Abstract: A text mining program is provided that allows a user to perform text mining operations, such as: information retrieval, term and document visualization, term and document clustering, term and document classification, summarization of individual documents and groups of documents, and document cross-referencing. This is accomplished by representing the text of a document collection using subspace transformations. This subspace transformation representation is performed by: constructing a term frequency matrix of the term frequencies for each of the documents, transforming the term frequencies for statistical purposes, and projecting the documents or the terms into a lower dimensional subspace. As the document collection is updated, the subspace is dynamically updated to reflect the new document collection.

Abstract: A portable cloth holder device 8 including a cloth 50 made of moisture absorbent material selectively connected to a cord attached at it proximal end to a spring-loaded reel mechanism 25 located in an outer housing 9. The outer housing 9 is selectively attached to the user or to a support surface via an adjustable clip 18. The cloth 50 can be selectively extended by pulling the distal end of the cord 30 from the outer housing 9. The cord 30 is sufficient length so that when the cloth 50 is pulled and fully extended, moisture and perspiration can then be removed by the user from his or her head, legs, and arms when the outer housing 9 is attached to the user's waist. When the user has finished drying the body, the cloth 50 retracts and automatically returns to its resting position inside the outer housing 9. The cloth 50 may be easily removed from the cord 30 for washing.
