The aim of this paper is to take readers through the basic steps involved in building a corpus of language data for different purposes. This is done via gathering information about corpus construction from related sources. After a review of literature (regarding corpus construction and the use of corpus in different fields) , this article offers advice in a non-technical style to help the researchers to make sure that their corpus is well-designed and fit for the intended purpose. Key points to be considered in constructing any corpus (written or spoken language) include: Sampling, Size, Representativeness, Balance, General vs. Specialized corpus and Homogeneity. The steps involved in constructing a text corpus are: text selection, text normalization and different kinds of annotation. The steps to be followed in constructing a spoken language/speech-based corpus are: data gathering, transcription, representation, annotation and access. In this paper all the afore-mentioned steps have been explained with related details.
