The selection of a classifier is only one aspect of the problem of data classification. Equally important (if not, more so) is the pre–processing strategy to be employed. In this paper, a pre–processing step is proposed in order to increase accuracy of classification. The objective of this pre–processing step is to achieve a high degree of separation among classes before the classifier is trained or tested. This results into a trace ratio problem which is difficult to solve. Methods such as Linear Discriminant Analysis (LDA) have already been used for the solution of this problem by turning it into a simpler yet inexact problem. In our approach ACO is used to solve the trace ratio problem directly also can increase classification accuracy by finding a transformation matrix to discriminate between classes.<\div>

Along with the theoretical developments in new linguistics, the computer analysis methodology for analyzing text and grammar are developed. The grammar of any language in here is referred to as a series of understandable grammatical orders for computer by help of which one can accurately analyze the syntactic components of any given sentence. A typical sentence is analyzed and disintegrated to its components (noun phrases, verb phrases, adverbial phrases etc.) by the help of parser tools that play a vital role in designing and accuracy of any other text–analyzing tool in computer. Taking into account the lexical morphology, position, ordering of words in a sentence as well as the prior and posterior lexical items, the present parser tool designs the syntactic tree or parsing. In fact, the parsing process is completed by considering the lexical morphology (the study of the form of the words) and the syntax of the Persian language. Therefore, as much as the writing and documentation of a sentence is polished and punctuation is accurate, the parsing process is more accurate and more successful. In addition, the tagging process for different components of the sentence would be easier<\div>
