This paper describes an approach to assessing semantic annotation activities based on formal concept analysis (FCA). In this approach, annotators use taxonomical ontologies created by domain experts to annotate digital resources. Then, using FCA, domain experts are provided with concept lattices that graphically display how their ontologies were used during the semantic annotation process. In consequence,...
This paper describes an approach to the modular specification of XML processing tasks. The approach is language-oriented: it considers the programs that process a type of XML documents to be processors (e.g., compilers or interpreters) for the markup language used in these documents. In addition, it encourages the declarative specification of these processors through attribute grammars. In doing so,...
Building on our previous work on the combination of JavaCC and SAX, we developed a new syntax-directed processing environment for XML documents. In this new environment, we use CUP as the parser-generation tool and StAX as the interface with the underlying XML parsing framework. The new environment supports a richer set of processing-specific context-free grammars (i.e., the grammars used for representing...
This paper proposes a generative approach to the construction of XML processing components. This approach promotes the high-level description of XML processing tasks with attribute grammars (a high-level formalism used in the definition of computer languages). The components themselves are produced by automatically processing these high-level specifications with a suitable generator. The approach...
The services provided by learning object repositories are usually enabled by the processing of the metadata documents associated with these learning objects. This paper proposes a way to process these metadata documents, which are usually encoded in XML, through a framework called XLOP. XLOP is based on attribute grammars, a well-known technique used in the development of language processors. XLOP...
This paper presents XLOP (XML language-oriented processing), an environment that permits the description of XML processing applications with attribute grammars (formalism used to describe the semantics of computer languages). The environment also includes a generator able to translate attribute grammar-based specifications into the specification language of CUP, a well-known YACC-like environment...
In this paper we show how to integrate JavaCC, a popular translator-generation tool, with any standard XML parsing environment supporting the SAX specification. This integration lets developers build efficient XML processing applications which act as left-to-right, one-pass translators. The integration also facilitates the maintenance of these applications, since they are specified as syntax-directed...
