Usability of websites has been studied severally in a general term in different sectors such as entertainment, social media and e-commerce. Higher education is a sector that needs more attention because Universities are very important in the society and their websites hold important information for prospective students, parents, faculty, students of the university and the public. Several literature reviews have been conducted on website usability evaluation, not many have focused on University website usability evaluation. Existing reviews of University website usability evaluation have based their review on certain aspect of usability evaluation such as the methods used. The objective of this study is to carry out a systematic literature review of recent studies in this area in order to provide insight for University website developer, usability researchers and higher academic institutions in all. This study focuses on researches conducted on University website usability evaluation from 2016 to 2021. Findings from this study include additional information different from existing literature review, such as, objectives of researches, common usability attributes used by usability researchers, methods of data collection and analysis, changes in data collection due to Covid-19 pandemic and the types of usability problems found. The commonly mentioned usability problems are problems related to interface design, content, navigation, performance and accessibility.

Ever since the first Short Message Service (SMS) service was introduced in 1993, its popularity has continued to soar over the years such that SMS communication now constitutes a major segment in the spectrum of telecommunication. The popularity and extensive usage has attracted the interest of many researchers to the inherent potential in harvesting data and metadata from collection of SMS corpus for the performance of linguistic, diachronic, normalization and sociolinguistic studies and also in the validation and comparison of different classifiers in SMS spam filters. However, freely available dataset where this type of information can be found for research purposes are quite difficult to obtain. This is mostly due to the confidentiality of SMS where users want to reveal as little of the contents of their phones as possible. This paper is geared towards the examination of the techniques adopted in the creation of SMS corpus and the ethical consideration involved in the protection of users' interest and privacy. For a successful SMS corpus creation, a main consideration is the requirement to protect the rights and interests of the message donors and any other person mentioned in the text messages, without altering the original text in order to gather sufficient metadata information. A review of existing work in the field was done to ascertain ethical observations adopted. Participant consent, data anonymization, and ensuring participants' safe information storage are basic ethical consideration adopted to ensure a successful SMS corpus creation.
