The Design and Development of a Semantic File System Ontology

Semantic File System (SFS) is the vision for the future of file systems where information is given with explicit meaning to be processed by machines automatically and consumed by the users easily. SFSs extend traditional file systems to organize and retrieve information according to their semantics, intent and relationships with other resources rather than their physical locations. Ontology-based file system is a step to dissolve the borders between semantic web and semantic desktop to make the desktop part of a single giant web. Unfortunately, to the best of the authors’ current knowledge, so far, no effort has been exercised to develop an ontology for SFSs. This work contributes a SFS ontology, which extends NEPOMUK information element ontology framework into the domain of SFSs. The proposed SFS ontology is freely available with full technical definitions of terms and complete class hierarchy to be used for any purpose in information technology (IT). In addition, as a proof-of-concept implementation, we deploy the proposed ontology in the 360ᵒ SFS. Finally, to get most of the benefits of the ontology, this paper also presents a semantics-aware file manager.

Information in the Situation

Although in an ideal form the information in the world would not involve people, in reality, it has no meaning without people observing and interacting with it. There is a widespread myth (a positivistic view) that information is something in the world that does not depend on people’s point of view and that it is independent of the situation in which it occurs. But information never has fixed significance. The available data is simply the raw material that must be processed. Any particular information element gains significance only from its relationship to other information in the context in which it occurs (Woods, Patterson, & Roth, 2002). However, this chapter tries to minimize those interaction and interpretation aspects, deferring those for the later parts of the book. Instead, it concentrates on the issues of the information in the situation before it gets mentally processed.

Design of Parsing Framework with SWF File

This paper analysis the file structure of SWF. Design the parsing framework of SWF file and introduce the whole process. The parsing process is in two important steps: file head parsing and tag parsing. Analysis the format of header and Tag. Describes the structure of short tag and long tag. On the basis of the parsing procedures, a visual basic procedure is designed to achieve SWF environmental information, element information and control of information. Clarify the internal structure of the SWF file, which is important for parsing SWF.
