For a recent research paper, I plan to perform the following, for which I'd kindly ask for your advice.
I obtained a set of a few thousand job ads. I now want to analyse how and whether these job ads include 'content' that has been previously specified in another research paper as individual 'categories'. To make things more precise, there are about 15 existing categories, each of which contains descriptions that explain the category in 2-4 sentences.
Now, I want to understand, which and how many job ads cover the aspects described in each of the 15 categories. A result could be, for example, job ad #1 contains content that matches (or comes close) to the descriptions of categories 2, 5, 8 but misses content that would allow any reference to the remaining categories.
In case you got any references or advice how to approach this task, please let me know. I would suspect that the best approach would be a supervised learning approach.
