Introduction
|
||||
------------
|
||||
|
||||
Senpy includes experimental support for emotion/sentiment conversion plugins.
|
||||
|
||||
|
||||
Use
|
||||
---
|
||||
|
||||
Consider the original query: `http://127.0.0.1:5000/api/?i=hello&algo=emoRand`_
|
||||
|
||||
The requested plugin (emoRand) returns emotions using Ekman's model (or big6 in EmotionML):
|
||||
|
||||
.. code:: json
|
||||
|
||||
|
||||
... rest of the document ...
|
||||
{
|
||||
"@type": "emotionSet",
|
||||
"onyx:hasEmotion": {
|
||||
"@type": "emotion",
|
||||
"onyx:hasEmotionCategory": "emoml:big6anger"
|
||||
},
|
||||
"prov:wasGeneratedBy": "plugins/emoRand_0.1"
|
||||
}
|
||||
|
||||
|
||||
|
||||
To get these emotions in VAD space (FSRE dimensions in EmotionML), we'd do this:
|
||||
|
||||
`http://127.0.0.1:5000/api/?i=hello&algo=emoRand&emotionModel=emoml:fsre-dimensions`_
|
||||
|
||||
This call, provided there is a valid conversion plugin from Ekman's to VAD, would return something like this:
|
||||
|
||||
.. code:: json
|
||||
|
||||
|
||||
... rest of the document ...
|
||||
{
|
||||
"@type": "emotionSet",
|
||||
"onyx:hasEmotion": {
|
||||
"@type": "emotion",
|
||||
"onyx:hasEmotionCategory": "emoml:big6anger"
|
||||
},
|
||||
"prov:wasGeneratedBy": "plugins/emoRand_0.1"
|
||||
}, {
|
||||
"@type": "emotionSet",
|
||||
"onyx:hasEmotion": {
|
||||
"@type": "emotion",
|
||||
"A": 7.22,
|
||||
"D": 6.28,
|
||||
"V": 8.6
|
||||
},
|
||||
"prov:wasGeneratedBy": "plugins/Ekman2VAD_0.1"
|
||||
|
||||
}
|
||||
|
||||
|
||||
That is called a *full* response, as it simply adds the converted emotion alongside.
|
||||
It is also possible to get the original emotion nested within the new converted emotion, using the `conversion=nested` parameter:
|
||||
|
||||
.. code:: json
|
||||
|
||||
|
||||
... rest of the document ...
|
||||
{
|
||||
"@type": "emotionSet",
|
||||
"onyx:hasEmotion": {
|
||||
"@type": "emotion",
|
||||
"onyx:hasEmotionCategory": "emoml:big6anger"
|
||||
},
|
||||
"prov:wasGeneratedBy": "plugins/emoRand_0.1"
|
||||
"onyx:wasDerivedFrom": {
|
||||
"@type": "emotionSet",
|
||||
"onyx:hasEmotion": {
|
||||
"@type": "emotion",
|
||||
"A": 7.22,
|
||||
"D": 6.28,
|
||||
"V": 8.6
|
||||
},
|
||||
"prov:wasGeneratedBy": "plugins/Ekman2VAD_0.1"
|
||||
}
|
||||
|
||||
}
|
||||
|
||||
|
||||
Lastly, `conversion=filtered` would only return the converted emotions.
|
||||
|
||||
Developing a conversion plugin
|
||||
------------------------------
|
||||
|
||||
Conversion plugins are discovered by the server just like any other plugin.
|
||||
The difference is the slightly different API, and the need to specify the `source` and `target` of the conversion.
|
||||
For instance, an emotion conversion plugin needs the following:
|
||||
|
||||
|
||||
.. code:: yaml
|
||||
|
||||
|
||||
---
|
||||
onyx:doesConversion:
|
||||
- onyx:conversionFrom: emoml:big6
|
||||
onyx:conversionTo: emoml:fsre-dimensions
|
||||
- onyx:conversionFrom: emoml:fsre-dimensions
|
||||
onyx:conversionTo: emoml:big6
|
||||
|
||||
|
||||
|
||||
|
||||
.. code:: python
|
||||
|
||||
|
||||
class MyConversion(EmotionConversionPlugin):

Developing new plugins
|
||||
----------------------
|
||||
This document describes how to develop a new analysis plugin. For an example of conversion plugins, see :doc:`conversion`.
|
||||
|
||||
Each plugin represents a different analysis process.There are two types of files that are needed by senpy for loading a plugin:
