Relevancy of a word
Every word we understand has a meaning to us in one or many subjects. The relevancy of a word to a subject may differ from person to person, according to their subject interest. But we are going to describe this for all the people generally.
This is basically about mapping the relationship between…
Word ==> Subject
As there are many subjects we are interested on we have to represent this in 1:N One to many database. But for the efficiency we have a second thought to use a flat file where there is a matrix.
Why we are going to use a matrix is that we are going to map the Relevancy of a Word to a Subject. Actually the arrow in the above diagram will contain a numerical value for that. We put a Weight for the relevancy.
For an example the word “Car” will be 100% relevant to the subject “Automobile” and 0% relevant to “Art” or “Education” and the Word “Pizza” will be 100% relevant for the subject “Food” and 0% for “Science”
