They often provide online stores so that the third-party developments can be exposed to users directly. The resulting ecosystems differ significantly from each other in their architectural designs because their providers differ in terms of business goals and contexts. Until now, this architectural diversity and rationale behind it are not well-understood. Therefore, it is not clear which software features contribute to ecosystem’s success with respect to certain business goals and context. This hinders systematic creation of ecosystems in the future. Thus, decision-making becomes too risky; for future ecosystem providers, which may lead to creation of inefficient ecosystems that lack critical features, and for third-party providers to rely on ad-hoc choices while deciding on suitability of an ecosystem for their future career. In this paper, we introduce three design patterns for store- oriented software ecosystems by classifying the design decisions, business goals, and context of 111 store-oriented software ecosystems. Each design pattern provides an architectural solution to achieve a different business goal while supporting a different context. We discuss how the design patterns are applied together in order to achieve more business goals. Our work supports ecosystem and third-party providers by sharing practice-proven architectural solutions, helping them to take informed architectural decisions and reduce technical risks."}],"language":[{"iso":"eng"}],"series_title":"To appear","author":[{"id":"36399","last_name":"Jazayeri","first_name":"Bahar","full_name":"Jazayeri, Bahar"},{"full_name":"Zimmermann, Olaf","last_name":"Zimmermann","first_name":"Olaf"},{"full_name":"Küster, Jochen","first_name":"Jochen","last_name":"Küster"},{"last_name":"Engels","first_name":"Gregor","full_name":"Engels, Gregor","id":"107"},{"first_name":"Dennis","last_name":"Kundisch","full_name":"Kundisch, Dennis","id":"21117"},{"last_name":"Szopinski","first_name":"Daniel","full_name":"Szopinski, Daniel","id":"36372"}],"year":"2018","title":"Patterns of Store-oriented Software Ecosystems: Detection, Classification, and Analysis of Design Options","date_updated":"2022-01-06T07:01:57Z","place":"Valparaíso, Chile","citation":{"chicago":"Jazayeri, Bahar, Olaf Zimmermann, Jochen Küster, Gregor Engels, Dennis Kundisch, and Daniel Szopinski. “Patterns of Store-Oriented Software Ecosystems: Detection, Classification, and Analysis of Design Options.” In <i>The Latin American Conference on Pattern Languages of Programs (SLPLoP)</i>.

Customers who review local offline businesses such as restaurants can identify themselves as locals or travelers and thus implicitly assign themselves to a specific reviewer group. This study investigates the relationship between identifying as a local and the perceived usefulness of their online reviews. Using data from Yelp.com, we empirically test hypotheses derived from attribution theory. Our results suggest that neutral and negative reviews by locals tend to be perceived as more useful than reviews by travelers. Positive reviews by locals, however, are not perceived as more useful.

Although the effect of the average and the number of consumer ratings on future product pricing and demand have been studied with some conclusive results, the effects of the variance of these ratings are less well understood. We develop a model which considers durable goods that are characterized by three types of attributes: search attributes, experience attributes, and transformed attributes the latter are conventional experience attributes that are transformed by consumer ratings into attributes that can be searched. Using informed search attributes to refer to the combination of search attributes and transformed attributes, we consider two sources of variance of consumer ratings: taste differences about informed search attributes and quality differences in the form of product failure representing experience attributes. We find that (i) optimal price increases and demand decreases in variance caused by informed search attributes, (ii) optimal price and demand decrease in variance caused by experience attributes, and (iii) by holding the average rating as well as the total variance constant, for products with low total variance price and demand increase in the relative share of variance caused by informed search attributes. Counter to intuition, we demonstrate that risk averse consumers may prefer a higher priced product with a higher variance in ratings when deciding between two similar products with the same average rating. Finally, our model provides a theoretical explanation for the empirically observed j-shaped distribution of consumer ratings in e-commerce that differs from established explanations.","lang":"eng"}],"date_created":"2017-10-17T12:41:12Z","file":[{"file_size":882133,"access_level":"closed","file_name":"107-ConsumerRating.pdf","date_updated":"2018-03-21T13:11:08Z","relation":"main_file","content_type":"application/pdf","success":1,"file_id":"1570","creator":"florida","date_created":"2018-03-21T13:11:08Z"}],"department":[{"_id":"276"}],"type":"journal_article","status":"public","has_accepted_license":"1","publisher":"INFORMS","_id":"107","page":"984-1002","volume":29,"ddc":["040"],"user_id":"477","citation":{"chicago":"Zimmermann , Steffen, Philipp Herrmann, Dennis Kundisch, and Barry Nault. “Decomposing the Variance of Consumer Ratings and the Impact on Price and Demand.” <i>Information Systems Research</i> 29, no. 4 (2018): 984–1002. <a href=\"https://doi.org/10.1287/isre.2017.0764\">https://doi.org/10.1287/isre.2017.0764</a>.","short":"S.
