A chatbot is a software agent that mimics human conversation using artificial intelligence technologies. Chatbots help to accomplish tasks ranging from answering questions, playing music, to managing smart home devices. The adoption of this kind of agent is increasing since people are discovering the benefits of them, such as saving time and money, higher customer satisfaction, customer base growing, among others. However, developing a chatbot is a challenging task that requires addressing several issues such as pattern matching, natural language understanding, and natural language processing, as well as to design a knowledge base that encapsulates the intelligence of the system. This chapter describes the design and implementation of a text/speech chatbot for supporting health self-management. This chatbot is currently based on Spanish. The main goal of this chapter is to clearly describe the main components and phases of the chatbot development process, the methods, and tools used for this purpose, as well as to describe and discuss our findings from the practice side of things.

Sekolah Tinggi Ilmu Manajemen Informatika dan Komputer (STMIK) Dharma Wacana memiliki beberapa bagian seperti Bagian Administrasi Akademik yang memiliki tugas melaksanakan pelayanan dibidang akademik. Bagian Administrasi Akademik menjadi sumber informasi terkait kegiatan perkuliahan. Kebutuhan informasi perkuliahan belum efektif dikarenakan terbatasnya jam kerja dari pegawai dan masih banyak pertanyaan berulang yang berdatangan ke Bagian Administrasi Akademik, seperti pertanyaan yang telah ditanyakan oleh seorang mahasiswa kemudian ditanyakan lagi oleh mahasiswa lainnya. Tujuan dari penelitian ini adalah melakukan observasi dan wawancara terhadap mahasiswa dan pegawai Bagian Administrasi Akademik serta menganalisis kelemahannya sehingga dapat menjadi acuan untuk merancang aplikasi dengan penerapan Natural Language Processing (NLP). Pada penelitian telah dibangun Virtual Assistant berupa Chatbot yang tersedia pada platform messenger yaitu LINE, Facebook dan Telegram yang hanya bertindak layaknya bagian informasi perkuliahan. NLP dengan pendekatan pattern matching menggunakan regular expression diterapkan dalam proses mengenali pertanyaan mahasiswa sehingga Virtual Assistant dapat memberikan jawaban yang sesuai.

Natural Language Processing for under-resourced languages is now a mainstream research area. However, there are limited studies on Natural Language Processing applications for many indigenous East African languages. As a contribution to covering the current gap of knowledge, this paper focuses on evaluating the application of well-established machine translation methods for one heavily under-resourced indigenous East African language called Lumasaaba. Specifically, we review the most common machine translation methods in the context of Lumasaaba including both rule-based and data-driven methods. Then we apply a state of the art data-driven machine translation method to learn models for automating translation between Lumasaaba and English using a very limited data set of parallel sentences. Automatic evaluation results show that a transformer-based Neural Machine Translation model architecture leads to consistently better BLEU scores than the recurrent neural network-based models. Moreover, the automatically generated translations can be comprehended to a reasonable extent and are usually associated with the source language input.

In 2018, we overheard many CEEA-AGEC members stating that they have "found their people"; this led us to wonder what makes this evolving community unique. Using cultural historical activity theory to view the proceedings of CEEA-ACEG 2004-2018 in comparison with the geographically and intellectually adjacent ASEE, we used both machine-driven (Natural Language Processing, NLP) and human-driven (literature review of the proceedings) methods. Here, we hoped to build on surveys—most recently by Nelson and Brennan (2018)—to understand, beyond what members say about themselves, what makes the CEEA-AGEC community distinct, where it has come from, and where it is going. Engaging in the two methods of data collection quickly diverted our focus from an analysis of the data themselves to the characteristics of the data in terms of cultural historical activity theory. Our preliminary findings point to some unique characteristics of machine- and human-driven results, with the former, as might be expected, focusing on the micro-level (words and language patterns) and the latter on the macro-level (ideas and concepts). NLP generated data within the realms of "community" and "division of labour" while the review of proceedings centred on "subject" and "object"; both found "instruments," although NLP with greater granularity. With this new understanding of the relative strengths of each method, we have a revised framework for addressing our original question.

The main advantage of modern natural language processing methods is a possibility to turn an amorphous human-readable task into a strict mathematic form. That allows to extract chemical data and insights from articles and to find new semantic relations. We propose a universal engine for processing chemical and biological texts. We successfully tested it on various use-cases and applied to a case of searching a therapeutic agent for a COVID-19 disease by analyzing PubMed archive.
