Abstract: A method for document similarity analysis. The method includes obtaining a document to be archived, and identifying a document category similar to the document to be archived. The similar document category is identified by: identifying a document category that includes indexing terms that are identical to indexing terms in the document to be archived, obtaining term frequency vectors for the identical indexing terms in the document to be archived and in the identified document category, generating normalized term frequency vectors, from the term frequency vectors, calculating a common denominator similarity based on the normalized term frequency vectors and a common denominator, and determining that the document category is similar to the document to be archived based on the common denominator similarity. The method further includes registering the document to be archived in the document category.

Abstract: Methods for forming a diamond like carbon layer with desired film density, mechanical strength and optical film properties are provided. In one embodiment, a method of forming a diamond like carbon layer includes generating an electron beam plasma above a surface of a substrate disposed in a processing chamber, and forming a diamond like carbon layer on the surface of the substrate. The diamond like carbon layer is formed by an electron beam plasma process, wherein the diamond like carbon layer serves as a hardmask layer in an etching process in semiconductor applications. The diamond like carbon layer may be formed by bombarding a carbon containing electrode disposed in a processing chamber to generate a secondary electron beam in a gas mixture containing carbon to a surface of a substrate disposed in the processing chamber, and forming a diamond like carbon layer on the surface of the substrate from elements of the gas mixture.

Abstract: A method for tokenizing documents.
