Selected articles I have published over the years in different journals.
Work at IfeM
William worked for the research institute IfeM (Institute for e-Management) in 2004, and was involved in IT projects involving corporations such as T-Mobile and Shell, often meeting with the top management and board members of those companies, as an expert for SaaS, SEO and Software Development.
IfeM was running many Internet portals at that time, and publishing articles. William also took the liberty of writing for them, later becoming a partner. Some the selected articles published during that time are listed here.
Work at Investor Village
In 2001 William worked for Prof. Dr. Max Otte at the investor portal Investor Village, run by one of Germany’s largest communication companies Freenet.
While he was a software developer responsible for building the CMS and real time stock exchange course graphics using APIs, he was aware that he was working for the financial legend Max Otte. William took the chance to learn everything he could about financing, investing and the stock market, and was later able to write articles as a financial analyst.
Some of these articles from that period are listed the end of this list.
A selection of articles William has published for the Social Media Magazine.
The History of the Social Media Magazine
During his time at infospeed, the Marketing Department was looking for an idea to address their clients with quarterly information. William was sure that his clients — all of them top management — wouldn’t have time to read newsletters or any other quarterly agency information.
So, William came up with the idea of an independent magazine and founded the first Social Media Magazine in Germany in 2010. It was such a success that William had to form a publishing company for it. Almost all his clients knew the magazine without knowing though that the company infospeed was behind it. When in need to demonstrate their USPs — like during a pitch — the team members would surprise their potential clients or leads by telling them that it is infospeed that owns and writes the magazine.
During that time, Dr. William Sen wrote articles for the magazine.
Give years after the first issue of the magazine was released, it was still one of best selling and profitable magazines of its kind, and most importantly: every employee in the company loved it.
William’s articles published on the Social Media Magazine from 2010-2015:
Object of our empirical research study are depicted and provoked emotions in videos. Are users able to index such emotions consistently? Are the users’ votes usable for emotional video retrieval?
We worked with a controlled vocabulary for nine basic emotions (love, happiness, enjoyment, surprise, desire, sadness, anger, disgust, and fear), a scroll bar for adjusting the emotions’ intensities, and the approach of broad folksonomies. Different users tagged the same videos. The test persons had the task to index the emotions of 20 videos (reprocessed movies from YouTube). We got data from 776 participants and could analyze all in all 279,360 scroll bar values. The consistency of the users’ votes is very high; there are stable tag distributions for the emotions of the particular videos. The final shape of the distributions will be reached by the tagging activities of only few users (less than 100). Applying the approach of power tags it is possible to separate the pivotal emotions of every document – if there is any feeling at all. Those documentspecific emotions establish the basis of an emotional information retrieval (EmIR) system.
A business’ need for knowledge and information from the Social Web has increased. Even thought there is a huge amount of data available on the Social Web, much of it has no standardized structure and is therefore unsuitable for social media analysis and data mining.
Thus, a new industry of specialized search engines has been developed. Other than popular search engines, these specialized technologies are able to crawl data in a structured way. This paper deals with specialized crawlers and technologies. It also shows and explains the social media monitoring tool called web2monitor.
In this paper, a concept for the development of KPIs for measuring Internet forums and their postings will be presented.
Based on the former research of Dr. William Sen, this paper discussed the importance and reach of how Internet forums impact a company’s brand and reputation. This research deals with this topic by developing real KPIs to determine what kind of Internet forum should be monitored by companies and when. This method will also demonstrate how companies can benefit from such KPIs and how it can be implemented into a management information system.
Will link popularity of search engines in the future no longer aim to merely list quantitative information to the users, but to gain the satisfaction through collection of relevant information? Will this mean that website operators lose the ability through the use of certain methods to influence their listing in search engines? This paper examines these questions.
If they concentrate on more content based information, rather than classic search engine optimization techniques, search engines such as Google may be easily manipulated. On this basis, the two practical methods of SEM / SEO (Search Engine Marketing / Search Engine Optimization) are being researched and explained in this thesis. The research deals with all the new methods of content-based SEO and describes their use based on different scientific models.
Articles by William Sen he wrote for the Amiga Magazine in the 8-bit era.
Amiga Plus was the famous Commodore Amiga magazine in Germany. William Sen had his first Commodore Amiga computer when he was 16, and he loved it ever since.
He was picked up by the Amiga magazine publisher after the success of my book “Hackerland”. Even though he was fully employed by several IT companies at that time, he took this honor and wrote in his spare time for the sake of his childhood memories.
