The corpus presented here is a collection of several tutorials and scientific papers in the field of Information Technology with 603 annotated definitions from Portuguese. The texts were collected from the Web at the beginning of the 2006 and they are organised in 32 files of three different sub-domains with 268,064 tokens: Information Society (91,825 tokens), Information Technology (80,483 tokens), and e-Learning (94,756 tokens).

Segmentation level: Word

Format: text/xml

Annotation Mode: Manual (The corpus was automatically annotated with morpho-syntactic information using the LX-Suite (available at: http://lxcenter/services/en/LXServicesSuite.html). In a second step, in each sentence with a definition structure, the term defined, the definition, and the connector were manually annotated using a different XML tag, markedTerm, connector, and markedTerm, respectively, with the assignment of the information about the type of definition. The definition typology is made of four different classes whose members were tagged with is_def, for copula definitions, verb_def, for verbal non copula definitions, punct_def, for definitions whose connector is a punctuation mark, and finally other_def, for all the remaining definitions.)
