Large Language Models: Compilers for the 4^{th} Generation of Programming Languages? (Short Paper)

Authors: Francisco S. Marcondes, José João Almeida, and Paulo Novais

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


Abstract
This paper explores the possibility of large language models as a fourth generation programming language compiler. This is based on the idea that large language models are able to translate a natural language specification into a program written in a particular programming language. In other words, just as high-level languages provided an additional language abstraction to assembly code, large language models can provide an additional language abstraction to high-level languages. This interpretation allows large language models to be thought of through the lens of compiler theory, leading to insightful conclusions.

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.

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.

A Teaching Assistant for the C Language (Short Paper)

Authors: Rui C. Mendes and José João Almeida

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


Abstract
We introduce a C tutor that can help instructors manage classes with many students learning to program in C. Nowadays, it is easy to evaluate code but it is hard to provide good feedback. We introduce a tool to help instructors provide students with feedback concerning their implementation and documentation for honing their programming skills. This tool is implemented in Python and is available at https://github.com/rcm/C_teaching_assistant.

BhTSL, Behavior Trees Specification and Processing

Authors: Miguel Oliveira, Pedro Mimoso Silva, Pedro Moura, José João Almeida, and Pedro Rangel Henriques

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


Abstract
In the context of game development, there is always the need for describing behaviors for various entities, whether NPCs or even the world itself. That need requires a formalism to describe properly such behaviors. As the gaming industry has been growing, many approaches were proposed. First, finite state machines were used and evolved to hierarchical state machines. As that formalism was not enough, a more powerful concept appeared. Instead of using states for describing behaviors, people started to use tasks. This concept was incorporated in behavior trees. This paper focuses in the specification and processing of Behavior Trees. A DSL designed for that purpose will be introduced. It will also be discussed a generator that produces LaTeX diagrams to document the trees, and a Python module to implement the behavior described. Additionally, a simulator will be presented. These achievements will be illustrated using a concrete game as a case study.

Musikla: Language for Generating Musical Events

Authors: Pedro Miguel Oliveira da Silva and José João Almeida

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


Abstract
In this paper, we'll discuss a simple approach to integrating musical events, such as notes or chords, into a programming language. This means treating music sequences as a first class citizen. It will be possible to save those sequences into variables or play them right away, pass them into functions or apply operators on them (like transposing or repeating the sequence). Furthermore, instead of just allowing static sequences to be generated, we'll integrate a music keyboard system that easily allows the user to bind keys (or other kinds of events) to expressions. Finally, it is important to provide the user with multiple and extensible ways of outputing their music, such as synthesizing it into a file or directly into the speakers, or writing a MIDI or music sheet file. We'll structure this paper first with an analysis of the problem and its particular requirements. Then we will discuss the solution we developed to meet those requirements. Finally we'll analyze the result and discuss possible alternative routes we could've taken.

eOS: The Exercise Operating System

Authors: Rui Mendes and José João Almeida

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


Abstract
We present an architecture for a system for creating, adapting and evaluating programming exercises for students. The system is capable of generating exercise skeletons, automatically creating inputs and outputs, provide a way of creating a large number of exercises programmatically and allowing students to solve them while giving them feedback. Furthermore, it allows the creation of special comparators that can check whether the output of a given submission is equivalent to the expected one or simply check whether the above mentioned output corresponds to a correct solution.

Abcl: Abc music notation with rich chord support (Short Paper)

Authors: José João Almeida

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


Abstract
It is well known the relevance of accompany chords but there is a lack of tools capable of automatically generating sound from them. In this paper we describe a domain specific language (Abcl) aimed to be a prototyping environment for new experimental music operators. Currently Abcl: (1) adds support for accompany chords (chordmode, instruments, chord-lines); (2) adds clearer support for percussion (drums, drum-machine) (3) adds a support for variables and functions. Abcl tool is a syntactic-preprocessor that produces Abc. The DSLToolkit, used to create Abcl, is also briefly presented and discussed in the paper.

Predicting Performance Problems Through Emotional Analysis (Short Paper)

Authors: Ricardo Martins, José João Almeida, Pedro Rangel Henriques, and Paulo Novais

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


Abstract
In the cartoons, every time a character is nervous he/she begins to count to ten to keep calm. This is a technique, among hundreds, that helps to control the emotional state. However, what would be the impact if the emotions would not be controlled? Are the emotions important in terms of impairing the ability to perform tasks correctly? Using a case study of typing text, this paper is about a process to predict the number of writing errors from a person based on the emotional state and some characteristics of the writing process. Using preprocessing techniques, lexicon-based approaches and machine learning, we achieved a percentage of 80% of correct values, when considering the emotional profile on the writing style.

Context-Free Grammars: Exercise Generation and Probabilistic Assessment

Authors: José João Almeida, Eliana Grande, and Georgi Smirnov

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


Abstract
In this paper we present a metagrammar based algorithm for exercise generation in the domain of context-free grammars. We also propose a probabilistic assessment algorithm based on a new identity theorem for formal series, a matrix version of the well-known identity theorem from the theory of analytic functions.

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.

Conclave: Writing Programs to Understand Programs

Authors: Nuno Ramos Carvalho, José João Almeida, Maria João Varanda Pereira, and Pedro Rangel Henriques

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


Abstract
Software maintainers are often challenged with source code changes to improve software systems, or eliminate defects, in unfamiliar programs. To undertake these tasks a sufficient understanding of the system, or at least a small part of it, is required. One of the most time consuming tasks of this process is locating which parts of the code are responsible for some key functionality or feature. This paper introduces Conclave, an environment for software analysis, that enhances program comprehension activities. Programmers use natural languages to describe and discuss the problem domain, programming languages to write source code, and markup languages to have programs talking with other programs, and so this system has to cope with this heterogeneity of dialects, and provide tools in all these areas to effectively contribute to the understanding process. The source code, the problem domain, and the side effects of running the program are represented in the system using ontologies. A combination of tools (specialized in different kinds of languages) create mappings between the different domains. Conclave provides facilities for feature location, code search, and views of the software that ease the process of understanding the code, devising changes. The underlying feature location technique explores natural language terms used in programs (e.g. function and variable names); using textual analysis and a collection of Natural Language Processing techniques, computes synonymous sets of terms. These sets are used to score relatedness between program elements, and search queries or problem domain concepts, producing sorted ranks of program elements that address the search criteria, or concepts respectively.

A Workflow Description Language to Orchestrate Multi-Lingual Resources

Authors: Rui Brito and José João Almeida

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


Abstract
Texts aligned alongside their translation, or Parallel Corpora, are a very widely used resource in Computational Linguistics. Processing these resources, however, is a very intensive, time consuming task, which makes it a suitable case study for High Performance Computing (HPC). HPC underwent several recent changes, with the evolution of Heterogeneous Platforms, where multiple devices with different architectures are able to share workload to increase performance. Several frameworks/toolkits have been under development, in various fields, to aid the programmer in extracting more performance from these platforms. Either by dynamically scheduling the workload across the available resources or by exploring the opportunities for parallelism. However, there is no toolkit targeted at Computational Linguistics, more specifically, Parallel Corpora processing. Parallel Corpora processing can be a very time consuming task, and the field could definitely use a toolkit which aids the programmer in achieving not only better performance, but also a convenient and expressive way of specifying tasks and their dependencies.

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.

MLT-prealigner: a Tool for Multilingual Text Alignment

Authors: Pedro Carvalho and José João Almeida

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


Abstract
Parallel text alignment is a key procedure in the automated translation area. A large number of aligners have been presented along the years, but these require that the target resources have been pre-prepared for alignment (either manually or automatically). It is rather normal to encounter mixed language documents, that is, documents where the same information is written in many languages (Ex: manuals of electronic devices, touristic information, PhD thesis with dual language abstracts, etc). In this article we present MLT-prealigner: a tool aimed at helping those that need to process mixed texts in order to feed alignment tools and other related language systems.

ABC with a UNIX Flavor

Authors: Bruno M. Azevedo and José João Almeida

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


Abstract
abc is a simple, yet powerful, textual musical notation. This paper presents abc::dt, a rule-based domain-specific language (Perl embedded), designed to simplify the creation of abc processing tools. Inspired by the Unix philosophy, those tools intend to be simple and compositional in a Unix filters' way. From abc::dt's rules we obtain an abc processing tool whose main algorithm follows a traditional compiler architecture, thus consisting of three stages: 1) abc parser (based on abcmtops' parser), 2) abc semantic transformation (associated with abc attributes), 3) output generation (either a user defined or system provided abc generator).

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.

Predicting Market Direction from Direct Speech by Business Leaders

Authors: Brett M. Drury and José João Almeida

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


Abstract
Direct quotations from business leaders can communicate to the wider public the latent state of their organization as well as the beliefs of the organization's leaders. Candid quotes from business leaders can have dramatic effects upon the share price of their organization. For example, Gerald Ratner in 1991 stated that his company's products were crap and consequently his company (Ratners) lost in excess of 500 million pounds in market value. Information in quotes from business leaders can be used to make an estimation of the organization's immediate future financial prospects and therefore can form part of a trading strategy. This paper describes a contextual classification strategy to label direct quotes from business leaders contained in news stories. The quotes are labelled as either: 1. positive, 2. negative or 3. neutral. A trading strategy aggregates the quote classifications to issue a buy, sell or hold instruction. The quote based trading strategy is evaluated against trading strategies which are based upon whole news story classification on the NASDAQ market index. The evaluation shows a clear advantage for the quote classification strategy over the competing strategies.

Probabilistic SynSet Based Concept Location

Authors: Nuno Ramos Carvalho, José João Almeida, Maria João Varanda Pereira, and Pedro Rangel Henriques

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


Abstract
Concept location is a common task in program comprehension techniques, essential in many approaches used for software care and software evolution. An important goal of this process is to discover a mapping between source code and human oriented concepts. Although programs are written in a strict and formal language, natural language terms and sentences like identifiers (variables or functions names), constant strings or comments, can still be found embedded in programs. Using terminology concepts and natural language processing techniques these terms can be exploited to discover clues about which real world concepts source code is addressing. This work extends symbol tables build by compilers with ontology driven constructs, extends synonym sets defined by linguistics, with automatically created Probabilistic SynSets from software domain parallel corpora. And using a relational algebra, creates semantic bridges between program elements and human oriented concepts, to enhance concept location tasks.
