Lexical chain extraction (lce) is an important research topic in the natural language processing (nlp) community, aiming to group cohesion words in a document into one cluster [].lexical chain implies the underlying structure about the texts and provides practical cues for facilitating downstream nlp tasks, e.g., text summarization [1, 18], keyword extraction. A chain is independent of the grammatical structure of the text and in effect it is a list of words that captures a portion of the cohesive structure of the text. A variable or a function that is out of scope cannot be accessed.

Examples And Observations The Term 'Lexical Set'.

Halliday’s illustration of collocation through the example of the limerick ‘a little fat man of bombay’ is both typical and memorable: A lexical chain contains a list of words which are related to each other and each word is represented as a 4tuple <term, pos, sense, rel>, where 'pos', 'sense' and 'rel'. A lexical chain holds a set of semantically related words of a text and it can be said that a lexical chain represents the semantic content of a portion of the text.
