Electronic Markets on big data services
In the last editorial, the scenario was similar: two special issues were combined in one final issue and the editorial piece provided an opportunity to reflect about the relationship between these two special themes. Issue 27/2 included the special issues on supply chain management and on the academic publishing market and the flow perspective from supply chain management was found valuable for identifying and eliminating shortcomings in current publishing processes (Alt 2017). The present issue now comprises one special issue on “Service oriented e-business development” and another on “Big Data Analytics in Electronic Markets”. Obviously, both topics – service-orientation as well as big data – are more than multifaceted in nature and have a significant legacy. The following aims to provide some additional structure to the special issue topics and to explore relationships that partially are also addressed in the contributions of the special issues.
Data in electronic markets
Although the term big data has only received broad attention in the last five to ten years, the underlying growth of data has been a topic of concern since the mid-twentieth century. The projections on the growing number of scientific papers and journals as well as the overall inventories in libraries led to the notion of “information explosion” and in 1975 it was found “that information supply is increasing much faster than information consumption”. Information technology (IT) was successively recognized important in efficiently handling, storing and retrieving this amount of data (Press 2013). In this vein, Bryson et al. (1999) discuss data storage and compression techniques under the title “big data for scientific visualization”, which they see as a prerequisite for obtaining scientific insights. Today, the world of big data still distinguishes between the characteristics of the data (e.g. the well-known three V’s for volume, variety, and velocity), the technological infrastructure (e.g. the database technologies, such as Hadoop, Hana or System G) and the analytical techniques for analyzing and processing the data (e.g. statistical analytics, ontology engineering or text recognition).
“In July 1998, top officers of the Sabre Group, operator of the Sabre reservation system, gave an interview to PC Week in which they spoke about a planned project intended to provide the airline and other industries with a treasure trove of passenger information – “a potential gold mine.” By knowing who is flying where, when and for how much money, they explained, Sabre could gather valuable data to sell to airlines and other businesses, such as travel agencies, hotels and real estate firms. Sabre could find, for example, who is flying to a specific city in the next three weeks.” (Swift 2001, 227).
Centralized and decentralized markets
As mentioned above, providers of centralized platforms are also in a position to develop the collection and analysis of data on their platform into a business in itself. Similar to Sabre, who decided against selling passenger data in 1998, many electronic marketplaces are cautious to offer such data services. At the same time, other companies have decided to pursue this business model. For example, Helloprofit, Sellics or Terapeak process and sell data from marketplaces, such as Amazon or Ebay. The topic of emerging markets for personal data has also been the special theme of an exciting issue of Electronic Markets in 2015. In their preface, the guest editors report that electronic markets exist for trading personal data itself: “On every ordinary day, Blue Kai transacts over 75 million online auctions for personal information. The company […] says it owns 750 million user profiles […] and it processes more than 30,000 attributes about these users” (Spiekermann et al. 2015, p. 91).
Interestingly, mining interaction is not limited to centralized electronic market platforms, but may also occur in decentralized markets, which feature a topology that foresees bilateral relationships among the parties involved. These direct interactions omit an intermediary and the price premium that is typically demanded by marketplace providers. On the downside is that the typical functions of a market, i.e. matching of buyers and sellers, facilitation of transactions, and provision of an institutional infrastructure (Bakos 1998, p. 35), need to be fulfilled by other mechanisms and/or actors. Among the examples are standards for product descriptions and trading procedures, such as contracting, settlement, identity and trust, as well as the programs, which embody these standards. While early approaches to decentralized markets have applied agent technology, e.g. in the fields of file sharing systems (Quiring et al. 2008) or in freight transportation (Föhring and Zelewski 2015), more recently internet of things (IoT), distributed ledger (DLT) or Blockchain technologies have spread (e.g. in the energy wholesale business (Peck 2017)). Due to their ability to secure trust in distributed settings, they were referred to as the “trust machine” (Economist 2015) as well as the “decentralized internet” (Carlson-Wee 2017). Although establishing profiles of customers and trading data has become more difficult in this setting, big data technologies have provided useful in analyzing decentralized transactions as well. Among the examples are the mining of EDI transactions (Engel et al. 2013) as well as of DLT transactions. For example, the company Chainalysis claims to have retrieved bitcoins that were lost during the bankruptcy of the bitcoin exchange platform Mt.Gox with their Blockchain monitoring solution (Redman 2017). Using these technologies, decentralized ledger databases could be analyzed regarding other data elements and data providers could again compile and sell profiles similar to the case of centralized markets.
Service-orientation and big data
Selling data to other businesses brings us to our second theme, service-orientation. It was in 2010, that Electronic Markets already published a special issue on “Service-orientation in electronic markets”. The preface described service-orientation as a cross-disciplinary concept that is primarily grounded in business, engineering, technology and the social sciences (Alt et al. 2010, p. 177). Two perspectives shall be distinguished.
From an economic background, service industries are distinguished from goods-based industries. Services are regarded as immaterial in nature and relying on usage and the close interaction between the provider and the consumer of a service. More broadly, services may be conceived as offerings on the market that consist of “dynamic configurations of resources (people, technology, information, organizations) connected internally and externally through value propositions” (Barile et al. 2016, p. 657). This bundling of resources also led to the notion of service systems. In the context of the (big) data services mentioned above, the value propositions of these providers may be termed as “big data as a service”. To support the transaction process, the service system of an electronic market bundles services in the areas of search, process/allocation support and infrastructure (Alt et al. 2010, see also Fig. 1). Possible value propositions for big data services might pertain to offering storage infrastructure (e.g. provision of Hadoop and Spark clusters on Amazon Web Services and Microsoft Azure), analytic functionalities (e.g. provision of statistical tools as managed solution based on cloud storage) or application data (e.g. provision of consolidated/aggregated data on markets, products and/or customers).
Recent research in service science has recognized that service systems are typically linked with other service systems (Barile et al. 2016). This may occur in dyadic relationships, which are typical for business process outsourcing as well as within network settings, which are typical for electronic markets that connect multiple buyers and sellers in a more or less dynamic fashion to meet the need of one or multiple consumers. These networked service systems may occur in centralized and decentralized electronic market environments. In addition, ecosystems have been introduced in the service science literature as a third level besides service systems and service networks. These ecosystems often also include electronic platforms, which support the integration of many resources (Barile et al. 2016, p. 654ff). This is apparent in production industries where goods and service are increasingly interrelated, e.g., as product-enabled services or ‘servitization’ of products or product-service-bundlings. These services are based on big data analytics, e.g., real time data generated by so-called cyber-physical systems (CPS) or IoT. Consequently, a service-related logic has become more and more common and integral to both business model design and innovation.
“Big data need to be viewed as a service, providing a lens for seeing the market and a channel to listen to its voice. As a service, big data also can reveal service ecosystems in real time, enabling us to see and hear the sounds of the assembly and disassembly of service ecosystems. […] Developing big data methodology and techniques thus can benefit the viability of service systems, the creation and change of service networks, and thus, our understanding of service ecosystems.”
Special issue articles
After this general reflection on the relationship between big data and service-orientation the two special themes of the present issue of Electronic Markets comprise three articles each and are introduced by prefaces from the respective guest editors. The special issue on “Service oriented e-business development” was guest edited by our senior editor Doug Vogel and Xitong Guo, both from Harbin Institute of Technology, China, Jing Zhao and Zhen Zhu, both from China University of Geosciences, Wuhan, and Jianqing Chen, University of Texas at Dallas. Two papers contribute examples from service industries and one papers analyzes a service platform for crowdsourcing regarding the competition intensity in contest. Interestingly, the extraction of customer opinions and product reviews in B2C electronic commerce also represents a link to big data topics, thus to the second special theme of this issue.
The second special issue addresses "Big Data Analytics in Electronic Markets" and was organized by Eric W.T. Ngai, The Hong Kong Polytechnic University, Hong Kong, China, Angappa Gunasekaran, University of Massachusetts Dartmouth, USA, Samuel Fosso Wamba, NEOMA Business School, France, Shahriar Akter, University of Wollongong, Australia, and Rameshwar Dubey, Symbiosis International University, India. In their position paper published in issue 26/2, two of these guest editors laid the ground by providing a systematic review and research agenda in the area of Big Data Analytics in the context of electronic markets and electronic commerce (Akter and Wamba 2016). The articles are looking at applying big data analytics to multimodal mobility platforms and predicting user behavior as well as on the measurement of investor sentiment in stock markets. We would like to express our gratitude to all guest editors for organizing the two special issues.
Finally, we would like to announce three recent developments at Electronic Markets. First, we appreciate that Electronic Markets’ journal impact factor for 2016 increased to 1.864, which marks another remarkable improvement of some 33% compared to 2015. As described in the editorial of issue 26/2, the impact factor 2016 represents how often Electronic Markets papers published in the two previous years, i.e. 2015 and 2014, were cited in indexed journals during 2016 (Alt et al. 2016). Second, in the annual editorial board meeting of Electronic Markets held at ECIS 2017 in Guimarães, Portugal, enhancements of the editorial board were decided. It is an honor to welcome the following colleagues: Ulrike Baumöl (Fernuniversität Hagen, Germany) as new Senior Editor, Maria Madlberger (Webster Vienna Private University, Austria) and Mark de Reuver (Delft University of Technology, Netherlands) as new Associate Editors and Anastasia Constantelou (University of the Aegean, Greece), Christiane Lehrer (University of St. Gallen, Switzerland), James E. Richard (Victoria University of Wellington, New Zealand) and Nils Urbach (University of Bayreuth, Germany) as new members of the editorial board. Thanks to all of them for accepting these assignments. Third, we are indebted to Carsta Militzer-Horstmann, who acted as Executive Editor of Electronic Markets between August 2014 and June 2017. Authors, editors and reviewers alike applauded Carsta’s excitement for Electronic Markets and we now wish her all the best in finishing her Ph.D. thesis. At the same time, we are happy to welcome Maxi Herzog as new Executive Editor. Maxi has already been Assistant Executive Editor since March 2017 and successively took over the tasks from Carsta. She was already responsible for finalizing this issue, which we hope you enjoy reading.
