The dissertation focus on information and knowledge representation, investigate the match and differential points between documentary languages, available in Information Science and markup languages, developed and used in Computer Science, with the objective of identify actions, theories and necessary processes for a bigger integration between the two areas. For this, it is established a revision of the necessary basic elements to the representation of the information and knowledge in the scope of the Information Science. To become possible the comparison between areas, consecrated knowledge and information representation models available in Information Science are presented, such as metadates, thesaurus and ontologies. In the scope of the Internet, the techniques of representation with the use of markup languages more used are presented and its contributions for the development of the Web Semantics. It is locked in presenting a proposal of structure of representation for information resources, especially developed for the Internet. The proposal was developed from the existing resources in the Computer Science, particularly, its available in language XML. It contemplates the definition of a ontology and culminates with the creation of a structure in XML to store metadates of electronic articles. / A Ci?ncia da Informa??o vem estudando formas de representa??o da informa??o e do conhecimento visando a recupera??o da informa??o. Esta pesquisa tem seu foco na representa??o do conhecimento e da informa??o, procurando investigar quais s?o os pontos convergentes e divergentes entre as linguagens document?rias da Ci?ncia da Informa??o e as linguagens de marca??o desenvolvidas e utilizadas na Ci?ncia da Computa??o, tendo em vista identificar as a??es, teorias e processos necess?rios para uma maior integra??o entre as duas ?reas. Para isso, faz-se uma revis?o dos elementos fundamentais necess?rios a represental??o da informa??o e do conhecimento no ?mbito da Ci?ncia da Informa??o. Para tornar poss?vel a compara??o entre ?reas, apresentam-se os modelos mais consagrados de representa??o do conhecimento e da informa??o provenientes da Ci?ncia da Informa??o, tais como metadados, tesauros e ontologias. No ?mbito da Internet, apresentam-se as t?cnicas de representa??o com o uso das linguagens de marca??o mais utilizadas e suas contribui??es para o desenvolvimento da Web Sem?ntica. Encerra-se apresentando uma proposta de estrutura de representa??o para recursos informacionais, especialmente os disponibilizados pela Internet. A proposta foi desenvolvida a partir dos recursos existentes na Ci?ncia da Computa??o, particularmente, os oferecidos pela linguagem XML. Contempla a defini??o de uma ontologia e culmina com a cria??o de uma estrutura em XML para armazenar metadados de artigos eletr?nicos.
