Obteniendo resultados del análisis de textos

Oskar Casquero has sent you a clip...

Oskar Casquero's Message:
Éste es un ejemplo que utiliza conjuntamente las herramientas "Text Content Analysis Tool" y "Tagline Generator" para analizar y comparar las keynotes de Steve Jobs, Bill Gates y Michael Dell.

Apple CEO Steve Jobs and Microsoft Chairman Bill Gates both gave big keynote addresses last week. So how did their messages compare? At the suggestion of a reader, we ran the text of both speeches through the tag-cloud generator, a program that displays the most commonly used words in varying sizes, depending on how often they're spoken. For further comparison, we did the same thing with Dell Chairman Michael Dell's Consumer Electronics Show keynote.

And just for fun, we also analyzed the text with the language-assessment tools at UsingEnglish.com. Click on the names of those ratios below for definitions. Lower scores generally mean that the language is easier to understand. By those measures, one executive did noticeably better than the others.

Read on to see what we found:

Notes: Gates' tag cloud differs from the earlier version because comments by Robbie Bach and other Microsoft representatives were omitted from this analysis, for purposes of direct comparison among Jobs, Gates and Dell. Likewise, the analysis did not include comments from people on stage other than Jobs or Dell.

For an alternative view, see a version of this that uses a slider control.

Tagline Generator: timeline-based Tag Clouds

Oskar Casquero has sent you a clip...

clipped from chir.ag
Tagline Generator by Chirag Mehta is a simple PHP codebase that lets you generate chronological tag clouds from simple text data sources without manually tagging the data entries.

Once you have populated the data source and configured the generator, it makes a list of all the unique words that have been used and counts how many times each word is used. Next it identifies the different variations of words and combines them under the most common variation using the Porter Stemming Algorithm. E.g. "promised", "promises", "promising", and "promise" might be grouped under "promises".

Then it removes the most common words like "the", "and", "this", "that" and some not so common language-specific words like "hitherto", and "notwithstanding". Once the commonly used language-specific words are removed, it makes a "tag cloud" in which the more commonly used words are shown in bigger font size than the less frequently used ones. Additionally, it tries to figure out how long ago a given word hit its peak usage and brightens the recently used words while fading away words haven't been used in a while.

    Como extraer el audio (mp3) de un video (flv)

    Oskar Casquero has sent you a clip...

     clipped from www.opcionweb.com

    Existen infinidad de programas que realizan esta función desde el ordenador, teniendo que descargar el vídeo (FLV) del sitio web y después procesarlo para extraer la pista de audio (MP3).


    Pero me ha llamado la atención estos dos servicios web, que on line realizan fácilmente esta tarea, permitiendo extraer el audio, subiendo un fichero de vídeo flv (formato flash vídeo usado por la mayor parte de los portales de video de internet) o indicando la url del vídeo.


    vidtomp3

    VidtoMP3 es un servicio web que solo permite extraer desde una url, reconociendo los sitios de vídeo más populares: YouTube, MegaVideo, Dailymotion, Metacafe, Veoh, Myspace, Break, iFilm, Google Video, Bolt, ClipJunkie, ClipShack, CollegeHumor, FunnyJunk, Glumbert, GoFish, Grouper, Hallpass, MilkandCookies, Putfile, SantaBanta, Sharkle, Shoutfile, Vimeo, vSocial, Yikers, ZippyVideos…


    Sin necesidad de registro, gratis y de la forma mas sencilla, solo hay que introducir la url limpia del vídeo (la que ofrece como enlace el portal del vídeo), a veces la de la barra de dirección incluye parámetros que puede hacer que no funcione el reconocimiento de ubicación para la extracción.


    Tras esperar unos segundos, minutos si el servidor esta muy colapsado, ya esta disponible el mp3 para escucharlo, descargarlo o compartirlo.

    Google Sites sustituye a Google Pages

    Google SitesDespués de casi año y medio desde que Google comprara Jostpot, por fín lo saca a la luz como Google Sites, una herramienta colaborativa, que podremos encontrar en Google Apps, y que nos permite la creación de sitios web como si estuviésemos editando un documento.

    Para ello deberemos de tener nuestra Google Apps y desde ella acceder a Google Sites, desde el cual nos guía en el proceso de la creación de nuestro espacio. Indicaremos el nombre de nuestro sitio, categoría, descripción, elección de colaboración con todos o con algunos miembros elegidos de la organización, posibilidad de ser accesible públicamente y la elección de uno de los 20 temas disponibles:

    Omeka

    Una herramienta para la publicación fácil y organizada de pags web. En http://hurricanearchive.org/ podéis ver un ejemplo de sitio construido con esta herramienta
    clipped from www.dancohen.org

    Omeka logoToday the Center for History and New Media launches another major software platform that we hope will be of great help to universities, libraries, museums, historians, researchers, and anyone else who would like to put a collection or exhibit online. It’s called Omeka, from the Swahili word meaning “to display or layout goods or wares; to speak out; to spread out; to unpack.” The public beta released today was underwritten by the generosity of the Alfred P. Sloan Foundation and the Institute of Museum and Library Services.

    I’ll get to the details momentarily, but I’ve found that it’s often helpful to brashly distill years of careful thought, design, and programming into a handy catchphrase that anyone can understand and pass around. For Zotero, it’s “like iTunes for your references and research”; for Omeka, think “WordPress for your exhibits and collections.”
