Abstract	Master’s Dissertation Post-Graduate Program in Computer Science Federal University of Santa Maria A PROCESS FOR CONCEPTUAL SCHEMA EXTRACTION IN DATASETS JSON BASED ON TEXT SIMILARITY TECHNIQUES AUTHOR: FHABIANA THIELI DOS SANTOS MACHADO ADVISOR: DEISE DE BRUM SACCOL Defense Place and Date: Santa Maria, June 29, 2017. NoSQL (Not Only SQL) data models have been notable for their promise of schema flexibility and scalability considering the large volume of data. Their flexibility allows, for example, that documents within the same collection have different attributes. This fact becomes a problem when there is the need to access the database in a unified way, or in an automated way through programming, since there is no standard structure. In this sense, this work presents a process for schema extraction in datasets in JSON (JavaScript Object Notation) data sources. This proposal differs by analyzing attributes that represent the same information, but are differently written. In the context of this work, writing difference concerns the treatment of synonyms, similar spelling and identical word radical. To achieve this goal, we use techniques such as character based similarity functions and synonyms, as well as stemming extractor. Therefore, this work aims to extract the implicit schema in these datasets by applying different textual equivalence techniques in attribute names, as well as to produce a conceptual schema and the respective mappings for the equivalent terms.
