Theorists often speculate why open source and free software project contributors give their work away. Although contributors make their work publicly available, they do not forfeit their rights to it. Community managed software projects protect their work by using several legal and normative tactics, which should not be conflated with a disregard for or neglect of intellectual property rights. These tactics allow a project’s intellectual property to be publicly and freely available and yet, governable. Exploration of this seemingly contradictory state may provide new insight into governance models for the management of digital intellectual property. 相似文献

A technique of online instruction and assistance to bibliographic data base searchers called Individualized Instruction for Data Access (IIDA) is being developed by Drexel University. IIDA assists searchers by providing feedback based on real-time analysis while searches are being performed. Extensive help facilities which draw on this analysis are available to users. Much of the project's experimental work, as described elsewhere [1–3], is concerned with the process of searching and the behavior of searchers. This paper will largely address itself to the project's computer system, which is being developed by subcontract with the Franklin Institute's Science Information Services. 相似文献

This paper explores the integration of textual and visual information for cross-language image retrieval. An approach which automatically transforms textual queries into visual representations is proposed. First, we mine the relationships between text and images and employ the mined relationships to construct visual queries from textual ones. Then, the retrieval results of textual and visual queries are combined. To evaluate the proposed approach, we conduct English monolingual and Chinese–English cross-language retrieval experiments. The selection of suitable textual query terms to construct visual queries is the major issue. Experimental results show that the proposed approach improves retrieval performance, and use of nouns is appropriate to generate visual queries. 相似文献

This paper summarizes the pilot stage of a microeconomic study of the innovation performance through time of young, high-technology Israeli firms. It reports some results for a successful firm designing, producing and selling electronic instruments and systems. The paper begins by surveying some of the difficulties surrounding the collection and organization of data on R&D projects. One of them concerns the definition of the ‘Unit for Analysis’ - the R&D project. Three criteria are suggested for dividing the stream for innovative activities into R&D projects, and these are applied to group the tens of products, accessories and systems included in the analysis into nine projects. The paper subsequently defines a measure of “direct” project performance or profitability estimate - discounted operating profits per unit of fixed costs - and provides estimates based on R&D and sales data for the products of each project. The final sections analyze the variation of project profitability through time. The increasing profitability observed across generations of a product class is attributed to the adaptability of the firm to changes in the environment, particularly to the availability of new technology which requires the swift design and sale of more complex products. The qualitative history of the various projects suggests that this adaptability is due, to a large extent, to the skills, infrastructure and reputation of the firm accumulated from prior projects, i.e. that the “indirect” profitability of the latter is high. Some estimates of the indirect profitability of early projects are presented. A comparison of the spin-off mechanisms observed in the firm analyzed with those observed in firms of other industries is also undertaken. 相似文献

This study examined how participation in open innovation communities influences the innovative and financial performance of firms commercializing open source software. Using an original dataset of open source companies in the Netherlands, I found that the community participation–performance relationship is curvilinear. In addition, results indicate that extensive technical participation in open source projects is more strongly related to performance for firms that also engage in social (“offline”) community activities, for companies of larger size, and for firms with high R&D intensities. Overall, this research refines our understanding of the boundary conditions under which engagement in community-based innovation yields private returns to commercial actors. 相似文献

Open source is an example of user-centric innovation initiated by an individual or group of users to satisfy their specific needs; the more a software evolves towards a stable release able to address the requirements of its developers, the more successful the project. In this paper we use a large data-set obtained from SourceForge.net to estimate the relationship between a series of different characteristics of OS projects and the probability of evolution of the source code from a preliminary release to a mature version. We show that while projects distributed under highly restrictive licensing terms (GPL) have a significantly smaller probability of reaching a stable release, applications towards sophisticated users have a larger probability of evolving in the development status. Interestingly, we find that the size of the “community of developers” increases the chances of progress but this effect decreases as the community gets larger, a signal of possible coordination problems. 相似文献

Open Source Software (OSS) has had a profound impact on the way in which software is developed and consequently on the perception of software development. This paper starts with a brief discussion of the eclectic techniques and processes, combinations of which may be used for OSS projects. A ‘real-world’ context will be examined using ‘Reflective Analysis’ focusing on the research and development team present within the Business, Logistics and Information Systems (BLIS) department at The University of Bolton. The reflective analysis explores some assumptions inherent in OSS development. Drawing on findings from experience, industry and background research, an attempt will be made to provide an insight into how in a small team, the use of OSS and associated techniques can lead to the successful development of software. Whilst early results show that smaller OSS projects may appear to have little or no formal structure with closer investigation it is clear this is not the case. Without at least some degree of management, the teams experience indicates that such projects may be prone to failure. 相似文献

This paper presents a robust and comprehensive graph-based rank aggregation approach, used to combine results of isolated ranker models in retrieval tasks. The method follows an unsupervised scheme, which is independent of how the isolated ranks are formulated. Our approach is able to combine arbitrary models, defined in terms of different ranking criteria, such as those based on textual, image or hybrid content representations.We reformulate the ad-hoc retrieval problem as a document retrieval based on fusion graphs, which we propose as a new unified representation model capable of merging multiple ranks and expressing inter-relationships of retrieval results automatically. By doing so, we claim that the retrieval system can benefit from learning the manifold structure of datasets, thus leading to more effective results. Another contribution is that our graph-based aggregation formulation, unlike existing approaches, allows for encapsulating contextual information encoded from multiple ranks, which can be directly used for ranking, without further computations and post-processing steps over the graphs. Based on the graphs, a novel similarity retrieval score is formulated using an efficient computation of minimum common subgraphs. Finally, another benefit over existing approaches is the absence of hyperparameters.A comprehensive experimental evaluation was conducted considering diverse well-known public datasets, composed of textual, image, and multimodal documents. Performed experiments demonstrate that our method reaches top performance, yielding better effectiveness scores than state-of-the-art baseline methods and promoting large gains over the rankers being fused, thus demonstrating the successful capability of the proposal in representing queries based on a unified graph-based model of rank fusions. 相似文献

Online open source software platforms, such as Sourceforge.net, play a vital role in creating an ecosystem that enables the creation and growth of open source projects. However, there is little research exploring the interactions between open source stakeholders and the platform. We believe that the sustainability of the platform crucially depends on financial incentives. While platforms can obtain these incentives through multiple means, in this paper we focus on one form of financial incentives—voluntary monetary donations by open source community members. We report findings from two empirical studies that examine factors that impact donations. Study 1 investigates the factors that cause some community members to donate and not others. We find that the decision to donate is impacted by relational commitment with open source software platform, donation to projects and accepting donations from others. Study 2 examines what drives the level of donation. We find that the length of association with the platform and relational commitment affects donation levels. 相似文献

With rapid advancements in information and communication technology, open collaboration has become easier, thereby allowing people to participate through internet platform. Open source software is one of the representative examples of open collaboration. In this research, we examine the antecedents of innovation performance for open source software development organizations on Github (www.github.com), which is a leading web service for the open collaborations of developers. From the perspective of resource allocation, this study investigates effective governance strategies to allocate developers to multiple projects within an organization. Overall, we find that the organization with high performance have a small number of developers to participate in most projects and most developers to participate in a small number of projects. 相似文献

Projects and firms as discordant complements: organisational learning in the Munich software ecology
In current theorising, projects and firms are understood as “learning organisations”. Although the learning function can be regarded as constituent for both organisational forms, the specific learning mechanisms are connected with opposing features (e.g. long-term, trustful collaboration versus short cyclical, disruptive collaboration). Referring to the first results of qualitative research conducted on the Munich software cluster, this paper aims to explore the functional interplay between projects and firms with regard to organisational learning. The main thesis is that processes of improvement, failure eradication and knowledge accumulation are more likely to take place in firms whereas processes of structural change are more likely to be organised in a project. In complementing one another these functions, however, also generate inconsistencies like contravening learning incentives or contingency traps. Therefore, projects and firms may be regarded as “discordant complements”. 相似文献

Knowledge source selection is a complex phenomenon that is often addressed from an organizational viewpoint; however, we know little about knowledge-seeking practices at the individual level. We examined knowledge sourcing in new product development (NPD) teams at the micro-level through the lens of psychological safety (PS). We investigated 1345 individuals at 85 software development teams in Pakistan to demonstrate how different levels of PS affected knowledge sourcing from three groups: within the team; within the organization; and outside the organization. Our results showed that individuals with high PS levels were more inclined to consult fellow team members and individuals with low PS levels were more likely to choose external sources. We also examined how the diversity of a team's composition affected the relationship between psychological safety and knowledge source selection. We explored the implications of these findings for managerial practice. 相似文献

Estimating the similarity between two legal case documents is an important and challenging problem, having various downstream applications such as prior-case retrieval and citation recommendation. There are two broad approaches for the task — citation network-based and text-based. Prior citation network-based approaches consider citations only to prior-cases (also called precedents) (PCNet). This approach misses important signals inherent in Statutes (written laws of a jurisdiction). In this work, we propose Hier-SPCNet that augments PCNet with a heterogeneous network of Statutes. We incorporate domain knowledge for legal document similarity into Hier-SPCNet, thereby obtaining state-of-the-art results for network-based legal document similarity.Both textual and network similarity provide important signals for legal case similarity; but till now, only trivial attempts have been made to unify the two signals. In this work, we apply several methods for combining textual and network information for estimating legal case similarity. We perform extensive experiments over legal case documents from the Indian judiciary, where the gold standard similarity between document-pairs is judged by law experts from two reputed Law institutes in India. Our experiments establish that our proposed network-based methods significantly improve the correlation with domain experts’ opinion when compared to the existing methods for network-based legal document similarity. Our best-performing combination method (that combines network-based and text-based similarity) improves the correlation with domain experts’ opinion by 11.8% over the best text-based method and 20.6% over the best network-based method. We also establish that our best-performing method can be used to recommend/retrieve citable and similar cases for a source (query) case, which are well appreciated by legal experts. 相似文献

In this article we establish three claims: (1) When the target software is proprietary, in the absence of other overriding ethical considerations, the identification of a vulnerability and the development, sale, and purchase of non-zero-day exploits are ethically justified; (2) when the target software is Free/Libre/Open Source, the buying and selling of vulnerabilities can be ethically justified only in a very narrow situation, while the sale and purchase of non-zero-day exploits is ethically justified absent of any other overriding information; and (3) democratic governments should promote legislation that either incentivizes corporate in-house vulnerability identification and mitigation programs or requires firms to more fully absorb the societal costs of insecure software. 相似文献
