OCRticle - a Structure-Aware OCR Application

Authors: Sofia G. Rodrigues dos Santos and J. João Dias de Almeida

Published in: OASIcs, Volume 113, 12th Symposium on Languages, Applications and Technologies (SLATE 2023)

Abstract
While there are currently many applications and websites capable of performing Optical Character Recognition (OCR), none of the widely available options offer structured OCR, i.e., OCR that maintains the text’s original structure. For example, if a document has a title, after performing OCR on it, the title should have a different formatting, in order to distinguish it from the rest of the text. This paper covers the topic of structure-aware OCR, first by describing the current state of OCR tools, then by showcasing a prototype tool capable of retaining the structure of articles scanned from an image.

Challenges and Opportunities in C/C++ Source-To-Source Compilation (Invited Paper)

Authors: João Bispo, Nuno Paulino, and Luís Miguel Sousa

Published in: OASIcs, Volume 107, 14th Workshop on Parallel Programming and Run-Time Management Techniques for Many-Core Architectures and 12th Workshop on Design Tools and Architectures for Multicore Embedded Computing Platforms (PARMA-DITAM 2023)

Abstract
The C/C++ compilation stack (Intermediate Representations (IR), compilation passes and backends) is encumbered by a steep learning curve, which we believe can be lowered by complementing it with approaches such as source-to-source compilation. Source-to-source compilation is a technology that is widely used and quite mature in certain programming environments, such as JavaScript, but that faces a low adoption rate in others. In the particular case of C and C++ some of the identified factors include the high complexity of the languages, increased difficulty in building and maintaining C/C++ parsers, or limitations on using source code as an intermediate representation. Additionally, new technologies such as Multi-Level Intermediate Representation (MLIR) have appeared as potential competitors to source-to-source compilers at this level. In this paper, we present what we have identified as current challenges of source-to-source compilation of C and C++, as well as what we consider to be opportunities and possible directions forward. We also present several examples, implemented on top of the Clava source-to-source compiler, that use some of these ideas and techniques to raise the abstraction level of compiler research on complex compiled languages such as C or C++. The examples include automatic parallelization of for loops, high-level synthesis optimisation, hardware/software partitioning with run-time decisions, and automatic insertion of inline assembly for fast prototyping of custom instructions.

OMT, a Web-Based Tool for Ontology Matching

Authors: João Rodrigues Gomes, Alda Lopes Gançarski, and Pedro Rangel Henriques

Published in: OASIcs, Volume 104, 11th Symposium on Languages, Applications and Technologies (SLATE 2022)

Abstract
In recent years ontologies have become an integral part of storing information in a structured and formal manner and a way of sharing said information. With this rise in usage, it was only a matter of time before different people wrote distinct ontologies to represent the same knowledge domain. The area of Ontology Matching was created with the purpose of finding correspondences between different ontologies that represented information in the same domain area. This paper starts with a study of already existing ontology matching methods in order to understand the existing techniques, focusing on the advantages and disadvantages of each one. Then, we propose an approach and an architecture to develop a new web-based tool using the knowledge acquired during the bibliographic research. The paper also includes the presentation of a prototype of the proposed tool, called OMT.

Down-Translating XML: The Python Way

Authors: Alberto Simões and José João Almeida

Published in: OASIcs, Volume 104, 11th Symposium on Languages, Applications and Technologies (SLATE 2022)

Abstract
Nowadays, the most used approach to process an XML file is based on the processing of a DOM structure and a set of operations that collects or edits information in the model using some kind of selectors (usually CSS-like or XPath). Nevertheless, the process of performing a depth-first walk through the DOM, and synthesizing values, is a simple way to traverse and transform an entire XML document. In this document we discuss the details on the implementation and usage of a Python package for XML document processing based on this structure. Given the existence of similar tools for other programming languages, we will mainly focus on the used approach, that takes advantage of the Python style guides and development patterns.

Determining Programming Languages Complexity and Its Impact on Processing

Authors: Gonçalo Rodrigues Pinto, Pedro Rangel Henriques, Daniela da Cruz, and João Cruz

Published in: OASIcs, Volume 104, 11th Symposium on Languages, Applications and Technologies (SLATE 2022)

Abstract
Tools for Programming Languages processing, like Static Analysers (for instance, a Static Application Security Testing (SAST) tool), must be adapted to cope with a different input when the source programming language changes. Complexity of the programming language is one of the key factors that deeply impact the time of giving support to it. This paper aims at proposing an approach for assessing language complexity, measuring, at a first stage, the complexity of its underlying context-free grammar (CFG). From the analysis of concrete case studies, factors have been identified that make the support process more time-consuming, in particular in the stages of language recognition and in the transformation to an abstract syntax tree (AST). In this sense, at a second stage, a set of language characteristics is analysed in order to take into account the referred factors that also impact on the language processing. The principal goal of the project here reported is to help development teams to improve the estimation of time and effort needed to cope with a new programming language. In the paper a tool is proposed, and its prototype is presented, that allows the evaluation of the complexity of a language based on a set of metrics to classify the complexity of its grammar, along with a set of properties. The tool compares the new language complexity so far determined with previously supported languages, to predict the effort to process the new language.

Reasoning with Portuguese Word Embeddings

Authors: Luís Filipe Cunha, J. João Almeida, and Alberto Simões

Published in: OASIcs, Volume 104, 11th Symposium on Languages, Applications and Technologies (SLATE 2022)

Abstract
Representing words with semantic distributions to create ML models is a widely used technique to perform Natural Language processing tasks. In this paper, we trained word embedding models with different types of Portuguese corpora, analyzing the influence of the models' parameterization, the corpora size, and domain. Then we validated each model with the classical evaluation methods available: four words analogies and measurement of the similarity of pairs of words. In addition to these methods, we proposed new alternative techniques to validate word embedding models, presenting new resources for this purpose. Finally, we discussed the obtained results and argued about some limitations of the word embedding models' evaluation methods.

Semantic Search of Mobile Applications Using Word Embeddings

Authors: João Coelho, António Neto, Miguel Tavares, Carlos Coutinho, Ricardo Ribeiro, and Fernando Batista

Published in: OASIcs, Volume 94, 10th Symposium on Languages, Applications and Technologies (SLATE 2021)

Abstract
This paper proposes a set of approaches for the semantic search of mobile applications, based on their name and on the unstructured textual information contained in their description. The proposed approaches make use of word-level, character-level, and contextual word-embeddings that have been trained or fine-tuned using a dataset of about 500 thousand mobile apps, collected in the scope of this work. The proposed approaches have been evaluated using a public dataset that includes information about 43 thousand applications, and 56 manually annotated non-exact queries. Our results show that both character-level embeddings trained on our data, and fine-tuned RoBERTa models surpass the performance of the other existing retrieval strategies reported in the literature.

Towards the Identification of Fake News in Portuguese

Authors: João Rodrigues, Ricardo Ribeiro, and Fernando Batista

Published in: OASIcs, Volume 83, 9th Symposium on Languages, Applications and Technologies (SLATE 2020)

Abstract
All over the world, many initiatives have been taken to fight fake news. Governments (e.g., France, Germany, United Kingdom and Spain), on their own way, started to take action regarding legal accountability for those who manufacture or propagate fake news. Different media outlets have also taken a multitude of initiatives to deal with this phenomenon, such as the increase of discipline, accuracy and transparency of publications made internally. Some structural changes have lately been made in said companies and entities in order to better evaluate news in general. As such, many teams were built entirely to fight fake news - the so-called "fact-checkers". These have been adopting different techniques in order to do so: from the typical use of journalists to find out the true behind a controversial statement, to data-scientists that apply forefront techniques such as text mining and machine learning to support the journalist’s decisions. Many of these entities, which aim to maintain or improve their reputation, started to focus on high standards for quality and reliable information, which led to the creation of official and dedicated departments for fact-checking. In this revision paper, not only will we highlight relevant contributions and efforts across the fake news identification and classification status quo, but we will also contextualize the Portuguese language state of affairs in the current state-of-the-art.

Assessing Factoid Question-Answer Generation for Portuguese (Short Paper)

Authors: João Ferreira, Ricardo Rodrigues, and Hugo Gonçalo Oliveira

Published in: OASIcs, Volume 83, 9th Symposium on Languages, Applications and Technologies (SLATE 2020)

Abstract
We present work on the automatic generation of question-answer pairs in Portuguese, useful, for instance, for populating the knowledge-base of question-answering systems. This includes: (i) a new corpus of close to 600 factoid sentences, manually created from an existing corpus of questions and answers, used as our benchmark; (ii) two approaches for the automatic generation of question-answer pairs, which can be seen as baselines; (iii) results of those approaches in the corpus.

Challenges and Solutions from an Embedded Programming Bootcamp

Authors: J. Pedro Amaro, Jorge Barreiros, Fernanda Coutinho, João Durães, Frederico Santos, Ana Alves, Marco Silva, and João Cunha

Published in: OASIcs, Volume 81, First International Computer Programming Education Conference (ICPEC 2020)

Abstract
Due to the proliferation of IT companies developing web and mobile applications, computer programmers are in such high demand that universities can’t satisfy it with newly graduated students. In response, some organisations started to create coding bootcamps, providing intensive full-time courses focused on unemployed people or individuals seeking for a career change. There is, however, a different set of skills that is becoming increasingly required, but is not addressed by those courses: embedded programming. In fact, the Internet of Things is connecting every device to the internet, thus making knowledge on hardware and C/C++ programming very relevant skills. A group of computer science and electrical engineering university teachers, in collaboration with several industry stakeholders, have promoted an embedded systems programming course in C and C++. This course is based on an intensive project-based approach comprising 6 months of daylong classes followed by 9 months of paid internships. After two editions, thirty embedded programmers, with no relevant previous programming experience, have been placed with the partners’ working force. In this paper, the course organisation and pedagogical methodologies are described. Problems, challenges and adopted solutions are presented and analysed. We conclude that in spite of the intense rhythm and demanding nature of the subject matter, it is possible to find the structure and solutions that keep students engaged and motivated throughout the course, allowing them to gain the required competences and successfully transition into a new career path.

Scaling up a Programmers' Profile Tool

Authors: Martinho Aragão, Maria João Varanda Pereira, and Pedro Rangel Henriques

Published in: OASIcs, Volume 74, 8th Symposium on Languages, Applications and Technologies (SLATE 2019)

Abstract
The style of programming, the proficiency on the programming language, the conciseness of the solution, the use of comments and so on, allow comparison of programmers through static analysis of their code. The Programmer Profiler Tool, which has been commonly named PP Tool, is an open source profiling tool for Java language where the programmer’s ability can be classified in one out of five possible profiles and the distinction among them falls upon the levels of both skill and readability. Taking a set of correct solutions the comparison between solutions for the same problems is fundamental to evaluate proficiency on the analysed criteria. As such, there was a need to tune the tool in order to handle, simultaneously, with a bigger amount of programs and with a wider scope of solutions. By scaling up PP Tool it will be possible to apply it in a far wider scope of situations as it will be able to cope with programmers from different geographies, with or without formal education, between 1 and 20 years of experience amongst other factors. For that, a set of features were implemented and tested and are described in this paper.

Urban Evolution of Fafe in the Last Two Centuries

Authors: João Filipe C. Lameiras, Mónica Guimarães, and Pedro Rangel Henriques

Published in: OASIcs, Volume 74, 8th Symposium on Languages, Applications and Technologies (SLATE 2019)

Abstract
Human Beings love to collect, store and preserve documents for later exploration leading to the creation of Archives. Actually, to consult municipal archives' asset, seeking information in order to explore the knowledge implicit in their documents, is the main reason for the existence of those memory institutions. On the other hand, it is known that the movement of people from dispersed living to concentration in urban environments has a strong impact both in human civilization and in the environment. This statement motivates Social Science researchers to study of urban evolution of cities. In this context and having noticed that Fafe’s Archive holds an important collection of municipal records (since XIX Century) concerning the application for authorization to construct or reconstruct private or public buildings, it came up to our minds to create a digital repository with those documents enabling their analysis. An information system shall be developed around it for information retrieval and knowledge exploration; it is also desirable that this application provides features to visualize the information extracted in convenient ways, like positioning buildings over a map. This paper discusses the development of the referred Web-based system to study the Urban Evolution of Fafe in the XIX and XX Centuries, focussing on the ontology created to understand the domain to be explored. The definition of a markup language (as a XML dialect), to annotate the Archive documents in order to enable the automatic data extraction and the semantic search, is also one of the paper topics. It will be discussed that this annotation was not defined from the scratch; instead, its design followed the ontology. It is actually an ontology-driven system. At last, the state of the Web interface (the system front-end) so far developed will be presented.
