Language Specification and Processing Group

Members

Group Description

Although all the technological advances related to multimedia, in a computer system most relevant digital data still circulates in textual format: computer programs, specifications, documents and other information resources have their content in this format. In order to be read and interpreted by a machine, texts should be valid sentences of a known language to be possible to associate them some meaning. The path towards this meaning takes us to syntax and then to semantics.

The "Language Processing" area is concerned with approaches, methods and tools for the "specification of languages" and the "systematic development of their processors".

Language syntax and semantics is formally defined by a Grammar; in this area we support our work on regular grammars (or regular expressions), context free grammars, translation or attribute grammars, affix grammars, stochastic-dependency or transition-network grammars, graph grammars, annotation schemas, etc.

Language Processors are systematic and automatically built using tools, called Generators, that read a grammar and produce the analysers/translators.

Although we keep the same approach, different kind of texts require specialized methods and tools. So the area is split into three main research directions:

  • 1) completely structured texts, that belong to "formal languages" (FLP);
  • 2) semi-structured texts, that belong to "annotation languages" (ALP);
  • 3) unstructured texts, that belong to "natural languages" (NLP).

Inside the "LP@di/cctc.uminho.pt" group:

1) Pedro Rangel Henriques, Maria João Varanda Pereira, Daniela da Cruz, Nuno Oliveira, Alda Gançarski, and Mario Berón work on the first direction (formal language processing -- FLP).

At moment the research topics are:

  • textual and visual languages;
  • program analysis and transformation;
  • program visualization/animation;
  • program comprehension.

2) José Carlos Ramalho work on the second direction (semi-structured document processing).

At moment the research topics are:

  • document markup and XML standards;
  • archiving and digital libraries;
  • semantic web and virtual museums;
  • web-services and location aware services.

3) José João Dias de Almeida, Alberto Simões and Nuno Carvalho work on the third direction (natural language processing).

At moment the research topics are:

  • Text classification and Automatic summarization;
  • Discourse analysis and Part-of-speech tagging;
  • Machine Translation;
  • Information extraction (IE) (including named entity recognition and relationship extraction);
  • Information retrieval (IR) and text mining.

Notice that "definition and support of Domain Specific Languages" and "ontology processing" are transversal research trends on which all the subgroups are working. In a similar way, it is clear that "ETL process" (extract-transform-load) is a target, an application area, common to all the subgroups.

The Master course on Language Engineering, UCE30-EL (Engenharia de Linguagens), offered by the "LP@di/ctcc.uminho.pt" group composed of the four modules below, directly reflects this status-quo and this organization: Grammar Engineering; Software Analysis and Transformation; Document Processing; Natural Language Processing.

Also the events and journals that the group members are co-founders and organizers corroborate the three research trends described:

  • SLaTE, International Symposium on Languages, Applications and Technology, that integrates the previous events:
    • XATA, XML -- Aplicações e Tecnologias Associadas;
    • CoRTA, Compilers, programming languages, Related Technologies and Applications;

  • Linguamática, Revista para o Processamento Automático das Línguas Ibéricas (ISSN: 1647-0818)
