Applying Attribute Grammars to Teach Linguistic Rules

Authors: Patrícia Amorim Barros, Maria João Varanda Pereira, and Pedro Rangel Henriques

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

Abstract
An attribute grammar is a very well known formalism to describe computer languages but it can also be successfully used to describe linguistic phenomena. Since natural languages can also be expressed in grammars it is natural to describe rules using the same formalism. Linguistic teachers of the University Complutense of Madrid started using attribute grammars but they lack a tool that helps them to specify linguistic rules in a friendly and natural way. Therefore we propose a domain specific language (NLSdsl) carefully designed for non-programmers that will be implemented on an AnTLR based system.

Profile Detection Through Source Code Static Analysis

Authors: Daniel Ferreira Novais, Maria João Varanda Pereira, and Pedro Rangel Henriques

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

Abstract
The present article reflects the progress of an ongoing master's dissertation on language engineering. The main goal of the work here described, is to infer a programmer's profile through the analysis of his source code. After such analysis the programmer shall be placed on a scale that characterizes him on his language abilities. There are several potential applications for such profiling, namely, the evaluation of a programmer's skills and proficiency on a given language or the continuous evaluation of a student's progress on a programming course. Throughout the course of this project and as a proof of concept, a tool that allows the automatic profiling of a Java programmer is under development. This tool is also introduced in the paper and its preliminary outcomes are discussed.

Problem Domain Oriented Approach for Program Comprehension

Authors: Maria João Varanda Pereira, Mario Marcelo Beron, Daniela da Cruz, Nuno Oliveira, and Pedro Rangel Henriques

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

Abstract
This paper is concerned with an ontology driven approach for Program Comprehension that starts picking up concepts from the problem domain ontology, analyzing source code and, after locating problem concepts in the code, goes up and links them to the programming language ontology. Different location techniques are used to search for concepts embedded in comments, in the code (identifier names and execution traces), and in string-literals associated with I/O statements. The expected result is a mapping between problem domain concepts and code slices. This mapping can be visualized using graph-based approaches like, for instance, navigation facilities through a System Dependency Graph. The paper also describes a PCTool suite, Quixote, that implements the approach proposed.

Learning Spaces for Knowledge Generation

Authors: Nuno Oliveira, Maria João Varanda Pereira, Alda Lopes Gancarski, and Pedro Rangel Henriques

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

Abstract
As the Internet is becoming the main point for information access, Libraries, Museums and similar Institutions are preserving their collections as digital object repositories. In that way, the important information associated with digital objects may be delivered as Internet content over portals equipped with modern interfaces and navigation features. This enables the virtualization of real information exhibition spaces rising new learning paradigms. Geny is a project aiming at defining domain-specific languages and developing tools to generate web-based learning spaces from existent digital object repositories and associated semantic. The motto for Geny is "Generating learning spaces to generate knowledge". Our objective within this project is to use (i) ontologies - one to give semantics to the digital object repository and another to describe the information to exhibit - and (ii) special languages to define the exhibition space, to enable the automatic construction of the learning space supported by a web browser. This paper presents the proposal of the Geny project along with a review of the state of the art concerning learning spaces and their virtualization. Geny is, currently, under appreciation by Fundação para a Ciêencia e a Tecnologia (FCT), the main Portuguese scientific funding institution.

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.
