Abstract

Retrieval models and techniques can be applied to retrieve memo information and it does relate to certain queries or concepts. Different method of retrieval shows different relevant documents. Therefore, different methods are used to retrieve, structure and similarity measures being used to retrieve memo. The data are collected at Center of HND Studies at TATi University College. The process that has been applied is digitizing, stop word removal, stemming and building index. The results of this process then stored in database. In this study 50 document of memo being used, where refer to the titles and the document. In order to show the measure of different memo structure three similarity measures being used. The structure refers to the titles of memo, the documents and combination of both title and documents. The results shows that title structure have the lowest performance of result compared to document structure and the combination of both. Meanwhile, in similarity measures the results shows that weighting schemes using cosine perform well compared to Dice and Russell-Rao. The overall result shows that the best performance for retrieving memo is by using document structure coupled with Cosine similarity. (Author's abstract)
