# Senpy Plugin for Sentiment and Emotion
|
|
||||||
|
|
||||||
This plugin allows to choose sentiment and emotion plugins to retrieve a response with the total sentiment and emotion analysis.
|
|
||||||
|
|
||||||
You can adjust the parameters of the plugin as follows:
|
|
||||||
|
|
||||||
- Sentiments plugins: emotion-wnaffect, emotion-anew(only english)
|
|
||||||
- Emotions plugins: sentiment-tass, sentiment-vader,sentiment-meaningCloud(requires API KEY)
|
|
||||||
- Endpoint: the endpoint where the used plugins are. (default: http://senpy.cluster.gsi.dit.upm.es/api/)
|
|
||||||
- Language: english(en) or spanish(es)

# Plugin emotion-anew
|
|
||||||
|
|
||||||
This plugin consists on an **emotion classifier** that detects six possible emotions:
|
|
||||||
- Anger : general-dislike.
|
|
||||||
- Fear : negative-fear.
|
|
||||||
- Disgust : shame.
|
|
||||||
- Joy : gratitude, affective, enthusiasm, love, joy, liking.
|
|
||||||
- Sadness : ingrattitude, daze, humlity, compassion, despair, anxiety, sadness.
|
|
||||||
- Neutral: not detected a particulary emotion.
|
|
||||||
|
|
||||||
The plugin uses **ANEW lexicon** dictionary to calculate VAD (valence-arousal-dominance) of the sentence and determinate which emotion is closer to this value. To do this comparision, it is defined that each emotion has a centroid, calculated according to this article: http://www.aclweb.org/anthology/W10-0208.
|
|
||||||
|
|
||||||
The plugin is going to look for the words in the sentence that appear in the ANEW dictionary and calculate the average VAD score for the sentence. Once this score is calculated, it is going to seek the emotion that is closest to this value.
|
|
||||||
|
|
||||||
The response of this plugin uses [Onyx ontology](https://www.gsi.dit.upm.es/ontologies/onyx/) developed at GSI UPM, to express the information.
|
|
||||||
|
|
||||||
##Usage

# WordNet-Affect plugin
|
|
||||||
|
|
||||||
This plugin uses WordNet-Affect (http://wndomains.fbk.eu/wnaffect.html) to calculate the percentage of each emotion. The plugin classifies among five diferent emotions: anger, fear, disgust, joy and sadness. It is has been used a emotion mapping enlarge the emotions:
|
|
||||||
|
|
||||||
- anger : general-dislike
|
|
||||||
- fear : negative-fear
|
|
||||||
- disgust : shame
|
|
||||||
- joy : gratitude, affective, enthusiasm, love, joy, liking
|
|
||||||
- sadness : ingrattitude, daze, humlity, compassion, despair, anxiety, sadness
|
|
||||||
|
|
||||||
## Usage
|
|
||||||
|
|
||||||
The parameters accepted are:
|
|
||||||
|
|
||||||
- Language: English (en).
|
|
||||||
- Input: Text to analyse.
|
|
||||||
|
|
||||||
Example request:
|
|
||||||
```
|
|
||||||
http://senpy.cluster.gsi.dit.upm.es/api/?algo=emotion-wnaffect&language=en&input=I%20love%20Madrid
|
|
||||||
```
|
|
||||||
|
|
||||||
Example respond: This plugin follows the standard for the senpy plugin response. For more information, please visit [senpy documentation](http://senpy.readthedocs.io). Specifically, NIF API section.
|
|
||||||
|
|
||||||
|
|
||||||
The response of this plugin uses [Onyx ontology](https://www.gsi.dit.upm.es/ontologies/onyx/) developed at GSI UPM for semantic web.
|
|
||||||
|
|
||||||
This plugin uses WNAffect labels for emotion analysis.
|
|
||||||
|
|
||||||
The emotion-wnaffect.senpy file can be copied and modified to use different versions of wnaffect with the same python code.
|
|
||||||
|
|
||||||
|
|
||||||
## Known issues
|
|
||||||
|
|
||||||
- This plugin uses the pattern library, which means it will only run on python 2.7
|
|
||||||
- Wnaffect and corpora files are not included in the repository, but can be easily added either to the docker image (using a volume) or in a new docker image.
|
|
||||||
- You can download Wordnet 1.6 here: <http://wordnetcode.princeton.edu/1.6/wn16.unix.tar.gz> and extract the dict folder.
|
|
||||||
- The hierarchy and synsets files can be found here: <https://github.com/larsmans/wordnet-domains-sentiwords/tree/master/wn-domains/wn-affect-1.1>

# Sentiment basic plugin
|
|
||||||
|
|
||||||
This plugin is based on the classifier developed for the TASS 2015 competition. It has been developed for Spanish and English. This is a demo plugin that uses only some features from the TASS 2015 classifier. To use the entirely functional classifier you can use the service in: http://senpy.cluster.gsi.dit.upm.es
|
|
||||||
|
|
||||||
There is more information avaliable in:
|
|
||||||
|
|
||||||
- Aspect based Sentiment Analysis of Spanish Tweets, Oscar Araque and Ignacio Corcuera-Platas and Constantino Román-Gómez and Carlos A. Iglesias and J. Fernando Sánchez-Rada. http://gsi.dit.upm.es/es/investigacion/publicaciones?view=publication&task=show&id=376
|
|
||||||
|
|
||||||
## Usage
|
|
||||||
Params accepted:
|
|
||||||
|
|
||||||
- Language: Spanish (es).
|
|
||||||
- Input: text to analyse.
