PACTE - Collaborative electronic text annotation platform


PACTE is a collaborative annotation web platform for text content that integrates an array of practical tools for research groups. It offers two annotation modes, manual and automatic, and is available in English and French to facilitate research and collaboration. 

Manual annotation is carried out by means of an interface optimized to allow rapid entry of the data enriching a text. The automatic mode is composed of all the specialized and configurable annotation services (named entities, disambiguated terminology, etc.).

Users can interact with PACTE using the online user interface or the application programming interface API (REST API) to access all their data and facilitate algorithm development based on rich resources. 

With this collaborative web platform, analyses and annotations can be shared between users, thereby facilitating cooperation and opening the door to large-scale multi-partner studies. Using PACTE generates considerable gains in productivity by significantly reducing annotation time while facilitating the analysis of annotated data.
 

Services

 
Morphosyntactic analysis

Parse each word’s morphosyntactic function, grammatical gender, number, lemma, etc.

 
 
Document profile

Identify a document’s relevant domains through a specialized terminology lexicon.


 
Terminology disambiguation

Annotate texts using lexicon's terms that are directly related to a given field.


 
Recognize a named entity

Isolate expressions designating named entities: people, places, organizations, geopolitical entities...


 
Active learning (in development)

Train a prediction model with minimal annotation effort thanks to new algorithms selecting the examples, thus providing the best information for the model.
