Resumen:
La mineria de texto consiste en descubrir informacion nueva y previamente desconocida mediante la extraccion automatica de informacion de textos en lenguaje natural. Un objetivo clave de la mineria de texto es el descubrimiento de entidades, eventos y relaciones entre ellos. De esta forma que se proponen hechos o hipotesis nuevos que seran explorados en profundidad mediante metodos de experimentacion mas convencionales.
Este tutorial pretende dar una breve perspectiva inicial sobre la mineria de datos aplicada a texto, desde una perspectiva de Procesamiento del Lenguaje Natural. Presentaremos algunas tecnicas y metodos basicos de analisis linguistico automatico, asi como las tecnicas de descubrimiento de conocimiento aplicadas a problemas textuales. Discutiremos algunos trabajos de investigacion a modo de ilustracion de las tecnicas y metodos presentados.
Se brindaran breves ejercicios practicos con el fin de familiarizar a la audiencia con el objeto de estudio y los metodos de trabajo.

Abstract:
Digital media are becoming increasingly more common as a repository and representation of intellectual property, especially audio, images, and video. With this ubiquity come requirements for security (who may gain access the content?) and integrity (is the information unadulterated/original?).
This presentation focuses on techniques for achieving security and integrity of digital content. We differentiate between one-step (a protected single-step transmission between origin and destination) and multi-step (the content passes through several hands in a protected way) methods. Also, we classify content as either text-based (text, programs) or signal-based (audio, video) and explain the salient characteristics. Within the context of these types of goals and objectives, we review various approaches towards achieving security or integrity.
Cryptography-based approaches are the traditional means of achieving these objectives. However, they have serious problems with signal-based content, most notably processing requirements, sensitivity to errors, or increases in the amount of data to be stored or transmitted. Also, they are only single-step.
Digital watermarks have recently attracted attention as an alternative approach to protecting digital content. While they do not achieve security nor are they directly applicable to text-based content, they can be used to realize multi-step integrity of signal-based content.

Abstract:
The tutorial focuses on metrics that are especially useful for software engineering projects. These include measures of defect levels, productivity, and quality. Examples illustrate how to get maximum information out of a small set of key metrics. The session concludes with a discussion of aligning metrics within an organization and with a review of metrics recommended for use at level two of the SEI CMM.
Brief CV:
Dennis Frailey is a Principal Fellow at Raytheon Company in Plano, Texas and an Adjunct Professor of Computer Science at Southern Methodist University (SMU).
At Raytheon, Dennis is a pillar of the software engineering community. In addition to his program duties (he's currently responsible for software planning, processes and procedures for a major U.S. Army program) Dennis is a contributor to several business-wide and corporate-wide efforts for software engineering improvement, including software measurement, software quality and software development cycle time reduction. He also teaches internal courses in many aspects of software engineering and program management. Prior assignments include computer architect, operating system designer, compiler designer, and speechwriter for company executives.
Dennis has also worked at Texas Instruments, the Ford Motor Company, and as a tenured, Associate Professor at SMU. Although he left SMU in 1977, he has continued as an adjunct professor ever since. Dennis helped start the software engineering program at SMU and was vice-chair of the ACM/IEEE Software Engineering Coordinating Committee, chartered to foster the development of software engineering as a professional computing discipline. He continues this work as a member of the IEEE-Computer Society Professional Practices Board. Dennis is also an ABET accreditation program evaluator in the fields of computer science, computer engineering and software engineering and was previously vice president of the ACM. He holds an MS and PhD in computer science (Purdue) and a BS in mathematics (Notre Dame).

Duracion: 4:30 horas.
Motivation:
Internet has become one of the most important communication channels. The number of nodes and people connected to internet is counted by millions. In many cases, this is the vehicle through which, isolated communities can interact with the rest of the world in an every day more globalised world. The opportunities the web has brought are very important but to be able to profit from them it is necessary a basic knowledge of the technology.
Objectives:
This tutorial introduces the basic concepts related to the Multimedia Services present in the web. The main standards for audio, images and video are presented as well as the principal protocols to achieve the expected QoS for the synchronization and resource management.
