Javier Sanz-Cruzado, Sofía M. Pepa, Pablo Castells
2018 Companion of the The Web Conference 2018 on The Web Conference 2018 - WWW '18  
We consider further utility dimensions beyond prediction accuracy, namely novelty and diversity.  ...  Link prediction has mainly been addressed as an accuracy-targeting problem in the social networks field.  ...  structural diversity brought by link prediction.  ...

Linking the Divergent and Convergent Processes of Collaborative Creativity: The Impact of Expertise Levels and Elaboration Processes

Lauren E. Coursey, Ryan T. Gertner, Belinda C. Williams, Jared B. Kenworthy, Paul B. Paulus, Simona Doboli
2019 Frontiers in Psychology  
However, consistent with our theoretical model final product novelty was influenced by the number and novelty of the replies in the divergent phase.  ...  Low expertise groups demonstrated the most novelty in the divergent phase. Final product novelty was also associated with sports words used in discussions during the convergent phase.  ...  Any opinions, findings, and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of the National Science Foundation.  ...

A knowledge reuse framework for improving novelty and diversity in recommendations

Apurva Pathak, Bidyut Kr. Patra
2015 Proceedings of the Second ACM IKDD Conference on Data Sciences - CoDS '15  
However, recent study shows that novelty and diversity in recommendations are equally important factors from both user and business view points.  ...  In this paper, we introduce a knowledge reuse framework to increase novelty and diversity in the recommended items of individual users while compromising very little recommendation accuracy.  ...  However, minimum predicted rating selection is found to be outperforming others in providing diversity and novelty.  ...

Coevolution of Network Structure and Content [article]

Chun-Yuen Teng, Liuling Gong, Avishay Livne, Celso Brunetti, Lada A. Adamic
2012 arXiv   pre-print
We demonstrate, using time series analysis of communication in three online settings, that network structure alone can be highly revealing of the diversity and novelty of the information being communicated  ...  We find that networks with a higher conductance in link structure exhibit higher information entropy, while unexpected network configurations can be tied to information novelty.  ...  The views and conclusions contained in this document are those of the authors and should not be interpreted as representing the official policies, either ex-pressed or implied, of the U.S.  ...

R&D Production Team Composition and Firm-Level Innovation

Vikas A. Aggarwal, David Hsu, Andy Wu
2014 Academy of Management Proceedings  
We assemble a panel dataset of start-up biotechnology firms founded between 1980 and 2000, tracked from founding through 2009, to develop and test hypotheses regarding the link between team structure and  ...  We also find evidence that collaborative experience and combinatorial novelty moderate this effect, further supporting our proposed framework.  ...  novelty moderator (H3) in models (4-3) and (4-4).  ...

CReM: chemically reasonable mutations framework for structure generation

Pavel Polishchuk
2020 Journal of Cheminformatics  
Here we developed a new framework of fragment-based structure generation that, by design, results in the chemically valid structures and provides flexible control over diversity, novelty, synthetic complexity  ...  On the other hand, conventional reaction-based approaches result in synthetically feasible compounds but novelty and diversity of generated compounds may be limited.  ...  Acknowledgements The author thanks Guzel Mindubaeva for the implementation and testing of some functions and Dr. Olena Mokshyna for critical reading of the manuscript.  ...

Accurate and Novel Recommendations

Amin Javari, Mahdi Jalili
2014 ACM Transactions on Intelligent Systems and Technology  
Recently, the community has been paying attention to diversity and novelty of recommendation list as key characteristics of modern recommender systems.  ...  The other algorithm, denoted as novelty and population based filtering algorithm, is to move towards items with low popularity in past time steps that are predicted to become popular in the future.  ...  Recommendation task is similar to link prediction problem in networked structures [Liben-Nowelly and Kleinberg 2003; Lü and Zhou 2011] .  ...

2020 arXiv   pre-print
And are the innovations of underrepresented groups adopted and rewarded? Our analyses show that underrepresented groups produce higher rates of scientific novelty.  ...  Prior work finds a diversity paradox: diversity breeds innovation, and yet, underrepresented groups that diversify organizations have less successful careers within them.  ...  Nielsen, Anthony Lising Antonio, James Zou, and Londa Schiebinger.

Where do novelties come from? A social network analysis of Transnational Municipal Networks in global climate governance

Marielle Papin
2020 Earth System Governance  
Findings suggest that the most central TMNs, which also have diverse contacts, can draw on huge volumes of diverse information to generate novel governance instruments and evolve.  ...  Scholars have discussed their effects, including their capacity to generate novelties. Yet, some confusion remains in this area.  ...  In CAS, both structure and agents matter. The impact of certain attributes, actions or behaviours is hard to predict. Complexity approaches and network theory are complementary.  ...

2016 ACM Transactions on Intelligent Systems and Technology  
In addition, we show how the semantic expansion of the initial descriptions helps in achieving much better recommendation quality in terms of aggregated diversity and novelty.  ...  Tags and textual descriptions are exploited to extract and link entities to external graphs such as WordNet and DBpedia which are in turn used to semantically enrich the initial data.  ...  due to its performances in terms of novelty and aggregate diversity.  ...

Stimulated by Novelty? The Role of Psychological Needs and Perceived Creativity

Kiki M. M. De Jonge, Eric F. Rietzschel, Nico W. Van Yperen
2018 Personality and Social Psychology Bulletin  
In contrast, those high in need for structure may experience cognitive diversity in the group as unwelcome, as diverse insights and ideas from others further increase complexity and ambiguity in the task  ...  As can be seen in Figure 3 , the positive effect of input novelty on idea diversity through perceived creativity was weaker for people high in need for structure than for those low in need for structure  ...
