Text document clustering techniques automatically become an important research in which volume of text document via digital media is growing rapidly. This technique is known as document clustering. Document clustering is a method of grouping documents based on their similarity. For groupping these documents, one of the clustering algorithms is used, namely Active Fuzzy Constrained Clustering (AFCC), which combines fuzzy and semi-supervised clustering methods where text documents as a bag of words will be calculated with the value of meaningful words using the Vector Space Model. (VSM). The AFCC algorithm is identified by the use of pairwise constraint and centroid in its cluster. The input documents tested in the research are a collection of documents in the BBC News Archives. Based on the research that has been done, using the parameters of the maximum number of clusters, the maximum number of constraints per iteration and the maximum number of iterations, the AFCC algorithm results in grouping text documents that are news article. Performance measurement of clustering results in this research uses the Confusion Matrix approach, which can be generated with an average precision and recall value of 0.53, and an accuracy value of 0.52
<p>The development of internet in recent years caused a major prospect in online business. One of the businesses is e-commerce. E-commerce is an activity of selling and buying information through computer network. Website is a medium that can be used in e-commerce implementation. E-commerce website becomes an important part in supporting the companys success. Yet, there are many e-commerce websites that are not understandable by the user since the user cannot find out what they want. In addition, e-commerce website is still difficult to use. The users who cannot find what they want in e-commerce website will surely decrease the usability of the website. As a result, there must be a design planning which can be comprehended by the users to find the expected product easily. The Collaborative Analysis of Requirement and Design method can be used to solve the design problem. The method is one of the techniques in user centered design. The method focuses on users because in its process it involves the users, and the users are the the information source of this method. The information that is gained from the users can be taken form interview, questionairre and experimentation with component order. The result of this research gives contribution to the websites, that is advise to improve the website design so that the users can understand the working system and the design more comprehensively.</p>
