CORPORART Semantic Word Sketch Grammar for European Portuguese – Nouns, verbs and adjectives CQL expressions for semantic relations extraction




The CORPORART_GRAMM_PT_1.0 is a Semantic Word Sketch Grammar for European Portuguese, codified using the Corpus Query Language (CQL) for Sketch Engine, but adaptable to other systems using CQL. The CORPORART_GRAMM_PT_1.0 consists of 42 lexical-syntactic patterns for extracting semantically related items, encompassing various semantic relations, such as hyponymy/hyperonymy, holonymy/meronymy, as well as relations crucial for event description (e.g., agent, result, instrument, location etc.) and adjective description (e.g., characterization).
Usually, WordSketch Grammars function for collocations extraction and categorization, according to their grammatical relations. The innovative aspect of our CQL Grammar is that it is designed for semantic information retrieval. The CQL grammar operates based on a keyword and the result is displayed in the form of a Word Sketch. Even though CORPORART_GRAMM_PT_1.0 was initially designed for CORPORART, it can be applied to any European Portuguese corpus.
