        The Vulnerability Analysis App is an open-source\

        to different groups in vulnerable situations from public documents. \
        We use Natural Language Processing (NLP), specifically deep \
        learning-based text representations  to search context-sensitively \
        for mentions of the special needs of groups in vulnerable situations 
        to cluster them thematically.

    #         (a GHG target) or increase energy efficiency or renewable \
    #         energy to a specific level (a non-GHG target), typically by \ 
    #         a certain date.
    #         - **Economy-wide Target**: Certain Target are applicable \
    #             not at specific Sector level but are applicable at economic \
    #             wide scale.
    #         - **Netzero**: Identifies if its Netzero Target or not.

    #          could implement without any conditions and based on their own \
    #          resources and capabilities. A “conditional contribution” is one \
    #          that countries would undertake if international means of support \
    #          are provided, or other conditions are met.
    #         - **Action**: Actions are an intention to implement specific means of \
    #          achieving GHG reductions, usually in forms of concrete projects.
    #         - **Policies and Plans**: Policies are domestic planning documents \
    #           such as policies, regulations or guidlines, and Plans  are broader \
    #          than specific policies or actions, such as a general intention \
