Jcseg shared in this issue is a lightweight Chinese word classifier based on mmseg algorithm, which integrates the functions of keyword extraction, key phrase extraction, key sentence extraction and automatic article summarization.

Jcseg core functionality

• Chinese word segmentation: mmseg algorithm + Jcseg original optimization algorithm, seven segmentation modes.
• Keyword extraction: based on textRank algorithm.
• Key phrase extraction: based on textRank algorithm.
• Key sentence extraction: based on textRank algorithm.
• Automatic summarization: Based on BM25+textRank algorithm.
• Automatic part-of-speech tagging: Based on thesaurus + (statistical ambiguity removal program), the current effect is not very ideal, and it is not recommended to use in applications that require high part-of-speech tagging results.
• Named entity annotation: based on thesaurus + (statistical ambiguity removal Program), email, Web address, mainland mobile phone number, place name, person name, currency, datetime time, length, area, distance unit, etc.
• Restful api: Embedded jetty provides an absolute high-performance server module, including all functions of the http interface, standardized json output format, easy to call a variety of language clients directly.

Jcseg Synonym management

1.Unified thesaurus classification:

Since version 2.2.0 jcseg has unified synonyms into a single category -CJK_SYN, you can append your synonym definitions directly to the existing synonym thesaurus
vendors/lexicons/lex-synonyms.lex can also create a separate thesaurus, classify it as a synonym thesaurus by adding the CJK_SYN definition to the first line, and then add the synonym definitions line by line or line by line in the format described below.

2.Unified synonym format:

Format: Roots, synonyms 1[/ Optional Pinyin], synonyms 2[/ Optional Pinyin],… Synonym n[/ Optional Pinyin] For example: single line definition: research, study, study, grind /yan mo, research and development of multi-line definition: (as long as the root is the same, all synonyms of the definition belong to the same set) Central one, Central one, Central one, Central one channel, Central one, Central One channel, Central one

3. Format and requirements:

1, the first word is the root term of the synonym, which must be the term that must exist in the CJK_WORD thesaurus, if it does not exist, the synonym definition will be ignored. 2, the root word is used as a distinction between different synonym sets. If two lines of synonyms define the same root word, they are automatically merged into one synonym set. 3, used in jcseg org. Lionsoul. Jcseg. SynonymsEntry to manage the collection of synonyms, every IWord entry object has a SynonymsEntry attribute to point to his collection of synonyms. 4, SynonymsEntry.rootWord stores the root word of the synonym set, and the merge of synonyms is suggested to replace the root word uniformly. 5. Except for synonyms other than the root word, jcseg will automatically detect and create the relevant IWord term object and add it to the CJK_WORD thesaurus, that is, the other synonyms do not have to be the terms existing in the CJK_WORD thesaurus. 6, other synonyms will automatically inherit the part of speech and entity definition of the root, as well as the pinyin definition of the term in the CJK_WORD lexicon (if the word exists), or the pinyin can be defined separately by adding "/ pinyin "at the end of the term. All IWord entries in the set defined by the same synonym point to the same SynonymsEntry object, that is, synonyms are automatically referenced to each other.来单独定义拼音。7，同一同义词定义的集合中的全部IWord词条都指向同一个SynonymsEntry对象，也就是同义词之间会自动相互引用。
