“…The rising popularity of cyber-crime in Nigeria (Longe et al, 2009) can be connected to the current state of economic instability, high unemployment rate among able-bodied youths, erosion of traditional values of integrity, and quick-money syndrome, etc. To curb these illegal activities, institutions such as the Economic and Financial Crimes Commission (EFCC) were established in Nigeria and have recorded several arrests and prosecution of cyber-crime suspects (Omorogbomwan, 2018).…”

BackgroundSocial media opinion has become a medium to quickly access large, valuable, and rich details of information on any subject matter within a short period. Twitter being a social microblog site, generate over 330 million tweets monthly across different countries. Analyzing trending topics on Twitter presents opportunities to extract meaningful insight into different opinions on various issues.AimThis study aims to gain insights into the trending yahoo-yahoo topic on Twitter using content analysis of selected historical tweets.MethodologyThe widgets and workflow engine in the Orange Data mining toolbox were employed for all the text mining tasks. 5500 tweets were collected from Twitter using the 'yahoo yahoo' hashtag. The corpus was pre-processed using a pre-trained tweet tokenizer, Valence Aware Dictionary for Sentiment Reasoning (VADER) was used for the sentiment and opinion mining, Latent Dirichlet Allocation (LDA) and Latent Semantic Indexing (LSI) was used for topic modeling. In contrast, Multidimensional scaling (MDS) was used to visualize the modeled topics. ResultsResults showed that "yahoo" appeared in the corpus 9555 times, 175 unique tweets were returned after duplicate removal. Contrary to expectation, Spain had the highest number of participants tweeting on the 'yahoo yahoo' topic within the period. The result of Vader sentiment analysis returned 35.85%, 24.53%, 15.09%, and 24.53%, negative, neutral, no-zone, and positive sentiment tweets, respectively. The word yahoo was highly representative of the LDA topics 1, 3, 4, 6, and LSI topic 1.ConclusionIt can be concluded that emojis are even more representative of the sentiments in tweets faster than the textual contents. Also, despite popular belief, a significant number of youths regard cybercrime as a detriment to society.

This article speaks to the societal implications of technology by discussing the problems presented by cybercrime. It identifies a twofold problem. The first is that the proliferation of cybercrime is outstripping the pace at which governments can respond. The second is that there is a tendency to respond to issues relating to cybercrime on a superficial level without the appropriate technical understanding of the elements of cybercrime. This paper proposes that one of the ways of tackling cybercrime is to adopt the Routine Activities Theory, particularly the element of target suitability. This paper proposes that once a suitable target has been identified, the Gordon & Ford categorisation of cybercrimes be adopted as a policy framework for legislation and conventions. It illustrates the proposition by applying the categorisation to the South African Cybercrimes Bill.
