motivation
Motivation
  • In text mining ,the term frequency is computed to explore the importance of the term in document.
  • However, two terms can have the same frequency in documents, but one term contributes more to the meaning of its sentences than the other term.
objectives
Objectives

Using Concept-Based Mining Model for Text Clustering , improve the clustering quality.

methodology concept based mining model1
MethodologyCONCEPT-BASED MINING MODEL

Ex:

a concept cwhich appears twice in document d in the first and the secondsentences The concept c appears fivetimes in the verb argument structures of the first sentence s 1 , and three times in the verb argument structures

of the second sentence s 2 .

ans : ctf value = (5+3)/2=4

methodology example of conceptual term frequency
MethodologyExample of Conceptual Term Frequency

. [ARG0 Texas and Australia researchers] have [TARGET created] [ARG1 industry-ready sheets of materials made from nanotubes that could lead to

the development of artificial muscles].

[ARG1 materials] [TARGET made ] [ARG2 from nanotubes that could lead

to the development of artificial muscles].

[ARG1 nanotubes] [R-ARG1 that] [ARGM-MOD could] [TARGET lead] [ARG2 to the development of artificial muscles].

MethodologyExample of Conceptual Term Frequency

1. First verb argument structure for the verb created:

. [ARG0 Texas and Australia researchers]

. [TARGET created]

. [ARG1 industry-ready sheets of materials made

from nanotubes that could lead to the development of artificial muscles].

2. Second verb argument structure for the verb made:

. [ARG1 materials]

. [TARGET made]

. [ARG2 from nanotubes that could lead to the development of artificial muscles].

3. Third verb argument structure for the verb lead:

. [ARG1 nanotubes]

. [R-ARG1 that]

. [ARGM-MOD could]

. [TARGET lead]

. [ARG2 to the development of artificial muscles].
