Misinformation related to vaccines has been shown to potentially negatively impact public perceptions and intentions to vaccinate in many contexts including COVID-19 vaccination in Ghana. Psychological inoculation – where recipients are warned about the misleading techniques used in misinformation – is a potential intervention which could preemptiv...
Identification of people at risk of cardiometabolic diseases is a major clinical need. Such individuals can benefit from tailored treatments that can potentially reduce their risk, while bringing precision to predictive, preventive, and personalised medicine (PPPM). Central to preventive medicine is the new concept of Suboptimal Health Status (SHS)...
The integration of the Internet into various aspects of business operations, including the public sector, is rapidly becoming a norm.

Predicting the impact of suicide on incidental witnesses at an early stage helps to avert the possible side effect. When suicide is committed in public, incidental observers are left to grapple with it. In many cases, these incidental witnesses tend to experience the emotional side effect with time. In this study, we employed a Machine learning alg...
In this paper, an intelligent e-counselling system for automatic detection of emotion in text is evaluated. A support vector machine classifier was used for the development of the e-counselling system, hence we compared the performance of the e-counselling system’s classifier with WEKA’s Multinomial Naïve-Bayes and J48 decision tree classifiers. Wh...
This chapter describes how today's technology has provided flexibility for teachers and students to engage in academic discourse irrespective of the location. However, there is an ongoing debate regarding the influence of mobile devices on students' academic engagement and performance. Following this debate, these authors empirically investigate th...
Emotions are a core semantic component of human communication. Since counsellors are humans we assume that their own state of emotions could affect their intuitional effort when taking decisions concerning their clients. Therefore, the accuracy of detected emotions by counsellors could be doubtful. And this highlights the need for complementing the...
Given the challenges associated with the analysis of emotions in text by counsellors, we present an intelligent e-counselling system for automatic detection of emotions and sentiments in text. The system- EmoTect- was developed using a supervised support vector machine learning classifier. Therefore, students’ life stories were collected and develo...
Students’ academic achievement is largely driven by their social phenomena, which is shaped by social influence and opinion dynamics. In this paper, we employed a machine learning technique to detect social influence and sentiment in text-based students’ life stories. The life stories were first pre-processed and clustered using k-means with euclid...
While efforts are being made to effectively integrate information and communication
technologies into personal-social counselling, this thesis contextualises the
application of human language technologies for counselling delivery. With this in
mind, a web-based e-counselling system has been developed for aiding counsellors
in their decision making...
We investigate the influence of counsellors’ state of emotions on their emotion perception through annotation agreement of emotions in text. Selected counsellors were tasked to annotate sample corpora from International Survey on Emotion Antecedents and Reactions (ISEAR), and students’ life stories. We explore the intra and inter-counsellors’ annot...
Hackathon is an event where programmers and subject field specialists collaborate intensively in teams with the ultimate aim to create and design fresh ICT (information and communication technology) based solutions to a given task in a limited time.

The informal sector employs the major part of workers in developing countries. Street trading is a common form of informal work. Despite its huge economic value in developing countries, little research is being done to improve street traders' empowerment and entrepreneurship. Also, development informatics is over-focused on social development and u...
The urge to progressively motivate e-counselling in schools is somewhat dependent on students’ behavioral intention towards the use of the technology. Unified Theory of Acceptance and Use of Technology (UTAUT), a model for predicting behavioral use and acceptance of Information Technology system, was developed through a review and validation of eig...
The paper presents a naive algorithm for Travelling salesman problem (TSP) using a dynamic programming approach (brute force). The idea is to compare its optimality with Tabu search algorithm. In the end, the results of the experiment show that brute force algorithm produces a relatively high optimal solution to that of the Tabu search. However, it...
Given the current global trend of mimicking real life situations into digital counselling games and its related digital counselling platforms, we decided to contextually understand from the Ghanaian Senior High School students, their life challenges arising from their life stories.

I have over 8 citations to my published papers, but it seems its not reflected on my citation page. Is there any possibility of manually inserting or adding the cited papers to my page or get the citations on? Any ideas would be deeply appreciated.
I am doing semi-supervised classification with WEKA. The test set of my data (twitter) is unlabeled (no class assigned) but replaced with (?). I used WEKA to convert the test data from csv to arff file, which sets automatic datatype of 'string' to the class attribute. When I try to run it after creating the model with my train data it seems to give errors regarding the string datatype given to the unlabelled class attribute. My question is what datatype is suitable for the class attribute in '?' to avoid glitches?
