          <p>
            Our web application nopaque combines coordinated tools such as Optical
            Character Recognition (OCR), Natrual Language Processing (NLP) and a
            powerful Keyword In Context Search (KWIC) with the CQP query language.
          </p>
          <br>
          <p>
            nopaque offers the possibility to use all tools individually or as a
            workflow. All work steps are coordinated in such a way that individual
            services can be used on top of each other. The platform supports
            researchers in converting their files into formats that can be further
            processed, automatically enriching them with information and then
            analyzing them, so that nopaque maps a large part of the research
            processes in the humanities. With this toolbox we address researchers
            in the humanities from all disciplines and levels of knowledge.
            The data generated during the processes can be downloaded after each
            step in order to evaluate or further process them with other (external) tools.

              <p>
                <em>nopaque</em> is developed by a small, interdisciplinary Team at
                <em>University Bielefeld</em> called <em>Data Infrastructure and
                Digital Humanities (INF)</em>. We are part of the <em>SFB 1288 -

                Yes nopaque is free to use for everyone! It does not matter if you
                are a researcher in the humanities, a student or just someone who
                wants to learn something new. Just <a href="http://nopaque.localhost/auth/register">

          <div class="collapsible-body">
            <span>We just think that nopaque with a lower case first letter looks
              better than Nopaque with an upper case first letter. Simple as that!

          <div class="collapsible-body">
            <span>
              <p>
                When we started developing nopaque we wanted to have a cool name
                like <a href="https://voyant-tools.org/">voyant</a> which can be translated
                to light or seeing. So we choose opaque thinking that it means that
                something is transparent. After a while we realized that we misunderstood
                the meaning of the word (opaque means non-transparent) and simply
                negated it ending up with nopaque.
              </p>
              <p>
                We also think nopaque fits pretty nicley because we want you to be
                able to make your texts transparent and see through them with our
                analysis tool to gain knew knowledge about them.

            <span>Yes nopaque only uses free and open source software (FOSS). You

                nopaques frontend (what the user sees) is written in HTML 5
                and Javascript. The backend (stuff that happens on our servers)
                is realized with <a href="https://palletsprojects.com/p/flask/">
                Flask</a>, a python based lightweight WSGI web application
                framework. We utilize <a href="https://www.docker.com/">Docker</a>
                to easily deploy nopaque on our servers.
              </p>
              <p>
                The client server real time comminication is implemented using

              <p>Every service (e.g. OCR or NLP) provided by nopaque is using
                established opensource software. Take a look at their related

                NLP stands for natural language processing wich is a subfield of

                with the interactions between computers and human language.
                For example nopaque uses spaCy to automtically tag every word with
                its part of speech tag which describes its grammatical property.
