Hierarchical Data-Flow Graphs

Authors: José Pereira, Vitor Vieira, and Alberto Simões

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

Abstract
Data-Flows are crucial to detect the dependency of statements and expressions in a programming language program. In the context of Static Application Security Testing (SAST), they are heavily used in different aspects, from detecting tainted data to understanding code dependency. In Checkmarx, these data flows are currently computed on the fly, but their efficiency is not the desired, especially when dealing with large projects. With this in mind, a new caching mechanism is being developed, based on hierarchical graphs. In this document, we discuss the basic idea behind this approach, the challenges found and the decisions put in place for the implementation. We will also share the first insights on speed improvements for a proof of concept implementation.

Type Annotation for SAST

Authors: Marco Pereira, Alberto Simões, and Pedro Rangel Henriques

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

Abstract
Static Application Security Testing (SAST) is a type of software security testing that analyzes the source code of an application to identify security vulnerabilities and coding errors. It helps detect security vulnerabilities in software code before deployment reducing the risk of exploitation by attackers. The work presented in this document describes the work performed to upgrade Checkmarx’s SAST tool allowing the execution of vulnerability detection taking into account expression types. For this to be possible, every expression in the Document Object Model needs to have a specific type assigned accordingly to the kind of operation and to the different operand types. At the current stage, this project is already supporting the expression type annotation for three programming languages: C, C++ and C#. This support has been done through the addition of a new Resolver Rule to the Resolver stage, allowing for the generalization of languages. We also compare the complexity of writing vulnerability detection queries with or without access to type information.

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.

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.

LeMe-PT: A Medical Package Leaflet Corpus for Portuguese

Authors: Alberto Simões and Pablo Gamallo

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

Abstract
The current trend on natural language processing is the use of machine learning. This is being done on every field, from summarization to machine translation. For these techniques to be applied, resources are needed, namely quality corpora. While there are large quantities of corpora for the Portuguese language, there is the lack of technical and focused corpora. Therefore, in this article we present a new corpus, built from drug package leaflets. We describe its structure and contents, and discuss possible exploration directions.

Bootstrapping a Data-Set and Model for Question-Answering in Portuguese (Short Paper)

Authors: Nuno Ramos Carvalho, Alberto Simões, and José João Almeida

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

Abstract
Question answering systems are mainly concerned with fulfilling an information query written in natural language, given a collection of documents with relevant information. They are key elements in many popular application systems as personal assistants, chat-bots, or even FAQ-based online support systems. This paper describes an exploratory work carried out to come up with a state-of-the-art model for question-answering tasks, for the Portuguese language, based on deep neural networks. We also describe the automatic construction of a data-set for training and testing the model. The final model is not trained in any specific topic or context, and is able to handle generic documents, achieving 50% accuracy in the testing data-set. While the results are not exceptional, this work can support further development in the area, as both the data-set and model are publicly available.

Experiments on PR-Based Gamification (Short Paper)

Authors: Alberto Simões and Ricardo Queirós

Published in: OASIcs, Volume 91, Second International Computer Programming Education Conference (ICPEC 2021)

Abstract
This article documents some experiments on teaching a class on a Master Degree Program using a different perspective on gamification. Instead of winning badges or getting achievements, students earn classification points. This allows them to work as hard as they are willing, having in mind their current classification and how far they can reach. In the specific experiment being reported, students can earn final grade points with pull requests to a shared class project. The article describes the details of the experiment, extrapolates on different ideas for implementing this in other classes, and concludes with the pros and cons of such approach for student evaluation.

bOWL: A Pluggable OWL Browser (Short Paper)

Authors: Alberto Simões and Ricardo Queirós

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

Abstract
The Web Ontology Language (OWL) is a World Wide Web Consortium standard, based on the Resource Description Format standard. It is used to define ontologies. While large ontologies are useful for different applications, some tools require partial ontologies, based mostly on a hierarchical relationship of classes. In this article we present bOWL, a basic OWL browser, with the main goal of being pluggable into others, more significant, web applications. The tool was tested through its integration on LeXmart, a dictionary editing tool.

On the Nature of Programming Exercises

Authors: Alberto Simões and Ricardo Queirós

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

Abstract
There are countless reasons cited in scientific studies to explain the difficulties in programming learning. The reasons range from the subject’s complexity, the ineffective teaching and study methods, to psychological aspects such as demotivation. Still, learning programming often boils down to practice on exercise solving. Hence, it is essential to understand that the nature of a programming exercise is an important factor for the success and consistent learning. This paper explores different approaches on the creation of a programming exercise, starting with realizing how it is currently formalized, presented and evaluated. From there, authors suggest variations that seek to broaden the way an exercise is solved and, with this diversity, increase student engagement and learning outcome. The several types of exercises presented can use gamification techniques fostering student motivation. To contextualize the student with his peers, we finish presenting metrics that can be obtained by existing automatic assessment tools.

Acquiring Domain-Specific Knowledge for WordNet from a Terminological Database

Authors: Alberto Simões and Xavier Gómez Guinovart

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

Abstract
In this research we explore a terminological database (Termoteca) in order to expand the Portuguese and Galician wordnets (PULO and Galnet) with the addition of new synset variants (word forms for a concept), usage examples for the variants, and synset glosses or definitions. The methodology applied in this experiment is based on the alignment between concepts of WordNet (synsets) and concepts described in Termoteca (terminological records), taking into account the lexical forms in both resources, their morphological category and their knowledge domains, using the information provided by the WordNet Domains Hierarchy and the Termoteca field domains to reduce the incidence of polysemy and homography in the results of the experiment. The results obtained confirm our hypothesis that the combined use of the semantic domain information included in both resources makes it possible to minimise the problem of lexical ambiguity and to obtain a very acceptable index of precision in terminological information extraction tasks, attaining a precision above 89% when there are two or more different languages sharing at least one lexical form between the synset in Galnet and the Termoteca record.

Extending the Galician Wordnet Using a Multilingual Bible Through Lexical Alignment and Semantic Annotation

Authors: Alberto Simões and Xavier Gómez Guinovart

Published in: OASIcs, Volume 62, 7th Symposium on Languages, Applications and Technologies (SLATE 2018)

Abstract
In this paper we describe the methodology and evaluation of the expansion of Galnet - the Galician wordnet - using a multilingual Bible through lexical alignment and semantic annotation. For this experiment we used the Galician, Portuguese, Spanish, Catalan and English versions of the Bible. They were annotated with part-of-speech and WordNet sense using FreeLing. The resulting synsets were aligned, and new variants for the Galician language were extracted. After manual evaluation the approach presented a 96.8% accuracy.

XML Parsing in JavaScript

Authors: Alberto Simões

Published in: OASIcs, Volume 56, 6th Symposium on Languages, Applications and Technologies (SLATE 2017)

Abstract
With Web 2.0 the dynamic web got to a reality. With it, some new concepts arived, like the use of asynchronous calls to receive missing data to render a website, instead of requesting a full new page to the server. For this task, and in the recent years, developers use mostly the JSON format for the interchange of data, than XML. Nevertheless, XML is more suitable for some kind of data interchange but, and even if the web is based in SGML/XML standards, processing XML using directly JavaScript is tricky. In this document, a set of different approaches to parse XML with JavaScript will be described, and a new module, based on a set of translation functions, will be presented. At the end, a set of experiments will be discussed, trying to evaluate how versatile the proposed approach is.

SOS - Simple Orchestration of Services

Authors: Ricardo Queirós and Alberto Simões

Published in: OASIcs, Volume 56, 6th Symposium on Languages, Applications and Technologies (SLATE 2017)

Abstract
Nowadays, we continue to write redundant code which can often be reused from the Web. Reusing programming tasks is beneficial since it speeds up the process of creating applications and reduces the errors related with the task creation from scratch. At the same time, the demands of our applications are increasing, leading to a simple problem having to be solved through several tasks. With the advent of the cloud, there are countless Web services that proliferate on the Web. One solution for developers is to use these Web Services. However, the process of mastering and coordinating all these services manually is time-consuming and error-prone. This paper presents SOS, a Simple Orchestration of Services. The ultimate goal of this tool is to act as a service composer while promoting the separation of concerns for two typical actors in this realm: the developer and the business analyst. The developer must define a service as a SOS task based on a JSON schema and submit it in a Web specialized editor. The business analyst uses the SOS editor, in an interactive way, to chain the required tasks to solve a specific problem. Then, the developer, uses a a simple client API - a SOS engine wrapper - to load a SOS manifest and to iterate over all tasks, without the need to dominate any bureaucratic aspects related with HTTP clients and messages. As a case study, several tasks are instantiated and aggregated in order to generate a composite service for a mobile app whose goal is to give an translated description of a picture taken with a mobile phone.

Sni'per: a Code Snippet RESTful API

Authors: Ricardo Queirós and Alberto Simões

Published in: OASIcs, Volume 51, 5th Symposium on Languages, Applications and Technologies (SLATE'16) (2016)

Abstract
Today we use the Web for almost everything, even to program. There are several specialized code editors gravitating on the Web and emulating most of the features inherited from traditional IDEs, such as, syntax highlight, code folding, autocompletion and even code refactorization. One of the techniques to speed the code development is the use of snippets as predefined code blocks that can be automatically included in the code. Although several Web editors support this functionality, they come with a limited set of snippets, not allowing the contribution of new blocks of code. Even if that would be possible, they would be available only to the code's owner or to the editors' users through a private cloud repository. This paper describes the design and implementation of Sni'per, a RESTful API that allows public access for multi-language programming code-blocks ordered by popularity. Besides being able to access code snippets from other users and score them, we can also contribute with our own snippets creating a global network of shared code. In order to make coding against this API easier, we create a client library that reduces the amount of code required to write and make the code more robust.

Building a Dictionary using XML Technology

Authors: Alberto Simões, José João Almeida, and Ana Salgado

Published in: OASIcs, Volume 51, 5th Symposium on Languages, Applications and Technologies (SLATE'16) (2016)

Abstract
In this article we describe the workflow implemented to convert a dictionary saved as a PDF file into an XML document and posterior importation into an XML aware database, and the process to edit, add and delete new entries. The conversion process was challenging given the format of the PDF file, and the fine grained detail of the XML schema that was used. For that, an iterative filtering approach was used. To store the dictionary we decided to use an XML aware database (eXist-DB), that stores each dictionary entry as a separate resource. It can be queried used a web interface developed using XQuery. The lexicographers can edit entries using the oXygen XML editor, reading and storing them directly in the database. In order to guarantee incremental backups, it was defined a mechanism to import the XML database into a GIT repository. Finally, a couple of programs were created in order to prepare regular reports on the dictionary revision process, as well as to backup it in a GIT repository.

Language Identification: a Neural Network Approach

Authors: Alberto Simões, José João Almeida, and Simon D. Byers

Published in: OASIcs, Volume 38, 3rd Symposium on Languages, Applications and Technologies (2014)

Abstract
One of the first tasks when building a Natural Language application is the detection of the used language in order to adapt the system to that language. This task has been addressed several times. Nevertheless most of these attempts were performed a long time ago when the amount of computer data and the computational power were limited. In this article we analyze and explain the use of a neural network for language identification, where features can be extracted automatically, and therefore, easy to adapt to new languages. In our experiments we got some surprises, namely with the two Chinese variants, whose forced us for some language-dependent tweaking of the neural network. At the end, the network had a precision of 95%, only failing for the Portuguese language.

Abstract
The success of the humankind relies on our ability to communicate and transform the world. For ages we developed tools and technologies that allowed us to thrive and prosper. As we expanded to every corner of the planet we created languages that enabled us to communicate and record knowledge, even if they also become barriers to communication in themselves. Technology and language have always been interconnected. Technologies to record language gave birth to history and the written language allowed us to preserve knowledge, including knowledge on technologies. Technology reshaped language as books, radio shows or motion pictures made us aware of how other people communicate. But technologies and language were not completely blend together until computers and networks become our favourite tool to communicate and transform the world. The goal of the Symposium on Languages, Applications and Technologies (SLATE) is to be a forum to discuss the different ways in which language and technology interplay in computer science, and they are many. The symposium is divided into three main tracks, each one focusing a specific aspect of languages, from natural languages to compilers. * The HHL (Human-Human Languages) track is dedicated to the discussion of research projects and ideas involving natural language processing and their industrial application. * The HCL (Human-Computer Languages) track is where researchers, developers and educators exchange ideas and information on the latest academic or industrial work on language design, processing, assessment and applications. * The CCL (Computer-Computer Languages) track main goal is to provide a broad space for discussion about the XML markup language, examples of usage and associated technologies. SLATE follows the footsteps of two former conferences: CoRTA, the Conference on Compilers, Related Technologies and Applications; and XATA, the conference on XML, Applications and Applied Technologies, both with more than a decade of history. This volume contains the proceedings of the 2nd edition of SLATE, held in the Department of Computer Science, Faculty of Sciences, University of Porto, Portugal, during June 20-21, 2013. This year, SLATE received a total of 26 paper submissions for the three tracks. Each submission was reviewed by at least three Program Committee members, which included 55 researchers (counting sub-reviewers). At the end, 19 papers were selected for publication and presentation at the symposium, resulting in a 27% rejection rate. The set of accepted papers present a variety of contributions and were divided into the following five sessions for presentation at the symposium: * Software Development Tools, includes four articles on programming languages compilation and analysis; * XML and Applications, includes four articles on the usage of XML in different areas, ranging from the annotation of documents to its use on the semantic web; * Languages on Learning Environments, includes three articles that focus the automation on exercises generation and evaluation; * Domain Specific Languages, includes four articles on languages for specific languages, from music, robots or graphical user interfaces; * Natural Language Processing, includes four articles related to processing and teaching natural languages. In addition to these sessions, the program also included two keynote presentations, one on the PICAT system, a scalable logic-based language, by Neng-Fa Zhou (Brooklyn College, New York), and another on software languages and their history, by Jean-Marie Favre (University of Grenoble, France). The organizers of SLATE 2013 are in debt to many people without whom this event would never been possible. We wish to thank to our sponsors for making this event possible and to the EasyChair conference management system for simplifying our task. Thanks must go also to the authors of all submitted papers for their contribution and interest in the symposium and to the participants for making the event a meeting point for a fruitful exchange of ideas and feedback on recent developments. Finally, we want to express our gratitude to the Program Committee members and sub-reviewers, as the symposium would not have been possible without their dedicated time and knowledge in evaluating and ranking so many submissions from so many different topics. To all, our deepest thanks!

Retreading Dictionaries for the 21st Century

Authors: Xavier Gómez Guinovart and Alberto Simões

Published in: OASIcs, Volume 29, 2nd Symposium on Languages, Applications and Technologies (2013)

Abstract
Even in the 21st century, paper dictionaries are still compiled and developed using standard word processors. Many publishing companies are, nowadays, working on converting their dictionaries into computer readable documents, so that they can be used to prepare new features, such as making them available online. Luckily, most of these publishers can pay review teams to fix and even enhance these dictionaries. Unfortunately, research institutions cannot hire that amount of workers. In this article we present the process of retreading a Galician dictionary that was first developed and compiled using Microsoft Word. This dictionary was converted, through automatic rewriting, into a Text Encoding Initiative schema subset. This process will be detailed, and the problems found will be discussed. Given a recent normative that changed the Galician orthography, the dictionary has undergone a semi-automatic modernization process.

Dictionary Alignment by Rewrite-based Entry Translation

Authors: Alberto Simões and Xavier Gómez Guinovart

Published in: OASIcs, Volume 29, 2nd Symposium on Languages, Applications and Technologies (2013)

Abstract
In this document we describe the process of aligning two standard monolingual dictionaries: a Portuguese language dictionary and a Galician synonym dictionary. The main goal of the project is to provide an online dictionary that can show, in parallel, definitions and synonyms in Portuguese and Galician for a specific word, written in Portuguese or Galician. These two languages are very close to each other, and that is the main reason we expect this idea to be viable. The main drawback is the lack of a good and free translation dictionary between these two languages, namely, a dictionary that can cover lexicons with more than one hundred thousand different words. To solve this issue we defined a translation function, based on substitutions, that is able to achieve an F_1 score of 0.88 on a manually verified dictionary of nine thousand words. Using this same translation function to align a Portuguese--Galician dictionary we obtained almost 50% of the dictionary lexicon (more than eighty thousand words) alignment.

Generating flex Lexical Scanners for Perl Parse::Yapp

Authors: Alberto Simões, Nuno Ramos Carvalho, and José João Almeida

Published in: OASIcs, Volume 21, 1st Symposium on Languages, Applications and Technologies (2012)

Abstract
Perl is known for its versatile regular expressions. Nevertheless, using Perl regular expressions for creating fast lexical analyzer is not easy. As an alternative, the authors defend the automated generation of the lexical analyzer in a well known fast application (flex) based on a simple Perl definition in the syntactic analyzer. In this paper we extend the syntax used by Parse::Yapp, one of the most used parser generators for Perl, making the automatic generation of flex lexical scanners possible. We explain how this is performed and conclude with some benchmarks that show the relevance of the approach.
