What is the semantic gap problem?
The “semantic gap” is a well-know problem in multimedia. The challenge is to accurately classify and effectively search multimedia content from automatically extracted low-level audio-visual features.
What is semantic gap in image retrieval?
Thus, semantic gap refers to the limitations of low-level image features in describing human semantics. This learning is done after low- level feature extraction. Therefore, semantic image retrieval depends on both low-level features and high-level keywords of the images.
Who will reduce execution gap?
Preprocessor and language migrator works same, but preprocessor minimizes Execution gap and Language Migrator minimizes specification gap. An interpreter is a language processor which bridges an execution gap without generating a machine language program.
What is machine language?
Sometimes referred to as machine code or object code, machine language is a collection of binary digits or bits that the computer reads and interprets. A computer cannot directly understand the programming languages used to create computer programs, so the program code must be compiled.
What is execution gap in system programming?
Execution gap: It is the gap between the semantics of programs written in different programming languages. The execution gap is bridged by the translator or interpreter. Advantages of introducing the PL domain: (a) Large development times are reduced. ( b) Better quality of software. (
What do you understand by language processor?
language processor: A program that performs tasks, such as translating and interpreting, required for processing a specified programming language. Note: Examples of language processors include a Fortran processor and a COBOL processor.
What is PL domain in system programming?
The use of a PL introduces a new domain called the programming language domain (or PL domain). Execution gap Specification gap Application Domain PL Domain (problems, ideas, methods, to solve these problems) Execution Domain (machine code, devices, etc.)
What is the semantic gap between two specifications of the same task?
Specification Gap : It is the semantic gap between the two specifications of the same task. Execution Gap : The gap between the semantics of programs written in the different programming languages. Language Processors : It is a software which bridges a specification or execution gap.
What is’semantic gap’in image retrieval?
Semantic gap is a term that is popularly misunderstood and misused by people who do not know much about linguistics and semiotics. Semantic gap is not a vertical issue. It is not about abstraction capability. It has nothing to do with the distance between two sign systems in terms of abstraction capability.
Is there a semantic gap between language and machine?
There is no semantic gap between them since a program is transferred from the high level language to the machine code by a program, e.g. a compiler which itself runs on a Turing machine without any user interaction. The semantic gap actually opens between the selection of the rules and the representation of the task.
Is the semantic gap ever to be fully closed?
The general expression of limitations for rule based deduction by Gödel’s incompleteness theorem indicates that the semantic gap is never to be fully closed. These are general statements, considering the generalized limits of computation on the highest level of abstraction where the semantic gap manifests itself.
How does OODBMSs help reduce the semantic gap?
OODBMSs (object-oriented database management system) advocates sometimes claim that these databases help to reduce the semantic gap between the application domain ( miniworld) and the traditional RDBMS systems.
