A complex system is generally regarded as being a network of elements in mutual interactions, which total behavior cannot be deduced from that of its parts and their properties. Thus, the study of a complex phenomenon requires a holistic approach considering the system in its totality. The aim of our approach is the design of a unifying theoretical framework to define complex systems according ...

Due to the tremendous use of computers, need for dealing with digital information continues grow. This has led constructing a structure saving in way that eases data retrieval and processing. An system is table form contains all needed user reach decision. Information systems are most common used knowledge representation, attribute reduction plays an important role paper devoted proposing strat...

PretopoLib is a library of data types and algorithms based on pretopology theory. Its interest is its data structures representing mathematical sets and all the operations related to them. The main features of the library are a clear separation of computation and visualization, efficient sets data types, and its ease of use to build model or application prototypes in the complex systems simulat...

We present in this paper an automatic system of handwritten isolated Arabic characters recognition. It is based on a pretopological approach. The approach is based on a criterion constructed from a pretopological pseudo-distance that allows to measure the degree of dissimilarity between the characters. On a database of 6188 handwritten isolated Arabic characters, the experimental results show t...

Latent semantic analysis is a computation method to demonstrate a major component of language learning and use. Thus, in this sense, it is a theory of meaning, such that it applies to and offers an explanation of phenomena of meaning in words and passages of words. This enables LSA to hold a strong position in the automated document classification, document analysis, etc. Though the experiments...
