Emotional Traits Knowledge Model


The Emotional Traits Knowledge Model (display name: Emotional Traits EN v#) classifies documents in terms of the feelings—joy, surprise, irritation, etc.—expressed in the text. They can recognize 39 different emotional traits divided into eight groups.

Mostly aimed at documents written in 1st person (tweets, messages, interviews, reviews), but not only, the model can distinguish between relatively subtle differences in emotions.

The model returns leaf categories, that is 2nd level categories like Excitement and Disillusion, but if the Output rules extra data functional option of the workflow block if turned on, it also returns the main groups of emotional traits. Main groups are the category tree groups corresponding to the most relevant emotional traits expressed in the text. They provide an easy-to-read indication of the clusters of emotional traits the text is more about, similarly to an abstract.

Category tree

Categories are divided in eight groups containing emotions with similar characteristics:

id      label       

0100    Group Rage          
0101        Anger

Output structure

The model output has the same structure as any other model and is affected by the functional options of the workflow block.
The peculiar parts of the output are the result of categorization, i.e. the categorization array, and the extraData object: to have extraData it's necessary to turn on the Output rules extra data functional option of the workflow block.

The extraData object contans the main gropus of emotional traits found in the text, for example:

"extraData": {
    "groups": [
            "id": "0500",
            "label": "Group Dejection",
            "position": 1

Each item of the group array corresponds to a group of emotional traits and has these properties:

Property Description
id Identification number or category group name in the category tree
label Group category description
position Ranking of the group

The group with the highest rank has position set to 1. Other groups, when present, have consecutive values.


Considering the following text:

We're very busy #coding a whole network manager for #unity3d based on #steamworks networking. #gamedev #indiedev #3amDeadTime #horror #game #amusement

The categorization output is:

"categories": [
        "frequency": 23.06,
        "hierarchy": [
            "Group Apprehension",
        "id": "0203",
        "label": "Fear",
        "namespace": "emotional_traits_en",
        "positions": [
                "end": 133,
                "start": 127
        "score": 3,
        "winner": true
        "frequency": 76.91,
        "hierarchy": [
            "Group Delight",
        "id": "0704",
        "label": "Amusement",
        "namespace": "emotional_traits_en",
        "positions": [
                "end": 150,
                "start": 141
        "score": 10,
        "winner": true
