+Architecture
+============
+
+The main component of a sentiment analysis service is the algorithm itself. However, for the algorithm to work, it needs to get the appropriate parameters from the user, format the results according to the defined API, interact with the user whn errors occur or more information is needed, etc.
+
+Senpy proposes a modular and dynamic architecture that allows:
+
+* Implementing different algorithms in a extensible way, yet offering a common interface.
+* Offering common services that facilitate development, so developers can focus on implementing new and better algorithms.
+
+The framework consists of two main modules: Senpy core, which is the building block of the service, and Senpy plugins, which consist of the analysis algorithm. The next figure depicts a simplified version of the processes involved in an analysis with the Senpy framework.

-emoTextANEW plugin
-******************
-
-This plugin is going to used the ANEW lexicon dictionary to calculate de VAD (valence-arousal-dominance) of the sentence and the determinate which emotion is closer to this value.
-
-Each emotion has a centroid, which it has been approximated using the formula described in 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.
-
-emoTextWAF plugin
-*****************
-
-This plugin uses WordNet-Affect (http://wndomains.fbk.eu/wnaffect.html) to calculate the percentage of each emotion. The emotions that are going to be used are: anger, fear, disgust, joy and sadness. It is has been used a emotion mapping enlarge the emotions:

-sentiText plugin
-****************
-
-This plugin is based in the classifier developed for the TASS 2015 competition. It has been developed for Spanish and English. The different phases that has this plugin when it is activated:
-
-* Train both classifiers (English and Spanish).
-* Initialize resources (dictionaries,stopwords,etc.).
-* Extract bag of words,lemmas and chars.
-
-Once the plugin is activated, the features that are going to be extracted for the classifiers are:
-
-* Matches with the bag of words extracted from the train corpus.
-* Sentiment score of the sentences extracted from the dictionaries (lexicons and emoticons).
-* Identify negations and intensifiers in the sentences.
-* Complementary features such as exclamation and interrogation marks, eloganted and caps words, hashtags, etc.
-
-The plugin has a preprocessor, which is focues on Twitter corpora, that is going to be used for cleaning the text to simplify the feature extraction.

 ----------------------
 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:
+A more step-by-step tutorial with slides is available `here <https://lab.cluster.gsi.dit.upm.es/senpy/senpy-tutorial>`__ 
 
-- Definition file, has the ".senpy" extension.
+What is a plugin?
-- Code file, is a python file.
+=================
 
-This separation will allow us to deploy plugins that use the same code but employ different parameters.
+A plugin is a program that, given a text, will add annotations to it.
+In practice, a plugin consists of at least two files:
+
+- Definition file: a `.senpy` file that describes the plugin (e.g. what input parameters it accepts, what emotion model it uses).
+- Python module: the actual code that will add annotations to each input.
+
+This separation allows us to deploy plugins that use the same code but employ different parameters.
 For instance, one could use the same classifier and processing in several plugins, but train with different datasets.
 This scenario is particularly useful for evaluation purposes.
 
 The only limitation is that the name of each plugin needs to be unique.
 
-Plugins Definitions
+Plugin Definition files
-===================
+=======================
 
 The definition file contains all the attributes of the plugin, and can be written in YAML or JSON.
+When the server is launched, it will recursively search for definition files in the plugin folder (the current folder, by default).
 The most important attributes are:
 
 * **name**: unique name that senpy will use internally to identify the plugin.
 * **module**: indicates the module that contains the plugin code, which will be automatically loaded by senpy.
 * **version**
-* extra_params: used to specify parameters that the plugin accepts that are not already part of the senpy API. Those parameters may be required, and have aliased names. For instance:

 Plugins are loaded asynchronously, so don't worry if the activate method takes too long. The plugin will be marked as activated once it is finished executing the method.
 
+Entries
+=======
+
+Entries are objects that can be annotated.
+By default, entries are `NIF contexts <http://persistence.uni-leipzig.org/nlp2rdf/ontologies/nif-core/nif-core.html>`_ represented in JSON-LD format.
+Annotations are added to the object like this:

+   entry['annotationNameURI'] = 'myvalue'

 What is Senpy?
 --------------
 
-Senpy is an open source reference implementation of a linked data model for sentiment and emotion analysis services based on the vocabularies NIF, Marl and Onyx. 
+Senpy is a framework that turns your sentiment or emotion analysis algorithm into a full blown semantic service.
+Senpy takes care of:
 
-The overall goal of the reference implementation Senpy is easing the adoption of the proposed linked data model for sentiment and emotion analysis services, so that services from different providers become interoperable. With this aim, the design of the reference implementation has focused on its extensibility and reusability. 
+  * Interfacing with the user: parameter validation, error handling.
+  * Formatting: JSON-LD, Turtle/n-triples input and output, or simple text input
+  * Linked Data: senpy results are semantically annotated, using a series of well established vocabularies, and sane default URIs.
+  * User interface: a web UI where users can explore your service and test different settings
+  * A client to interact with the service. Currently only available in Python.
 
-A modular approach allows organizations to replace individual components with custom ones developed in-house. Furthermore, organizations can benefit from reusing prepackages modules that provide advanced functionalities, such as algorithms for sentiment and emotion analysis, linked data publication or emotion and sentiment mapping between different providers.
+Sharing your sentiment analysis with the world has never been easier!
 
-Specifications
+Senpy for service developers
-==============
+============================
 
-The model used in Senpy is based on the following specifications:
+Check out the :doc:`plugins` if you have developed an analysis algorithm (e.g. sentiment analysis) and you want to publish it as a service.
 
-* Marl, a vocabulary designed to annotate and describe subjetive opinions expressed on the web or in information systems.
+Senpy for end users
-* Onyx, which is built one the same principles as Marl to annotate and describe emotions, and provides interoperability with Emotion Markup Language.
+===================
-* NIF 2.0, which defines a semantic format and APO for improving interoperability among natural language processing services
 
-Architecture
+All services built using senpy share a common interface.
-============
+This allows users to use them (almost) interchangeably.
+Senpy comes with a :ref:`built-in client`.
 
-The main component of a sentiment analysis service is the algorithm itself. However, for the algorithm to work, it needs to get the appropriate parameters from the user, format the results according to the defined API, interact with the user whn errors occur or more information is needed, etc.
 
-Senpy proposes a modular and dynamic architecture that allows:
+.. toctree::

+ 
+    architecture
 
-* Implementing different algorithms in a extensible way, yet offering a common interface.
-* Offering common services that facilitate development, so developers can focus on implementing new and better algorithms.
-
-The framework consists of two main modules: Senpy core, which is the building block of the service, and Senpy plugins, which consist of the analysis algorithm. The next figure depicts a simplified version of the processes involved in an analysis with the Senpy framework.
