Developing Design Principles for a Crowd-Based Business Model Validation System [chapter]

Dominik Dellermann, Nikolaus Lipusch, Philipp Ebel
2017 Lecture Notes in Computer Science  
Our aim is thus to develop tentative design principles for crowd-based business model validation (CBMV) systems.  ...  For developing such information systems, we combine the concept of crowdsourcing with findings from research on decision support systems to propose theory-grounded design principles for a CBMV system.  ...  Decisional guidance can either be suggestive (i.e., explicitly recommending what to do) or informative, "providing pertinent information that enlightens the user's choice without suggesting or implying  ...

2022 arXiv   pre-print
However, simply integrating KGs in current KG-based RS models is not necessarily a guarantee to improve the recommendation performance, which may even weaken the holistic model capability.  ...  In this paper, we propose attentive Knowledge-aware Graph convolutional networks with Collaborative Guidance for personalized Recommendation (CG-KGR).  ...  [15] is the latest state-of-the-art propagation-based method employing a heterogeneous propagation strategy to encode diverse information for better recommendation.

Information-based network control strategies consistent with estimated driver behavior

Alexander Paz, Srinivas Peeta
2009 Transportation Research Part B: Methodological  
This study proposes a fuzzy control based methodology to determine information-based network control strategies that are consistent with the controller's objectives and its estimation of driver response  ...  That is, the effects of driver response behavior to information provision may require more meaningful strategies than those provided under the traditional dynamic traffic assignment models to reliably  ...  Iterative search procedure and fuzzy control model for the determination of the behavior-consistent information-based control strategies.  ...

Task-Guided and Path-Augmented Heterogeneous Network Embedding for Author Identification [article]

Ting Chen, Yizhou Sun
2016 arXiv   pre-print
Hence, challenges faced here are two folds: (1) how to embed the network under the guidance of the author identification task, and (2) how to select the best type of information due to the heterogeneity  ...  The guidance from author identification task for network embedding is provided both explicitly in joint training and implicitly during meta path selection.  ...  Acknowledgement We would like to thank anonymous reviewers for helpful suggestions.

Heading for new Shores: Crowdsourcing for Entrepreneurial Opportunity Creation

Dominik Dellermann, Nikolaus Lipusch, Philipp Alexander Ebel
2018 European Conference on Information Systems  
In this conceptual paper, we propose crowdsourcing for opportunity creation as a new field of further research in both in the information systems and entrepreneurship domain.  ...  Based on this assessment we develop a research agenda that highlights the need to adapt previous crowdsourcing mechanisms for the special context of entrepreneurial opportunity creation.  ...  On the one side, the entrepreneur has only insufficient information about the responses from the market or other stakeholders regarding a novel technology-based value proposition.  ...

Unsupervised Meta-path Reduction on Heterogeneous Information Networks [article]

Xiaokai Wei, Zhiwei Liu, Lichao Sun, Philip S. Yu
2018 arXiv   pre-print
Heterogeneous Information Network (HIN) has attracted much attention due to its wide applicability in a variety of data mining tasks, especially for tasks with multi-typed objects.  ...  Moreover, the reduced meta-paths can reflect the characteristic of the heterogeneous network. Previous endeavors try to reduce the number of meta-paths under the guidance of supervision information.  ...  Heterogeneous Information Network Meta-path based citation recommendation methods use the citation relationship as supervision to weight different metapaths .  ...

The Reluctant Analyst

DAN BERNHARDT, CHI WAN, ZHIJIE XIAO
2016 Journal of Accounting Research  
We provide extensive evidence that our model describes how investors believe analysts make recommendations, and that investors value private information revealed by analysts' recommendations.  ...  Publicly-available data matter far less for explaining recommendation dynamics than do the recommendation frictions and the long-lived information that analysts acquire that the econometrician does not  ...  As the first attempt to model and quantify the sources of stickiness in recommendations and the slow decay of private information, our framework allows for analyst heterogeneity in their valuation models  ...
