ABSTRACT:
Apparatus and methods are described for network content in dictionary-based (de)compression. Content for compression is parsed into discrete constructions, such as phrases, words, etc. The discrete constructions are passed to a searching engine to locate network information at one or more network locator identities, such as URI's (URL's, URNs) that correspond to the discrete constructions. Upon locating the network information, a dictionary of entries corresponding to the content is created. The content is encoded from the dictionary by indicating raw or relative offsets into the network information per each of the network locator identities. Decoding occurs anti-symmetrically to the encoding. In this manner, the vastness of network content, e.g., the world wide web, is leveraged to provide relevant dictionaries for de-/encoding. Searching for candidate dictionaries, scoring same and safeguarding against volatile dictionary content are other noteworthy features. Computer program products and computing network interaction are also defined.
