Before I came here and ask for help I really really searched a lot. I saw a lot of similar questions like this but none of them helped me to solve my problem.
Here's my problem: I have a main.tex file and on this file I \input 3 other .tex files which are chapters from my document. I have a global bib file. At the end of each chapters.tex I need to add the bibliography used on it. Any help on doing this? I appreciate all help here.
The example below is not my original files but the structure is similar.
This is the main.tex:
\documentclass{article}
\usepackage[utf8]{inputenc}
\title{Runnig Example}
\author{Example}
\date{June 2020}
\usepackage[alf]{abntex2cite}
\usepackage{bibunits}
\defaultbibliography{tese}
\begin{document}
\maketitle
\input{./tex/cap_1}
\input{./tex/cap_2}
\bibliography{tese}
\end{document}
this is the cap_1.tex:
\chapter\huge{Here is the Chapters Name}
\label{cap:intro}
\begin{bibunit}
\section{Section - Introduction}
Let's cite one author here \cite{Liu2012}
After cite the first author here should only show the bibliography for those authors used on this chapter.
\putbib[tese]
\end{bibunit}
this is the cap_2.tex:
\chapter\huge{Chapters 2}
\label{cap:2}
\begin{bibunit}
\section{Section - 2}
Let's cite one author here \cite{Becker2013}
After cite the second author here should only show the bibliography for those authors used on this chapter.
\putbib[tese]
\end{bibunit}
And this is the Bibtex tese.bib:
@INPROCEEDINGS{Becker2013,
key = {Becker2013},
author = {Karin Becker and Diego Tumitan},
year = {2013},
title = {Introdução à mineração de opiniões: conceitos, aplicações e desafios},
booktitle = {SIMPÓSIO BRASILEIRO DE BANCO DE DADOS - SBBD, 28., 2013},
address = {Recife - PE}
}
@book{Liu2012,
author = {Liu, Bing},
title = {Sentiment Analysis and Opinion Mining},
year = {2012},
isbn = {1608458849},
publisher = {Morgan \& Claypool Publishers}
}
