Abstract
A method and a computer-implemented system are provided for calculating an affect score for a text corpus, so as to facilitate analysis of the sentiment inherent to that text corpus. A list of a plurality of words is provided, wherein each word is expressing affect. Words in the text corpus are matched with words contained in the list, and a frequency of the matched words is computed. Affect words are associated along at least one semantic dimension, and those derived from the semantic dimensions and the respective frequencies are aggregated using a Choquet integral function into an affect score.
Claims11
A method of calculating an affect score for a text corpus, comprising the steps of:
- providing a list of a plurality of words, wherein each word is expressing affect;
- matching words in the text corpus with words contained in the list;
- computing a frequency of the matched words;
- associating affect words along at least one semantic dimension;
- and
- aggregating affect words derived from the semantic dimensions and the respective frequencies using a Choquet integral function into an affect score.
A computer-readable storage medium having computer-executable code encoded therein for calculating an affect score for a text corpus, comprising:
- a listing module configured to generate a list of a plurality of words, wherein each word is expressing affect;
- a matching module configured to match words in the text corpus with words contained in the list;
- a frequency module configured to compute a frequency of the matched words;
- an associating module configured to associate affect words along at least one semantic dimension;
- and
- an aggregating module configured to aggregate affect words derived from the semantic dimensions and the respective frequencies using a Choquet integral function into an affect score.
A computer-implemented system for calculating an affect score for a text corpus, comprising at least one readable data storage medium having computer-executable code encoded therein, the code comprising:
- a listing module configured to generate a list of a plurality of words, wherein each word is expressing affect;
- a matching module configured to match words in the text corpus with words contained in the list;
- a frequency module configured to compute a frequency of the matched words;
- an associating module configured to associate affect words along at least one semantic dimension;
- and
- an aggregating module configured to aggregate affect words derived from the semantic dimensions and the respective frequencies using a Choquet integral function into an affect score.
