至2012年,", " ", False))

拼音转中文
HanLP中的数据结构和接口是灵活的,组合这些接口,可以自己创造新功能,我们可以使用AhoCorasickDoubleArrayTrie实现的最长分词器,需要用户调用setTrie()提供一个AhoCorasickDoubleArrayTrie
1.StringDictionary = JClass(
2."com.hankcs.hanlp.corpus.dictionary.StringDictionary")
3.CommonAhoCorasickDoubleArrayTrieSegment = JClass(
4."com.hankcs.hanlp.seg.Other.CommonAhoCorasickDoubleArrayTrieSegment")
5.Config = JClass("com.hankcs.hanlp.HanLP$Config")
6.
7.TreeMap = JClass("java.util.TreeMap")
8.TreeSet = JClass("java.util.TreeSet")
9.
10.dictionary = StringDictionary()
11.dictionary.load(Config.PinyinDictionaryPath)
12.entry = {}
13.m_map = TreeMap()
14.for entry in dictionary.entrySet():
15.pinyins = entry.getValue().replace("[\\d,]", "")
16.words = m_map.get(pinyins)
17.if words is None:
18.words = TreeSet()
19.m_map.put(pinyins, words)
20.words.add(entry.getKey())
21.words = TreeSet()
22.words.add("绿色")
23.words.add("滤色")
24.m_map.put("lvse", words)
25.
26.segment = CommonAhoCorasickDoubleArrayTrieSegment(m_map)
27.print(segment.segment("renmenrenweiyalujiangbujianlvse"))
28.print(segment.segment("lvsehaihaodajiadongxidayinji"))
1.[renmenrenweiyalujiangbujian/null, lvse/[滤色, 绿色]]
2.[lvse/[滤色, 绿色], haihaodajiadongxidayinji/null]
字符正则化
演示正规化字符配置项的效果(繁体->简体,全角->半角,大写->小写)。
该配置项位于hanlp.properties中,通过Normalization=true来开启(现在直接通过HanLP.Config.Normalization开启即可)。
切换配置后必须删除CustomDictionary.txt.bin缓存,否则只影响动态插入的新词。
在我动笔前一个星期,已经有同学添加了,添加自定义词典之后,自动删除缓存的功能。地址请参阅github.com/hankcs/HanLP/pull/954,现在只需要开启正则化即可
1.CustomDictionary =JClass("com.hankcs.hanlp.dictionary.CustomDictionary")
2.print("HanLP.Config.Normalization = False\n")
3.HanLP.Config.Normalization = False
4.CustomDictionary.insert("爱听4G", "nz 1000")
5.print(HanLP.segment("爱听4g"))
6.print(HanLP.segment("爱听4G"))
7.print(HanLP.segment("爱听4G"))
8.print(HanLP.segment("爱听4G"))
9.print(HanLP.segment("愛聽4G"))
10.
11.print(HanLP.segment("喜欢4G"))
12.print(HanLP.segment("hankcs在臺灣寫代碼"))
13.
14.print("\nHanLP.Config.Normalization = True\n")
15.HanLP.Config.Normalization = True
16.print(HanLP.segment("爱听4g"))
17.print(HanLP.segment("爱听4G"))
18.print(HanLP.segment("爱听4G"))
19.print(HanLP.segment("爱听4G"))
20.print(HanLP.segment("愛聽4G"))
21.
22.print(HanLP.segment("喜欢4G"))
23.print(HanLP.segment("hankcs在臺灣寫代碼"))
24.
25.HanLP.Config.ShowTermNature = False
27.text = HanLP.s2tw("现在的HanLP已经添加了添加自定义词典之后,自动删除缓存的功能,现在只需要开启正则化即可")
28.print(text)
29.print(HanLP.segment(text))
30.HanLP.Config.ShowTermNature = False
1.HanLP.Config.Normalization = False
2.
3.[爱听4g]
4.[爱听4G]
5.[爱, 听, 4, G]
6.[爱, 听, 4, G]
7.[愛, 聽, 4, G]
8.[喜欢, 4, G]
9.[hankcs, 在, 臺, 灣寫, 代, 碼]
10.
11.HanLP.Config.Normalization = True
12.
13.[爱听4g]
14.[爱听4g]
15.[爱听4g]
16.[爱听4g]
17.[爱听4g]
18.[喜欢, 4, g]
19.[hankcs, 在, 台湾, 写, 代码]
20.現在的HanLP已經新增了新增自定義詞典之後,自動刪除快取的功能,現在只需要開啟正則化即可
21.[现在, 的, hanlp, 已经, 新增, 了, 新增, 自定义, 词典, 之后, ,, 自动, 删除, 快, 取, 的
