Research on the Building Method of Domain Lexicon Combining Association Rules and Improved TF*IDF
[chapter]
2011
Lecture Notes in Electrical Engineering
Preserved Fulltext
The improved TF*IDF algorithm considers the affection of text length, feature item length, feature item location and identification of compound words on the topic extraction. ...
:To improve the efficiency and accuracy of topic words extraction in information extraction and topic words classification, a new topic lexicon building method is gradually updated and finally formed by ...
In this paper, we use the compound word recognition method based on association rules [16] , treat the foreground document collections as a transaction database. ...

On the other hand, these coding methods neither take into account the special characteristics of the images in a database nor are they suitable for fast database search. ...
Typically, one has to deal with compound structures consisting of a group of letters. Therefore, the matching criterion will be according to those compound structures. ...
This method is suitable for fast database search if the properties of each extracted compound structure are supplied. ...
