Multimedia and XML Searching



XML retrieval incorporates “structured text retrieval” models, which utilized document structure and content.  The architecture of a document correlates to a pre-conceived structure, i.e. “a section, a chapter, a title” as explained by Baeza-Yates. 

XML single hierarchical structure is reflected to the user in associated links, in addition to behind the scene structural makeup.  The standard language of the Web is XML, and this provides consistency within the multitudes of websites and webpages available to the public, reflecting commonality of relationships.  Baeza-Yates expounds stating, “Using the context [which refers to terminology positioned within the text of the document] of an element to estimate its relevance is nothing else than capturing relationships between elements in XML relationships, in particular for long documents, consistently improves retrieval performance” (Baeza-Yates, p558). 

Popular XML Query Languages are:
a)     XPATH
b)     NEXI
c)      XQuery
d)     XQuery Full-Text

  Although, different XML languages are being used for effective searching, the user interface is most important in the efficiency of the program.  The user-friendly interface allows users to search effectively (they find what they are looking for) and efficiently (in the least amount of time).

The vast number of multimedia devices (computers – desktops, laptops, tablets; smartphones; TVs; cameras; gaming consoles; etc.) and formatted data platforms are catalysts for instantaneous communication in our everyday lives.  “Multimedia is visual and sound data, pictures, graphs, images, videos, animations, speech, music, sounds, and even 3D visualizations . . . Includes complex spatial and temporal relations, derived from the life cycle of digital media – capturing, editing, compressing, processing” (Baeza-Yates, p587).  Pandora’s Box has been opened and the choices are ever-expanding. 

We regularly used various websites to retrieve multimedia information.  For instance, my blog utilizes Flickr to retrieve the chocolate related photos, BBC website for audio podcasts, and other websites for data retrieval.  The billions of data available for retrieval on the web are mind-boggling.
