Techniques for comparing a first document to one or more second documents are provided. At least one weight is assigned to one or more elements in the first document. A weighted document is generated in accordance with the at least one assigned weight. One or more comparison scores are computed by comparing each of the one or more elements in the first document to each of one or more elements in a given second document in accordance with one or more comparison rules. The one or more comparison rules determine if a given element in the first document and a given element in the given second document are compared using one or more language hierarchies and/or one or more similarity ranges. A similarity score is generated in accordance with the generated weighted document and the one or more computed comparison scores. The one or more second documents are retrieved in accordance with the generated similarity score.
