Multiple Corpógrafos installed in several university departaments and countries: the “Corpógrafo Community” Centralized database to collect terminology / conceptual maps from the Corpógrafo Community Large-Scale Terminology/ Knowledge Resources for Specialized Search Engines, Technical Writing, Translation, etc The future… Motivation Build an environment that helps users in the entire process of corpora research. The tool should not require advanced computer skills and should be easy to use by all types of users, from students to researchers. Functionalities required: Web access: use anywhere, anytime from any computer. No software installations. Collect texts: text extraction from structured files, downloading texts from the Web Text pre-processing: “cleaning” text, segmentation, text annotation, text encoding searchable or exchangeable format; Corpus search: regular expression concordances, collocation extraction, frequency based statistics (N-grams count); Information extraction: terminology, semantic relations, conceptual maps Knowledge-resource building: specific-domain glossaries, thesauri, terminological databases and ontologies; categorized word-lists; Comparable corpora studies: compilation and search over comparable corpora Exporting results to other formats and applications: to standard terminological databases, translation memories, etc. Terminology Extraction General Corpora Studies Collect Texts Text Extraction Corpora (several languages) Web DOC TXT PS PDF HTML create and manage multilingual Terminology DB’s Improving processing and research of the Portuguese language Fostering collaboration among researchers Providing public and free-of-charge tools to the community Linguateca – Our mission!
